Interstitial-Dependent Enhanced Photoluminescence: A Near-Field Microscopy on Single Spheroid to Dimer, Tetramer, and Few Particles Gold Nanoassembly (2017)

Interstitials to be active or inactive depend on the characteristics of nanoaggregate. In this perspective, near-field scanning optical microscopy has been utilized to probe well-defined monomer, dimer, tetramer, and small assembly of gold nanoparticles of 60 nm diameter with spatial resolution of ∼35 nm. Confinement of localized surface plasmon resonances (LSPRs)-mediated near electromagnetic (EM) field distribution was observed through two-photon induced photoluminescence (TPI-PL) since TPI-PL emission is proportional to the fourth power of induced EM-field. It was revealed that the intensity of TPI-PL observed in closely connected nanoparticles was very strong with reference to those obtained in the presence of isolated nanoparticles of the same size. Among the closely connected nanoparticles, interparticle gap and interparticle axes played a vital role in TPI-PL emission enhancement, as was evident and observed directly through TPI-PL intensity distribution. Correlated local geometry and emission distribution confirmed that interstitials along the active interparticle axes exhibits confined and enhanced TPI-PL emission. The emission intensity for dimers was found higher than that of tetramer of gold nanoparticles. In case of small assembly of the same gold nanoparticles, intensity was observed to be the highest of all along with wider full width at half-maximum of 188.09 nm, more than double of those obtained at dimers and tetramer. The observations were further demonstrated as a function of EM near-field distribution, as it is well-known that TPI-PL emission is enhanced by LSPRs-assisted EM-field localization. Model systems were designed along with geometries and parameters very similar to those under investigation. Finite-difference time-domain analysis was carried out to deduce near EM-field distributions at various deterministic factors such as size, interparticle gap, incident polarization, etc. A plausible explanation of enhanced and confined TPI-PL emissions in archetype interstitials of well-known plasmonic systems was highlighted.
Maximum entropy analysis of dispersed seismic signals (1986)

Abstract Conventional moving-window analyzers based on Fourier transforms sometimes lack the resolution required to separate each of the modes in a seismic wave-guide. It is possible to enhance the resolution of a moving-window analyzer by using a maximum entropy power spectral estimator to approximate the spectrum of each windowed segment of a trace. Barrodale and Erickson have developed a suitable maximum entropy algorithm which can also be applied to estimating the parameters required in the fast recompression of in-seam seismic arrivals.The Barrodale-Erickson maximum entropy algorithm appears to need a sample rate of approximately ten times the Nyquist rate in order to generate meaningful maximum entropy spectra. The required increase can be achieved in the laboratory by applying an accurate interpolator to field records. Noise captures the maximum entropy spectrum if the input signal-to-noise ratio falls much below 10 dB. Use of a maximum entropy spectral analyzer aids in both identifying modes in a waveguide system and estimating the group velocity-frequency characteristic parameter.
The effect of ambient temperature on capillary vascular malformations (2006)

Superficial capillary vasodilation within CM is achievable by raising ambient temperature, including in those patients resistant to PDL treatment, potentially allowing further clearance of these lesions.
Effect of Flow Rate Changes and Pulsing on the Treatment of Source Zones by in Situ Air Sparging (1999)

Laboratory-scale two-dimensional aquifer physical model studies were conducted to qualitatively assess how changes in air injection rate, air injection pulsing, and chemical type affect the rate and extent of removal by in situ air sparging. In this work, the treatment of immiscible-phase source zones in coarse media has been simulated. To provide a basis for comparison, equivalent unsaturated-soil soil vapor extraction-like simulation experiments were also conducted. Results suggest that, (i) initially, removal occurs from within saturated zone air flow channels at rates similar to those observed for soil vapor extraction, (ii) during this initial period, removal rates are proportional to air flow rate and equilibrium chemical vapor concentrations, (iii) while increased air injection rates improve volatilization rates in the short-term, the long-term cumulative removal efficiency may not be affected unless the saturated zone air flow distribution changes significantly with flow rate, (iv) pulsing the air injection can improve the long-term cumulative removal efficiency, and (v) while short-term removal efficiency improves with increasing flow rate and vapor pressure, the long-term removal efficiency appears to improve with increasing solubility.

