Visible light communication via dimmable LED lamps using pulses of equal shape (2011)

This paper, for the first time, presents the feasibility of employing the transmission of equally shaped pulses to accommodate both dimming and Visible Light Communication (VLC). Adjustment of the brightness experienced by the human eye is accomplished by varying the number of pulses within a set dimming frame. Duration of the pulses and dimming frames are such that the eye detects an average illumination level without experiencing flicker. Several constant pulse shape schemes are introduced with their merits and drawbacks examined. A major advantage of the proposed schemes is the fact that they allow for simple threshold detection.
Subunit composition of the heteromeric cytosolic aryl hydrocarbon receptor complex. (1994)

In a previous cross-linking study we have shown that the cytosolic aryl hydrocarbon receptor (AhR) complex has a heterotetrameric structure (Perdew, G. H. (1992) Biochem. Biophys. Res. Commun. 182, 55-62). In this report, both cross-linked and [35S]methionine-labeled Hepa 1c1c7 cytosol were used to characterize the subunit composition of the AhR complex by immunoprecipitation with an AhR polyclonal antibody followed by immunochemical analysis using antibodies against the AhR and 90-kDa heat shock protein (hsp90). Results indicated that the four subunits found in cross-linking experiments were composed of three species: the AhR ligand binding subunit, hsp90, and an unknown 43-kDa protein. The stoichiometry of hsp90 present in each AhR complex was determined in two separate experiments: 1) from cross-linking experiments, stoichiometry was determined by quantitative immunoblotting with anti-AhR and anti-hsp90 antibodies followed by quantitation with 125I-counterantibody on protein blots; 2) using 35S-labeled Hepa 1 cytosol, the hsp90/AhR stoichiometry was determined by immunopurifying receptor complexes, and the amount of 35S-labeled AhR and hsp90 was assessed. The stoichiometry values obtained were 2.4 and 1.72 mol of hsp90/mol of AhR using each experimental approach, respectively.
Fast subscriber identification based on the zero knowledge principle for multimedia content distribution (2010)

In this article, an innovative method is proposed for the realisation of zero knowledge subscriber identification schemes that is suitable for multimedia content distribution applications. The fundamental principle underlying the proposed method is the concept of using one-way Boolean functions as transformations for the zero knowledge identification. This enables the increase of the speed of completion of the identification process by two to three orders of magnitude, compared to the corresponding speed when using modular arithmetic with large numbers. A method for the establishment of one way Boolean functions for zero knowledge identification has been developed. Two examples for the application of the proposed method are presented.
Evaluation of an Absorption Heat Pump to Mitigate Plant Capacity Reduction Due to Ambient Temperature Rise for an Air-Cooled Ammonia and Water Cycle: Preprint (2001)

Air-cooled geothermal plants suffer substantial decreases in generating capacity at increased ambient temperatures. As the ambient temperature rises by 50 F above a design value of 50 F, at low brine-resource temperatures, the decrease in generating capacity can be more than 50%. This decrease is caused primarily by increased condenser pressure. Using mixed-working fluids has recently drawn considerable attention for use in power cycles. Such cycles are more readily amenable to use of absorption ''heat pumps.'' For a system that uses ammonia and water as the mixed-working fluid, this paper evaluates using an absorption heat pump to reduce condenser backpressure. At high ambient temperatures, part of the turbine exhaust vapor is absorbed into a circulating mixed stream in an absorber in series with the main condenser. This steam is pumped up to a higher pressure and heated to strip the excess vapor, which is recondensed using an additional air-cooled condenser. The operating conditions are chosen to reconstitute this condensate back to the same concentration as drawn from the original system. We analyzed two power plants of nominal 1-megawatt capacity. The design resource temperatures were 250 F and 300 F. Ambient temperature was allowed to rise from a design value of 50 F to 100 F. The analyses indicate that using an absorption heat pump is feasible. For the 300 F resource, an increased brine flow of 30% resulted in a net power increase of 21%. For the 250 F resource, the increase was smaller. However, these results are highly plant- and equipment-specific because evaluations must be carried out at off-design conditions for the condenser. Such studies should be carried out for specific power plants that suffer most from increased ambient temperatures.
Protective Role of Genistein in Acute Liver Damage Induced by Carbon Tetrachloride (2007)

Genistein has anti-inflammatory and antinecrotic effects on experimental liver damage caused by CCl4. Genistein reduces liver damage by preventing lipid peroxidation and strengthening antioxidant systems.
LIF Velocity Measurement of Sputtered Boron Atoms from Boron Nitride Target (2010)

