The soliton beams with different wavelength and same width, if their incident point and incident slanting angle are the same, will propagate along the same periodic Z-type route in the planar waveguide. With the power of the beam increasing, the distance between two adjacent reflecting points will become longer and longer with the propagation distance and the Z-type route will lose its periodicity. When the power of a beam become fairly strong, the beam will propagate along z direction of the waveguide, and will no longer be reflected back and forth between the two boundaries of the planar waveguide. Using the characteristic that a beam injected at an inclined angle in the waveguide will propagate along different route with different power, a power switch and an optical time division demultiplexer are designed.Number of references:30Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Document type:Journal article (JA)Publisher:Science Press, 18,Shuangqing Street,Haidian, Beijing, 100085, ChinaAbstract:In order to investigate the tribological performance of laser clad coating on die steel, laser cladding techniques were adopted with Fe-based alloy powders. The tests were carried out by using laser clad layers as upper samples and GCr15 steel as low samples with HT-500 wear tester. The morphologies of wear scars were observed with optical microscopy, and the width and the depth of the wear samples were measured. In the meantime, the wear rate was calculated theoretically. Under dry sliding condition, As the tests shown, friction coefficient decreases with the load increasement gradually, and then increases. And the wear performance of 300 g load is better than that of 500 g load under dry sliding condition. Under lubricant condition, with the increasement of load, the friction coefficient decreases gradually. And the friction coefficient, wear rate and wear width under lubricant are smaller than those under dry friction with the same load.Number of references:17Main heading:Laser claddingControlled terms:Architectural design - Coating techniques - Curing - Lasers - Metal cladding - Optical microscopy - Steel - TribologyUncontrolled terms:Friction coefficient - Laser technique - Wear rateClassification code:744.1 Lasers, General - 744.9 Laser Applications - 802.2 Chemical Reactions - 931.2 Physical Properties of Gases, Liquids and Solids - 813.1 Coating Techniques - 818.3 Rubber and Elastomer Processing - 931 Classical Physics; Quantum Theory; Relativity - 815.1 Polymeric Materials - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 402 Buildings and Towers - 408.1 Structural Design, General - 535.1 Metal Rolling - 538.2 Welding - 539 Metals Corrosion and Protection; Metal Plating - 545.3 SteelDOI:10.3788/CJL20083505.0776Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The surface flatness of the undoped GaN layer has little effect on the forward voltage and output power of the LED. However, the reverse leakage current and the lifetime of the LED wafer grown on the flatter GaN layer improved evidently.

The results obtained from voltammetry show that the redox couples of V(IV)/V(V) and V(II)/V(III), as positive and negative electrodes of all vanadium flow liquid battery, respectively, have good reversibility but low current on the GP electrode, and the current can be improved by CNT. It is found from the observation of SEM that the CNT is dispersed evenly on the surface of sheet GP when they are mixed together. The best composition for the positive and the negative of all vanadium flow liquid battery determined by comparing voltammetric behavior of the composite electrodes with different content of CNT is 5:95 (w<inf>CNT</inf>/w<inf>GP</inf>) for both positive and negative electrodes.

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:The aim of this research was to investigate catalytic activity of petroleum coke, activated carbon (AC) prepared from this material, Ni supported catalyst on activated carbon (Ni/AC) in the ozonation of aqueous phase p-chlorobenzoic acid (p-CBA). Activated carbon and Ni/AC catalyst were characterized by XRD and SEM. The presence of petroleum coke did not improve the degradation of p-CBA compared to ozonation alone, but it was advantageous for p-CBA mineralization (total organic carbon, TOC, reduction), indicating the generation of highly oxidant species ({radical dot}OH) in the medium. The presence of either activated carbon or Ni/AC considerably improves TOC removal during p-CBA ozonation. Ni/AC catalyst shows the better catalytic activity and stability based on five repeated tests during p-CBA ozonation. During the ozonation (50 mg/h ozone flow rate) of a 10 mg/L p-CBA (pH 4.31), it can be more mineralized in the presence of Ni/AC catalyst (5.0 g/L), TOC removal rate is over 60% in 60 min, 43% using activated carbon as catalyst, only 30% with ozonation alone. &copy; 2008 Elsevier B.V.

CODEN:IJHEDXDocument type:Journal article (JA)Publisher:Elsevier Ltd, Langford Lane, Kidlington, Oxford, OX5 1GB, United KingdomAbstract:The result obtained from linear potential sweep indicates that magnesium in 6 M KOH solution behaves like an active-passive metal. The anodic oxidation process of magnesium and the interface structure between magnesium and solution were investigated by alternative current impedance analysis. It is found that when anodized, magnesium experiences active dissolution, passivation and secondary oxidation. In active region, magnesium dissolves actively, which is controlled by charge transfer step. In passive region, magnesium is passivated by the deposited Mg(OH)<inf>2</inf> but its oxidation controlled by charge transfer step still happens. In the secondary oxidation region, magnesium is oxidized directly to MgO, which is mix-controlled by charge transfer step and diffusion of water. &copy; 2008 International Association for Hydrogen Energy.Number of references:26Main heading:Anodic oxidationControlled terms:Charge transfer - Dissolution - Ion exchange - Light metals - Magnesium - Magnesium printing plates - Mass transfer - Metal recovery - MOS capacitors - Oxidation - PassivationUncontrolled terms:Active dissolutions - Active regions - Alkaline solution - Alternative current impedance - Diffusion of waters - Impedance analyses - Interface structures - Koh solutions - Linear potential sweeps - Oxidation processes - Passive metals - Passive regions - Secondary oxidationsClassification code:704.1 Electric Components - 714.2 Semiconductor Devices and Integrated Circuits - 745.1.1 Printing Equipment - 801.4.1 Electrochemistry - 802.2 Chemical Reactions - 802.3 Chemical Operations - 813.1 Coating Techniques - 641.3 Mass Transfer - 531 Metallurgy and Metallography - 539.2.1 Protection Methods - 541.1 Aluminum - 542.1 Beryllium and Alloys - 542.2 Magnesium and Alloys - 542.3 Titanium and Alloys - 549.2 Alkaline Earth MetalsDOI:10.1016/j.ijhydene.2008.09.087Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Four fibrous-root and four rhizomatic-root wetland plants were studied in mono-cultured microcosms which received wastewater. Fibrous-root plants had significantly greater (P &lt; 0.05) small-size root (diameter 1 mm) biomass and a larger (P &lt; 0.05) root surface area per plant than the rhizomatic-root plants and exhibited accelerated growth in both shoots and roots compared to the rhizomatic-root plants. Fibrous-root plants developed the majority of their root biomass increment within a shallower gravel medium than the rhizomatic-root plants. All plants demonstrated fast root biomass growth from July to September. The wetland microcosms planted with fibrous-root plants showed significantly higher (P &lt; 0.05) ammonium-nitrogen (NH<inf>4</inf>-N) and nitrate-nitrogen (NO<inf>3</inf>-N) removal rates from July to December than those planted with the rhizomatic-root plants. These results suggest that root characteristics of wetland plants, which are related to their shoot and root growth, root distribution, and decontamination ability, can be used in the selection of wetland plants with a higher contaminant removal capacity and in the construction of a multi-species wetland plant community. &copy; 2008 Springer Science+Business Media B.V.Number of references:33Main heading:WetlandsControlled terms:Ammonium compounds - Biological materials - Biomass - Contamination - Ecology - Forestry - Growth (materials) - Removal - Renewable energy resources - Spectroscopic analysis - WastewaterUncontrolled terms:Constructed wetland - Contaminant removal - Fibrous-root plants - Rhizomatic-root plants - Root biomass and distributionClassification code:714.2 Semiconductor Devices and Integrated Circuits - 801 Chemistry - 802.3 Chemical Operations - 804.1 Organic Compounds - 951 Materials Science - 804.2 Inorganic Compounds - 821.0 Woodlands and Forestry - 821.5 Agricultural Wastes - 933.1.2 Crystal Growth - 805.1.1 Biochemical Engineering - 712.1 Semiconducting Materials - 525.1 Energy Resources and Renewable Energy Issues - 442.2 Land Reclamation - 452.3 Industrial Wastes - 454.2 Environmental Impact and Protection - 454.3 Ecology and Ecosystems - 461.2 Biological Materials and Tissue Engineering - 461.7 Health Care - 481.1 Geology - 483.1 Soils and Soil MechanicsDOI:10.1007/s10750-008-9649-9

temporal resolution, the present study firstly introduced a new method based on fluorescence correlation spectroscopy (FCS). FCS is a kind of single-molecule technique with high temporal and spatial resolution to analyze the dynamics of fluorescent molecules in nanomolar concentration. Through a time correlation analysis of spontaneous intensity fluctuations, this technique in conjunction with EGFP as a probe is capable of determining nucleoplasmic viscosity in terms of Stokes-Einstein equation as well as its corresponding analysis of the diffusion coefficient for EGFP in the nucleus. The results showed that nucleoplasmic viscosity of ASTC-a-1 cells and HeLa cells were respectively (2.55&plusmn;0.61) cP and (2.04&plusmn;0.49) cP at pH 7.4 and 37 &deg;C, consistent with the results by traditional methods, and nucleoplasmic viscosity was found to be larger than cytoplasmic viscosity. Meanwhile, the real-time analysis of nucleoplasmic viscosity in living cells exposed to hypotonic media proved that FCS could be used to track the changing rheological characteristics of the nucleoplasm in living cells. Taken together, this study suggests that FCS provides an accurate and non-invasive method to investigate the microenvironment in living cells on the femtoliter scale and it can be used as a powerful tool in researches on the dynamical processes of intracellular molecules.Number of references:20Main heading:ViscosityControlled terms:Correlation methods - Cytology - Enzyme activity - Fluorescence - Fluorescence spectroscopy - Hydrodynamics - Molecular spectroscopy - Molecules - Spectrum analysis - ViscometersUncontrolled terms:Cytoplasm - Diffusion Coefficients - Dynamical process - Fluorescence correlation spectroscopy (FCS) - Fluorescent molecules - Hela cells - Intensity fluctuations - Living cells - Microenvironment - Nanomolar concentrations - Non-invasive methods - Nucleoplasm - Real time - Real-time analysis - Rheological characteristics - Single-molecule techniques - Spatial resolutions - Stokes-Einstein equations - Temporal resolutions - Time correlationsClassification code:944 Moisture, Pressure and Temperature, and Radiation Measuring Instruments - 931.2 Physical Properties of Gases, Liquids and Solids - 931.3 Atomic and Molecular Physics - 941 Acoustical and Optical Measuring Instruments - 941.3 Optical Instruments - 941.4 Optical Variables Measurements - 942 Electric and Electronic Measuring Instruments - 943 Mechanical and Miscellaneous Measuring Instruments - 943.3 Special Purpose Instruments - 922.2 Mathematical Statistics - 461.2 Biological Materials and Tissue Engineering - 461.9 Biology - 631.1 Fluid Flow, General - 921 Mathematics - 631.1.1 Liquid Dynamics - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 631.2 HydrodynamicsDOI:10.3964/j.issn.1000-0593(2009)02-0459-04Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:Well-dispersed superparamagnetic nanocomposites, mesoporous silica-coated nano-sized magnetite (MSNSM) as a magnetic carrier and CuO-coated MSNSM (CuO-MSNSM) as a new desulfurizer have been reported. The MSNSM, prepared via a nano-assembling method by using cationic surfactants as templates, consists of a 12-nm-in-diameter core of magnetite particle and about 4-nm-thickness shell of mesoporous silica (MS), and shows high specific surface area (ca. 154 m²/g). The CuO-MSNSM was obtained by immersing the MSNSM into a copper solution, which formed a nano-scaled particle of CuO onto the surface of MSNSM upon followed calcination. The results revealed that both MSNSM and CuO-MSNSM exhibit strongly superparamagnetic properties with saturation magnetization values (M<inf>s</inf>) of over 28 emu/g. Both would be potential functional magnetic carriers. As an example of its wide applications, the CuO-MSNSM was tested as a desulfurizer. It was found that the CuO-MSNSM is an excellent organic sulfur adsorber, performing fully separation of the organic sulfur in a model dodecanethiol-added petroleum liquid. &copy; 2008 Elsevier Inc.

Box 3337, Columbus, OH 43210-3337, United StatesAbstract:The broad-spectrum expression of telomerase in most malignancies makes it a promising target for a cancer diagnostic and prognostic tool. Conventional polymerase chain reaction (PCR)-based telomerase activity assay is highly sensitive but susceptible to amplification-related errors. Here, we present a novel approach to telomerase activity detection. The detection of telomerase activity is accomplished by the hybridization of electrochemiluminescence (ECL) nanoprobes to telomerase reaction products, subsequent capture by magnetic beads, and in situ measurement of the light signal from ECL nanoprobes. The ECL intensity directly reflects the quantity of telomerase reaction products, thus telomerase activity. The high sensitivity afforded by the current magnetic bead and nanoparticle based ECL detection platform allows measuring of telomerase activity from as little as 500 cultured cancer cells in crude cell extracts without the PCR amplification of telomerase reaction products. In addition, a comparative study of the ECL nanoprobe and linear telomere antisense ECL probe was executed. By the employment of the ECL nanoprobe, a gain of about 100-fold elevation of sensitivity was determined. The method described here is ideal for telomerase activity analysis due to its reliability and high sensitivity.

Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United StatesAbstract:An optical transpose interconnection system (OTIS) network with n² nodes is a two-level swapped architecture built of n copies of an n-node basis network that constitute its clusters. A simple rule for intercluster connectivity (node j in cluster i connected to node i in cluster j, for all i &ne; j) leads to regularity, modularity, packageability, fault tolerance, and algorithmic efficiency of the resulting networks. We prove that an OTIS (swapped) network with a connected basis network possesses maximal fault tolerance, regardless of whether its basis network is maximally fault tolerant. We also show how the corresponding maximal number of node-disjoint paths between two nodes of a swapped network can be algorithmically constructed in a manner that is independent of the existence and construction of node-disjoint paths within its basis network. Our results are stronger than previously published results and they replace a number of proofs and constructions in the literature for specific basis networks. Additionally, we use our parallel path constructions to establish that the fault diameter and wide diameter of an OTIS network is no more than 4 units greater than its diameter. &copy; 2009 IEEE.Number of references:18Main heading:Quality assuranceControlled terms:Errors - Fault tolerance - Interconnection networks - ReliabilityUncontrolled terms:Connectivity - Fault diameter - Interconnection network - Maximal fault tolerance - Node-disjoint paths - OTIS network - Parallel paths - Robustness - Swapped network - Topological properties - Wide diameterClassification code:921 Mathematics - 913.3 Quality Assurance and Control - 731 Automatic Control Principles and Applications - 922.2 Mathematical Statistics - 722.4 Digital Computers and

The system for biomedical diagnostics was designed with four parts consisting of an irradiating source, digital B-mode ultrasound diagnostic equipment with a liner transducer array, data acquisition and transmission system, and rotation devices for imaging scanning. Multielement phase-controlled focus technique was applied to reduce the data-acquisition time and enhance signal-to-noise ratio. Under the self-designed working sequence, data-acquisition time of an image can be reduced to 12 s. A series of experiments were performed to estimate the imaging quality of the system. The lateral and elevational resolutions of the system were detected to be 0.25 and 1.4 mm, respectively. The results show that the system has the feasibility to be used as a medical imaging method, and it may provide a new rapid and noninvasive imaging modality for clinical applications. &copy; 2009 American Institute of Physics.Number of references:18Main heading:Ultrasonic imagingControlled terms:Acoustic waves - Data communication equipment - Diagnostic radiography - Digital devices - Digital image storage - Electric power transmission - Imaging systems - Medical imaging - Mergers and acquisitions - Optoelectronic devices - Photoacoustic effect - Signal to noise ratio - Time series - Tomography - Ultrasonic applications - UltrasonicsUncontrolled terms:Acquisition time - Bio medical diagnostics - Biomedical imaging - Clinical applications - Diagnostic equipments - Imaging methods - Imaging qualities - Multi elements - Non-invasive imaging - Photoacoustic tomographies - Signal-to-noise ratios - System-based - Transducer arrays - Transmission systems - Ultrasound diagnosisClassification code:723.2 Data Processing and Image Processing - 723.5 Computer Applications - 741 Light, Optics and Optical Devices - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 722.4 Digital Computers and Systems - 746 Imaging Techniques - 753.1 Ultrasonic Waves - 753.3 Ultrasonic Applications - 912 Industrial Engineering and Management - 931.2 Physical Properties of Gases, Liquids and Solids - 751.1 Acoustic Waves - 722.3 Data Communication, Equipment and Techniques - 461.7 Health Care - 706.1.1 Electric Power Transmission - 713.5 Other Electronic Circuits - 714.2 Semiconductor Devices and Integrated Circuits - 716 Telecommunication; Radar, Radio and Television - 461.1 Biomedical Engineering - 716.1

There is great need for enhancement of imaging ability to tumor tissues. Optical coherence tomography (OCT) is used in detection and location of varied tumor tissues. In order to improve the sensitivity and specificity of an OCT image, hematoporphyrin as a new type of contrast agent was used in this study. The orthotopic graft model of gastric cancer in nude mice was used. The image formations of the tumor tissues without and with injection of hematoporphyrin in vivo were obtained by an OCT system at a 1310 nm central wavelength. The experimental results showed that the tumor tissues accumulated with hematoporphyrin have an ability of light absorption which results in the increase of signal attenuation in the gastric cancer tissues, and that the boundary between the tumor tissues and surrounding normal tissues was perfectly defined owing to the accumulation of

hematoporphyrin. From the experimental results, it is found that hematoporphyrin, a photosensitizing agent, could be used as a contrast agent for OCT imaging of tumor tissues, which offer an effective OCT image method for clinical detection and localization of tumor tissues in vivo. &copy; 2008 Institute of Physics and Engineering in Medicine.Number of references:21Main heading:HistologyControlled terms:Coherent light - Diagnostic radiography - Experiments - Medical imaging - Porphyrins - Signal processing - Tissue - Tomography - TumorsUncontrolled terms:Central wavelengths - Clinical detections - Contrast agents - Diagnostic systems - Early developments - Gastric cancers - HematoPorphyrin - Image formations - In-vivo - Malignant diseases - Normal tissues - Nude mouse - OCT images - OCT imaging - Optical Coherence tomographies - Optical coherences - Orthotopic - Photosensitizing agents - Potential abilities - Sensitivity and specificities - Signal attenuations - Tomographic images - Tumor tissuesClassification code:931.2 Physical Properties of Gases, Liquids and Solids - 901.3 Engineering Research - 804.1 Organic Compounds - 746 Imaging Techniques - 741.1 Light/Optics - 741 Light, Optics and Optical Devices - 723.5 Computer Applications - 723.2 Data Processing and Image Processing - 716.1 Information Theory and Signal Processing - 461.9 Biology - 461.7 Health Care - 461.2 Biological Materials and Tissue Engineering - 461.1 Biomedical EngineeringDOI:10.1088/0031-9155/53/23/008Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 3929, Beijing, 100854, ChinaAbstract:Because statistical monitoring model based on multi-way principal component analysis was strongly affected by outlying observations, a method of extracting outliers from the modeling historical database, based on modified scaling CDC/MVT (Closest Distance to Center/ellipsoidal Multivariate Trimming) was proposed. The CDC was incorporated with MVT in the proposed

algorithm. Firstly, the algorithm utilized the modified scale to obtain the mean and standard deviation of the off-line modeling normal data, and carried out centering and standardization for the modeling data using the mean and standard deviation. Secondly, the most consistent half observations were extracted from the modeling historical database by the algorithm of CDC. Finally, these observations were then used to initialize the mean and covariance of Mahalanobis distance, and the other observations were gotten by the iterative calculation of Mahalanobis distance. This proposed algorithm was applied to extract outliers from &beta;-mannanase fermentation batch process and compared with the other robust outlier detection algorithms. The application results show that the proposed algorithm could effectively extract the outliers from the modeling historical database.Number of references:10Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The simulated results show that at the same flow-rate and with the same numbers of total tower plates, the two modified processes consume much less energy than the existing conventional series, of which the heat-integrated one has the best energy-saving effect. The double-effect distillation arrangement can save energy by 31.9%, and the heat-integrated process can reach 35.8% compared with the conventional arrangement.

The results showed that the extracts of red rose flowers had obviously stronger antioxidant activity when compared to other flowers. Polyphenolic content had significant relationships with the 1,1-diphenyl-2-picrylhydrazyl (DPPH) (r = 0.983, P less than or equal 0.01) and superoxide free radical scavenging activity (FRSA) (r = 0.588, P less than or equal 0.01), but no significant relationship with hydroxyl FRSA (r = 0.184, P &gt; 0.05) in tested open flowers. However, in tested flower buds, polyphenolic content was correlated well with the DPPH FRSA (r = 0.993, P less than or equal 0.01), superoxide FRSA (r = 0.738, P less than or equal 0.01), and hydroxyl FRSA (r = 0.737, P less than or equal 0.01), respectively.