Regulation of thrombomodulin by tumor necrosis factor-alpha: comparison of transcriptional and posttranscriptional mechanisms (1991)

The procoagulant properties of cultured vascular endothelial cells are enhanced in response to inflammatory cytokines such as tumor necrosis factor-alpha (TNF). A major component of this response is a reduction in expression of thrombomodulin, a cell surface cofactor for the activation of protein C. Regulation of thrombomodulin expression by TNF has been reported to occur through multiple mechanisms. To determine the relative roles of transcriptional and posttranscriptional regulation, the effect of TNF on the turnover of thrombomodulin protein and mRNA was examined in human and bovine endothelial cells. Quantitative nuclease S1 protection assays showed a 70% to 90% reduction in thrombomodulin mRNA within 4 hours of the addition of 1.0 nmol/L TNF to the culture medium. The decrease in thrombomodulin mRNA resulted from inhibition of transcription, followed by rapid degradation of thrombomodulin transcripts (t1/2 less than or equal to 3 hours). In pulse-chase incubations, thrombomodulin synthesis decreased parallel with mRNA, but the rate of degradation of radiolabeled thrombomodulin was not significantly altered by TNF. Human thrombomodulin was degraded with a t1/2 of 8.2 +/- 2.4 hours (SD) or 7.5 +/- 1.3 hours (SD) in the absence or presence of TNF, respectively. We conclude that TNF acts primarily to inhibit thrombomodulin transcription. The subsequent decrease in activity results from the inherent instability of thrombomodulin mRNA and protein in these cells, and not from the regulation of thrombomodulin degradation.
<title>Portable digital lidar: a compact stand-off bioagent aerosol sensor</title> (2001)

Remote detection of biological warfare agents (BWA) is crucial for providing early warning to ensure maximum survivability of personnel in the battlefield and other sensitive areas. Although the current generation of stand- off aerosol and fluorescence lidars have demonstrated stand- off detection and identification of BWA, their large size and cost make them difficult for field use. We have introduced a new eye-safe portable digital lidar (PDL) technique based on digital detection that achieves orders of magnitude reduction in the size, cost and complexity over the conventional lidar, while providing an equal or better sensitivity and range. Excellent performance has been obtained with two of our PDL sensors during two bio-aerosol measurement campaigns carried out at Dugway Proving Grounds. In the JFT 4.5 (Oct 98) tests, high aerosol sensitivity of 300 ppl of biosimulant particles at up to 3 km was demonstrated with an eye-safe wavelength (523nm) aerosol micro PDL that utilized a 8 inch telescope, <10(mu) J/pulse energy at 2.5kHz, photon counting digital detection and 2 sec averaging. For the JBREWS DFT (June 99) tests an eye-safe two wavelengths (523nm and 1.047mum) horizontally scanned, aerosol micro PDL with the same 8 inch telescope was utilized. With this lidar, high sensitivity, preliminary differentiation between natural and unusual clouds, and the ability to track the aerosol cloud location, their wind speed and direction were also demonstrated. Lidar simulations of both PDL and conventional analog detection have been performed. Based on these model calculations and experimental results an analysis and comparison of the inherent capabilities of two types of systems is given.
User interface design for SONET networks (1992)

The evolution of user interface design from first-stage element management systems to potential third-stage service management systems is reviewed. Requirements for user interface design are discussed. It is argued that network and service management systems for synchronous optical networks (SONETs) will benefit from the object-oriented programming approaches now being popularized in graphical windowed interfaces.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Detection of cancer cells in prostate tissue with time-resolved fluorescence spectroscopy (2011)

Goals: Improving cancer diagnosis is one of the important challenges at this time. The precise differentiation between benign and malignant tissue is in the oncology and oncologic surgery of the utmost significance. A new diagnostic system, that facilitates the decision which tissue has to be removed, would be appreciated. In previous studies many attempts were made to use tissue fluorescence for cancer recognition. However, no clear correlation was found between tissue type and fluorescence parameters like time and wavelength dependent fluorescence intensity I(t, λ). The present study is focused on cooperative behaviour of cells in benign or malignant prostates tissue reflecting differences in their metabolism. Material and Methods: 50 prostate specimens were obtained directly after radical prostatectomy and from each specimen 6 punch biopsies were taken. Time-resolved fluorescence spectra were recorded for 4 different measurement points for each biopsy. The pathologist evaluated each measurement point separately. An algorithm was developed to determine a relevant parameter of the time dependent fluorescence data (fractal dimension <i>D<sub>F</sub></i> ). The results of the finding and the <i>D<sub>F</sub></i> -value were correlated for each point and then analysed with statistical methods. Results: A total of 1200 measurements points were analysed. The optimal algorithm and conditions for discrimination between malignant and non-malignant tissue areas were found. The correct classification could be stated in 93.4% of analysed points. The ROC-curve (AUC = 0.94) confirms the chosen statistical method as well as it informs about the specificity (0.94) and sensitivity (0.90). Conclusion: The new method seems to offer a very helpful diagnostic tool for pathologists as well as for surgery.
Plantar Fasciitis: Etiology and Treatment (1999)

