Multi-view Wireless Video Streaming Based on Compressed Sensing (2015)

Multi-view wireless video streaming has the potential to enable a new generation of efficient and low-power pervasive surveillance systems that can capture scenes of interest from multiple perspectives, at higher resolution, and with lower energy consumption. However, state-of-the-art multi-view coding architectures require relatively complex predictive encoders, thus resulting in high processing complexity and power requirements. To address these challenges, we consider a wireless video surveillance scenario and propose a new encoding and decoding architecture for multi-view video systems based on Compressed Sensing (CS) principles, composed of cooperative sparsity-aware block-level rate-adaptive encoders, feedback channels and independent decoders. The proposed architecture leverages the properties of CS to overcome many limitations of traditional encoding techniques, specifically massive storage requirements and high computational complexity. It also uses estimates of image sparsity to perform efficient rate adaptation and effectively exploit inter-view correlation at the encoder side.
Combining Growth Hormone-Releasing Hormone Antagonist With Luteinizing Hormone-Releasing Hormone Antagonist Greatly Augments Benign Prostatic Hyperplasia Shrinkage (2012)

A combination of growth hormone-releasing hormone antagonist with luteinizing hormone-releasing hormone antagonist potentiated a reduction in prostate weight in an experimental benign prostatic hyperplasia model. Results suggest that this shrinkage in prostate volume was induced by the direct inhibitory effects of growth hormone-releasing hormone and luteinizing hormone-releasing hormone antagonists exerted through their respective prostatic receptors. These findings suggest that growth hormone-releasing hormone antagonists and/or their combination with luteinizing hormone-releasing hormone antagonists should be considered for further development as therapy for benign prostatic hyperplasia.
Fault detection system design based on a new trade-off strategy (2002)

Problems related to fault detection in dynamic systems with unknown inputs are studied. Instead of designing fault detection systems from the viewpoint of increasing the system robustness against unknown inputs and the sensitivity to the faults, an approach is proposed, which allows us to design fault detection systems based on a trade-off between the false alarm rate and the missed detection rate. A further study on the relationships between the approach proposed and the existing H/sub 2/, H/sub /spl infin///spl infin// and H/sub /spl infin//min/ optimization approaches demonstrates that the approach proposed in the paper provides us not only with a unified solution to the existing approaches but also with the best solution among these approaches in view of minimizing the missed detection rate under a given false alarm rate.
Perpendicular Magnetic Anisotropy of Co-Au Multilayers Induced by Interface Sharpening (1988)

Co-Au multilayers with Co layer thicknesses between 22 and 5 \AA{}A, prepared by ion-beam sputtering, have an easy-plane magnetic anisotropy. Their saturation magnetization indicates the presence of diffuse interfaces, caused by ion-beam mixing. Annealing of the multilayers at 250-300\ifmmode^\circ\else\textdegree\fi{}C leads to a perpendicular anisotropy for Co thicknesses below about 14 \AA{}A. This effect is attributed to a stronlgy enhanced interface anisotropy, which is due to sharpening of the interfaces as revealed by x-ray diffraction.
Collision detection for deforming necklaces (2002)

In this paper, we propose to study deformable necklaces --- flexible chains of balls, called beads, in which only adjacent balls may intersect. Such objects can be used to model macro-molecules, muscles, rope, and other 'linear' objects in the physical world. In this paper, we exploit this linearity to develop geometric structures associated with necklaces that are useful in physical simulations. We show how these structures can be implemented efficiently and maintained under necklace deformation. In particular, we study a bounding volume hierarchy based on spheres built on a necklace. Such a hierarchy is easy to compute and is suitable for maintenance when the necklace deforms, as our theoretical and experimental results show. This hierarchy can be used for collision and self-collision detection. In particular, we achieve an upper bound of O(nlog n) in two dimensions and O(n 2-2/d) in d-dimensions, d 3, for collision checking. To our knowledge, this is the first sub-quadratic bound proved for a collision detection algorithm using predefined hierarchies. In addition, we show that the power diagram, with the help of some additional mechanisms, can be also used to detect self-collisions of a necklace in certain ways complementary to the sphere hierarchy.
Estimation of convergence of iterative method for solution of the Cauchy problem for the 3D Navier - Stokes equations (2011)