Box 80, Xi'an, 710068, ChinaAbstract:Self-similar pulse propagation properties in Yb⁺³-doped fiber amplifiers with the effects of higher-order dispersion and gain dispersion were studied. The effects of initial pulse energy, third-order dispersion and the doped ions dipole relaxation time on the pulse propagation quality were relatively expounded with the analytical and simulative methods. It is shown that with nonlinear area of parabolic pulses being enlarged, the center of chirp moves forward or backward, due to the difference of third-order dispersion coefficient. And the figure of pulses is distorted with the pulse peak delaying to one side and the center location excursing. Gain dispersion can be a filter, which can properly compress pulse-width. Results proved the possibility of the self-similar pulse existing in gain medium with a certain relaxation time.Number of references:12Main heading:Fiber amplifiersControlled terms:Dispersion (waves) - Electromagnetic dispersion - Fiber lasers - Nonlinear optics - Relaxation processes - Ternary systems - YtterbiumUncontrolled terms:Dipole relaxations - Gain dispersion - Gain dispersions - Gain mediums - Order dispersions - Parabolic pulses - Propagation properties - Pulse energies - Pulse propagations - Self-similar - Self-similar pulse - Third-order dispersionClassification code:744.4 Solid State Lasers - 741.1.2 Fiber Optics - 741.1.1 Nonlinear Optics - 931.1 Mechanics - 711.1 Electromagnetic Waves in Different Media - 531.2 Metallography - 531.1 Metallurgy - 547.2 Rare Earth MetalsDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

IR spectra, elemental analysis, HNMR spectra and MS were used to determine its structure. Meanwhile, the spectra characters of MQBC and the fluorescent behaviors of the complex with zinc (II) and copper (II) were investigated, and the results showed that the lower rim oxygen atoms in calix [4] arenes may act as electrons donor to metal ions. Calix [4] arene was chosen as a basic skeleton of a photoresponsive ion carrier because its quinoline derivatives are known to emit fluorescence and absorb UV in the solution, and the information of the complex with metal ions will be known by spectra experiment. The UV absorbance became weak at the band of 226 nm but was enhanced at the band of 315 nm when it bound zinc ions, The complex constant (K) and binding ratio (x) were determined to be 2064 L&middotmol^-1 and 1, respectively, by UV spectra experiment It is expected that MQBC will be applied to the detection of trace zinc ions. The fluorescence spectra experiment found that MQBC is has feeble fluorescence attributed to the intramolecular photoinduced electron transfer (PET) between oxygen atoms and methylquinoline groups. When MQBC was combined with zinc (II) and copper (II), it caused the inhibiting photoinduced electron transfer process between oxygen atoms and methylquinoline groups leading to the enhancement of fluorescence. In addition, the photoinduced electron mechanism was discussed and the influence of the concentration of zinc (II) and copper (II) on the fluorescence intensities was studied.Number of references:12Main heading:DerivativesControlled terms:Atoms - Chemical analysis - Copper - Fluorescence - Infrared spectroscopy - Metal ions - Nuclear magnetic resonance spectroscopy - Oxygen - Synthesis (chemical) - ZincUncontrolled terms:Binding ratio - Calix [4] arene derivative - Complex constant - Electrons

The ASTC-a-1 cells expressing stably with SCAT3, a fluorescence resonance energy transfer (FRET) plasmid based on the green fluorescent protein mutants (GFPs), was verified using confocal fluorescence scanning microscopy imaging, fluorescence emission spectra and FRET acceptor photobleaching techniques. The caspase-3 activation can be monitored by the fluorescence emission spectra of SCAT3 inside living cells. The cells expressing stably with SCAT3 were cultured with XAP for 96

hours, and the fluorescence emission spectra of the SCAT3 inside living cells were measured at the time of 0, 24, 72, and 96 hours, respectively. Experimental results showed that: (1) XAP inhibited obviously the proliferation of ASTC-a-1 cells and induced the cell death. The inhibition of XAP on the cells was dose-dependent; (2) the SCAT3 inside living cells was cleaved completely 72 hours after the XAP treatment, implying that a great deal of pro-caspase-3 was activated by XAP; (3) 24 hours after XAP treatment, the emission spectra of SCAT3 inside living cells cultured in DMEM without XAP for 48 and 72 hours did not change greatly, implying that XAP did not activate obviously caspase-3 within 24 hours.Number of references:20Main heading:Emission spectroscopyControlled terms:Activation analysis - Activation energy - Biological organs - Cell death - Cells - Energy storage - Energy transfer - Fluorescence - Health - Imaging techniques - Light emission - Luminescence - PhotobleachingUncontrolled terms:Acceptor photobleaching - Caspase 3 - Caspase 3 activation - Confocal fluorescence scanning microscopy - Dose dependent - Emission spectrums - Fluorescence emission analysis (FEA) - Fluorescence emission spectrum - Fluorescence resonance energy transfer (FRETS) - Green Fluorescent Protein (GFP) - Human lung adenocarcinoma cells - Human lungs - Inhibition effects - Living cellsClassification code:801.4 Physical Chemistry - 801 Chemistry - 746 Imaging Techniques - 741.1 Light/Optics - 525.7 Energy Storage - 525.4 Energy Losses (industrial and residential) - 461.9 Biology - 461.6 Medicine and Pharmacology - 461.2 Biological Materials and Tissue EngineeringDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

In this paper, a new principle biosensor for non-invasive detection of seed vigor based on quantitative measurement of superoxide via selective probe 2-methyl-6-(p-methoxyphenyl)-3,7-dihydroimidazo [1,2&alpha;] pyrazin-3-one (MCLA)-mediated chemiluminescence (CL) was developed. The biosensor, which used a compact single-photon counting module (SPCM) to collect the CL signal, could evaluate seed vigor in vivo. Benefiting from the high CL efficiency of MCLA reacting with superoxide and high sensitivity of the SPCM technique, the trace superoxide generated by dry seeds under storage state can be detected to achieve rapid and non-invasive determination of the seed vigor. In comparison with the traditional methods for fast measuring seed vigor based on measurement of physiological and biochemical properties, our proposed technique has significant advantages such as low cost, simplicity, convenient operation and short time consuming. To demonstrate the utility of the system, it was applied to evaluate MCLA-mediated CL of three different plant species wheat (Ze Yu No. 2), maize (Tai Gu No. 1 and 2) and rice (Jing Dao No. 21) seeds with different degrees of aging. The experimental results suggested that there was an excellent positive correlation between the seed vigor assessment from quantitative TTC-test and the detection based on MCLA-mediated CL of superoxide

measurement. The new principle of seed vigor measurement is a challenge and breakthrough to conventional method of seed vigor determination and may be a potential technique of the next generation seed vigor detection. &copy; 2008 Elsevier B.V.

The coordination geometry around Ln(III) ions in the complexes 1 and 2 was a distorted tricapped trigonal prism with a nine coordination. In the crystal, the molecular organization was further stabilized by well-defined weak hydrogen bonding interactions between the neutral dinuclear molecular units that led to the formation of a three-dimensional network. The fluorescence properties of the two complexes 1 and 2 in organic solvents were also studied.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Basic experiments for quantum information have demonstrated the important role that photons play in future practical quantum information system. Technical prospects of processing quantum information in quantum computing, quantum communication and quantum cryptography encourage researchers to develop advanced photonic devices with high precision. We recognized that the most essential is to develop component parts of every kind that can constitute a qualified quantum information system. By using these component parts with high precision, it is possible to decrease errors in a practical quantum information system. The errors come from interaction of quantum information with environment that appear as decoherence. In terms of the technical terminology, this kind of interaction is appeared in conventional characterization as loss of the devices that are responsible for the permutation between quantum information system and environment noise. Therefore we analyze several possible structures of the components and devices that should be considered in the design of the components and the devices for quantum information usage. The emitters should generate quantum eigen state that the quantum dot with specified shape is embedded in mode matched waveguide. The quantum bits should be encoded only by phase modulation without loss. The receiver should also be sensitive to the quantum state. Every step of the efforts challenges the quantum limitation and the technologies available.Number of references:40Main heading:Quantum computersControlled terms:Bit error rate - Eigenvalues and eigenfunctions - Information systems - Photonics - Quantum cryptography - Semiconductor quantum dots - WaveguidesUncontrolled terms:Bose statistics - Quantum information - Quantum information systems - Quantum limitationClassification code:903.2 Information Dissemination - 741.1 Light/Optics - 723.1 Computer Programming - 921.1 Algebra - 722 Computer Systems and Equipment - 714.3 Waveguides - 714.2 Semiconductor Devices and Integrated Circuits - 716 Telecommunication; Radar, Radio and TelevisionTreatment:Theoretical (THR)DOI:10.1117/12.756908Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The composition, phase structure, mechanical performance, and oxidation-resistance of the nitride coatings were investigated by scanning electron microscopy (SEM), atomic force microscope (AFM), X-ray diffraction (XRD), auger electron spectroscopy (AES), and X-ray photoelectron microscopy (XPS). A new process for preparing protective coatings of the titanium alloy is successfully acquired. The experimental results indicate that the added element chromium in the TiAlN coatings make a contribution to form the (220) preferred direction. The phases of the coatings are composed of (Ti, Al) N and (Ti, Cr)N. After 700&deg;C and 800&deg;C oxidation, AES analysis shows that the diffusion distribution of the TiAlCrN coatings emerges a step shape. From the outside to the inner, the concentrations of O, Al, and Cr reduce, but those of Ti and N increase. The Al-rich oxide is formed on the surface of the coatings, and the mixed structure of Ti-rich and Cr-rich oxides is formed in the internal layer. The oxidation resistance of the TiAlCrN coatings is excellent at the range of 700 to 800&deg;C. Adhesion wear is the dominant mechanical characteristic for the titanium alloy at room temperature, and the protective coatings with high hardness can improve the mechanical properties of the titanium alloy. The wear resistance of the TC11 alloy is considerably improved by the TiAlCrN coatings. &copy; 2008 The Nonferrous Metals Society of China.Number of references:8Main heading:Titanium alloysControlled terms:Alloys - Aluminum - Atomic force microscopy - Atomic spectroscopy - Auger electron spectroscopy - Cavity resonators - Chemical oxygen demand - Chromate coatings -

The goal of this technique is to find intuitive basis such that training examples can be faithfully reconstructed using linear combination of basis images which are restricted to non-negative values. Thus, NMF basis images can be understood as localized features that correspond better with intuitive notions of parts of images. However, there has been few systematic study to explore various methods for initialization of NMF algorithm, which is crucial for the performance of NMF algorithm in data analysis. In this paper, we discuss a structured NMF initialization scheme based on the clustering method. Comparing with the random initialization in common use, our method achieved faster convergence while maintaining the data structure and also obtained good result for the face recognition task. Furthermore, we also proposed to use a normalized AIC incorporated with our NMF initialization for rank selection of traditional NMF at the cost of much less computational load while obtaining a good performance in face recognition. &copy; 2008 Elsevier Inc.

With the aid of the Ehrenfest theorem in quantum mechanics, we obtain an equation of motion for the soliton center, and find its analytical solution. Comparison with numerical simulations shows that our analytical solution can describe the motion of the soliton center very well when the optical lattice period is much larger than the soliton width. It is found that there exists a critical angle that is a function of the optical lattice parameters. When its incident angle is smaller than the critical angle, the soliton is trapped within the waveguide induced by the optical lattices. Above the critical angle, the soliton leaves the central waveguide and propagates along its original direction traveling across the optical lattices. A way to control the soliton mobility is discussed based on the finding. &copy; 2008 The American Physical Society.Number of references:28Main heading:SolitonsControlled terms:Computer simulation - Crystal lattices - Equations of motion - Function evaluation - Optical materials - Quantum theory - WaveguidesUncontrolled terms:(Hi-Bi) waveguide - American Physical Society (APS) - Analytical solutions - Critical angles - Ehrenfest theorem - Equation of motion - Incident angles - Non local - Numerical simulations - Optical lattices - Optical lattices (OL) - Quantum mechanics (QM) - soliton mobility - Spatial optical solitonsClassification code:931.4 Quantum Theory; Quantum Mechanics - 921.6 Numerical Methods - 921.2 Calculus - 933.1.1 Crystal Lattice - 921.1 Algebra - 723.5 Computer Applications - 714.3 Waveguides - 741.3 Optical Devices and Systems

Box 80, Xi'an, 710068, ChinaAbstract:A quasi-distributed fiber Bragg grating (FBG) sensor based on arrayed waveguide grating (AWG) is researched in theory and experiment. This sensor system has the advantages of easy operation, high response speed, low cost and high resolution. Its interrogating technique is based on the double-channel intensity-demodulating and the demultiplexing of an arrayed waveguide grating. The experimental result shows that the wavelength and temperature interrogation of the system have high linearity for the wide bandwidth of FBG, and the wavelength and temperature measurement accuracy reaches 2 pm and 0.2&deg;C under the effects of system stability and FBG crosstalk.Number of references:16Main heading:Fiber optic sensorsControlled terms:Arrayed waveguide gratings - Demodulation - Demultiplexing - Fiber Bragg gratings - Fiber optic components - Fibers - Optical waveguides - Sensors - System stability - Temperature measurement - WaveguidesUncontrolled terms:Arrayed waveguide grating - Arrayed waveguides - Fiber bragg grating sensors - High linearities - High resolutions - High response speeds - Intensity demodulation - Low costs - Sensor systems - Wide bandwidthsClassification code:741.1.2 Fiber Optics - 741.3 Optical Devices and Systems - 801 Chemistry -

Eng. Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United StatesAbstract:Ten cities with different urban sizes located in the Pearl River Delta, Guangdong Province, China were selected to study the relationships between surface urban heat island (S-UHI) intensity and land use/cover factors like urban size, development area, water proportion and mean NDVI, etc. All the cities are almost at the same latitude, show similar climate and have the same solar radiation, the influence of which shall be eliminated during our computation and comparative study. A variance-segmenting method was proposed to compute the S-UHI intensity for each city from the retrieved land surface temperature (LST). Factors like urban size, development area and water proportion were extracted directly from the classification images of

the same ETM+ data. The urban mean NDVI value was used to quantify the urban vegetation abundance. Regression and correlation analyses were performed to study the relationships between the S-UHI intensity and these land use/cover factors, and the results show that S-UHI intensity is highly correlated to urban size (r=0.83) and development area (r=0.74). It was also proved that negative correlations existed between S-UHI intensity and urban mean NDVI (r=-0.62), and water proportion (r=-0.54). Linear and logarithm functions between S-UHI intensity and land use/cover factors were established respectively. &copy; 2008 IEEE.Number of references:23Main heading:LandformsControlled terms:Agglomeration - Atmospheric temperature - Extraction - Heat flux - Image processing - Observatories - Remote sensing - Sun - Technical presentations - VegetationUncontrolled terms:Classification images - Comparative studies - Correlation analyses - Guangdong provinces - Land surface temperatures - Land use/cover - Landsats - Logarithm functions - Negative correlations - Pearl river deltas - Urban heat islands - Urban vegetation abundancesClassification code:657.2 Extraterrestrial Physics and Stellar Phenomena - 723.2 Data Processing and Image Processing - 731.1 Control Systems - 903.2 Information Dissemination - 741 Light, Optics and Optical Devices - 821 Agricultural Equipment and Methods; Vegetation and Pest Control - 901.2 Education - 802.3 Chemical Operations - 657 Space Physics - 641.2 Heat Transfer - 402.1 Industrial and Agricultural Buildings - 443 Meteorology - 443.1 Atmospheric Properties - 461.9 Biology - 481.1 Geology - 525.1 Energy Resources and Renewable Energy IssuesDOI:10.1109/EORSA.2008.4620344Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The following are the main results of this paper. 1. Two free boundaries are monotonic and infinitely differentiable. 2. The optimal exercise boundary of American put option with regime-switching volatility in the bearish (or bullish) market is smaller (or higher) than the one of standard American put option. And the price of American put option with regime-switching volatility in the bearish (or bullish) market is higher (or smaller) than the one of standard American put option. 3.

The parameters (including the concentration of organic solvent in the mobile phase, pH of the electrolyte buffer, applied voltage) affecting the separation resolution were evaluated. Two on-line concentration techniques, namely, solvent gradient zone sharpening effect and field-enhanced sample stacking, were utilized to improve detection sensitivity. The combination of the two techniques proved to be beneficial to enhance the detection sensitivity by enabling the injection of large volumes of samples. Compared to the conventional injection mode, the enhancement in the detection sensitivities of phytohormones using the on-line concentration technique is in the range from 9- to 23-fold. The developed pCEC method was applied to evaluate phytohormones in corns. &copy; 2008 Wiley-VCH Verlag GmbH &amp; Co.

The photo- and electro-luminescent properties of these polymers were investigated. Efficient energy transfer from the Cz segment to the DHTBT unit occurs even if the DHTBT content as low as 1 mol%. PL emission was red-shifted significantly from 645 nm to 700 nm with the increase in DHTBT content by 150 mol%. PL efficiencies decreased with the increase in DHTBT content in the polymers from 55% for PCzDHTBT1 gradually down to 7% for PCzDHTBT50. EL emission of these polymers red-shifted from 640 nm to 690 nm when the DHTBT content increased from 1 mol% to 50 mol%. The highest external quantum efficiency was 1.67% for PCzDHTBT25 with the maximum luminescence of 870 cd/m² in the device configuration of ITO/PEDOT:PSS/polymer/PFN/Ba/Al. The enhancement of device performances could be due to the improved electron injection by inserting the amino-containing polyfluorene (PFN) layer. These polymers are promising candidates as a red emitter in the full-color polymer light emitting diodes (PLEDs). &copy; 2008 World Scientific Publishing Company.Number of references:36Main heading:Conjugated polymersControlled terms:Copolymers - Derivatives - Light emission - Polycondensation - ThiopheneUncontrolled terms:2,7-Carbazole - Red light emitting polymers - Thiophene derivativesClassification code:741.1 Light/Optics - 804.1 Organic Compounds - 815.1.1 Organic Polymers -

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:The effect of growth rate in the early stage of high temperature (HT) GaN layer growth on the quality of GaN by MOCVD has been investigated. The properties of GaN layers were measured by double crystal X-ray diffraction (DCXRD), Hall method, photoluminescence, and atomic force microscopy, respectively. The results reveal that the quality of GaN layers is influenced by the growth rate of HT GaN growth in the early stage. The properties of GaN layers are obviously improved by decreasing the growth rate in the early stage of HT GaN growth properly. However, when the growth rate decreases to some extent, the quality of GaN layer deteriorates instead. The reasons behind this phenomenon were discussed. &copy; 2008 Elsevier B.V.

Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United StatesAbstract:Neural networks (NNs) have been widely used to predict financial distress because of their excellent performances of treating non-linear data with self-learning capability. However, common neural networks often suffer from long convergent processes and occasionally involve in a local optimal solution that more or less limited their applications in practice. To overcome the