Plantar fasciitis is a common pathological condition of the foot and can often be a challenge for clinicians to successfully treat. The purpose of this article is to present and discuss selected literature on the etiology and clinical outcome of treating plantar fasciitis. Surgical and nonsurgical techniques have been used in the treatment of plantar fasciitis. Nonsurgical management for the treatment of the symptoms and discomfort associated with plantar fasciitis can be classified into 3 broad categories: reducing pain and inflammation, reducing tissue stress to a tolerable level, and restoring muscle strength and flexibility of involved tissues. Each of these treatments has demonstrated some level of effectiveness in alleviating the symptoms of plantar fasciitis. Previous studies have grouped all forms of nonsurgical therapy together. It is, therefore, difficult to determine if one type of treatment is more effective compared with another. Until such research is available, the clinician would be wise to include treatments from all 3 categories.
OBSERVATION OF STELLATE GANGLION BLOCK IN THE TREATMENT OF BREAST CANCER CHEMOTHERAPY-INDUCED PHLEBITIS PAIN (2013)

Objective:To observe the effect of stellate ganglion block(SGB) in the treatment of breast cancer chemotherapy-induced phlebitis pain. Methods: 114 patients with breast cancer chemotherapy-induced phlebitis were divided into two groups, with 57 in the observation group and the other 57 in the controlgroup). The observationgroup were treated with both SGB and local hydropathic compress with 50% magnesium sulfate, and the controlgroup received local hydropathic compress with 50% magnesium sulfate only. The result comparison was performed using visual analogue scale,(VAS). Results: A significant difference between two groups(P 0.05) was observed, and the observation group was superior to the control group in improving pain-reducing effects. Conclusion:SGB has a significant therapeutic effect on breast cancer chemotherapy-induced phlebitis pain.

A forkhead transcription factor FKHR up‐regulates lipoprotein lipase expression in skeletal muscle (2003)

Lipoprotein lipase (LPL) plays a role in lipid usage in skeletal muscle by hydrolyzing plasma triglycerides into fatty acids, which are further utilized for beta-oxidation. Lipid usage is stimulated during fasting, diabetes mellitus and exercise, concomitant with enhanced LPL expression in skeletal muscle. Here we show that the forkhead type transcription factor FKHR is strongly induced in skeletal muscle in fasting mice, in mice with streptozotocin-induced diabetes and in mice after treadmill running. Ectopic expression of FKHR enhanced LPL gene expression in C2C12 muscle cells in culture. These results implicate FKHR as an important modulator of lipid metabolism in skeletal muscle.
Brugia malayi and Acanthocheilonema viteae: antifilarial activity of transglutaminase inhibitors in vitro (1991)

The possible involvement of transglutaminase-catalyzed reactions in survival of adult worms, microfilariae (mf), and infective larvae of the filarial parasite Brugia malayi was studied in vitro by using the specific pseudosubstrate monodansylcadaverine (MDC) and the active-site inhibitors cystamine or iodoacetamide. These inhibitors significantly inhibited parasite mobility in a dose-dependent manner. This inhibition was associated with irreversible biochemical lesions followed by filarial death. A structurally related, inactive analog of MDC, dimethyldansylcadaverine, did not affect the mobility or survival of the parasites. Adult worms failed to release mf when they were incubated in the presence of MDC or cystamine, and this inhibitory effect on mf release was concentration dependent. Similar embryostatic and macrofilaricidal effects of MDC were observed in Acanthocheilonema viteae adult worms. These studies suggest that transglutaminase-catalyzed reactions may play an important role in the growth, development, and survival of filarial parasites.