Some known results regarding the Euler and Navier-Stokes equations were obtained by different authors. Existence and smoothness of solutions for the Navier-Stokes equations in two dimensions have been known for a long time. Leray showed that the Navier-Stokes equations in three space dimensions have a weak solution. Scheffer and Shnirelman obtained weak solution of the Euler equations with compact support in spacetime. Caffarelli, Kohn and Nirenberg improved Scheffer's results, and F.-H. Lin simplified the proof of the results of J. Leray. Many problems and conjectures about behavior of weak solutions of the Euler and Navier-Stokes equations are described in the books of Bertozzi and Majda, Constantin or Lemarie-Rieusset. Solutions of the Navier-Stokes and Euler equations with initial conditions (Cauchy problem) for 2D and 3D cases were obtained in the convergence series form by analytical iterative method using Fourier and Laplace transforms in paper $\cite{TT10}$. These solutions were received in a form of infinitely differentiable functions, and that allows us to analyze all aspects of the problem on a much deeper level and with more details. Also such smooth solutions satisfy the conditions required in $\cite{CF06}$ for the problem of Navier-Stokes equations. For several combinations of problem parameters numerical results were obtained and presented as graphs $\cite{TT10}$,$\;\cite{TT11}$. This paper describes detailed proof of convergence of the analitical iterative method for solution of the Cauchy problem for the 3D Navier - Stokes equations. The convergence is shown for wide ranges of the problem's parameters. Estimated formula for the border of convergence area of the iterative process in the space of system parameters is obtained. Also we have provided justification of the analytical iterative method solution for Cauchy problem for the 3D Navier-Stokes equations.
Mini-hemagglutinin vaccination induces cross-reactive antibodies in pre-exposed NHP that protect mice against lethal influenza challenge (2018)

Seasonal vaccines are currently the most effective countermeasure against influenza. However, seasonal vaccines are only effective against strains closely related to the influenza strains contained in the vaccine. Recently a new hemagglutinin (HA) stem-based antigen, the so-called "mini-HA", has been shown to induce a cross-protective immune response in influenza-naive mice and non-human primates (NHP). However, prior exposure to influenza can have a profound effect on the immune response to subsequent influenza infection and the protective efficacy of vaccination. Here we show that mini-HA, compared to a trivalent influenza vaccine (TIV), elicits a broadened influenza-specific humoral immune response in NHP previously exposed to influenza. Serum transfer experiments showed that antibodies induced by both mini-HA and seasonal vaccine protected mice against lethal challenge with a H1N1 influenza strain heterologous to the H1 HA included in the TIV. However, antibodies elicited by mini-HA showed an additional benefit of protecting mice against lethal heterosubtypic H5N1 influenza challenge, associated with H5 HA-specific functional antibodies.
Characterization of Molecular Structure of Emulsion Acrylic Microgels: Exploring the Impact of Molar Mass on Coating Properties of Self-Cross-Linkable Latexes (2016)

Self-cross-linkable latexes of core–shell microgel particles were synthesized by the emulsion polymerization of acrylic monomers. The molar mass of copolymers forming the shell layer was gradually reduced by isooctyl 3-mercaptopropionate included in the synthesis of the shell layers. The molar mass distribution of latex particles was determined using size exclusion chromatography and asymmetric flow field-flow fractionation, respectively, both separation methods being coupled with a multiangle light scattering detector. The results confirmed theoretical predictions and described empirically the effects of molar mass of the shell layer copolymer on decreasing the minimum film-forming temperature and influencing the end-use properties of coatings.
Tyrosine phosphorylation is not a relevant mechanism to modulate aquaporin 2 activity in gestational queen endometrium and placenta (2020)

Aquaporins have been shown to be regulated by phosphorylation of serine residues, but the possible role of tyrosine residues phosphorylation has not been evaluated. Changes in the localization of aquaporin 2 (AQP2) in the queen endometrium have been related to serum progesterone levels. The aim of this study was to determine whether these AQP2-localization changes are mediated by variations in its tyrosine phosphorylation levels. Twelve queens were included in the study and divided into (a) non-macroscopically pregnant with low levels of progesterone; (b) non-macroscopically pregnant with high levels of progesterone; (c) 30 days of pregnancy; and (d) 60 days of pregnancy. Samples from endometrium and placental transference zone were obtained, immunoprecipitated and analysed by immunoblotting to determine the abundance of AQP2 and its relative levels of tyrosine phosphorylation. No significant differences in the tyrosine phosphorylation levels of immunoprecipated-AQP2 were observed between groups. We can thus conclude that changes in the localization of AQP2 in the queen endometrium are not modulated by tyrosine phosphorylation.
HEPATORENAL SYNDROME (1997)