drawbacks of neural networks, this study develops a new modified genetic algorithm - multi-population adaptive genetic back-propagation algorithm (MAGBPA). In this paper, a hybrid system combining feed-forward neural network and MAGBPA -multi-population adaptive genetic back-propagation neural network (MAGBPNN) is proposed to overcome NN's drawbacks. Furthermore, the new model has been applied to financial distress analysis based on the data collected from a set of Chinese listed corporations, and the results indicate that the performance of MAGBPNN model is much better than the ones of common neural network model. &copy; 2008 IEEE.Number of references:6Main heading:Neural networksControlled terms:Adaptive algorithms - Backpropagation - Diesel engines - Evolutionary algorithms - Feedforward neural networks - Genetic algorithms - Image classification - Ketones - Population statistics - VegetationUncontrolled terms:Back-propagation algorithms - Back-Propagation neural networks - BP neural networks - Excellent performances - Financial distresses - Hybrid systems - Learning capabilities - Local optimal solutions - Modified genetic algorithms - Neural network models - New modelsClassification code:921 Mathematics - 821 Agricultural Equipment and Methods; Vegetation and Pest Control - 804.1 Organic Compounds - 723.5 Computer Applications - 723.4 Artificial Intelligence - 922.2 Mathematical Statistics - 723 Computer Software, Data Handling and Applications - 612.2 Diesel Engines - 525.1 Energy Resources and Renewable Energy Issues - 461.9 Biology - 461.1 Biomedical Engineering - 716 Telecommunication; Radar, Radio and TelevisionDOI:10.1109/WGEC.2008.46Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The nonlinear finite-difference time-domain method is applied to conducting numerical experiments. The first lattice acts as the deflecting stage, in which beams with different power densities are separated from each other spatially. The second lattice has a function of "angular amplifier" that enlarges the separation angle between two power density ranges (lower than 100 W/&mu;m² and higher than 300 W/&mu;m ²) to 90&deg; -like. In the first photonic band, due to the local change of refractive indices induced by the pumping power, new interfaces are formed between the pumped and nonpumped areas. The k-vector will be rotated by these interfaces until the phase velocity and group velocity have the same direction. The shape of the interface between these two stages is discussed. &copy; 2008 Optical Society of America.Number of references:17Main heading:Phase interfacesControlled terms:Kerr magnetooptical effect - Magnetic field effects - Magnetooptical effects - Method of moments - Optical properties - Photonics - Prisms - Refractive index - Time domain analysisUncontrolled terms:Background mediums - Change of refractive indices - Finite-difference time-domain methods - Group velocities - Kerr effects - Numerical experiments - Photonic bands - Photonic lattices - Power densities - Power splitters - Pumping powers - Separation angles - Superprism effects - Two stagesClassification code:931.2 Physical Properties of Gases, Liquids and Solids - 921 Mathematics - 801.4 Physical Chemistry - 744 Lasers - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 731.1 Control Systems - 717 Optical Communication - 712 Electronic and Thermionic Materials - 703.1.1 Electric Network Analysis - 701.2 Magnetism: Basic Concepts and PhenomenaDOI:10.1364/AO.47.004701Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Abstract:AflatoxinB1 was extracted from rice contaminated artificially with Aspergillus flavus by using methanol-water (50:50 v/v). As for experiment group, sodium chloride was added into the extracted solution of AfBl, the excitation wavelength of 365 nm under the fluorescence mode, and the emission spectrum peak at 440nm were observed. To study the detoxification of AflatoxinB 1 in several alkaline solutions, the solution of alkaline with difference concentration was added into the solution of AfB1 respectively. The results showed that all of three alkaline solutions could decrease the 440nm emission spectrum peak of solution of AfBI in varying degrees, the effect to decrease emission spectrum peak of AfBl was very obvious in sodium hypochlorite (NaClO), and sodium hydroxide (NaOH) took second place, whereas in ammonia (NH<inf>3</inf>.H <inf>2</inf>O), the effect was the weakest among three alkaline solutions. Moreover, the effects were different in the same alkaline solutions with different concentration, as hydrochloric acid (HCl) in low concentration was added to this complex AfB1 alkaline solutions, detoxification efficacy of AfB1 were found to be obviously increased. It was concluded that the detoxification of AflatoxinB1 may be affected by alkaline solutions according to their concentration and be degraded greatly by acid addition.Number of references:16Main heading:Grain (agricultural product)Controlled terms:Ammonia - Detoxification - Emission spectroscopy - Fluorescence spectroscopy - Hydrochloric acid - Methanol - Sodium compoundsUncontrolled terms:Alkaline solutions - Aspergillus flavus - Chemical detoxification - Emission spectrum peakClassification code:941.3 Optical Instruments - 821.4 Agricultural Products - 804.2 Inorganic Compounds - 941.4 Optical Variables Measurements - 804.1 Organic Compounds - 741.1 Light/Optics - 445.1 Water Treatment Techniques - 741.3 Optical Devices and SystemsTreatment:Theoretical (THR); Experimental (EXP)Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Focused Gaussian beams with well-defined waists and Rayleigh lengths necessary for Z-scan experiments are generated through a conjugated manipulation of the Gaussian beams propagating in free space. The Z-scan measurements used for bulk materials are naturally extended to 1D PCs after incorporating the frequency- and power-density-dependent reflections into their linear and nonlinear absorptions. The closed- and open-aperture Z-scan traces for the 1D PCs are obtained and a symmetric method is employed to modify the asymmetric closed-aperture traces. The nonlinearity enhancement factors at different frequencies in the first and second bands are derived numerically and analytically. A good agreement is found between the numerical and analytical results in the case of weak nonlinearity. Moreover, the dependences of the enhancement factor on the incident power density for different frequencies in the 1D PCs are extracted and they are found to be much different from those in bulk materials. It is revealed that the variation of the group velocity with increasing power density is responsible for the power-density dependence of the enhancement factor. It indicates that in practice one must deliberately choose the working frequency and power density of PC-based devices in order to achieve a maximum enhancement of nonlinearity. &copy; 2008 Optical Society of America.Number of references:28Main heading:Photonic crystalsControlled terms:Crystal atomic structure - Crystallography - Crystals - Electromagnetic field theory - Electromagnetic fields - Electromagnetism - Experiments - Extraction - Finite difference time domain method - Gaussian beams - Gaussian noise (electronic) - Magnetism - Materials handling equipment - Microcomputers - Ontology - Photonics - Powders - Time domain analysis - Trellis codesUncontrolled terms:Analytical results - Bulk materials - Density-dependence - Density-dependent - Different frequencies - Enhancement factors - Finite difference time domain techniques - Free spaces - Group velocities - Incident power - Kerr non-linearity - Non linearities - Non-linear absorption - Non-linearity enhancement - One-dimensional photonic crystals - Open-aperture Z-scan - PC-based - Power densities - Rayleigh lengths - Weak non-linearity - Working frequencies - Z-scan measurementsClassification code:723.2 Data Processing and Image Processing - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 933.1 Crystalline Solids - 802.3 Chemical Operations - 921 Mathematics - 931.3 Atomic and Molecular Physics - 901.3 Engineering Research - 723 Computer

The measurement was performed in the model of rats suffering with Spleen-Stomach Dampness-Heat Syndrome using OCT equipment, OCT image and histology estimates of the glossal layer of microstructure were obtained, and the accurate thickness and moisture degree of the tongue coating were analyzed. These OCT image showed that tongue every layer matched the histology estimates of the glossal microstructure, and compared with normal control group the thickness of tongue

coating increased in rats suffering with Spleen-Stomach Dampness-Heat Syndrome than normal control rats (P&lt;0.01), yet the moisture degree of tongue body of model group decreased (P&lt;0.01). Therefore, OCT image technique may be benefit and helpful as a tool to provide an objective diagnostic standard for study on tongue inspection in the clinical practice and research of TCM.Number of references:27Main heading:Optical tomographyControlled terms:Biological organs - Diagnosis - Diseases - MicrostructureUncontrolled terms:Spleen-Stomach Dampness-Heat Syndrome (SSDHS) - Tongue Inspection (TI)Classification code:461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 461.7 Health Care - 741.3 Optical Devices and Systems - 951 Materials ScienceTreatment:Experimental (EXP)DOI:10.1117/12.758455Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

On one hand, service providers want to authenticate legitimate users. On the other hand, mobile users would prefer not to expose any information which enables anyone, including service providers, to get some clue regarding their whereabouts. To resolve this dilemma, we propose an anonymous authentication protocol to protect mobile users' privacy during the interactions between users and service providers in LBS. In this protocol, the service providers use blind signature to generate an authorized anonymous ID for the user, and then the user uses ring signature to mix the anonymous ID into a group of authorized IDs. We formally verity the correctness of the authentication and key establishment procedure in the protocol. In some practical situations, our protocol provides an efficient mechanism for balancing users' need for high-quality information services against their need for privacy protection. &copy; 2008 IEEE.Number of references:10Main heading:Computer networksControlled terms:Access control - Authentication - Data structures - Global system for mobile communications - Information services - Mobile computing - Wireless networks - Wireless telecommunication systemsUncontrolled terms:Anonymous authentication protocol - Blind signature - Key establishments - Legitimate users - Location based services - Mobile users - One hands - Privacy protections - Ring signature - Service providersClassification code:903.4 Information Services - 723.3 Database Systems - 723.2 Data Processing and Image Processing - 723 Computer Software, Data Handling and Applications - 722.4 Digital Computers and Systems - 722.3 Data Communication, Equipment and Techniques - 722 Computer

Considering the imperfect extinction ratio and the spontaneous emission of the practical Laser, vacuum states are not prepared easily. So in this paper, the optimal situation of the decoy state protocol applied to the QKD system with heralded single photon source (HSPS) is complemented and extended. The two weak decoy state protocol and the one decoy state protocol are proposed. At last, the theory of dual detectors is combined with the QKD system with HSPS. In the simulation, the secure distance is up to 221.5 km, which is approximately 50 km more than that of the on-off detectors.Number of references:26Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The pulse which had been discarded on the BB84 protocol phase coding QKD system is used to realize the time coding protocol, thus the useful bits rate in the present scheme can be doubled. At the same time, the phase coding keys and the time coding keys are obtained, we may combine both as new keys which can enhance the generated rate and the sensitivity of monitor. At Bob's side, a Fraday-Michelson is used instead of a traditional M-Z interferometer, which improves the stability of the interference visibility. With the proposed experimental setup, a stable quantum key distribution was performed over 90 km fiber.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:The integrated circuit (IC) design technology has made the chip density continue to increase. The high performance chips have a high sensitivity to the slightest defects in manufacturing procedure, therefore the defect detection is needed in order to ensure the performances of chip and semiconductor device. For the defects on a wafer, a detection method using image segmentation is presented in this paper. The method performs the segmentation of wafer image by selecting the threshold values. The optimal thresholds are computed by the technique based on cultural algorithm. The designs of population space, the belief space, and communication protocol in the cultural algorithm, are given in detail. An integration of genetic algorithm and simulated annealing is used to produce the new individuals in the population space. The experimental results show that the defect detection method proposed in this paper can obtain the features of defects effectively, the better image about the defect on a wafer can be obtained if the differential chart of the original image and the intact image of wafer is computed in advance. &copy; 2008 SPIE.Number of references:15Main heading:DefectsControlled terms:Algorithms - Communication - Digital image storage - Image segmentation - Imaging systems - Integrated circuits - Mechanical variables measurement - Semiconductor device manufacture - Simulated annealingUncontrolled terms:Belief spaces - Chip densities - Communication protocols - Cultural algorithms. - Defect detection - Defect detection methods - Detection methods - High sensitivities - IC wafers - Integrated circuit designs - Manufacturing procedures - Optimal thresholds - Original images - Population spaces - Wafer - Wafer imagesClassification code:741.1 Light/Optics - 741.3 Optical Devices and Systems - 746 Imaging Techniques - 741 Light, Optics and Optical Devices - 921 Mathematics - 943.2 Mechanical Variables Measurements - 951 Materials Science - 933.1 Crystalline Solids - 723.2 Data Processing and Image Processing - 531.2 Metallography - 537.1 Heat Treatment Processes - 714.2 Semiconductor Devices and Integrated Circuits - 423 Non Mechanical Properties and Tests of Building Materials - 716 Telecommunication; Radar, Radio and Television - 722.4 Digital Computers and Systems - 723 Computer Software, Data Handling and Applications - 722.1 Data Storage, Equipment and TechniquesDOI:10.1117/12.819710Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

In order to ensure this security, many approaches have been proposed recently. One of them is to use key predistribution schemes (KPSs) by means of combinatorial designs. In this paper, we use the Bush's construction of orthogonal arrays to present a class of key predistribution schemes for distributed sensor networks.

The laser-induced photoacoustic waves were detected by a piezoelectric double-ring sensor. This double-ring sensor has the advantage that it is more sensitive in the forward direction compared with other conventional sensors. An optical fiber for illumination of the sample was integrated with the sensor, which enabled reflection-mode detection of ultrasonic waves. Consequently, two-dimension photoacoustic tomography of biological tissues could be obtained in a manner analogous to the ultrasound B-scan mode by a linear scan over the tissue surfaces. To reach a large depth, 1064nm laser light was used in our experiments. The experimental results showed that the reconstructed photoacoustic images agree well with the structures of the samples. It demonstrated that this sensor has potential to monitoring tumor angiogenesis, and antiangiogenic therapy in vivo.Number of references:17Main heading:TissueControlled terms:Image sensors - Photoacoustic effect - Piezoelectric devices - Ultrasonic wavesUncontrolled terms:Antiangiogenic therapy - Laser light - Scanning photoacoustic tomography - Thermoelastic expansionClassification code:461.2 Biological Materials and Tissue Engineering - 704 Electric Components and Equipment - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 751.1 Acoustic Waves - 753.1 Ultrasonic WavesTreatment:Theoretical (THR); Experimental (EXP)Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

An experimental setup is specially designed to obtain the first-derivative spectrum, which aims to identify some unnoticeable absorption peaks in the normal PA spectrum. To enhance the detectability of overlapping spectral bands, the WT is used to decompose the PA spectrum signals into a series of localized contributions (details and approximation) on the basis of the frequency. For the decomposed contributions do not change the absorption peak position of PA spectrum, one can retrieve the weak absorption signals by the decomposed result of WT. Because of the use of derivative spectroscopy and WT, three unnoticeable absorption peaks that are hidden in the PA spectrum of carbon absorption are precisely retrieved, the wavelengths of which are 699.7, 752.7, and 775.5 nm, respectively. This analytical method, which has the virtue of using a physical method and using a computer software method, can achieve great sensitivity and accuracy for PA spectral analysis. &copy; 2008 American Institute of Physics.Number of references:20Main heading:Wavelet transformsControlled terms:Absorption spectra - Computer software - Photoacoustic spectroscopy - Sensitivity analysis - Spectrum analysis - WavelengthUncontrolled terms:Absorption signals - Overlapping spectral bands - Sensitive detection

We used the PA technique to measure the viscoelasticity of red blood cells (RBCs) to determine whether it could elucidate mechanical characteristics at a cellular level. A single-pulse laser beam was used as the light source to generate a PA signal. A "thin" glass was used as an acoustical impedance medium to form the attenuation signal. From the amplitude attenuation curves of the signals of a control RBC group and some glutaraldehyde-treated RBC groups, we obtained the decay times. As decay time is equal to the viscosity-elasticity ratio, we could obtain the viscoelasticity characteristics of the RBC. The PA technique is a simple, real-time, and noninvasive way to acquire the viscoelastic properties at a cellular level. &copy; 2008 American Institute of Physics.Number of references:15Main heading:Power amplifiersControlled terms:Acoustic impedance - Aldehydes - Blood - Boundary conditions - Elasticity - Light - Light sources - Lighting - Pulsed laser applications - Viscoelasticity - ViscosityUncontrolled terms:Cellular levels - Decay time - Decay times - Glutaraldehyde - Mechanical characteristics - Photoacoustic measurements - Red blood cells - Single-pulse lasers - Visco-elastic properties - Viscoelastic characterizationClassification code:921 Mathematics - 804.1 Organic Compounds - 751.2 Acoustic Properties of Materials - 744.9 Laser Applications - 741.1 Light/Optics - 931.2 Physical Properties of Gases, Liquids and Solids - 713.1 Amplifiers - 707 Illuminating Engineering - 631.1 Fluid Flow, General - 461.2 Biological Materials and Tissue Engineering - 421 Strength of Building Materials; Mechanical Properties - 707.2 Electric LampsDOI:10.1063/1.2949261Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The cumulant method which was used to inverse the size and polydispersity of nano-particle in PCS was analyzed. Three types of materials with five different sizes were measured by using PCS and the results showed that when the baseline methods were different, the value of baselines and the results of the effective diameter and polydispersity inversed by cumulant method were different, too. The reason was analyzed theoretically. It is pointed out that the autoslope method of acquiring baseline is the appropriate measured method.Number of references:10Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Tests were carried out using laser

clad layers as upper samples and GCr15 steel as lower samples with HT-500 abrasion tester. The results were compared with 40Cr's. The morphologies of wear scars were observed with optical microscopy. The tests show that the friction coefficient of 40Cr is bigger than the clad coating's with the load less than 250 g. The friction coefficient reduces with load increasing when the load is less than 300 g. The 40Cr's friction coefficient is (0.563-0.589) and increases with time when the load is 300 g. The friction coefficient of laser is (0.431-0.457) and clad layer decreases under the same condition. The performance of laser cladding becomes worse when the load is 500 g with the increase of wear time. The friction coefficient is 75% higher than that of 300 g and the wear depth increases by 47 times at the same time.Number of references:10Main heading:Laser claddingControlled terms:Friction - Iron alloys - Morphology - Optical microscopy - Protective coatings - Steel - Wear of materialsUncontrolled terms:Friction coefficient - Iron based alloy coating - Wear performanceClassification code:951 Materials Science - 931.2 Physical Properties of Gases, Liquids and Solids - 813.2 Coating Materials - 813.1 Coating Techniques - 744.9 Laser Applications - 545.3 Steel - 545.2 Iron AlloysTreatment:Experimental (EXP)Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Image segmentation is to partition an image into meaningful regions. An image segmentation approach based on chaotic ant colony algorithm is presented in this paper. The approach performs the image segmentation by selecting the optimal threshold values, where the multi-threshold values are used. First of all, an entropy function corresponding to an image is defined. The optimal threshold values are obtained by making the entropy function reach the maximal value. Secondly, an approach based on ant colony algorithm is presented for the computation of the optimal thresholds. In order to improve the computation performance of ant colony algorithms, for example, to avoid the algorithm search being trapped in local optimum, we use chaotic approach to find a better solution whenever all the ants have finished the operations. The chaotic approach searching the space around the ant which is the best so far. Besides, the initial solutions are generated by chaotic approach, this improves the quality of initial ants. The experimental results show that the approach proposed in this paper can get the near optimal threshold.Number of references:18Main heading:Image segmentationControlled terms:Algorithms - Chaotic systems - Computation theoryUncontrolled terms:Chaotic ant colony algorithm - Optimal threshold valuesClassification code:721.1 Computer Theory, Includes Formal Logic, Automata Theory, Switching Theory, Programming Theory - 723.2 Data Processing and Image Processing - 961 Systems ScienceTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1117/12.756538Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

It is found that, by means of this model, the color of silvery white of SG can be explained easily and the average reflectivity (AR) increases monotonously with the increase of the periodicity for the all-wave and infrared light.

Abstract:The electronic structure of pure N-doped and In-N codoped wurtzite ZnO has been calculated by using first-principles ultra-soft pseudo-potential approach of the plane wave based upon the density functional theory, and the structure change, bandstructure, density of states, difference charge density and the influence of In-N codoped wurtzite ZnO by H atom were studied. The calculation results revealed that N-doped wurtzite ZnO caused formation of deep N acceptor levels in the band gap and the carriers (hole) were localized near the top of the valence band. But the codoping calculation revealed that the acceptor level shifted toward the lower-energy region and shallow acceptor level were fomed, which was broadened and showed delocalizing characters, owing to which the concentration of impurities and the stability of the system were enhanced. Our conclusions accord with the results of experiments, which confirms the fact that In-N codoping in wurtzite ZnO helps the formation of p-type ZnO. In addition, it was also pointed out that the presence of H atom reduces the efficiency of doping markelly, which should be avoided as much as possible.Number of references:39Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

human bladder cancer mucosa/submucosa tissues were studied in the spectral range from 300nm to 900nm in vitro. Diffuse reflection spectra of tissues were measured with a spectrophotometer with an integrating sphere attachment. The results of measurement show that diffuse reflection of normal bladder mucosa/submucosa tissue at each wavelength is obviously higher than that of superficial bladder cancer mucosa/submucosa tissue at the corresponding wavelength. The peaks in diffuse reflection spectra for normal bladder mucosa/submucosa tissues were 52.4% at 370nm, 60.7% at 520nm, 56.1% at 550nm and 75.5% at 660nm, respectively, while the peaks in diffuse reflection spectra for superficial bladder cancer mucosa/submucosa tissues were 43.7% at 320 nm, 33.4% at 520nm, 30.6% at 550nm and 70.2% at 660nm, respectively. There was a peak in diffuse reflection spectra for normal bladder mucosa/submucosa tissues at 370nm, and there was not a peak for superficial bladder cancer mucosa/submucosa tissues at 370nm. There was a peak in diffuse reflection spectra for superficial bladder cancer mucosa/submucosa tissues at 320nm and there was not a peak for normal bladder mucosa/submucosa tissues at 320nm.

MR PWI was performed respectively before and after acetazolamide administrated orally on a clinical 1.5 Tesla GE Signa MR fx/i whole-body MR system. The region of interest (ROI) was chosen in the bilateral frontal lobe to measure the value of rCBV, rCBF and MTT. The results show that there was statistical difference between the resting and acetazolamide (Acz)-activated animals in the values of the diameter of the vascular in the superficial layer of the mouse cortex by photoacoustic imaging and in the values of rCBV and rCBF (P&gt;0.05) of the rat by MRI. It was concluded that the method of PWI and photoacoustic imaging combined with the "ACZ stress test" can be used to evaluate the CVRC by measuring values of rCBV and rCBF and diameter of the vascular, respectively.Number of references:14Main heading:Magnetic resonance imagingControlled terms:Blood - Image processing - Imaging systems - Medical imaging - Photoacoustic effectUncontrolled terms:Cerebrovascular reserve capacity (CVRC) - Mouse cortex - Perfusion-weighted imaging (PWI) - Superficial layerClassification code:751.1 Acoustic Waves - 746 Imaging Techniques - 741.1 Light/Optics - 741 Light, Optics and Optical Devices - 701.2 Magnetism: Basic Concepts and Phenomena - 461.2 Biological Materials and Tissue Engineering - 461.1 Biomedical EngineeringTreatment:Theoretical (THR); Experimental (EXP)Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

In this method, during the LED packaging process, the light emitted from a GaN LED chip itself is employed to package the LED encapsulant, thereby eliminating the need to utilize a mold. Current injection into a bare LED chip, triggers a photosensitive epoxy to polymerize, leading to the formation of mushroom lamp cap on the LED chip. The emission properties of LEDs fabricated by this method, including their emission beam profiles and light outputs, were characterized. The results showed that a self-focusing effect happened with the addition of an epoxy on the chip. The simulation demonstrated that the geometry the encapsulant controlled the beam pattern of emission. Further, the self-focusing effect was believed to be caused by the combination of the threshold energy of epoxy polymerization, the beam pattern and the power output of the LED chip. &copy; 2008 Optical Society of America.Number of references:9Main heading:Light emitting diodesControlled terms:Charge injection - Encapsulation - Gallium nitride - Light emission - Photopolymerization - Trigger circuitsUncontrolled terms:Active packing methods - Epoxy polymerization - Self focusing encapsulatesClassification code:701.1 Electricity: Basic Concepts and Phenomena - 712.1.2 Compound Semiconducting Materials - 713.5 Other Electronic Circuits - 714.2 Semiconductor Devices and Integrated Circuits - 741.1 Light/Optics - 815.2 PolymerizationTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1364/OE.16.003680Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