Details of the boron nitride (BN) sputtering process are of interest for diagnostics and modeling of Hall thruster erosion. This contribution presents velocity distributions of sputtered boron atoms from BN targets. Measurements were performed for normally incident argon ions at energies of 300, 800, and 1200 eV, and xenon ion at 1200 eV. The velocity distributions were found using laser induced fluorescence (LIF) spectroscopy of boron with a tunable diode laser system in the vicinity of 250 nm. The LIF velocity profiles for sputtered boron from BN were fitted with Thompson distributions giving surface binding energy of Eb=4.8±0.2 eV. Measurements were validated with a pure boron target giving a binding energy of Eb=5.7±0.3 eV in agreement with published values.
Heat capacity of tin monoselenide (2006)

The heat capacity data reported for solid tin selenide, SnSe, are critically evaluated and optimized in a broad temperature range. The thermodynamic functions of SnSe are calculated in the range 298.15–700 K.
Natural Polysaccharides for siRNA Delivery: Nanocarriers Based on Chitosan, Hyaluronic Acid, and Their Derivatives (2019)

Natural polysaccharides are frequently used in the design of drug delivery systems due to their biocompatibility, biodegradability, and low toxicity. Moreover, they are diverse in structure, size, and charge, and their chemical functional groups can be easily modified to match the needs of the final application and mode of administration. This review focuses on polysaccharidic nanocarriers based on chitosan and hyaluronic acid for small interfering RNA (siRNA) delivery, which are highly positively and negatively charged, respectively. The key properties, strengths, and drawbacks of each polysaccharide are discussed. In addition, their use as efficient nanodelivery systems for gene silencing applications is put into context using the most recent examples from the literature. The latest advances in this field illustrate effectively how chitosan and hyaluronic acid can be modified or associated with other molecules in order to overcome their limitations to produce optimized siRNA delivery systems with promising <i>in vitro</i> and <i>in vivo</i> results.
Influence of particle interaction on coercivity and squareness of thin film recording media (1981)

Digital Recording density in continuous thin films can be significantly larger than in conventional particulate media. For this reason, there is much active research and development in such thin film recording media at present. However, no detailed calculation leading to a satisfactory explanation for the high squareness and an Hc decreasing monotonically with film thickness t has appeared. Using a model of strongly interacting anisotropic grains and neglecting exchange at grain boundaries, we examined here particle interaction and its influence on S and Hc. It is shown that the rather high squareness found in such media (e.g., S?0.8 for films of Co with t≳200Å) is related to strong dipolar interaction between the constituent grains. Although such films are continuous, surface roughness due to microscopic film thickness variation from grain to grain-boundary can be appreciable. Indeed, our calculation shows that these thickness variations can account for Hc and its variation with t experimentally observed.

The Management of Premature Ejaculation (2011)

In general, men are able to control the timing of their ejaculation reasonably well, even if ejaculation may sometimes occur earlier than they would have wished. The probability that it may take a longer time at a next occasion makes most men not to worry about their ejaculation. However, this is not the case in men who suffer from premature ejaculation (PE). Males affected by PE are often continuously worried about and even obsessed by their ejaculation. As soon as ejaculation has occurred too early again, these males feel frustrated, are full of shame, or may feel guilty towards their sexual partner.
Shape Control of Large Membrane Reflector with PVDF Actuation (2007)

A high precision membrane reflector shape control system is presented by this paper. In this system, PVDF polymer actuators are attached to the back of the reflector to produce contraction/expansion forces to adjust the shape of the membrane reflector. An analytical model of the system which includes the membrane reflector, actuator and controller was developed to investigate the functionality of this control system on a 35-m diameter membrane reflector. The performance of this system under external disturbances such as in space thermal loads and W-error due to inflation has been investigated by this study. The feasibility of this control system has been demonstrated by numerical cases.
MMSE reception and successive interference cancellation for MIMO systems with high spectral efficiency (2005)

In this paper, we investigate the performance in terms of symbol error probability (SEP) of multiple-input-multiple-output (MIMO) systems with high spectral efficiency. In particular, we consider the coherent detection of M-PSK signals in a flat Rayleigh-fading environment. We focus on spectrally efficient MIMO systems where, after serial-to-parallel conversion, several substreams of symbols are simultaneously transmitted by using an antenna array, thereby increasing the spectral efficiency. The reception is based on linear minimum mean-square-error (MMSE) combining, eventually followed by successive interference cancellation. Exact and approximate expressions are derived for an arbitrary number of transmitting and receiving antenna elements. Simulation results confirm the validity of our analytical methodology.
Uncongruent laser ablation and electroless metallization of SiC (1996)