Transmission disequilibrium test and haplotype analysis of the MCP-1 -2518G/A polymorphism with Tourette syndrome in Chinese Han trios (2012)

The purpose of this study was to investigate the association between MCP-1 -2518G/A polymorphism and Tourette syndrome (TS) in Chinese Hanpopulation. Wecollected 324 Chinese Han individuals from 108 TS nuclear families from Chinese Hanpopulation andemployed polymerase chain reactionand restrictionenzyme digestion for determining thegenotype of MCP-1 -2518G/A polymorphism. The data were analyzed using the transmission disequilibrium test, the genotype haplotype relative risk and haplotype-based haplotype relative risk. No biases were observed in the transmission of either of the two alleles (χ2 = 0.016, df = 1, P = 0.898) to the affected probands in the total sample. The analyses of transmission disequilibrium test, haplotype relative risk and haplotype-based haplotype relative risk did not indicate any associations at MCP-1 -2518G/A with TS. Our results suggest that MCP-1 -2518G/A is not associated with susceptibility of Tourette syndrome in Chinese Han population.
Polarization properties of a nematic liquid-crystal spatial light modulator for phase modulation (2005)

The polarization properties of a nematic zero-twist liquid-crystal (NLC) spatial light modulator (SLM) were studied. A large ratio between the liquid-crystal (LC) layer thickness and the pixel pitch combined with spatial variations in the applied electric field causes fringing fields between pixels. Depending on the LC alignment, the electric field components within the LC layer can result in a twist deformation. The produced inhomogeneous optical anisotropy affects the polarization of light propagating through the device. We experimentally examined polarization effects in different diffraction orders for both binary and blazed phase gratings. Simulations of the LC deformation together with finite-difference time-domain simulations for the optical propagation were used to calculate the corresponding far-field intensities. It was demonstrated how rigorous simulations of the NLC SLM properties can be used to understand the polarization features of different diffraction orders.
An adaptive data sorter based on probabilistic neural networks (1991)

Based on a self-organized, probabilistic neural network (PNN) paradigm, a parallel network can be used to sort data parameters into classes with high sorting accuracy and low fragmentation. The capabilities of the sorter, as applied to ESM (electronic support measure) pulse-data sorting, are shown. The PNN implements the statistical Bayesian strategy by computing a joint probability density over all input data parameters to match a group of candidate data classes. The sorting is accomplished by assigning then inputs to the most likely group with highest probability density estimate. Based on test data from an ESM system, the PNN has shown significant improvement over conventional rule-based techniques. The parallel computer architecture of PNN is well-suited for VLSI chip implementation. An 80000 gate semicustom chip design concept is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Path planning and intelligent scheduling of multi-AGV systems in workshop (2017)

With the continuous development of intelligent logistics, the application of Automated Guided Vehicles (AGVs) increasingly becomes popular in many industrial fields. However, there are a series of problems in multi-AGV systems, such as resource allocation, conflict and deadlock. It is difficult to plan the shortest path for each AGV without conflict and collision in multi-AGV systems. In this paper, a multi-AGV scheduling system in workshop is established by using the unidirectional directed graph method and the A* algorithm for path planning of AGVs. In addition, the system is realized by programming and a simulation experiment of 20 AGVs is set up. Finally, the simulation results show that the system can effectively solve the conflict problem of AGVs, and is stable and high real-time. The system is easily extended to their similar multi-AGV scheduling systems, and has a great application value.
Circulating levels of pro‐atrial natriuretic peptide in lower respiratory tract infections (2006)

Current progress in proteomic study of hepatitis C virus-related human hepatocellular carcinoma (2005)

Chronic infection with hepatitis C virus (HCV) is known to be a risk factor for not only cirrhosis and steatosis but also hepatocellular carcinoma (HCC). A number of diagnostic and prognostic molecular markers are being identified by transcriptomic and proteomic analysis of HCC today. However, the analyses are performed on HCC in general, and the studied tissues are HCV infected, HBV infected, infected with both or neither, or the infection status may be unknown. The authors performed proteomic analysis of cancerous and noncancerous tissues from HCC patients with HCV infection, and determined that, in the cancerous tissues, HSP70 family proteins such as GRP78, HSC70, GRP75 and HSP70.1, glutaine synthetase isoforms, HSP60, alpha-enolase, phosphoglycerate mutase 1, ATP synthetase beta chain and triosephosphate isomerase were increased whereas albumin, ferritin light chain, smoothelin, tropomyosin beta chain, arginase 1, aldolase B and kietohexokinase were decreased. The aim of this study is to understand the pathogenesis of HCV-HCC using proteomic analysis of samples from HCV-HCC patients on which transcriptomics has already been performed.