By increasing the defect size or the thickness ratio of the two periodic layers, two defect modes shift to each other from the upper and lower frequency side of the forbidden gap, respectively, then merge at the midfrequency of the gap. Merging conditions for such defect modes are given. These defect modes are insensitive to the incident angle. Moreover, the electric fields at the central frequency of the bandgap could be designed to be strongly localized at just one interface between the defect and the periodic layers in the photonic crystal with low transmission. &copy; 2008 Optical Society of America.Number of references:15Main heading:Photonic crystalsControlled terms:Crystal atomic structure - Crystallography - Crystals - Defects - Electric fields - Epitaxial growth - Gallium alloys - Merging - Photonics - Powders - Silicon on insulator technology - Single crystalsUncontrolled terms:Defect modesClassification code:741.1 Light/Optics - 741.3 Optical Devices and Systems - 744 Lasers - 801.4 Physical Chemistry - 802.3 Chemical Operations - 951 Materials Science - 804 Chemical Products Generally - 931.3 Atomic and Molecular Physics - 933.1 Crystalline Solids - 933.1.1 Crystal Lattice - 933.1.2 Crystal Growth - 813 Coatings and Finishes - 723.2 Data Processing and Image Processing - 723.1 Computer Programming - 423 Non Mechanical Properties and Tests of Building Materials - 482.2 Minerals - 531.2 Metallography - 536 Powder Metallurgy - 549.3 Others, including Bismuth, Boron, Cadmium, Cobalt, Mercury, Niobium, Selenium, Silicon,

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:High fluence low-power laser irradiation (LPLI) can induce cell apoptosis which is mediated by a high level of mitochondrial reactive oxygen species (ROS) production; however the mechanism is still unclear. Here, we further studied the mitochondrial signaling pathways involved in the apoptotic process. Activation of caspase-9 indicated an apoptotic process occurred under the high fluence LPLI treatment. Increasing of dichlorodihydrofluorescein diacetate (H<inf>2</inf>DCFDA) fluorescence products showed a high level of mitochondrial ROS generation after irradiation. Cyclosporine A (CsA) has been reported to inhibit some kinds of apoptosis, which are especially mediated by ROS. The question is whether CsA has some effect on high fluence LPLI induced apoptosis. Results showed that CsA significantly delayed mitochondria depolarization, observably delayed cell death in response to high fluence LPLI treatment

demonstrating a significant protective role of CsA on the apoptotic process. These results suggest that high fluence LPLI induced cell apoptosis via some CsA-sensitive mitochondrial signal pathways.Number of references:33Main heading:Cell deathControlled terms:Laser radiation - Mitochondria - Oxygen - Patient treatmentUncontrolled terms:Low-power laser irradiation (LPLI) - Reactive oxygen species (ROS)Classification code:461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 461.9 Biology - 744 Lasers - 804 Chemical Products GenerallyTreatment:Theoretical (THR)DOI:10.1117/12.762118Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Unlike the direct coupling cases where the phase shift of lightwave depends only on the defect mode frequency, we found that for the waveguide coupling cases the waveguide length and the

dispersion relation must be also considered. By changing the waveguide length, the spectrum can exhibit periodically three-peak appearance, two-peak appearance, and flat top appearance. At frequencies close to the defect mode, the results of the coupled mode theory are in good agreement with the simulations using the finite-difference time-domain technique, verifying the validity of the theoretical model even in the complicated cases.Number of references:20Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The molecule has crystallographically imposed twofold symmetry with the Mn ^II atom on the twofold axis. In the 1,10-phenanthroline-5,6-diol ligand, each H atom of the two hydr-oxy groups is oriented towards the other hydr-oxy O atom. Both hydr-oxy groups form inter-molecular O - H [midline ellipsis] Cl hydrogen bonds with a single Cl atom of an adjacent mol-ecule. These hydrogen bonds connect the mol-ecules via operation of the mol-ecular twofold axis and the centre of inversion of the crystal lattice, forming a doubly-bridged one-dimensional structure with Mn atoms as the nodes. Strong aromatic &pi;-stacking between two anti-parallel neighbouring 1,10-phenanthroline-5,6- diol ligands also helps to stabilize the chain. &copy; 2008 International Union of Crystallography.

The experimental results showed that in the range of 400-1100 nm there were larger absorption coefficients (P &lt; 0.01) and smaller reduced scattering coefficients (P &lt; 0.01) for adenomatous colon tissues than for normal colon tissues, and there were smaller optical penetration depths for adenomatous colon tissues than for normal colon tissues, especially in the near-infrared wavelength. Thermal coagulation induced significant increase of the absorption coefficients and reduced scattering coefficients for the normal and adenomatous colon tissues, and significantly reduced decrease of the optical penetration depths for the normal and adenomatous colon tissues. The smaller optical penetration depth for coagulated adenomatous colon tissues is a disadvantage for laser-induced thermotherapy (LITT) and photodynamic therapy (PDT).

In a unique photoacoustic system, a single pulse laser beam was used as the light source for both cancer treatment and for concurrently generating ultrasound signals for photoacoustic imaging. The photoacoustic system was used to detect early tumor on the rat back, and the vascular structure around the tumor could be imaged clearly with optimal contrast. This system was also used to monitoring damage of the vascular structures before, during and after photodynamic therapy of tumor. This work demonstrates that photoacoustic imaging can potentially be used to guide photodynamic therapy and other phototherapies using vascular changes during treatment. Prospective application of photoacoustic imaging is to characterize and monitor the accumulation of gold nanoshells in vivo to guide nanoshell-based thermal tumor therapy.Number of references:15Main heading:Medical imagingControlled terms:Acoustic imaging - Diagnosis - Image resolution - Patient monitoring - Photoacoustic effect - Photodynamic therapy - Tumors

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Photodynamic therapy (PDT) induces cell apoptosis mainly by the mitochondrial pathway. The Bcl-2 family proteins play an important role in this pathway. However, the detailed mechanism is not elucidated. The current study was aimed to determine whether Bim, a BH3-only protein of Bcl-2 family, was involved during Photofrin-PDT-induced apoptosis in ASTC-a-1 and MCF-7 cell lines. The data show that massive reactive oxygen species (ROS) were generated firstly after Photofrin-PDT treatment, leading to the disappearance of the mitochondrial membrane potential. Furthermore, the activation of Bim and Bax were dynamically observed. Confocal imaging of the cells transfected with GFP-BimL demonstrated that BimL translocate to mitochondria occurred about 12 min after PDT treatment. Bax activation occurred about 15 min after PDT treatment. These results suggest that Bim, as an effectors, was involved in Photofrin-PDT-induced apoptosis.Number of references:16Main heading:Photodynamic therapyControlled terms:Cell death - Cell membranes - Confocal microscopy - Medical imaging - Mitochondria - ProteinsUncontrolled terms:Membrane potential - Photofrin - Reactive oxygen species (ROS)Classification code:746 Imaging Techniques - 744.9 Laser Applications - 741.3 Optical Devices and Systems - 804.1 Organic Compounds - 461.9 Biology - 461.2 Biological Materials and Tissue

that could be used to improve the function of mitochondria, and then rehabilitate exercise-induced damage and fatigue. Background Data: Many other studies in the past demonstrated that LIL had a cytoprotective effect, and a recent study also found that LIL could reduce muscular fatigue during tetanic contractions in rats. Methods: Cultured C2C12 myotubes were subjected to electrical stimulation or/and LIL irradiation at various intensities. Reactive oxygen species (ROS) were detected with a fluorescent probe (DCFH-DA) and mitochondrial function was assessed with an MTT assay. Results: The results showed that electrical stimulation at 20 ms, 5 Hz, and 45 V for 75 min can induce mitochondrial dysfunction in cultured C2C12 myotubes. Electrical stimulation-induced mitochondrial dysfunction was improved, but degeneration occurred with LIL at doses of 0.33-8.22 and 11.22-14.16 J/cm², respectively, and these changes were markedly increased with LIL at 0.33 and 1.34 J/cm², respectively. Conclusions: We conclude that treatment of myotubes with the proper dosage of LIL irradiation significantly diminished production of ROS and restored mitochondrial function, and this may provide a foundation for the use of photobiomodulation to treat exercise-induced mitochondrial dysfunction or skeletal muscular fatigue. &copy; 2008 Mary Ann Liebert, Inc.Number of references:37Main heading:Electromagnetic launchersControlled terms:Fatigue damage - Fluorescence spectroscopy - Irradiation - Lasers - Oxygen - Photoacoustic effect - Pulsed laser deposition - RadiationUncontrolled terms:Electrical stimulations - Fluorescent probing - In order - Low intensity laser irradiation - Low intensity lasers - Mitochondrial dysfunction - Mitochondrial functions - MTT assaying - Muscular fatigues - Myotubes - Reactive oxygen species (ROS)Classification code:951 Materials Science - 804 Chemical Products Generally - 744.9 Laser Applications - 744.1 Lasers, General - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 704.2 Electric Equipment - 657.1 Solar Energy and Phenomena - 622.2 Radiation EffectsDOI:10.1089/pho.2007.2125Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

In the present paper, low-pressure metal-organic chemical-vapour deposition (MOCVD) was used to infill the voids within synthetic opals with InP. The morphologies and optical properties of SiO<inf>2</inf> -InP photonic crystal were characterized by scanning electron microscopy and ultraviolet-visible spectrophotometry (UV-Vis). Several series of experiments were carried out in order to analyze the factors that influence the loading of InP in opals and determine the optimal InP growth conditions. The results of optical experiments are in good agreement with those derived from the theoretical considerations: By increasing the extent of InP infilling within the voids, the extent of refractive index contrast between the silica spheres and the void as well as the extent of natural optical properties change of the photonic crystal were increased. Cycle growth, low-pressure growth, and using the match substrate and the same configuration character between SiO<inf>2</inf> and InP are beneficial to increaseing the extent of InP infilling within the opal voids. The process has been optimized to achieve SiO<inf>2</inf> -InP photonic crystal with higher loading of InP. The study provides a scientific basis for manufacturing three-dimensional InP inverse opal photonic crystals.Number of references:20Main heading:Photonic crystalsControlled terms:Chemical vapor deposition - Crystal atomic structure - Energy gap - Gallium alloys - Growth (materials) - Optical devices - Optical microscopy - Optical properties - Organic chemicals - Organic compounds - Organic polymers - Photonic band gap - Refractive index - Scanning electron microscopy - Silica - Silicate minerals - Silicon compounds - Silicon on insulator technology - Three dimensionalUncontrolled terms:Artificial opal crystal - Growth conditions - Infilling - Influential factors - InP - Inverse opals - Key problems - MOCVD - MOCVD growths - Optical experiments - Pressure growths - Silica spheres - Synthetic opals - Ultra violets - Vapour depositionsClassification code:951 Materials Science - 804.2 Inorganic Compounds - 812 Ceramics, Refractories and Glass - 813.1 Coating Techniques - 815.1.1 Organic Polymers - 902.1 Engineering Graphics - 931.2 Physical Properties of Gases, Liquids and Solids - 931.3 Atomic and Molecular Physics - 933.1 Crystalline Solids - 933.1.1 Crystal Lattice - 933.1.2 Crystal Growth - 804.1 Organic Compounds - 482.2 Minerals - 549.3 Others, including Bismuth, Boron, Cadmium, Cobalt, Mercury, Niobium, Selenium, Silicon, Tellurium and Zirconium - 712.1 Semiconducting Materials - 712.1.2 Compound Semiconducting Materials - 802.3 Chemical Operations - 714.2 Semiconductor Devices and Integrated Circuits - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 802.2 Chemical Reactions - 723.5 Computer ApplicationsDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The objective of this study was to analyze the morphological characteristics induced by taxol. Human lung adenocarcinoma (ASTC-a-1) cells were exposed to various concentration of taxol. CCK-8 was used to assay the cell viability. Atomic force microscopy (AFM), plasmid transfection and confocal fluorescence microscopy were performed to image the cells morphological change induced by taxol. Fluorescence resonance energy transfer (FRET) was used to monitor the caspase-3 activation in living cells during taxol-induced cell death. Cells treated with taxol exhibited significant swelling and cytoplasmic vacuolization which may be due to endoplasmic reticulum (ER) vacuolization. Caspase-3 was not activated during taxol-induced cytoplasmic vacuolization and cell death. These findings suggest that taxol induces caspase-3-independent cytoplasmic vacuolization, cell swelling and cell death through ER vacuolization. &copy; 2008 Elsevier Ltd.

Box 80, Xi'an, 710068, ChinaAbstract:An image encryption method combining three steps phase-shifting interferometry with dyadic permutations in the joint transform correlator based architecture is proposed. With a phase-only spatial light modulators the original image and two random phase masks are modulated simultaneously. The image information and the principal key are encoded to interferograms by the three phase-shifting interferometry and the interferograms are recorded by a CCD camera at the output plane; then the interferogram of the original image by the dyadic permutations is permuted.

A spectrophotometer was used to measure the diffuse reflectance and total transmittance of the tissue samples, and the inverse adding-doubling (IAD) method was applied to assess the absorption coefficients, the reduced scattering coefficients and the optical penetration depth of tissue from the measurements. The results of measurement show that the absorption and reduced scattering coefficients and optical penetration depths of myocardium tissues vary with the change of irradiation wavelength. There are a positive peaks at 550 nm for the absorption coefficients of both native and thermocoagulated (treated with

80&deg;C) myocardium, and the peak values for native and thermocoagulated myocardium are 0.74 mm^-1 and 1.16 mm^-, respectively. There is a positive peak at 550 nm for the reduced scattering coefficients of native myocardium and the peak value is 0.25 mm^-1, whereas the peak disappears after myocardium tissue treated with high temperature. Further more a new increase appears at the wavelength range of 590-625 nm. The absorption coefficient of myocardium tissue is not significantly changed by treating with lower temperature but increases slightly with higher temperature. The reduced scattering coefficient of myocardium tissue is significantly increasing with the increase of treating temperature. And the optical penetration depth of myocardium tissue is significantly decreasing with the descrease of treating temperature.Number of references:19Main heading:TissueControlled terms:Heating - Infrared devices - Optical materials - Optical propertiesUncontrolled terms:Integrating-sphere - Inverse-adding-double method - Medical optics and biotechnology - Myocardium tissue - Slowly heated - Tissue opticsClassification code:461.2 Biological Materials and Tissue Engineering - 642.1 Process Heating - 643.1 Space Heating - 741.1 Light/Optics - 741.3 Optical Devices and SystemsDOI:10.3788/CJL20083505.0792Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Routing in WMN is a challenging problem as a result of highly dynamic topology as well as bandwidth and energy constraints. The Swarm Intelligence paradigm, such as Ant Colony Optimization (ACO), has recently been demonstrated as an active approach for routing in both wired and wireless networks. We designed a novel ACO-based multicasting routing algorithm. In the proposed algorithm, a source-based approach is adapted to build a multicast tree among all the multicast members, and an evolutional scheme for the original multicast tree is designed to find a more optimal multicast tree. In addition the evolutional scheme also acts as a local recovery technique when some intermediate nodes move away. Compared with ODMRP and MAODV, the proposed algorithm performs better in terms of average delay, success ratio and efficiency. &copy;2008 IEEE.Number of references:11Main heading:Wireless networksControlled terms:Cellular automata - Feature extraction - Local area networks - Multicasting - Network routing - Optimization - Pattern recognition - Routing algorithms - Trees (mathematics) - Wavelet analysis - Wavelet transforms - Wireless local area networks (WLAN)Uncontrolled terms:Ant Colony Optimization (ACO) - Ant Colony optimizations - Average delays - Challenging problems - Dynamic topologies - Energy constraints - Future generations - Intermediate nodes - Multicast - Multicast members - Multicast routing - Multicast trees - Multicasting routing algorithms - Routing - Success ratios - Swarm intelligences - Wired and wirelesses - Wireless Mesh Networks - Wireless mobile networksClassification code:723 Computer Software, Data Handling and Applications - 723.2 Data Processing and Image Processing - 723.5 Computer Applications - 741.1 Light/Optics - 751.1 Acoustic Waves - 921 Mathematics - 921.3 Mathematical Transformations - 921.4 Combinatorial

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:Nafion membrane was modified with polyaniline by electrochemical methods, including constant current, constant potential and potential cycling. The methanol permeability and the proton conductivity of the Nafion membranes with and without modification were determined by the electrochemical oxidation of the permeated methanol and electrochemical impedance spectroscopy, respectively. It is found from FTIR results that the polyaniline formed by electrochemical method is in emeraldine state. With the modification of polyaniline, the methanol permeability of the Nafion membrane is reduced by one decade but there is only a slight decrease in proton conductivity. The power density output of direct methanol fuel cell using polyaniline-

modified Nafion membrane is 40% larger than that using pure Nafion membrane. The modification with polyaniline is better than that with polypyrrole. The methanol permeability of the polyaniline-modified Nafion is about half of that of the polypyrrole-modified Nafion but the proton conductivity of the former is higher than the later. &copy; 2008 Elsevier B.V.

Publisher:Science Press, Beijing, 100085, ChinaAbstract:In this paper, we theoretically investigated the influence of nonlocality on (1 + 2)-dimensional spatial solitons in undoped nematic liquid crystals (NLCs). We confirmed that the nonlinear index coefficient and the general characteristic length of the nonlinear nonlocality for the NLC are dependent on the pretilt angle of the NLC molecules. Then the Schrodinger-type nonlinear equation in strong nonlocality was given and from the equation the analytical expressions of the single soliton and the critical power were respectively obtained. In experiment, we varied the degree of nonlocality by changing the bias voltage and indirectly determined the relation between the critical power and pretilt angle. At last, by comparison of analytical solutions with the numerical simulation and the experimental result, we verified that our expressions are precise.Number of references:17Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

A series of differential equations which describe the evolutions of the width, the phase, the phase front curvature, and the amplitude of the beam are obtained. The critical power for a beam propagating as a spatial optical soliton in weakly nonlocal nonlinear media is also obtained. A quantitative depiction of the steadying effect of nonlocality on the propagation of a beam is obtained through the steadiness analyse, which provides a self-consistent explanation of the transition from unsteady local kerr solitons to steady weakly nonlocal solitons. The results of numerical method agree with that of variational calculations, implying that hyperbolic secant function is a good approximation to a (2 + l)D weakly nonlocal spatial optical soliton.

Box 1831, Birmingham, AL 35201-1831, United StatesAbstract:This paper analyzes the contents of 16 trace elements in the strata of the Chagelebulu Stratigraphic Section, Badain Jaran Desert, since 150 kyr B.P. and discovered that both the contents of the relatively stable elements, such as P, Mn, Zr, Cr, Pb, Rb, Nb, Y, and the relatively active elements, such as V, Sr, Ni, Cu, Zn, As fluctuated with the sedimentary cycles composed of 25 aeolian dune sands, loess, paleosols, lacustrine facies, alluvial, and colluvial sandy gravels, showing 25 cycles of low-high variation and a fluctuant jagged graph of chemical elements' migration and accumulation. The lower contents of the elements in the aeolian sands show the erosion, migration and deposition of wind power in a cold and arid climate. The relative accumulation of sandy-gravel layers, especially the lacustrine facies, loess, and paleosols correlates with the section's position in the special depression relief with a background of warm and humid climate. The above-mentioned variational characteristics were mainly caused by 25 cycles of arid-cold, windy, and warm-humid climatic fluctuation on the southern fringe of the Badain Jaran Desert since 150 kyr B.P. The essential reason bears a relationship with the back and force swing of the East Asia winter monsoon and summer monsoon influenced by climatic vicissitudes during the glacial and interglacial periods. &copy; MAIK Nauka 2008.