Experimental results on the ablation of a SiC single crystal in air under irradiation with a XeCl excimer laser beam are presented. XPS analysis reveals the Si enrichment of the ablated areas under an energy density of the laser beam of 1 to 3.5 J/cm2 and the formation of SiOx in the ablated areas. The nonstoichiometric ablation of SiC allows one to activate selectively the SiC surface for metal deposition from an electroless plating solution. Both Ni and Cu deposits show a good adherence to the SiC surface (up to 0.5 N/mm2). Similar results are observed with SiC ceramics with a better adherence of the electroless metal deposit. The adherence of the deposit to the ablated SiC samples increases upon HF treatment.
AAV-mediated gene transfer for retinal diseases (2006)

Vectors based on the adeno-associated virus (rAAV) are able to transduce the retina of animal models, including non-human primates, for a long-term period, safely and at sustained levels. The ability of the various rAAV serotypes to transduce retinal target cells has been exploited to successfully transfer genes to photoreceptors, retinal pigment epithelium and the inner retina, which are affected in many inherited and non-inherited blinding diseases. rAAV-mediated, constitutive and regulated gene expression at therapeutic levels has been achieved in the retina of animal models, thus providing proof-of-principle of gene therapy efficacy and safety in models of dominant and recessive retinal disorders. In addition, gene transfer of molecules with either neurotrophic or antiangiogenic properties provides useful alternatives to the classic gene replacement for treatment of both mendelian and complex traits affecting the retina. Years of successful rAAV-mediated gene transfer to the retina have resulted in restoration of vision in dogs affected with congenital blindness. This has paved the way to the first attempts at treating inherited retinal diseases in humans with rAAV. Although the results of rAAV clinical trials for non-retinal diseases give a warning that the outcome of viral-mediated gene transfer in humans may be different from that predicted based on results in other species, the immune privilege of the retina combined with the versatility of rAAV serotypes may ultimately provide the first successful treatment of human inherited diseases using rAAV.

Nuclear-Associated Plasmid, But Not Cell-Associated Plasmid, is Correlated With Transgene Expression in Cultured Mammalian Cells (2000)

Abstract Intracellular plasmid is rapidly incorporated into the nucleus of HeLa cells following cationic lipoplex transfection. CV1 cells are less effective in translocating plasmid to the nucleus and also express less transgene than HeLa cells. Cultured HeLa and CV1 cells and corresponding isolated nuclei were analyzed after transfection of a Cy3 labeled pGreenLantern plasmid (Cy3-pGL). Flow cytometry was used to measure both plasmid delivery and transgene expression from the plasmid encoding a CMV promoter driven green fluorescent protein. During transfection, HeLa cells rapidly incorporated the plasmid, reaching a maximum of 80% Cy3-pGL positive cells 8 hours post-transfection. The average Cy3-pGL positive HeLa cell contained approximately 2470 plasmid copies. 48% of the nuclei isolated from the transfected HeLa cells were positive for the plasmid marker after 8 hours. In contrast to HeLa cells, fewer CV1 cells and CV1 nuclei incorporated plasmid DNA with peak transfection occurring after 12 hours for 36% of the cells and after 8 hours for 12% of the nuclei. However, the average Cy3-pGL positive CV1 cell did not have a significantly different number of total cellular plasmid copies than the average positive HeLa cell. CV1 nuclei, however, had half as much plasmid as HeLa nuclei. HeLa cells are more efficient than CV1 cells at transporting plasmid from the cytoplasm to the nucleus. This study demonstrates the use of a novel quantitative method to study plasmid transport from the cytoplasm to nucleus and the effect on transgene expression.
Effect of smoking on inflammatory bowel disease: Is it disease or organ specific (2007)

Smoking is an important environmental factor in inflammatory bowel disease (IBD) with differing effects in ulcerative colitis (UC) and Crohn's disease (CD). Never smoking and formerly smoking increase the risk of UC, whereas smoking exacerbates the course of CD. The potential mechanisms involved in this dual relationship are yet unknown. A reasonable assumption is that smoking has different effects on the small and large intestine. This assumption is based on animal and human studies that show that the effects of smoking/nicotine on CD and UC depend on the site of inflammation and not on the type of disease.
Spatiotemporal amplitude-and-phase reconstruction by Fourier-transform of interference spectra of high-complex-beams (2010)