National data would suggest a survival benefit of combined LKTx over isolated LTx for those patients with poor renal function, specifically those with HRS, whereas our center's results suggest otherwise. Unfortunately, we could not identify any preoperative risk factors in the HRS patients, or in the broader group of patients with renal insufficiency at our center, that would indicate the need for future renal transplantation. We believe that HRS patients can be successfully managed with isolated LTx.
1H-nuclear magnetic resonance deoxymyoglobin signal as indicator of intracellular oxygenation in myocardium (1991)

We report in this study that the intracellular oxygenation state is measurable with the 1H nuclear magnetic resonance signal of the proximal histidine N delta H proton of deoxymyoglobin. The signal appears in a clear spectral region of the 1H spectrum and is sensitive to various hypoxic and ischemic conditions. In perfused heart, the deoxymyoglobin's response to tissue oxygenation precedes the one reflected in the 31P phosphocreatine or ATP signals, suggesting that oxidative energy metabolism is still sufficient even when the myoglobin is partially saturated with oxygen. Our method offers then a unique way to observe tissue oxygenation and its interaction in localized tissue region in vivo.
MTX Treatment Does Not Improve Outcome in Mice with AMI (2020)

MTX medication did not improve postischemic cardiac damage in a murine model of AMI. Future trials are needed to identify and investigate other anti-inflammatory targets to improve cardiovascular outcome.
Retinyl methyl ether down-regulates activator protein 1 transcriptional activation in breast cancer cells. (1997)

Retinyl methyl ether (RME) is known to prevent the development of mammary cancer. However, the mechanism by which RME exerts its anticancer effect is presently unclear. The diverse biological functions of retinoids, the vitamin A derivatives, are mainly mediated by their nuclear receptors, retinoic acid receptors (RARs) and retinoid X receptors (RXRs). RARs and RXRs are ligand-dependent transcriptional factors that either activate gene transcription through their binding to retinoic acid response elements or repress transactivation of genes containing the activator protein 1 (AP-1) binding site. Previous studies demonstrated that RME can modulate transcriptional activity of retinoid receptors on retinoic acid response elements, suggesting that regulation of retinoid receptor activity may mediate the anticancer effect of RME. In this study, we present evidence that RME can down-regulate AP-1 activity induced by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate, insulin, growth factors, and the nuclear proto-oncogenes c-Jun and c-Fos. Transient transfection assays demonstrate that inhibition of AP-1 activity occurs on the human collagenase promoter containing an AP-1 binding site or the thymidine kinase promoter linked with an AP-1 binding site. In HeLa cells, the inhibition is observed when RAR-alpha and/or RXR-alpha but not RAR-beta or RAR-gamma expression vectors are cotransfected, whereas the endogenous retinoid receptors in breast cancer cells T-47D and ZR-75-1 were sufficient to confer the inhibition by RME. Furthermore, using gel retardation assay, we show that 12-O-tetradecanoylphorbol-13-acetate- and epidermal growth factor-induced AP-1 binding activity in breast cancer cells is inhibited by RME. These results suggest that one of the mechanisms by which RME prevents cancer development may be due to the repression of AP-1-responsive genes.
Preparation of Polyimide Nanofibers by Electrospinning (2006)

Polyimide nanofibers were obtained by electrospinning a solution of poly(amic acid)(PAA), a precursor of polyimide(PI) prepared in the laboratory, in dimethylacetamide(DMAc) at 14kV, followed by thermal imidization. Mechanical property of the resulting nanofiber non-woven membranes was investigated by tensile tests. Chemical structure and surface morphology of the non-woven mats were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) as well as atomic force microscope (AFM) respectively
A telephone-based directory assistance system adaptively trained using minimum classification error/generalized probabilistic descent (2002)

The minimum classification error/generalized probabilistic descent (MCE/GPD) framework has been applied to several recognizer frameworks, such as hidden Markov models, prototype based systems, and systems based on artificial neural networks. However, to our knowledge, the MCE/CPD framework has not yet been applied to a working online speech recognition system in a realistic application environment. We describe the application of MCE/GPD to a telephone-based multi-speaker speech recognition system that accepts spoken Japanese names and forwards calls to any of up to 400 staff members. Points of interest include the automatic collection and labeling of new training data and the use of MCE/GPD training to improve recognizer performance.
Towards mathematical modelling in security risk management in system engineering (2013)