Then we can get one-dimensional (ID) images from the electronic signals using a peak detection-and-hold circuit. After vertical scanning with a stepping motor on the imaging plane, a 2D PA image of the sample is successfully obtained. Combined with the time-resolved technique, we can then get 3D PAT images. The results show that the reconstructed images agree well with the original samples. &copy; 2008 Optical Society of America.Number of references:18Main heading:LensesControlled terms:Imaging systems - Photoacoustic effect - Tomography - TransducersUncontrolled terms:Peak hold technology - Photoacoustic tomography imagingClassification code:704 Electric Components and Equipment - 741.1 Light/Optics - 741.3 Optical Devices and Systems - 746 Imaging Techniques - 751.1 Acoustic Waves

The multi-element linear transducer array consists of 64 elements. By utilizing an acoustic lens, the PA signals generated from the sample are imaged and detected by a multi-element linear transducer array, which directly changes the PA signals into the homologous electronic signals. Thus we can map the image more rapidly, with the peak detection circuit, which was designed specially. Compared to other exiting technology and algorithm, the PA imaging system based on an acoustic lens and the peak detection technology was characterized with speediness and real-time. The images reconstructed in this experiment have high definition and resolution, and may have potential for developing an appliance for clinical diagnosis.Number of references:13Main heading:Acoustic imagingControlled terms:Algorithms - Image reconstruction - Imaging systems - Photoacoustic effect - Real time systems - TransducersUncontrolled terms:Clinical diagnosis - Electronic signals - Multi-element linear transducer array - Peak detection technology - Photoacoustic systemClassification code:751.2 Acoustic Properties of Materials - 751.1 Acoustic Waves - 746 Imaging Techniques - 741.1 Light/Optics - 723 Computer Software, Data Handling and Applications - 722.4 Digital Computers and Systems - 704 Electric Components and Equipment

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Photoacoustic imaging technique, which provided high ultrasonic resolution and high optical contrast tissue images, can overcome the disadvantages of pure optical imaging by measurement of laser-induced sound waves. The waves produced by tissue are high-frequency ultrasounds, meaning that they cannot be heard by human ear. However, it can be picked up with ultrasonic transducer and analyze them with a computer. The laser-induced ultrasonic signals from a biological sample can be used to reveal the tissues structure based on optical contrast. In current experiment system, an integrity multi-element synthetic aperture focusing (M-SAF) photoacoustic imaging system using real-time digital beamformer is developed. This system relies on pumping laser source to irradiate the biological tissue to produce photoacoustic signal, a linear ultrasonic transducer array is connected to a multichannel signal acquisition and real-time digital beam-formation system providing techniques of real-time dynamic receiving focus and dynamic receiving apodization to process the photoacoustic signal. Each element of the transducer array has a thin cylinder ultrasonic lens to select 2D image plane and suppress the out-of-plane signals to realize photoacoustic computed tomography. This method and system can provide a fast and reliable photoacoustic tomography approach that could be applied to noninvasive imaging and

Two solitons in close proximity can be intertrapped via the strong nonlocality, and propagate together as a whole. The trajectory of the propagation is a straight line with a slope controlled by the phase difference. Experimental results carried out in nematic liquid crystals agree quantitatively with the prediction. The modification of the Snyder-Mitchell model is also discussed. Our study suggests that the phenomenon in which optical beams can be steered by controlling the phase difference could be used in all-optical information processing. &copy; 2008 The American Physical Society.Number of references:34Main heading:Solitons

Researchers have dedicated much effort for detecting singlet oxygen and suqeroxide anion. FCLA (the fluoresceinyl cypridina luciferin analog) is a singlet oxygen and superoxide anion specific chemiluminescence probe. Typical chemiluminescence signal is relatively weak and its detection at single cell level is rather difficult. In the present study, the fluorescence of FCLA at 515 nm was investigated and was found to increase significantly during the ROS oxidative reaction. With fluorescence imaging technique, ROS can be detected by evaluating the spatial distribution and the dynamic changes in FCLA fluorescence. The technique is proved to have high sensitivity and excellent signal-to-noise ratio compared to direct CL measurement. With minimal

cytotoxicity and excellent ROS selectivity, the FCLA fluorescence imaging technique can be a powerful new means in real-time in vivo and in situ single oxygen detection at the single cell level.Number of references:18Main heading:OxygenControlled terms:Chemiluminescence - Fluorescence - Imaging systems - Imaging techniques - Ions - Light emission - Light measurement - Luminescence - Negative ions - Nonmetals - Photodynamic therapy - Signal to noise ratioUncontrolled terms:Chemiluminescence probes - Chemiluminescence signals - Cl measurements - Cyp- ridina luciferin analogs - Dynamic changes - FCLA - Fluorescence imaging - High sensitivities - In-situ - In-vivo - Oxidative reactions - Plant stresses - Reactive Oxygen species - Signal-to-Noise ratios - Single cells - Single oxygens - Singlet oxygen - Singlet oxygens - Spatial distributions - Superoxide - Superoxide anionClassification code:931.3 Atomic and Molecular Physics - 804 Chemical Products Generally - 802.2 Chemical Reactions - 801 Chemistry - 746 Imaging Techniques - 941.4 Optical Variables Measurements - 741.1 Light/Optics - 723.2 Data Processing and Image Processing - 716.1 Information Theory and Signal Processing - 701.1 Electricity: Basic Concepts and Phenomena - 461.6 Medicine and Pharmacology - 741 Light, Optics and Optical DevicesDOI:10.3964/j.issn.1000-0593(2008)11-2633-03Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Abstract:The characteristics of taxol-induced-ASTC-a-1 PCD resembling paraptosis were studied by fluorescence probes and confocal microscope. The erRFP plasmid was used to probe the endoplasmic reticulum, and the GFP plasmid was used to probe the change of cells shape. Rhodamine 123 was used to probe the mitochongdria, and the Hoechst33258 was used to probe the nuclear condensation and DNA cleavage, and PI was used to verify the breakage of cells membrane. Our results show that taxol induced ASTC-a-1 cell paraptosis is caused by progressive swelling of mitochondria and the endoplasmic reticulum, and the taxol-induced concentration-dependent cytoplasm vacuolization is independent of caspases inhibited by z-VAD-fmk. Hoechst33258 experimental results show that taxol did not induce nuclear condensation cell apoptosis and cells membrane breakage which is the typical characteristics of cell necrosis. Taxol induces the ASTC-a-1 cells paraptosis by cytoplasm vacuolization due to swelling of the endoplasmic reticulum and the mitochondria.Number of references:14Main heading:ProbesControlled terms:Cell death - Cell membranes - Cells - Condensation - Cytology - Fluorescence - Mitochondria - Nucleic acids - Organic acidsUncontrolled terms:Caspases - Cell apoptosis - Cell necrosis - Concentration dependents - Confocal microscopes - Cytoplasm vacuolization - DNA cleavages - Endoplasmic reticulums - Fluorescence analysis - Fluorescence probes - Human lungs - Paraptosis - Programe cell death(PCD) - Rhodamine 123 - TaxolClassification code:943 Mechanical and Miscellaneous Measuring Instruments - 942 Electric and Electronic Measuring Instruments - 941 Acoustical and Optical Measuring Instruments - 804.1 Organic Compounds - 944 Moisture, Pressure and Temperature, and Radiation Measuring Instruments - 802.3 Chemical Operations - 741.1 Light/Optics - 461.9 Biology - 461.2 Biological Materials and Tissue Engineering - 801.2 BiochemistryDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Publisher:Sun Yat-sen (Zhongshan) University, 135 Xingangxilu, Guangzhou, 510275, ChinaAbstract:Remote sensing has long time been an important component of regional planning for applications ranging form urban fringe change detection to monitoring change detection of land use. On the other hand, the technologies and methods of change detection also have evolved dramatically during past 20 years. So it has been well recognized that the change detection had become the best methods for researching dynamic change of land use by multi-temporal remotely-sensed data. The purpose of this paper is to detect land use change surrounding the area of Guangzhou using TM image (Dec 22, 1998) and ETM+ image (Jan. 10, 2003). A county administrative boundary vector layer of the Pearl River Delta (2000) was used to get the subset image of Guangzhou. Unsupervised classification is performed by the K-Means method. At last, two-time subset images of Guangzhou are compared on a pixel-by-pixel basis using the post-classification comparison method and the from-to change matrix is produced, the land use change information obtained.Number of references:15Main heading:Land useControlled terms:Classification (of information) - Copying - Pixels - Planning - Regional planning - Remote sensing - Signal detection - Space opticsUncontrolled terms:Change detection - Comparison methods - Dynamic changes - ETM+ image - Guangzhou - K-means method - Land use changes - Land use/land cover - Long time - Multi-temporal - Pearl River delta - Post-classification - RS data - TM images - Unsupervised classificationClassification code:745.2 Reproduction, Copying - 731.1 Control Systems - 722.2 Computer Peripheral Equipment - 912.2 Management - 716.1 Information Theory and Signal Processing - 403.2 Regional Planning and Development - 403 Urban and Regional Planning and Development - 656.1 Space FlightDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Low-power laser irradiation (LPLI) leads to photochemical reaction and then activates intracellular several signaling pathway. Reactive oxygen species (ROS) are considered to be the primary messengers produced by LPLI. Here, we studied the signaling pathway mediated by ROS upon the stimulation of LPLI. Src tyrosine kinases are well-known targets of ROS and can be activated by oxidative events. Using a Src reporter based on fluorescence resonance energy transfer (FRET) technique, we visualized the dynamic Src activation in Hela cells immediately after LPLI. Moreover, Src activity was enhanced by increasing the duration of LPLI. In addition, our results suggested that ROS were key mediators of Src activation, as ROS scavenger, vitamin C decreased and exogenous H <inf>2</inf>O<inf>2</inf> increased the activity of Src. Meanwhile, Go&die;6983 loading did not block the effect of LPLI. CCK-8 experiments proved that cell vitality was prominently improved by LPLI with all the doses we applied in our experiments ranging from 3 to 25J/cm². The results indicated that LPLI/ROS/Src pathway may be involved in the LPLI biostimulation effects.Number of references:14Main heading:CellsControlled terms:Energy transfer - Enzyme activity - Fluorescence - Laser beam effects - Resonance - VitaminsUncontrolled terms:Dynamic activation - Low-power laser irradiation (LPLI) - Reactive oxygen species (ROS)Classification code:931.1 Mechanics - 744.8 Laser Beam Interactions - 741.1 Light/Optics - 525.4 Energy Losses (industrial and residential) - 461.9 Biology - 461.7 Health Care - 461.2 Biological Materials and Tissue EngineeringTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1117/12.760229Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

However, the molecular mechanism of CS-induced-apoptosis is still unclear. This study investigated the molecular mechanism of CS-induced apoptosis using fluorescence resonance energy transfer (FRET) and confocal fluorescence microscope techniques. CS dose-dependently inhibited cell viability cytotoxicity, which was assayed by Cell Counting Kit (CCK-8) and Hoechst33258 staining. Bax translocation to mitochondria was observed in single living cell transfected with GFP-Bax plasmid. The mitochondrial membrane potential (&Delta;&Psi;<inf>m</inf>) loss was also measured in CS-treated cells. And ASTC-a-1 cell expressed stably with SCAT3 plasmid was used to examine if caspase-3 was activated by CS. z-VAD-fmk, a broad-caspase spectrum inhibitor, was found to significantly reduce the inhibition of CS on the cell viability. Overall, our data demonstrated that CS induced ASTC-a-1cells apoptosis in a dose-dependent manner, and Bax, caspase-3 and mitochondrial stress were involved in CS-induced apoptosis. Our findings extend the knowledge about the cellular signaling mechanisms mediating CS-induced apoptosis. &copy; 2008 - IOS Press and the authors.

The response function is exponential-decay function in NLC, which is different from the Snyder-Mitchell model. Through numerical simulations, we discovered that the crosspoint of soliton interaction is in inverse proportion to the square root of injection power in NLC. We also found that the position of crosspoint is independent of the distance between solitons in strong nonlocal Gauss function response, but it is not the same with exponential-decay function in NLC. Through experiments, we found the positions of crosspoint is in inverse proportion to the square root of inject power, it is also related to the critical power of soliton formation and the distance between solitons.Number of references:15Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 14965/159, Teheran, 14977, IranAbstract:Instead of the traditional two-step method with cyclic intermediates, a direct reaction of D,L-lactic acid (D,L-LA) and glycine (Gly) as monomers (molar feed ratio LA/Gly: 90/10) and SnO (0.7 wt%) as catalyst is carried out to synthesize a biodegradable poly(lactic acid-co-glycine) [P(LA-co-Gly)] via melt copolycondensation at 170&deg;C, absolute pressure of 70 Pa, for 8 h, following a prepolymerization step. The structure of the copolymer was characterized by FTIR and ¹H NMR techniques. The GPC results show that the weight average molecular weight (M&macr;<inf>w</inf>) of the copolymer P(LA-co-Gly) is 3600 g/mol. Under the condition of different molar feed ratios the highest M&macr;<inf>w</inf> was found to be 5200 with molar feed ratio LA/Gly:98/2. Other characterizations, e.g., intrinsic viscosity, solubility, DSC, and XRD indicated that the copolymer solubility in chloroform and tetrahydrofuran (THF) decreased with the increasing feed charge of Gly and the lowest solubility was found when the molar feed ratio was below LA/Gly:70/30. However, the modified polylactic acid is readily soluble in DMSO. The crystallinity of copolymer gradually disappears as the molar feed ratio of D,L-LA decreases. For LA/Gly &ge; 90/10, the XRD pattern has two diffraction peaks, close to 16.8&deg; and 19.1&deg;, the same position as poly(D,L-lactic acid) (PDLLA). For the soluble P(LA-co-Gly) the intrinsic viscosity, M&macr;<inf>w</inf> and its dispersity (M&macr;<inf>w</inf>/M&macr;<inf>n</inf>) decrease gradually with the increase of feed charge of Gly. These results, especially the molecular weight of the copolymer appear to meet the requirements necessary for a drug delivery applications.Number of references:40Main heading:Organic polymersControlled terms:ABS resins - Acids - Body fluids - Characterization - Copolymerization - Dimethyl sulfoxide - Drug delivery - Fourier transform infrared spectroscopy - Hydrodynamics - Lactic acid - Molecular weight - Monomers - Nuclear magnetic resonance - Organic acids -

Document type:Journal article (JA)Publisher:Science Press, 18,Shuangqing Street,Haidian, Beijing, 100085, ChinaAbstract:Theoretical calculations via the transfer matrix method (TMM) are performed to investigate optical properties of one-dimensional semiconductor-organic photonic crystals (SOPC) with periodic conjugated polymer (3-octylthio-phenes, P30T)/AlN multilayer structure. The SOPC presents incomplete photonic band gap behavior in the UV region. P30T/AlN multilayers with two pairs of 30 nm-P3OT and 30 nm-AlN layers exhibit a photonic band gap at a central wavelength of about 275 nm, and the highest reflectivity reaches 98%. Furthermore, the band gaps are confirmed to be tunable by adjusting the lattice period and the filling fraction. As a consequence, the SOPC is important for achieving materials with an incomplete band gap in the UV region.Number of references:18Main heading:Photonic band gapControlled terms:ABS resins - Crystal atomic structure - Crystal structure - Crystallography - Electric conductivity - Energy gap - Gallium alloys - Multilayer films - Multilayers - Optical devices - Optical materials - Optical multilayers - Optical properties - Periodic structures - Photonic crystals - Photonics - Polymer films - Polymers - Powders - Semiconducting organic compounds - Semiconductor materials - Silicon on insulator technology - Transfer matrix methodUncontrolled terms:AlN - AlN layers - Band gaps - Central wavelengths - Filling fractions - Lattice periods - Multilayer structures - Organic photonic crystals - Photonic bands - Semi-conductors - Theoretical calculations - TMM method - Transfer matrixes - UV regionsClassification code:933.1.1 Crystal Lattice - 744 Lasers - 801.4 Physical Chemistry - 804 Chemical Products Generally - 813.2 Coating Materials - 815.1 Polymeric Materials - 815.1.1 Organic Polymers - 921 Mathematics - 931.3 Atomic and Molecular Physics - 933 Solid State Physics - 933.1 Crystalline Solids - 741.3 Optical Devices and Systems - 531.2 Metallography - 536 Powder Metallurgy - 549.3 Others, including Bismuth, Boron, Cadmium, Cobalt, Mercury, Niobium, Selenium, Silicon, Tellurium and Zirconium - 701.1 Electricity: Basic Concepts and Phenomena - 741.1 Light/Optics - 712 Electronic and Thermionic Materials - 712.1.2 Compound Semiconducting Materials - 714.2 Semiconductor Devices and Integrated Circuits - 717 Optical Communication - 712.1 Semiconducting MaterialsDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:In the current circuit design technology, due to increasing device density and operation speed, crosstalk effects are induced between circuit elements. A new method for the detection of crosstalk faults in digital circuits is presented in this paper, the method is based on both the energy function model of digital circuits and the chaotic ant colony algorithms. First of all, the energy function models of basic gate circuits are constructed, then the energy function corresponding to a digital circuit is built. The energy function of a circuit is the summation of all energy functions of the gates in the circuit. The test vectors of crosstalk delay faults in the circuit are produced by computing the minimal energy states of energy functions. Secondly, a chaotic ant colony algorithm is designed to compute the minimal energy states. Experimental results show the method proposed in this paper is able to produce the test vectors of crosstalk delay faults if there are the test vectors for the faults, therefore the high fault coverage can be obtained by the proposed method. &copy; 2008 SPIE.Number of references:14Main heading:Integrated circuit manufactureControlled terms:Crosstalk - Delay circuits - Digital integrated circuits - Fault detection - Global optimization - Mechanical variables measurement - VLSI circuitsUncontrolled terms:Ant colony algorithms - Circuit elements - Crosstalk delays - Crosstalk effect - Crosstalk faults - Current circuits - Delay faults - Detection methods - Energy function - Energy state - Fault coverages - Gate circuits - If there ares - Operation speed - Test vectorsClassification code:943.2 Mechanical Variables Measurements - 921.5 Optimization Techniques - 721.3 Computer Circuits - 718.1 Telephone Systems and Equipment - 716.3 Radio Systems and Equipment - 714.2 Semiconductor Devices and Integrated Circuits - 713.5 Other Electronic Circuits - 711.1 Electromagnetic Waves in Different Media - 706.2 Electric Power Lines and Equipment - 703.1 Electric Networks - 422 Strength of Building Materials; Test Equipment and MethodsDOI:10.1117/12.819774Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Ultraviolet (UV) irradiation can induce apoptosis through both the membrane death receptor and the intrinsic apoptotic signaling pathways as DNA-damaging agents. PUMA, a BH3-only Bcl-2 family protein, plays an essential role in DNA damage-induced apoptosis. Bax, also a Bcl-2 family member, translocates from the cytosol to the mitochondrial membrane during UV-induced apoptosis. However, the regulation of Bax activation induced by UV irradiation remains poorly understood. In this study, the FRET (fluorescence resonance energy transfer) technique was used to study the interactions of Bax, Bcl-Xl, and PUMA in ASTC-a-1 cells. The results show that Bax translocated from the cytosol to the mitochondrial membrane at about 7 h after UV irradiation, and the translocation can not be blocked completely when overexpressed Bcl-xl. Moreover, The interaction of Bax and Bcl-Xl weakened markedly. In addition, Co-immunoprecipitation shows that PUMA released Bax by directly binding to Bcl-XL after UV irradiation in ASTC-a-1 cells. Taken together, these results indicated that PUMA can promote Bax translocation by binding to BcI-Xl during UV-induced apoptosis.Number of references:28Main heading:Cell deathControlled terms:DNA sequences - Mitochondria - Proteins - Ultraviolet radiationUncontrolled terms:Bax translocation - Competitive bindingClassification code:461.2 Biological Materials and Tissue Engineering - 461.9 Biology - 741.1 Light/Optics - 804.1 Organic CompoundsTreatment:Theoretical (THR)DOI:10.1117/12.762028Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 3337, Columbus, OH 43210-3337, United StatesAbstract:A bio bar code assay based on oligonucleotide-modified gold nanoparticles (Au-NPs) provides a PCR-free method for quantitative detection of nucleic acid targets. However, the current bio bar code assay requires lengthy experimental procedures including the preparation and release of bar code DNA probes from the target-nanoparticle complex and immobilization and hybridization of the probes for quantification. Herein, we report a novel PCR-free electrochemiluminescence (ECL)-based bio bar code assay for the quantitative detection of genetically modified organism (GMO) from raw materials. It consists of tris(2,2&prime;- bipyridyl) ruthenium (TBR)-labeled bar code DNA, nucleic acid hybridization using Au-NPs and biotin-labeled probes, and selective capture of the hybridization complex by streptavidin-coated paramagnetic beads. The detection of target DNA is realized by direct measurement of ECL emission of TBR. It can quantitatively detect target nucleic acids with high speed and sensitivity. This method can be used to quantitatively detect GMO fragments from real GMO products. &copy; 2008 American Chemical Society.Number of references:34Main heading:Bar codesControlled terms:Chemiluminescence - Gold - Nanoparticles - Nucleic acids - Oligonucleotides - Sensitivity analysisUncontrolled terms:Electrochemiluminescence - Quantitative detectionClassification code:933 Solid State Physics - 921 Mathematics - 804.1 Organic Compounds - 802.2 Chemical Reactions - 801.2 Biochemistry - 761 Nanotechnology - 741.1 Light/Optics - 723.2 Data Processing and Image Processing - 547.1 Precious Metals - 461.9 Biology - 461.2

It can provide an effective approach of tissue structure and functional images to study the architectures, physiological and pathological properties and metabolisms of biological tissues. This paper is focused on photoacoustic and thermoacoustic imaging application in cancer early detection and treatment monitoring. A unique photoacoustic imaging system was used to detect tumors neovascularization associated with angiogenesis in a rat animal model. We also developed the imaging system to monitor the vascular damage during photodynamic therapy treatment. This method could be potentially used to guide PDT and other phototherapies using vascular changes during treatment to optimize treatment

It is revealed that the value and sign of the differential reflection strongly depend on the thickness of the cap layer and the QD layer. In addition, a comparison between the carrier dynamics in undoped and p -doped InAsGaAs QDs is carried out by pump-probe reflection measurements. The carrier capture time from the GaAs barrier into the InAs wetting layer and that from the InAs wetting layer into the InAs QDs are extracted by appropriately fitting differential reflection spectra. Moreover, the dependence of the carrier dynamics on the injected carrier density is identified.