We propose what we believe to be a novel method to reconstruct the spatiotemporal amplitude and phase of the electric field of ultrashort laser pulses using spatially resolved spectral interferometry. This method is based on a fiber-optic coupler interferometer that has certain advantages in comparison with standard interferometer systems, such as being alignment-free and selection of the reference beam at a single point. Our technique, which we refer to as the SpatioTemporal Amplitude-and-phase Reconstruction by Fourier-transform of Interference Spectra of High-complex-beams, offers compactness and simplicity. We report its application to the experimental characterization of chirped pulses and to spatiotemporal reconstructions of a convergent beam as well as plane-plane and spherical-plane waves interferences, which we check with our simulations.
Two-port microwave amplification in long samples of gallium arsenide (1967)

Experiments on a new type of two-port, unilateral traveling-wave amplifier using subcritically doped GaAs specimens several space-charge wavelengths long are described. Net terminal gains of 2-4 dB are reported in the frequency range 700-1500 MHz. The gain is presently limited by inefficient coupling to the space-charge wave; the measured variation of phase delay between input and output terminals as a function of bias voltage is in good accord with theory, however.
Longitudinal diffusion MRI for treatment response assessment: Preliminary experience using an MRI‐guided tri‐cobalt 60 radiotherapy system (2016)

High Performance Solid Oxide Fuel Cell Cathode Fabricated by Electrochemical Vapor Deposition (1994)

cathodes have been investigated as high temperature oxygen reduction electrodes in the solid oxide fuel cells (SOFCs). The cathodes consist of 10 mole percent of yttria stabilized zirconia (YSZ) thin film electrolyte layer deposited on a porous tube using the electrochemical vapor deposition method. The cathodes have different electrochemical properties from those fabricated with the sintering method. The cathode polarization was about 1 mV at a current density of 1.5 A/cm2 in oxygen at 1000°C. This type of cathode has an extremely large phase boundary and large interfacial capacitance (more than 1 F/cm2) which is approximately proportional to the oxygen partial pressure.

In order to evaluate the effect of charge transfer and/or charge ordering in ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{MnO}}_{3}$ on the magnetic and transport properties, a library of $[({\mathrm{LaMnO}}_{3}{)}_{m}/({\mathrm{SrMnO}}_{3}{)}_{m}{]}_{n}$ superlattices have been fabricated by the combinatorial pulsed laser deposition method. The properties of superlattices were found to depend strongly on the periodicity m; superlattices of $m<~4$ behaved like a solid solution ${\mathrm{La}}_{0.5}{\mathrm{Sr}}_{0.5}{\mathrm{MnO}}_{3}$ film, while the superlattices of $m>4$ were significantly different from the solid solution. These superlattices exhibited a higher resistivity and lower Curie temperature than $m<~4$ superlattices. The results indicate that the properties of the superlattices are dominated not only by the magnetic interaction between the superlattice constituents but also by carrier ${(e}_{g}$ electrons) transfer thorough the superlattice interface. The contribution of carrier transfer is supported by the magnetoelectric properties of another library of $[({\mathrm{La}}_{0.8}{\mathrm{Sr}}_{0.2}{\mathrm{MnO}}_{3}{)}_{8}/({\mathrm{La}}_{0.2}{\mathrm{Sr}}_{0.8}{\mathrm{MnO}}_{3}{)}_{m}{]}_{12}$ superlattices. The A-site cation order can change both effective carrier concentration and magnetic interaction.
Improvement in High-Fat Diet-Induced Obesity and Body Fat Accumulation by a <i>Nelumbo nucifera</i> Leaf Flavonoid-Rich Extract in Mice (2010)

Diets high in fat lead to excessive lipid accumulation in adipose tissue, which is a crucial factor in the development of obesity, hepatitis, and hyperlipidemia. In this study, we investigated the antiobesity effect of a flavonoid-enriched extract from Nelumbo nucifera leaf (NLFE) in vivo. C57BL/6 mice were fed with a high-fat diet (HFD) to induce obesity. NLFE reduced the body weight, body lipid accumulation, and activities of fatty acid synthase (FAS), glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase. NLFE also suppressed the expression of FAS, acetyl-CoA carboxylase, and HMGCoA reductase and increased the phosphorylation of AMP-activated protein kinase in the liver. Taken together, we demonstrated that NLFE targets lipid-regulated enzymes and may be effective in attenuating body lipid accumulation and preventing obesity.