On the other hand, the technologies and methods of change detection also have evolved dramatically during past 20 years. So it has been well recognized that the change detection had become the best methods for researching dynamic change of land use by multi-temporal remotely-sensed data. The purpose of this paper is to detect land use change surrounding the area of Guangzhou using TM image (Dec 22, 1998) and ETM+ image (Jan. 10, 2003). A county administrative boundary vector layer of the Pearl River Delta (2000) was used to get the subset image of Guangzhou. Unsupervised classification is performed by the K-Means method. At last, two-time subset images of Guangzhou are compared on a pixel-by-pixel basis using the post-classification comparison method and the from-to change matrix is produced, the land use change information obtained.Number of references:15Main heading:Land useControlled terms:Pixels - Planning - Regional planning - Remote sensing - Signal detection - Space opticsUncontrolled terms:Boundary vectors - Change detection - Change detections - Comparison methods - Dynamic changes - Etm+ images - Guangzhou - K-Means - Land use/land cover - Long times - Monitoring changes - Multi temporals - Pearl river deltas - Post-classification - RS datums - Tm images - Unsupervised classificationsClassification code:912.2 Management - 742.2 Photographic Equipment - 741.1 Light/Optics - 731.1 Control Systems - 723.5 Computer Applications - 722.2 Computer Peripheral Equipment - 716.1 Information Theory and Signal Processing - 656.1 Space Flight - 442.2 Land Reclamation - 403.2 Regional Planning and Development - 403 Urban and Regional Planning and DevelopmentDatabase:Compendex

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:A new method to detect infrared single photon using avalanche photodiodes is proposed, which combine the requirements of a single photon detector control circuit and features of the electric pulses generator by transient process of transmission lines. When the terminated boundary conditions of transmission lines are changed quickly, voltage across the switch devices will drop suddenly in the electric pulses generator model and at the same time a signal that can reflect the drive information of the switch device will export from load resistance. So we can replace the switch with avalanche photodiodes who can act as an excellent optoelectronic switch. Then when faint laser pulses enter the avalanche photodiode, resistance of the avalanche photodiode will decrease quickly and with that voltage across avalanche photodiodes will drop simultaneously and

a signal that can reflect the single-photon laser pulses will export from the load resistance. The simulation results are given for the new quenching circuit model of avalanche photodiodes and the analyses emphasis on the feasibility of the quenching model and the influence of each electrical component on the performance of the quenching circuit. Finally optimal parameter of the electrical components in the model is demonstrated.Number of references:16Main heading:Avalanche photodiodesControlled terms:Boundary conditions - Electric lines - Laser pulses - Optoelectronic devices - Quantum cryptography - Switching circuitsUncontrolled terms:Electric pulses generators - Quench circuit - Single photon detection - Transient processClassification code:921 Mathematics - 744.1 Lasers, General - 741.3 Optical Devices and Systems - 716 Telecommunication; Radar, Radio and Television - 714.1 Electron Tubes - 713.4 Pulse Circuits - 706.2 Electric Power Lines and EquipmentTreatment:Theoretical (THR)DOI:10.1117/12.756983Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:The image segmentation is often an important step in the analysis of images. In this paper, an image segmentation method based on cultural algorithms is presented. The method performs the image segmentation by selecting the optimal threshold values. The multi-threshold values are used. First of all, an entropy function corresponding to an image is defined. The optimal threshold values are obtained by making the entropy function reach the maximal value. Secondly, an algorithm based on the principle of cultural algorithms is presented for the computation of the optimal thresholds. The algorithm consists of three major components: a population space, a belief space, and a communication protocol that describes how knowledge is exchanged between the first two components. The designs and implementations of the three components are given in detail. The experimental results show that the segmentation method proposed in this paper can obtain the near optimal threshold for image segmentation.Number of references:12Main heading:Image segmentationControlled terms:Computation theory - Evolutionary algorithms - Image analysis - Optimal systems - Population dynamicsUncontrolled terms:Cultural algorithms - Optimal threshold - Threshold segmentationClassification code:721.1 Computer Theory, Includes Formal Logic, Automata Theory, Switching Theory, Programming Theory - 723.2 Data Processing and Image Processing - 741 Light, Optics and Optical Devices - 961 Systems Science - 971 Social SciencesTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1117/12.791025Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The transverse structures of the IG beams are described by the product of the Ince polynomials and the Gaussian function. Depending on the input power of the beams, the IG beams can be either a soliton state or a breather state. The IG beams constitute the exact and continuous transition modes between Hermite-Gaussian beams and Laguerre-Gaussian beams. The IG vortex beams can be constructed by a linear combination of the even and odd IG beams. The transverse intensity pattern of IG vortex beams consists of elliptic rings, whose number and ellipticity can be controlled, and a phase displaying a number of in-line vortices, each with a unitary topological charge.

Articular cartilage cells of New Zealand white rabbits were suspended in medium with concentration 2% of newborn calf serum. The chondrocytes were treated by LIGL at 1.75, 3.50, 5.25, 7.00 and 8.75 mW/cm² for 5 minutes per day, respectively, for 5 days, and then incubated till the 8th day. The proliferation and collagen synthesis were assessed by a 3-(4, 5-dimenthylthiazol-2-yl)-2, 5-dipheny] tetrazolium bromide (MTT) test and hydroxyproline (Hpr) content measurement, respectively. The MTT tests showed that LIGL irradiation significantly promoted chondrocyte proliferation (P &lt; 0.01), whose optimal intensity was 7.00 mW/cm². The Hpr content tests showed that LIGL irradiation significantly inhibited collagen synthesis (P &lt; 0.01) at the end of the study. The group of 8.75 mW/cm²

was significantly different from groups of 3.50, 5.25 and 7.00 mW/cm² (P &lt; 0.05).

The pumping system is embedded in a finite region and bounded by two particle reservoirs. In the adiabatic limit, we obtain the analytical expressions of the current and the pumping capacity as a function of temperature for normal diffusion, subdiffusion, and

A novel ODC employing surface plasmon polaritons (SPPs) is proposed for high integration. The finite difference time domain (FDTD) method is adopted to simulate and analyze its properties. Results show that the ODC proposed here follows the general regulations of a conventional dielectric ODC, but its transverse size is of nanoscale, which improves the optical integration greatly. For 1550 nm and 1310 nm input wavelengths, when the coupling region length (L) equals half of its coupling length, the Excess Loss is respectively 0.57 dB and 0.56 dB, which is practical in applications. So the research on the present ODC is of some practical importance. &copy; 2008 Science in China Press and Springer-Verlag GmbH.Number of references:15Main heading:Time domain analysis

Abstract:In this paper, we investigate the effect of the boundary of the nonlocal nonlinear medium on the propagation of soliton. On the basic of NNLSE and the Poisson equation, using the Green function approach, we obtain the response function of the lead glass of finite-size, which is a strong nonlocal medium. Starting with the paraxial ray equation, we obtain the analytical solutions of the oscillation trajectory and period of the beam. Comparing the analytical solutions with numerical simulations, we found that our analytical solutions are precise when the point of incidence is not near the boundary of the medium.Number of references:28Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:As a novel hybrid imaging modality, photoacoustic (PA) imaging combines the merits of high optical contrast, good ultrasonic resolution and sufficient imaging depth, which may be of great benefit to noninvasively detect and monitor the pathological changes of subcutaneous vasculature, e.g., congenital vascular tumor and vascular malformation. In this paper, we apply a set of photoacoustic imaging system to image a sample of subcutaneous blood vessels, which is used to simulate the location of human's subcutaneous vasculature. Furthermore, an image of subcutaneous vasculature of the abdomen in a mouse is acquired in vivo. Laser pulses at a wavelength of 532 nm from a Q-switched Nd:YAG laser are employed as light source to generate PA signals in the experiments, because the optical absorption of whole blood is much stronger than that of other tissues at this wavelength. A needle polyvinylidene fluoride (PVDF) hydrophone with a diameter of 1mm is used to capture PA signals through a circular scan. The experimental results show that detailed structural information of subcutaneous vasculature, such as the shape and position of the blood vessels and the vessel branching, is clearly revealed by the PA imaging system. The spatial resolution of the PA imaging system reaches 80&mu;m. Moreover, the reconstructed image of a mouse's abdomen in vivo demonstrates that this technique is suitable for

noninvasive subcutaneous vasculature imaging. All of the results prove that the PA imaging can be used as a helpful tool for monitoring the pathological changes of subcutaneous vasculature.Number of references:16Main heading:Medical imagingControlled terms:Imaging systems - Pathology - Photoacoustic effect - TumorsUncontrolled terms:Photoacoustic imaging - Subcutaneous vasculatureClassification code:461.1 Biomedical Engineering - 461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 741.1 Light/Optics - 746 Imaging Techniques - 751.1 Acoustic WavesTreatment:Experimental (EXP)DOI:10.1117/12.760228Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The numerical results indicate that the higher-order effects can badly distort self-similar parabolic pulse shape and optical spectrum, and at the same time the peak shift and oscillation appear, while the pulse still reveals highly linear chirp but grows into asymmetry. The influence of different higher-order effects on self-similar parabolic pulse propagation has been analysed. It shows that the self-steepening plays a more important role. We can manipulate the geometrical parameters of the microstructured fibre amplifier to gain a suitable dispersion and nonlinearity coefficient which will keep high-quality self-similar parabolic pulse propagation.

Abstract:Considering higher-order dispersion effect, the properties of the self-similar parabolic pulse evolution in a dispersion-decreasing optical fiber with normal group-velocity dispersion arc investigated. The results show that parabolic pulses are distorted and the characteristic of exactly self-similarity will be lost due to the higher-order dispersion. The pulse still reveals highly linear chirp but glows into asymmetric. The highly linear chirp in optical pulse allows for efficient and high-quality pulse compression by use of dispersion compensation technique.Number of references:18Main heading:Optical fibersControlled terms:Dispersion compensation - Fiber optics - Group velocity dispersion - Laser pulses - Light transmission - Nonlinear optics - Pulse compressionUncontrolled terms:Dispersion decreasing fiber - Nonlinear fiber optics - Propagation properties - Self similar pulse - Third order dispersionClassification code:741.1 Light/Optics - 744.1 Lasers, GeneralTreatment:Theoretical (THR)Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 100537, Jena, 07705, GermanyAbstract:We address the physical features exhibited by spatial optical solitons propagating in nonlocal Kerr-type media with Gaussian-shaped response and exponential-decay response, respectively. An iteration algorithm based on the split-step Fourier method is developed to obtain the numerical solutions of the solitons for the nonlocal nonlinear Schro&die;dinger equation with arbitrary degrees of nonlocality. Our numerical results show that the soliton properties in the normalized system are different with the change of the degree of nonlocality and with the different responses. The profiles undergo a gradual and continuous transition from a Gaussian-shaped function in the strongly nonlocal case to a hyperbolic secant function in the local case for the Gaussian-shaped response, but for the exponential-decay response, the soliton profile is not Gaussian-shaped even in the strongly nonlocal cases. For the same response function, the stronger

the nonlocality is, the higher the critical powers for solitons are and the larger of the phase shifts of the solitons. For the same degrees of nonlocality, when the degrees of nonlocality is larger enough, both the critical power and the phase shift for the Gaussian-shaped response are larger than that for the exponential-decay response. &copy; 2007 Elsevier GmbH.

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:To improve the safety of lithium-ion batteries, cresyl diphenyl phosphate (CDP) was used as a flame retardant additive in a LiPF<inf>6</inf> electrolyte solution. The flammability of the electrolytes containing CDP and the electrochemical performances of the cells, LiCoO<inf>2</inf>/Li, graphite/Li and the battery LiCoO<inf>2</inf>/graphite with these electrolytes, were studied by measuring the self-extinguishing time of the electrolytes, the variation of surface temperature of the battery and the charge/discharge curve of the cells or battery. It is found that the addition of CDP to the electrolyte provides a significant suppression in the flammability of the electrolyte and an improvement in the thermal stability of battery. On the other hand, the electrochemical performances of the cells become slightly worse due to the application of CDP in the electrolyte. This alleviated trade-off between the flammability and thermal stability and cell performances provides a possibility to formulate a nonflammable electrolyte by using CDP. &copy; 2008 Elsevier B.V.

The CV and EIS results show that a moderate mechanical dispersion of fumed silica in the H<inf>2</inf>SO<inf>4</inf> solution has important effects on the electrochemical properties of the gelled electrolyte. The optimal mechanical dispersion time is closely related to the operating temperature during preparation of gel, as well as the silica particle size and its distribution. A high stirring rate improves the electrode capacity and decreases the viscosity of the gelled electrolyte. With moderate mechanical dispersion, gelled electrolytes prepared from different fumed silica particles exhibit equal electrode capacities. &copy; 2008 Elsevier B.V.

FTIR analysis was used to identify the relative extent of epoxidation of the samples during the epoxidation reaction. The viscosities of ESO were much higher than that of the raw oil, viscosity increased with degree of epoxidation. The viscous-flow activation energy of ESO was determined to be higher than that of the raw oil (20.72 to 77.93% higher). Thermogravimetry analysis (TG) of ESO was used to investigate the thermodynamic behavior of the samples. With increasing degree of epoxidation, the thermal stability of the samples initially decreased, then increased at the final reacting stage. Differential scanning calorimeter (DSC) indicated that the melting point of ESO was higher than that of soybean oil. Gel permeation chromatography (GPC) indicated the molecular mass of the samples increased initially, then decreased, with an increase in the extent of epoxidation. &copy; 2008 Springer Science+Business Media, LLC.Number of references:16Main heading:Melting pointControlled terms:Activation energy - Chromatographic analysis - Colloids - Differential scanning calorimetry - Digital cameras - Epoxidation - Fourier transform infrared spectroscopy - Gelation - Gravimetric analysis - Hydrodynamics - Laser interferometry - Thermochemistry - Thermodynamic stability - ViscosityUncontrolled terms:Differential scanning calorimeters - DSC - Epoxidation reactions - Epoxidized soybean oil - Epoxidized soybean oils - Flow activation energies - FTIR analyses - GPC - Soybean oils - Structure and properties - Thermal stabilities - Thermogravimetry - Thermogravimetry analysesClassification code:801.4 Physical Chemistry - 802.2 Chemical Reactions - 802.3 Chemical Operations - 921.4 Combinatorial Mathematics, Includes Graph Theory, Set Theory - 931.1 Mechanics - 931.2 Physical Properties of Gases, Liquids and Solids - 931.3 Atomic and Molecular Physics - 941.4 Optical Variables Measurements - 944.6 Temperature Measurements - 801.3 Colloid Chemistry - 631.1 Fluid Flow, General - 631.1.1 Liquid Dynamics - 631.2 Hydrodynamics - 641.1 Thermodynamics - 741.3 Optical Devices and Systems - 742.2 Photographic Equipment - 743.2 Holographic Applications - 744.9 Laser Applications - 801 Chemistry

Box 1139, Collingwood, VIC 3066, AustraliaAbstract:Chlorophyll fluorescence imaging and antioxidative capability in detached leaves of the wild-type Arabidopsis thaliana ecotype Landsberg erecta (Ler) and in three mutants deficient in anthocyanin biosynthesis (tt3, tt4 and tt3tt4) were investigated under photooxidation stress induced by methyl viologen (5&mu;m) in the light. In comparison with the wild-type (WT) plant, photooxidation resulted in significant decreases in the contents of total phenolics and flavonoid, total antioxidative capability and chlorophyll fluorescence parameters (F<inf>v</inf>/F<inf>m</inf>, qP, &Phi;<inf>PSII</inf>, NPQ and ETR) as determined by chlorophyll fluorescence imaging, and in an increase in cell-membrane leakiness in the three anthocyanin mutants. The sequence of sensitivity to photooxidation in the leaves of the four phenotypes were tt3tt4 (deficient in both chalcone synthase locus (CHS) and dihydroflavonol 4-reductase locus (DFR))&gt;tt4 (deficient in CHS)&gt;tt3 (deficient in DFR)&gt;WT. The results demonstrate that anthocyanins might, along with other antioxidants, protect the photosynthetic apparatus against photooxidative damage. An interesting phenomenon was observed over the

270min of the photooxidative treatment, that is, fluorescence imaging revealed that qP, &Phi;<inf>PSII</inf> and ETR appeared in three phases (fall &rarr partial recovery &rarr rapid fall). This was considered to be a modulation of reversible deactivation in PSII to cope with the moderate oxidative stress in the first two stages of short-term treatment (&lt;150min), followed finally by damage to PSII under severe oxidative stress with prolonged treatment. &copy; CSIRO 2008.Number of references:41Main heading:Light emissionControlled terms:Biochemical engineering - Biochemistry - Chlorophyll - Fluorescence - Luminescence - Phenols - Photooxidation - Photoresists - Plants (botany) - PorphyrinsUncontrolled terms:Anthocyanin biosynthesis - Arabidopsis - Arabidopsis thaliana - Chlorophyll fluorescence - Chlorophyll fluorescence imaging - Enhanced sensitivity - Flavonoid - Fluorescence imaging - Methyl viologen - Reversible deactivation of PSII - Stress induced - Total phenolics - Wild-typeClassification code:461.9 Biology - 714.2 Semiconductor Devices and Integrated Circuits - 741.1 Light/Optics - 801.2 Biochemistry - 804.1 Organic Compounds - 805.1.1 Biochemical EngineeringDOI:10.1071/FP08069Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The self-similar amplitude function, phase function, strict linear chirp function and effective temporal pulse width are given in the paper. The results show that self-similar pulses still have linear chirp and remarkable third-order dispersion effect.

Under an appropriate configuration, a true non-Abelian gauge potential naturally arises in connection with the geometric phase associated with two degenerated dark states in a four-state atomic system interacting with three pulsed laser fields. We show that the population in the atomic state at the end of a composed path formed by two closed loops C<inf>1</inf> and C<inf>2</inf> in the parameter space can be significantly different from the composed counter-ordered path. This population difference is directly induced by the noncommutative feature of non-Abelian geometric phases and can be detected unambiguously with current technology. &copy; IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.Number of references:41Main heading:IonsControlled terms:Atomic physics - Atoms - Electrolysis - Gages - Geometry - Pulsed laser applications - Pulsed laser depositionUncontrolled terms:Atomic states - Atomic systems - Closed loops - dark states - Geometric phase - Geometric phases - Non-Abelian gauge - Pulsed laser fields - Trapped ionsClassification code:744.9 Laser Applications - 801 Chemistry - 801.4.1 Electrochemistry - 921 Mathematics - 931.3 Atomic and Molecular Physics - 943.3 Special Purpose InstrumentsDOI:10.1088/1367-2630/10/4/043031Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Photodynamic therapy (PDT) employing photosensiter N-aspartyl chlorin e6 (NPe6) can induce lysosome disruption and initiate the intrinsic apoptotic pathway. Bax, a member of the Bcl-2 family of proteins, is an essential regulator of apoptosis. Bax is normally found in the cytosol of healthy cells, and translocates to mitochondria in response to many apoptotic stimuli. In this study, using real-time single-cell analysis, we have investigated the kinetics of Bax distribution during NPe6-induced apoptosis in ASTC-a-1 cells. In order to monitor Bax subcellular distribution, cells were stained with GFP-Bax and Mito Tracker Red. The results show that Bax redistribution occurred at about 170 min after treated with NPe6-PDT, and then sequestered into clusters associated with the mitochondira within 30 min. Our data clearly showed the spatial and temporal changes in Bax distribution in living cells during NPe6-induced apoptosis.Number of references:17Main heading:Cell deathControlled terms:Mitochondria - Photodynamic therapy - Photosensitizers - ProteinsUncontrolled terms:Bax distribution - N-aspartyl chlorin e6 (NPe6)Classification code:461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 461.9 Biology - 741.1 Light/Optics - 804.1 Organic CompoundsTreatment:Theoretical (THR)DOI:10.1117/12.762026Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Meanwhile, many kinds of Virtual Learning Environments (VLEs), such as WebCT, BlackBoard, and WebCL are emerging in the field of Chinese Higher Education in the past decade for serving this new model. How do Chinese students think about this new approach? There is no much research addressed on it. We design a small-scale research for examining students' perceptions of blended learning, which is based upon an undergraduate course offered at School of Information Technology in Education in South China Normal University. 20 students registered in the course. The findings of this study reveal that students' understandings of blended learning are formed through the course, and their attitudes toward it are positive. &copy; 2008 Springer-Verlag Berlin Heidelberg.

Eng. Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United StatesAbstract:Bounded Model Checking (BMC) has played an important role in verification of software, embedded systems and protocols. The idea of BMC is to encode Finite State Machine (FSM) and Linear Temporal Logic (LTL) verification specification into satisfiability (SAT) instances, and then to search for a counterexample via various SAT tools. Improving encoding technology of BMC can generate a SAT instance easy to solve, and therefore is essential to improve the efficiency of BMC. In this paper, we improve the encoding of BMC by combining the characteristic of FSM state transition and semantics of LTL, get a simple and efficient recursion formula which is useful to efficiently generate SAT instances. We present an efficient algorithm to encode the modal operator (safety formula) in BMC. The experiments for comparative analysis shows that this encoding algorithm is more powerful than the existing two mainstream encoding algorithms in both the scale of generated SAT instances and the solving efficiency. The methodology presented in this paper is also valuable for optimization of other modal operator encodings in BMC. &copy; 2008 IEEE.Number of references:17Main heading:Boolean functionsControlled terms:Computer networks - Computer software selection and evaluation - Embedded systems - Information theory - Integrated circuits - Machine tools - Mathematical operators - Model checking - Software engineering - Temporal logic - Verification

Abstract:The decoherence of two initially entangled qubits in non-Markovian reservoirs has been investigated exactly without Born-Markovian approximation or rotating-wave approximation (RWA). The nonperturbative quantum master equation is derived and its exact solution is obtained. The decoherence behavior of two qubits, initially entangled in Bell states, has been investigated in the weak coupling regime and strong coupling regime. The results show that the counter-rotating wave terms have obvious influence on the decoherence behavior in the non-Markovian regime. &copy; 2008 The American Physical Society.Number of references:25Main heading:RotationControlled terms:Polynomial approximationUncontrolled terms:Bell states - Decoherence - Entangled qubits - Exact solutions - Markovian - Markovian approximations - Nonperturbative - Quantum master equations - Rotating waves - Strong couplings - Wave approximations - Weak couplingsClassification code:601.1 Mechanical Devices - 921.6 Numerical Methods - 931.1 MechanicsDOI:10.1103/PhysRevA.78.062318Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 101161, Weinheim, D-69451, GermanyAbstract:The iron trifluorophosphane complexes [Fe(PF<inf>3</inf>)<inf>n</inf>] (n = 4, 5), [Fe<inf>2</inf>-(PF<inf>3</inf>)<inf>n</inf>] (n = 8, 9), [H

<inf>2</inf>Fe(PF<inf>3</inf>)<inf>4</inf>], and [Fe<inf>2</inf>(PF <inf>2</inf>)<inf>2</inf>(PF<inf>3</inf>)<inf>6</inf>] have been studied by density functional theory. The lowest energy structures of [Fe(PF <inf>3</inf>)<inf>4</inf>] and [Fe-(PF<inf>3</inf>)<inf>5</inf>] are a triplet tetrahedron and a singlet trigonal bipyramid, respectively. Both cis and trans octahedral structures were found for [H<inf>2</inf>Fe(PF<inf>3</inf>) <inf>4</inf>] with the cis isomer lying lower in energy by &asyum; 10 kcal mol ^-1. The lowest energy structure for [Fe<inf>2</inf>(PF <inf>3</inf>)<inf>8</inf>] has two [Fe-(PF<inf>3</inf>)<inf>4</inf>] units linked only by an iron-iron bond of length 2.505 A&ring; consistent with the formal Fe=Fe double bond required to give both iron atoms the favored 18-electron configuration. In the lowest energy structure for [Fe <inf>2</inf>(PF<inf>3</inf>)<inf>4</inf>] one of the iron atoms has inserted into a P-F bond of one of the PF<inf>3</inf> ligands to give a structure [(F<inf>3</inf>P)<inf>4</inf>Fe &larr;-PF<inf>2</inf>Fe(F)(PF<inf>3</inf>) <inf>4</inf>] with a bridging PF<inf>2</inf> group and a direct Fe-F bond. A bridging PF<inf>3</inf> group is found in a considerably higher energy [Fe <inf>2</inf>(PF<inf>3</inf>)<inf>9</inf>] structure at &asyum; 30 kcal mol ^-1 above the global minimum. However, this bridging PF<inf>3</inf> group keeps the two iron atoms too far apart (&asyum; 4 A&ring;) for the direct iron-iron bond required to give the iron atoms the favored 18-electron configuration. The preferred structure for [Fe<inf>2</inf>(PF<inf>2</inf>) <inf>2</inf>(PF<inf>3</inf>)<inf>6</inf>] has a bridging PF<inf>2</inf> group, as expected. However, this bridging PF<inf>2</inf> group bonds to one of the iron atoms through an P-Fe covalent bond and to the other iron through an F&rarrFe dative bond, leaving an uncomplexed phosphorus lone pair. &copy; 2008 Wiley-VCH Verlag GmbH &amp; Co.

The pulses which are discarded in the phase coding scheme can be coded in time coding, so the useful bit rate in the present scheme can be doubled. At the same time, the phase coding keys and the time coding keys are obtained. We can use one group of keys to communicate and the other one to guard against eavesdropping, or combine both of them to form new keys.

The WDM-PON based on the amplified spontaneous emission (ASE) injected wavelength-locked Fabry-Perot (F-P) laser diodes has gained great attention because of its cost effectiveness and color-free operation. The gain, side-mode suppression ratio (SMSR) and relative intensity noise (R1N) of the wavelength-locked F-P laser diode (LD) have been studied experimentally. And the relationship between injection current and the reflectivity of front facet of F-P LD, for a given ASE and gain, has been studied theoretically and experimentally. The best RIN and SMSR can be got with the injection current which is 1.3-1.7 times of threshold current. And there is an optimum front facet for a given ASE injection power and gain with the smallest injection current.Number of references:10Main heading:Wavelength division multiplexingControlled terms:Broadband networks - Computer networks - Cost effectiveness - Diodes - Fabry-Perot interferometers - Fiber optic networks - Ladder networks - Lasers - Optical data processing - Spontaneous emissionUncontrolled terms:Injection currents - Optical fiber communication - Passive optical network - Semiconductor laser - Wavelength-lockedClassification code:941.3 Optical Instruments - 723 Computer Software, Data Handling and Applications - 723.2 Data Processing and Image Processing - 741.1.2 Fiber Optics - 741.3 Optical Devices and Systems - 744.1 Lasers, General - 911.2 Industrial Economics - 912.2 Management - 912.3 Operations Research - 722 Computer Systems and Equipment - 703.1 Electric Networks - 703.2 Electric Filters - 711 Electromagnetic Waves - 718 Telephone Systems and Related Technologies; Line Communications - 714.1 Electron Tubes - 716 Telecommunication; Radar, Radio and Television - 717 Optical Communication - 714.2 Semiconductor Devices and Integrated

The results indicated that DHA effectively inhibited the proliferation of ASTC-a-1 cells via a concentration-dependent manner. Dose-dependent activation of caspase-3 was determined during the DHA-induced apoptosis. The decreased FRET efficiency was in response to the increased caspase-3 activities in DHA-treated cells. The report has proved, for the first time, that FRET efficiency is an appropriate method that can be used as a real time quantitative measurement of DHA-induced activation of caspase-3 in living cells.Number of references:8Main heading:CellsControlled terms:Cell death - Concentration (process) - Cytology - Emission spectroscopyUncontrolled terms:Caspase-3 - Caspase-3 activation - Cell apoptosis - Dihydroartemisinin(DHA) - Donor-acceptor pair - Dose-dependent - Emission spectrums - Fluorescence emission spectra - Fluorescence resonance energy transfer (FRET) - Induced apoptosis - Living cells - Novel methods - Quantitative measurements - Real timeClassification code:461.2 Biological Materials and Tissue Engineering - 461.9 Biology - 741.1

In this paper, a practical non-orthogonal decoy state protocol with a heralded single photon source (HSPS) for QKD is presented. The protocol is based on 4 states with different intensities, i.e. one signal state and three decoy states. The signal state is for generating keys; the decoy states are for detecting the eavesdropping and estimating the fraction of single-photon and two-photon pulses. We have discussed three cases of this protocol, i.e. the general case, the optimal case and the special case. Moreover, the final key rate over transmission distance is simulated. For the low dark count of the HSPS and the utilization of the two-photon pulses, our protocol has a higher key rate and a longer transmission distance than any other decoy state protocol. &copy; 2008 Chin.

Photoacoustic signals carry the information of the light absorption distribution of biological tissue, which is often related to its character of structure, physiological and pathological changes because of different physiology conditions in response to different light absorption coefficients. A non-invasive PAI system was developed and successfully acquired in vivo images of mouse brain. Based on the intrinsic PA signals from the brain, the vascular network and the detailed structures of the mouse cerebral cortex were clearly visualized. The ability of PAI monitoring of cerebral hemodynamics was also demonstrated by mapping of the mouse superficial cortex with and without drug stimulation. The extracted PA signals intensity profiles obviously testified that the cerebral blood flow (CBF) in the mouse brain was changed under the stimulation of acetazolamide (ACZ). The experimental results suggest that PAI can provide non-invasive images of blood flow changes, and has the potential for brain function detection.Number of references:15Main heading:Imaging techniquesControlled terms:Blood - Drug products - Hemodynamics - Noninvasive medical procedures - Photoacoustic effect - TissueUncontrolled terms:Cerebral blood flow - Drug stimulation - Non-invasive photoacoustic imaging technology - Ultrasonic resolutionClassification code:461.1 Biomedical Engineering - 461.2 Biological Materials and Tissue

Publisher:American Institute of Physics, 2 Huntington Quadrangle, Suite N101, Melville, NY 11747-4502, United StatesAbstract:The switching speed of magnetic fluids was investigated by using laser light of different power densities as well as incandescent light. It was found that the switching speed exhibited a strong dependence on incident power density and there existed an optimum value at which the fastest switching operation was achieved. In addition, it was revealed that the clustering of magnetic nanoparticles, which became resolved at large power densities, resulted in a rapid agglomeration of nanoparticles when a magnetic field was applied. It is suggested that the optical trapping force of the laser beam is responsible for the formation of clusters. &copy; 2008 American Institute of Physics.Number of references:28Main heading:Magnetic materialsControlled terms:Agglomeration - Coagulation - Flow of solids - Fluids - Laser beams - Lasers - Magnetic fields - Magnetic fluids - Magnetism - Nanoparticles - Nanostructured materials - Nanostructures - Optical engineering - Pulsed laser deposition - SwitchingUncontrolled terms:American Institute of Physics (AIP) - Applied (CO) - Incident power - Large power - Laser light - Laser-induced - Magnetic (CE) - Magnetic nanoparticles (MNP's) - Optical trapping force - Optimum value - Power density (PD) - Switching operations - Switching speedsClassification code:802.3 Chemical Operations - 761 Nanotechnology - 744.9 Laser Applications - 744.8 Laser Beam Interactions - 931.1 Mechanics - 744.1 Lasers, General - 721.1 Computer Theory, Includes Formal Logic, Automata Theory, Switching Theory, Programming Theory - 708.4 Magnetic Materials - 701.2 Magnetism: Basic Concepts and Phenomena - 741 Light, Optics and Optical DevicesDOI:10.1063/1.2942388Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Fluorescence correlation spectroscopy (FCS) is a new kind of real-time, high-speed and single-molecule technique. It is used to detect the kinetic characteristics of fluorescent dye such as diffusion coefficient in the aqueous solution. Combined with confocal microscope optics, it has been now widely applied in cell biological research. Through a time correlation analysis of spontaneous intensity fluctuations, this technique with EGFP as a probe is capable of determining viscosity of fluids according to Stokes-Einstein equation. Nucleoplasms viscosity is an important physical parameter to quantify the rheological characteristics of the nucleoplasm. Investigation on nucleoplasmic viscosity plays an important role in further understanding intranuclear environment. In this paper, FCS is introduced to noninvasively investigate nucleoplasmic viscosity of living cells. The results show that nucleoplasmic viscosity of lung adenocarcinoma (ASTC-a-1) cells is 2.55&plusmn;0.61 cP and nucleoplasmic viscosity is larger than cytoplasmic viscosity at 37&deg;C (pH 7.4). In addition, significant changes in nucleoplasmic viscosity are detected by FCS when cells are exposed to hyper or hypotonic medium. Our study suggests that FCS can be used to detect the kinetic characteristics of biomolecules in living cells and thus helps to investigate the dynamic changes of the microenvironment in the cell.Number of references:28Main heading:Fluorescence spectroscopyControlled terms:Cells - Confocal microscopy - Optical correlation - Solutions - ViscosityUncontrolled terms:Cytoplasmic viscosity - Fluorescence correlation spectroscopy (FCS) - Hypertonic medium - Nucleoplasmic viscosityClassification code:941.4 Optical Variables Measurements - 941.3 Optical Instruments - 803 Chemical Agents and Basic Industrial Chemicals - 744.9 Laser Applications - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 461.2 Biological Materials and Tissue EngineeringTreatment:Experimental (EXP)DOI:10.1117/12.760226Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

CCK-8 was used to assay the inhibition of taxol on the cells viability. Cell viability was inhibited obviously 24 h after taxol treatment. Confocal fluorescence scanning microscope was used to monitor the morphology changes in cells with taxol treatment. Fluorescence resonance energy transfer (FRET) and acceptor photobleaching techniques were used to analyze the caspase-3 activation in the taxol-induced cell swelling and cell dearth. Taxol induced cell swelling, cytoplasmatic vacuolization and cell death without cell shrinkage, an apoptotic feature, and membrane rupture, a necrotic feature. The emission spectra of scat3 inside living cells expressed stably with scat3 were the same for control (without taxol). Further analysis with FRET and acceptor photobleaching techniques showed that the caspase-3 was not activated by taxol for the cytoplastic vacuoliazation cells expressed stably with scat3 plasmid, suggesting that caspase-3 is not involved in the taxol-inducecd cell swelling, cytoplasmatic vacuolization and cell death. These results show that taxol can induce a novel nonapoptotic PCD resembling the paraptosis in ASTC-a-1 cells.Number of references:23Main heading:CellsControlled terms:Activation analysis - Cell death - Cell membranes - Cytology - Emission spectroscopy - Energy transfer - Fluorescence - Light emission - Luminescence - Photobleaching - ResonanceUncontrolled terms:Caspsae-3 - Fluorescence resonance energy transfer (FRET) - Fluorescence spectra - Paraptosis - Taxol (paclitaxel)Classification code:931.1 Mechanics - 801 Chemistry - 751.1 Acoustic Waves - 741.1 Light/Optics - 931.3 Atomic and Molecular Physics - 701 Electricity and Magnetism - 525.4 Energy Losses (industrial and residential) - 461.9 Biology - 461.2 Biological Materials and Tissue Engineering - 641.2 Heat TransferDOI:10.3964/j.issn.1000-0593(2008)11-2623-05Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

In the present paper, differential diagnosis of superficial human bladder cancer was studied using the diffuse reflectance spectral ratio (R540/R575) of the oxygenated hemoglobin absorption bands at 540 and 575 nm in vitro. Diffuse reflectance spectra for mucosa/submucosa tissues of normal bladder and superficial bladder cancer were measured using a spectrophotometer with an integrating sphere attachment. The results of measurement showed that there were three the diffuse reflectance spectral dips at 415, 542 and 577 nm respectively for mucosa/submucosa tissues of normal bladder and superficial bladder cancer in the spectral range from 400 to 600 nm. The mean diffuse reflectance spectral ratio (R540/R575) of normal bladder mucosa/submucosa tissue decreased slowly with time increase after surgical excision, and the mean diffuse reflectance spectral ratio (R540/R575) of superficial bladder cancer mucosa/submucosa tissue also decreased slowly with time increasing after surgical excision. The mean diffuse reflectance spectral ratios (R540/R575) of normal bladder mucosa/submucosa tissue were 111%, 107%, 104% and 102% after 2, 3, 4 and 5 h after surgical excision respectively, and those of superficial bladder cancer mucosa/submucosa tissue were 98.4%, 95.5%, 93.1% and 91.6% after 2, 3, 4 and 5 h after surgical excision respectively. There were significant differences in mean diffuse reflectance spectral ratio (R540/R575) for mucosa/submucosa tissues between normal bladder and superficial bladder cancer after 2, 3, 4 and 5 h after surgical excision respectively (p &lt; 0.05). Differences in mean diffuse reflectance spectral ratio (R540/R575) for

mucosa/submucosa tissues between normal bladder and superficial bladder cancer were 12.6%, 11.5%, 10.9% and 10.4% after 2, 3, 4 and 5 h after surgical excision respectively. It is obvious that pathological changes in bladder mucosa/submucosa tissues induced changes in the component and structure of the tissues, and especially quantitative changes in oxyhemoglobin and de-oxyhemoglobin of tissues obviously. Conclusion of the study provides a new method that can be applied to rapid, low-cost and noninvasive optical biopsy of superficial bladder cancer.Number of references:22Main heading:TissueControlled terms:Absorption - Absorption spectroscopy - Biopsy - Diagnosis - Earthquake effects - Hemoglobin - Histology - ReflectionUncontrolled terms:Absorption bands - Bladder cancers - Differential diagnoses - Diffuse reflectance spectral ratio (R540/R575) - Diffuse reflectance spectroscopy - Diffuse reflectance spectrums - Diffuse reflectances - Early diagnoses - Human bladder cancers - In vitro - Integrating spheres - Malignant lesions - Noninvasive methods - Noninvasive optical biopsies - Optical biopsies - Oxygenated hemoglobins - Pathological changes - Quantitative changes - Spectral dips - Spectral ranges - Spectral ratios - Superficial bladder cancer diagnosis - Surgical excisionsClassification code:941.4 Optical Variables Measurements - 741.1 Light/Optics - 801 Chemistry - 802.3 Chemical Operations - 804 Chemical Products Generally - 931.2 Physical Properties of Gases, Liquids and Solids - 941.3 Optical Instruments - 741 Light, Optics and Optical Devices - 484 Seismology - 461.9 Biology - 461.6 Medicine and Pharmacology - 461.2 Biological Materials and Tissue Engineering - 408.1 Structural Design, General - 711 Electromagnetic WavesDOI:10.3964/j.issn.1000-0593(2008)11-2721-05Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Therefore, the conventional definition of internal quantum efficiency should be revised as pointed out by other researchers. In this work, some more detailed considerations of photon extraction efficiency in LEDs are examined using a simple slab structure. Theoretical modeling results show that in order to improve the overall light conversion efficiency, it is necessary to remove the device substrate, to optimize the overall doping profile design, and to use highly reflective metal contacts or DBR structures.Number of references:8Main heading:ExtractionControlled terms:Conversion efficiency - Diodes - Light emission - Light emitting diodes - Light sources - Lighting - Metal recovery - Photons - Physical optics - Recycling - Renewable energy resources - Solar energy - Solar radiation - Structural metals

These features make it suitable for detecting the pathological changes of subcutaneous vasculature. A setup of photoacoustic imaging system was employed to achieve images of subcutaneous vasculature and subcutaneous tumor-related vascular anomalies in mice in vivo. The networks of subcutaneous vasculature are clearly identified in the photoacoustic images, blood vessels which are invisible to the naked eye under the skin surface and tumor-related abnormal vasculature are also revealed by the photoacoustic system. Moreover, micro blood vessels correlated with the high frequency signals become evident after digital image processing based on high-pass filtering. This work demonstrates that photoacoustic imaging could potentially provide a valuable tool for monitoring the pathological changes of subcutaneous vasculature in early stage. &copy; 2008 EDP Sciences.Number of references:24Main heading:PathologyControlled terms:Blood vessels - Image resolution - Optical correlation - Photoacoustic effect - Rats - Ultrasonic wavesUncontrolled terms:Imaging depth - Optical contrast - Photoacoustic imaging - Ultrasonic resolutionClassification code:461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 461.8 Biotechnology - 741.1 Light/Optics - 751.1 Acoustic Waves - 753.1 Ultrasonic WavesTreatment:Theoretical (THR)DOI:10.1051/epjap:2008016Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Hemoglobin was obtained from the healthy adult. The results show that the intensity ratio of the oxyhemoglobin marker band 570 cm^-1 to the aquomethemoglobin marker band 495 cm^-1, and that of low spin state marker band 1586 cm^-1 to the high spin state marker band 1555 cm^-1 decrease during the interaction. The bands sensitive to the oxidation state shift to higher frequency. This work indicates that micro-Raman spectroscopy could monitor the bioeffects of sodium nitrite on the oxyhemoglobin, and distinguish hemoglobin and aquomethemoglobin.

The convergence and the optimal parameters for the method are studied when the iteration parameters satisfy some relationship. Theoretical analyses show that the UBOR-type method has faster asymptotic convergence rate than the SOR-like method and its convergence rate can reach the same as that of the GSOR method at least. Numerical experiments

support our theoretical results. Moveover, the numerical results further reveal that the new method can be much more effective than the GSOR method in terms of iteration steps. &copy; 2008 Elsevier Inc.

The surface morphology, composition, surface distributions of alloy elements, and lithium intercalation/de-intercalation behaviors of the fabricated films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), electron probe microanalyzer (EPMA), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma atomic emission spectrometry (ICP), cyclic

voltammetry (CV), and galvanostatic charge/discharge (GC) measurements. It is found that the lithium intercalation/de-intercalation behavior of the Sn film can be significantly improved by its composite with graphite. With cycling, the discharge capacity of the Sn film without composite changes from 570 mAh/g of the 2nd cycle to 270 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 90% and 95%. Nevertheless, the discharge capacity of the composite Sn/C film changes from 575 mAh/g of the 2nd cycle to 515 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 95% and 100%. The performance improvement of tin by its composite with graphite is ascribed to the retardation of the bulk tin cracking from volume change during lithium intercalation and de-intercalation, which leads to the pulverization of tin. &copy; 2008 The Nonferrous Metals Society of China.Number of references:13Main heading:TinControlled terms:Atomic spectroscopy - Carbon - Composite films - Composite materials - Copper - Cyclic voltammetry - Discharge (fluid mechanics) - Emission spectroscopy - Fabrication - Graphite - Inductively coupled plasma - Lithium - Lithium alloys - Magnetron sputtering - Magnetrons - Metal cladding - Microscopic examination - Photoelectron spectroscopy - Photoresists - Thick films - Titanium compounds - X ray analysis - X ray photoelectron spectroscopyUncontrolled terms:Alloy elements - Charge/discharge - Cu foils - Discharge capacities - Electron probes - Galvanostatic - Inductively coupled plasma atomic emission spectrometries - Intercalation behaviors - Lithium intercalations - Microanalyzer - Performance improvements - Surface distributions - TiN films - Volume changes - X-ray diffractions - X-ray photoelectron spectroscopiesClassification code:745.1 Printing - 812.2 Refractories - 811 Cellulose, Paper and Wood Products - 804.2 Inorganic Compounds - 804.1 Organic Compounds - 804 Chemical Products Generally - 801.4.1 Electrochemistry - 801 Chemistry - 746 Imaging Techniques - 813.1 Coating Techniques - 951 Materials Science - 942.2 Electric Variables Measurements - 932.3 Plasma Physics - 813.2 Coating Materials - 932.1 High Energy Physics - 913.4 Manufacturing - 817.1 Polymer Products - 931.3 Atomic and Molecular Physics - 741.3 Optical Devices and Systems - 407 Maritime and Port Structures; Rivers and Other Waterways - 542.4 Lithium and Alloys - 539.3 Metal Plating - 538.2 Welding - 535.1 Metal Rolling - 482.2 Minerals - 444.1 Surface Water - 421 Strength of Building Materials; Mechanical Properties - 415 Metals, Plastics, Wood and Other Structural Materials - 544.1 Copper - 741.1 Light/Optics - 715.1 Electronic Equipment, non-communication - 714.2 Semiconductor Devices and Integrated Circuits - 546.2 Tin and Alloys - 714.1 Electron Tubes - 631.1.1 Liquid Dynamics - 549.1 Alkali Metals - 712.1 Semiconducting MaterialsDOI:10.1016/S1001-0521(08)60171-0Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:Taxol (Paclitaxel), an isolated component from the bark of the Pacific yew Taxus brevifolia, exhibits a broad spectrum of clinical activity against human cancers. Taxol can promote microtubule (MT) assembly, inhibit depolymerization, and change MT dynamics, resulting in disruption of the normal reorganization of the microtubule network required for mitosis and cell proliferation. However, the molecular mechanism of taxol-induced cell death is still unclear. In this report, CCK-8 was used to assay the inhibition of taxol on the human lung adenocarcinoma (ASTC-a-1) cells viability, confocal fluorescence microscope was used to monitor the morphology changes of cells with taxol treatment. We for the first time describe the characteristics of taxol-induced cells swelling, cytoplasmic vacuolization and cell death. Taxol induced swelling, cytoplasmatic vacuolization and cell death without cell shrinkage and membrane rupture. These features differ from those of apoptosis and resemble the paraptosis, a novel nonapoptotic PCD.Number of references:26Main heading:Cell deathControlled terms:Cell proliferation - Confocal microscopy - Depolymerization - Fluorescence - Fluorescence microscopy - Image analysis - Swelling - TumorsUncontrolled terms:Laser confocal fluorescence microscopes - Paraptosis - Taxol - VacuolizationClassification code:951 Materials Science - 941.3 Optical Instruments - 931.4 Quantum Theory; Quantum Mechanics - 815.2 Polymerization - 744.9 Laser Applications - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 461.9 Biology - 461.2 Biological Materials and Tissue EngineeringTreatment:Theoretical (THR); Experimental (EXP)

Examination of these fossils revealed 11 species belonging to 8 families and 10 genera. They can be classified as: (1) assemblage of Gyraulus and Galba mainly consisting of Gyraulus convexiusculus, Gyraulus sibiricus, Galba pervia and Galba superegra Gredler, etc. (2) assemblage of Vallonia mainly consisting of terrestrial snails, such as Vallonia patens, Pupilla muscorum and Discus paupe, etc. Based on the dating results, and the living habits, living conditions, and geographic distribution of their extant species, we suggest that: the ages of 33LS, 35LS, 37FL, and 39LS are 26000, 29000, 33000 and 38000 a, respectively, corresponding well to the interstadial period in GRIP 4, 5, 6 and 10 in terms of chronology and climatic characters; 33LS, 35LS and 39LS represent very warm-humid periods, while 37FL represents a less warm-humid period; the four periods of climatic fluctuations recorded in MGS3 were related to the strong impact of the summer monsoon in East Asia in Mu

It is found that the redox process of ferrocene in solution is controlled by diffusion and surface electrochemical steps on the MWNT/GC electrode in contrast to the diffusion-controlled process of ferrocene on the GC electrode. The adsorbed ferrocene exhibits a pair of well-defined redox waves in the potential range from - 0.2&nbsp;V to 0.6&nbsp;V.

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:Enrofloxacin (ENR) is a fluoroquinolone developed exclusively for the use in veterinary practice for the treatment of respiratory and gastrointestinal infections, and ciprofloxacin (CIP) is its main active metabolite. Their contents are regulated by the EU Council Regulation no. 2377/90 in animal edible tissues. We developed a sensitive and rapid method for the determination of ENR and CIP by capillary electrophoresis (CE) with electrochemiluminescence (ECL) detection. The method is based on the detection of aliphatic tertiary or secondary amino moieties in ENR and CIP with end-column tris(2,2-bipyridyl)ruthenium(II) electrochemiluminescence. Parameters that affect separation and detection were optimized. Under the optimized conditions, the calibration functions were linear in the range of 0.03-1 &mu;g ml^-1 for ENR and 0.05-1.2 &mu;g ml^-1 for CIP. The detection limits of ENR and CIR were 10 ng ml^-1 and 15 ng ml^-1, respectively, based on the signal-to-noise ratio of

Yet

the precise signal transduction pathway(s) which regulates AIF-induced apoptotic pathway still remains poorly understood. In this study, we investigated the molecular mechanism of AIF release and redistribution in cisplatin-induced apoptosis in living ASTC-a-1 cells, as assessed by real-time anlysis. Herein, We report that during cisplatin-induced apoptosis, calpain activation, as measured in intact cells by a fluorescent substrates, is an early event, taking place well before AIF release and caspase-3 activation. Confocal imaging of the cells transfected with AIF-GFP demonstrated that AIF release occurred about 9 h after cisplatin treatment. The event proceeded progressively over time, coinciding with a nuclear translocation and lasting for more than 2 hours. AIF release and redistribution were effectively inhibited in samples co-treated with calpeptin and PD150606, two selective calpain inhibitors. Therefore, our results clearly show the kinetics of AIF release and redistribution in cisplatin-induced apoptosis in living ASTC-a-1 cells, and calpain played a crucial role in these events.Number of references:21Main heading:MitochondriaControlled terms:Cell death - Molecular mechanics - Real time control - Signal transductionUncontrolled terms:Calpain - Cisplatin - Real-time single-cell analysisClassification code:461.2 Biological Materials and Tissue Engineering - 461.9 Biology - 731 Automatic Control Principles and Applications - 931.1 Mechanics - 931.3 Atomic and Molecular PhysicsTreatment:Experimental (EXP)DOI:10.1117/12.760234Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

As for the first example, Y<inf>2</inf>O<inf>3</inf>:Eu³⁺@SiO<inf>2</inf>@YVO <inf>4</inf>:Eu³⁺, its synthetic route, structure and optical properties are presented in this paper. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HR-TEM), energy-dispersive x-ray spectra (EDS) and photoluminescence (PL) were all employed to characterize the composite core-shell phosphors. The XRD, FE-SEM and HR-TEM results indicate that the SiO<inf>2</inf> and YVO <inf>4</inf>:Eu³⁺ layers have been successfully coated on Y <inf>2</inf>O<inf>3</inf>:Eu³⁺ nanoparticles and SiO<inf>2</inf> layer, respectively: these layers were further verified by the EDS. The PL showed that the red-emitting phosphor Y<inf>2</inf>O<inf>3</inf>:Eu ³⁺@SiO<inf>2</inf>@YVO<inf>4</inf>:Eu³⁺ possessed the independent luminescent properties of both the core Y<inf>2</inf>O <inf>3</inf>:Eu³⁺ and the shell YVO<inf>4</inf>:Eu³⁺. The emissions were dominated by ⁵D<inf>0</inf> &rarr ⁷F <inf>1</inf> or ⁵D<inf>0</inf> &rarr ⁷F<inf>2</inf> transitions of Eu³⁺ when excited with different wavelengths. Since this broad-band response to excitation in the range of 225-340 nm gave more red/dark red emissions found at 612, 616 and 620 nm, the novel phosphor Y <inf>2</inf>O<inf>3</inf>:Eu³⁺@SiO<inf>2</inf>@YVO <inf>4</inf>:Eu³⁺ could have potential biological labeling applications with wide flexibility. &copy; IOP Publishing Ltd.

Two different types of baseline methods: Autoslope and extended, were discussed and the results show that the baseline values will change with the baseline methods. Experiments of three samples also testify that the larger the baseline values are, the smaller the effective diameter and the polydispersity are. The reason that the results measured by autoslope ate more stable than those measured by extended was analyzed.Number of references:8

Box 211, Amsterdam, 1000 AE, NetherlandsAbstract:Based on more realistic physics we study the phonon spectra of the Fibonacci chain by taking into account a nonlinear resistance. It is found that the nonlinear force should be very weak and consequently, the continuity, range and gaps of the phonon spectra would be still controlled dominantly by the relative strength of spring constants and chain length. It means that even if no additional nonlinear resistance was taken into account, the conventional results of phonon spectra are exactly correct. On the other hand, in the framework of a conventional model we investigated the relationship between the biggest gaps of phonon spectra and defects of Fibonacci-like aperiodic chains. By means of numerical calculations one can obtain quantitatively the maximum of the length of a one-dimensional aperiodic chain sensitive to boundaries. This method would be useful for the calculation of quasiperiodic and aperiodic lattices. &copy; 2008 Elsevier B.V. All rights reserved.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:High spatial resolution remote sensing images are playing an increasing important role in various applications in the world. As the fundamental work, classification of remote sensing is significant in the applications. This paper proposed a new feature extraction approach based on the shape adaptive neighborhood (SAN) for the classification of high spatial resolution remote sensing images. The heterogeneity based on the color characteristics was employed to determine the SAN of each pixel. Then all the color features, texture features and shape features were extracted from each SAN, and were fused by the feature level data fusion methods to the final feature space of the RS image. Then the features were used to do the classification work. As the experiment results shown, the total precision of the classification was 0.9187, and the kappa coefficient was 0.7950. By analyzing different maximum size of the SAN and different threshold of the heterogeneity, the best maximum size of the SAN was 11*11 for the study area and the most suitable threshold was 0.5. &copy; 2008 SPIE.Number of references:12Main heading:Feature extractionControlled terms:Color - Data processing - Image reconstruction - Image resolution - Observatories - Remote sensing - Space optics - TexturesUncontrolled terms:Classification - Color feature - HSI - SAN - Shape adaptive neighborhood - Shape feature - Texture featureClassification code:933 Solid State Physics - 723.5 Computer Applications - 731.1 Control Systems - 741 Light, Optics and Optical Devices - 741.1 Light/Optics - 742 Cameras and Photography - 751.1 Acoustic Waves - 723.2 Data Processing and Image Processing - 716 Telecommunication; Radar, Radio and Television - 657 Space Physics - 656.1 Space Flight - 443 Meteorology - 402.1 Industrial and Agricultural Buildings - 716.4 Television Systems and EquipmentDOI:10.1117/12.815857Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

We first provide a decision analysis justification for the VaR approach based disappointment decision making arguments. Then we provide applications to inventory management based on VaR risk exposure. Both single period and multiperiod inventory models are considered. Although the mathematical problems arising from an application of the VaR approach, tuned to current practice in financial risk management, are difficult to solve analytically, solutions can be found by application of standard computational and simulation techniques.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:To elucidate the role of native defects in determining the electrical properties of In<inf>1-x</inf>Ga<inf>x</inf>N and InN, High-energy particle irradiation has been used to intentionally introduce point defects into In <inf>x</inf>Ga<inf>1-x</inf>N alloys and to study the dependence of the electron mobility on electron concentrations varying from mid-10¹⁸ to mid-10²⁰ cm^-3 for InN. We find that high-energy particle irradiation produces donor-like defects in In<inf>x</inf>Ga <inf>1-x</inf>(x&gt;0.34), while acceptor-like defects form in Ga-rich In <inf>x</inf>Ga<inf>1-x</inf>N (x&lt;0.34). We also show that the electron mobility is limited by scattering from the ionized defects created in InN by high-energy particle irradiation, resulting in a strong correlation between mobility and electron concentration. A sufficiently high irradiation dose pins the Fermi level at the Fermi stabilization energy (E<inf>FS</inf>), as predicted by the Amphoteric Defect Model. Furthermore, we suggest that the high-energy particle irradiation-induced defects may be triply charged donors.Number of references:17Main heading:Electron irradiationControlled terms:Defects - Electric properties - Electron mobility - Electrons - Fermions - Gallium

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:In this paper, by using the transfer matrix theory and the dispersion relation principle, via math tool processing numerical value simulation get the energy band, the limited field and the dispersion characteristic of one-dimensional photonic crystals with negative-index materials, we find there are two photonic band gap, the lower forbidden band which is called zero- n&macr; gap remains nearly invariant under a various incident angle, while the higher one which is called Bragg gap changes ceaselessly with the increasing incident angle. Through introducing the defect we found that the defect mode inside the zero- n&macr; gap remains invariant with the scaling of non-defect part. Conversely, the defect mode inside the Bragg gap shifts greatly in frequency with scaling. The studying of the dispersion relation shows that the width of the zero- n&macr; gap enlarges, but the middle of each gap hardly changes, on the contrary the middle of a Bragg gap will shift noticeably while the width of the gap will change a little when the ratio of the thicknesses of the two types of layers varies and that the zero- n&macr; gap that distinguishes itself from a Bragg gap in that it is invariant with scaling. The emphasis of this paper lies in analyzing the characteristic of this type of photonic crystals.Number of references:10Main heading:Photonic band gapControlled terms:Crystal atomic structure - Crystals - Defects - Gallium alloys - Materials properties - Mathematical models - Matrix algebra - Nanostructures - Photonic crystals - Photonics - Quantum theory - Transfer matrix methodUncontrolled terms:Bragg gaps - Defect modes - Dispersion characteristics - Dispersion relations - Energy bands - Forbidden bands - Incident angles - Negative refractions - Negative-index materials - Numerical value simulations - Photonic bands - Tool processing - Transfer matrix - Two typesClassification code:761 Nanotechnology - 801.4 Physical Chemistry - 802.3 Chemical Operations - 921 Mathematics - 921.1 Algebra - 951 Materials Science - 931.2 Physical Properties of Gases, Liquids and Solids - 931.4 Quantum Theory; Quantum Mechanics - 933 Solid State Physics - 933.1 Crystalline Solids - 933.1.1 Crystal Lattice - 931.3 Atomic and Molecular Physics - 744 Lasers - 741.3 Optical Devices and Systems - 421 Strength of Building Materials; Mechanical Properties - 423 Non Mechanical Properties and Tests of Building Materials - 482.2 Minerals - 531.2 Metallography - 549.3 Others, including Bismuth, Boron, Cadmium, Cobalt, Mercury, Niobium, Selenium, Silicon, Tellurium and Zirconium - 712 Electronic and Thermionic Materials - 712.1 Semiconducting Materials - 714.2 Semiconductor Devices and Integrated Circuits - 717 Optical Communication - 741.1 Light/OpticsDOI:10.1117/12.757203Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

mechanisms: apoptosis and necrosis. Immunological responses induced by PDT has been mainly associated with necrosis while apoptosis associated immune responses have not fully investigated. Heat shock proteins (HSPs) play an important role in regulating immune responses. In present study, we studied whether apoptotic tumor cells could induce immune response and how the HSP70 regulates immune response. The endocytosis of tumor cells by the activated macrophages was observed at single cell level by LSM. The TNF-&alpha; release of macrophages induced by co-incubated with PDT-apoptotic tumor cells was detected by ELISA. We found that apoptotic tumor cells treated by PDT could activate the macrophages, and the immune effect decreased evidently when HSP70 was blocked. These findings not only show that apoptosis can induce immunological responses, but also show HSP70 may serves as a danger signal for immune cells and induce immune responses to regulate the efficacy of PDT.Number of references:25Main heading:Photodynamic therapyControlled terms:Cell death - Macrophages - Proteins - TumorsUncontrolled terms:Macrophage immune response - Tumor cellsClassification code:461.2 Biological Materials and Tissue Engineering - 461.6 Medicine and Pharmacology - 461.9 Biology - 461.9.1 Immunology - 804.1 Organic CompoundsTreatment:Theoretical (THR)DOI:10.1117/12.759703Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Three-dimensional point spread function (3D-PSF) of RIKES nonlinear confocal microscopy in isotropic media is derived with Fourier imaging theory and RIKES theory. The impact of nonlinear property of RIKES on the spatial resolution and imaging properties of confocal microscopy have been analyzed in detail. It is proved that RIKES nonlinear confocal microscopy can simultaneously provide more information than two-photon confocal microscopy concerning molecular vibration mode, vibration orientation and optically induced molecular reorientation, etc. It is shown that RIKES nonlinear confocal microscopy significantly enhances the spatial resolution and imaging quality of confocal microscopy and achieves much higher resolution than that of two-photon confocal microscopy.

Publisher:Maney Publishing, Suite 1C, Joseph's Well, Hanover Walk, Leeds, LS3 1AB, United KingdomAbstract:The pitting susceptibility of passive films on iron in chloride containing solution, formed using three different inorganic inhibitors, chromate, nitrite and bicarbonate, is determined using linear sweep voltammogram. It is found that the pitting susceptibility becomes stronger in the order of the passive films formed in 0&middot01M chromate, 0&middot1M nitrite and 0&middot5M bicarbonate. The difference in pitting susceptibility is explained by the difference in electronic property of the passive films, which is determined using Mott-Schottky measurements. The donor density of the passive films formed in bicarbonate is highest, followed by nitrite and then by chromate, although the concentration of bicarbonate is five times that of nitrite and 50 times that of chromate. This suggests that the passive film formed in bicarbonate Is most susceptible to attack by chloride ions. &copy; 2008 Institute of Materials, Minerals and Mining.Number of references:37Main heading:PittingControlled terms:Chromates - Concentration (process) - Electronic propertiesUncontrolled terms:Chloride ions - Donor density - Inorganic inhibitor - Inorganic inhibitors - Iron - Linear sweep voltammogram - Mott-Schottky - Passive film - Passive films - Pitting susceptibilityClassification code:539.1 Metals Corrosion - 701.1 Electricity: Basic Concepts and Phenomena - 802.3 Chemical Operations - 804.2 Inorganic CompoundsDOI:10.1179/174327807X214842Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Box 10, Bellingham WA, WA 98227-0010, United StatesAbstract:ChanSu(CS), a traditional Chinese medicine, is composed of many chemical compoments. It is isolated from the dried white secretion of the auricular and skin glands of toads, and it has been widely used for treating the heart diseases and other systemic illnesses. However, it is difficult to judge antitumor effect of agents derived from ChanSu and the underlying mechanism of ChanSu inducing cell apoptosis is still unclear. This report was performed to explore the inhibitory effect and mechanism of ChanSu on human lung adenocarcinoma cells (ASTC-a-1). Fluorescence emission spectra and fluorescence resonance energy transfer (FRET) were used to study the caspase-3 activation during the ChanSu-induced human lung adenocarcinoma (ASTC-a-1) cell apoptosis. CCK-8 was used to assay the inhibition of ChanSu on the cell viability. The cells expressing stably with SCAT3 was used to examine if caspase-3 was activated by ChanSu using acceptor photobleaching technique. Our data showed that treatment of ASTC-a-1 cell with ChanSu resulted in the inhibition of viability and induction of apoptosis in a dose-dependent manner and the SCAT3 was almost cleaved 24 h after ChanSu treatment, implying that ChanSu induced cell apoptosis via a caspase-3-dependent death pathway. Our findings extend the knowledge about the cellular signaling mechanisms mediating ChanSu-induced apoptosis.Number of references:17Main heading:Cell deathControlled terms:Biological organs - Disease control - Fluorescence microscopy - TumorsUncontrolled terms:Cellular signaling - Skin glandsClassification code:461.2 Biological Materials and Tissue Engineering - 461.7 Health Care - 461.9 Biology - 931.4 Quantum Theory; Quantum Mechanics - 941.3 Optical InstrumentsTreatment:Theoretical (THR)DOI:10.1117/12.761422Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

The imaging theory of RIKES confocal microscopy with Gaussian beam is derived. The imaging properties of RIKES confocal microscopy and the impact of different beam waist widths of Gaussian beam on the lateral and axial resolution have been analyzed in detail. It is proved that RIKES confocal microscopy has high sensitivity and high resolution, besides capability to characterize inherent structural features, such as vibration mode, vibration orientation, and optically induced molecular reorientation etc. Therefore, nonlinear Raman confocal microscopy that is based on RIKES has potential to provide a novel characteristic imaging method comparable to the existing imaging techniques based on other nonlinear optical processes, such as two-photon fluorescence, second harmonic generation (SHG) and coherent anti-Stoke Raman scattering (CARS).Number of references:27Main heading:Nonlinear opticsControlled terms:Confocal microscopy - Gaussian beams - Harmonic generation - Imaging techniques - Optical transfer function - Photons - Raman scatteringUncontrolled terms:Nonlinear confocal microscopy - Raman susceptibility - Vibration orientationClassification code:931.3 Atomic and Molecular Physics - 746 Imaging Techniques - 744.9 Laser Applications - 741.3 Optical Devices and Systems - 741.1.1 Nonlinear Optics - 713.2 Oscillators - 711 Electromagnetic WavesTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1080/09500340701445237Database:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.

Treatments with 3, 6, 9 or 12 g of tourmaline ceramic balls in a 50 ml culture showed significant stimulation of the growth of the three microorganisms. In optimal treatments with 12 g of tourmaline balls, the growth of S. cerevisiae, L. acidophilus, and A. oryzae was increased by 34, 32 and 10%, respectively. After 72 h fermentation of S. cerevisiae, total carbohydrate content in the culture medium was decreased by 65% and ethanol production was increased by 150%. Total carbohydrate content was decreased by 80% and the pH value was decreased by 0.3, as a result of organic acid production in the medium of L. acidophilus after 72 h fermentation. In the case of A. oryzae, enzyme activities of protease and amylase were increased by 90 and 31%, respectively, after 96 h fermentation. Results indicated that tourmaline stimulates initiation of growth in the early lag stage and increases production of metabolites at a later stage of fermentation. The strong stimulatory effect of tourmaline on growth, utilization of substrates and production of metabolites in the three microorganisms suggests a potential application in the fermentation industry. &copy; 2007 Springer Science+Business Media B.V.Number of references:33Main heading:MicroorganismsControlled terms:Carbohydrates - Enzyme activity - Fermentation - Metabolism - Silicates - YeastUncontrolled terms:Aspergillus oryzae - Lactobacillus acidophilus - Protease - TourmalineClassification code:461.8 Biotechnology - 461.9 Biology - 804.1 Organic Compounds - 812 Ceramics, Refractories and Glass - 822.3 Food ProductsTreatment:Theoretical (THR); Experimental (EXP)DOI:10.1007/s11274-007-9529-xDatabase:CompendexCompilation and indexing terms, Copyright 2008 Elsevier Inc.