This paper addresses the potential of mathematical modeling in support of the current security risk management approach in SESAR. One of the key challenges in large-scale system engineering for security is to provide support for system-wide implementation of security controls with limited resources. For this purpose resource-intensive security risk assessment shall only be applied to top priority concepts and technological enablers. Furthermore, robust mathematical concepts can support the refinement of security risk management decision during the engineering process through the verification of previously identified security controls and associated what-if simulations. This research developed a method based on game-theoretic concepts and graph theory. The risk mitigation decision-making problem is modeled as a multi-objective optimization problem. The goal of the research is to identify and explore the underlying mathematical concepts and apply them to a use case within the SESAR context validating the methodology and mathematical modeling approach. This paper presents the conceptual building blocks. the validation use-case, and the associated results and lessons learnt. The results from this preliminary study show that the approach can be used to complement the existing SESAR security risk assessment method. This allows for the verification of expert judgments and what-if considerations on the basis of alternating parameters or assumptions.

Handheld Flyback driven coaxial dielectric barrier discharge: Development and characterization (2008)

The development of a handheld single and triple chamber atmospheric pressure coaxial dielectric barrier discharge driven by Flyback circuitry for helium and argon discharges is described. The Flyback uses external metal-oxide-semiconductor field-effect transistor power switching technology and the transformer operates in the continuous current mode to convert a continuous dc power of 10-33 W to generate a 1.2-1.6 kV 3.5 micros pulse. An argon discharge breakdown voltage of approximately 768 V is measured. With a 50 kHz, pulse repetition rate and an argon flow rate of 0.5-10 argon slm (slm denotes standard liters per minute), the electrical power density deposited in the volume discharge increases linearly at a rate of 75+/-20% mW/cm(3) per 1 slm of gas. Electrical power transfer efficiency between the secondary Flyback coil and the discharge volume increases from 0.1% to 0.65%. Neutral argon gas forced convection analysis yields a similar energy loss rate to the electrical discharge process. Optical emission spectroscopy studies of the expanding discharge plume into ambient air reveal that the air climatically controls the plume chemistry to produce an abundance of neutral argon atoms and molecular nitrogen.
Overexpression of snapdragon Delila (Del) gene in tobacco enhances anthocyanin accumulation and abiotic stress tolerance (2017)

We propose that Del overexpression elevates transcript levels of anthocyanin biosynthetic and antioxidant-related genes, leading to enhanced anthocyanin production and antioxidant activity. The resultant increase of anthocyanin and antioxidant activity improves abiotic stress tolerance.
Characterization of endothelial argininosuccinate synthase subcellular localization and protein interactions relevant to the function of the citrulline‐nitric oxide cycle (2009)

Argininosuccinate synthase (AS) is an essential mediator of endothelial health by providing a dedicated source of arginine for nitric oxide (NO) production and promoting endothelial cell viability. Our laboratory has previously demonstrated that AS is present in endothelial caveolar fractions along with endothelial nitric oxide synthase (eNOS) and argininosuccinate lyase (AL), the core components of the citrulline‐NO cycle. To expand on those studies, we utilized immunofluorescence microscopy and showed that AS localized to the Golgi, perinuclear region and plasma membrane in conjunction with eNOS. We also demonstrated that AS co‐localizes with caveolin‐1 and HSP90, key regulators of eNOS function. Co‐immunoprecipitation studies showed that AS interacts with caveolin‐1 and HSP90. In the case of caveolin‐1, a binding motif in the AS protein sequence suggested a direct interaction. To characterize the nitric oxide metabolome from a more global perspective, we utilized co‐immunoprecipitation followed by mass spectrometry to identify several putative AS and eNOS interacting partners that are either novel or understudied in the regulation of NO production. Our work highlights the functional co‐localization and interactions of citrulline‐NO cycle components in vascular endothelial cells, which has important implications for our understanding of vascular biology.
Peak Power Scaling of a Multi-kHz, Picosecond, DPSS MOPA System for OPCPA Pumping (2013)

We address the peak power scaling of our DPSS MOPA system from 10 MW to &gt;100 MW (anticipated) at multi-kHz for OPCPA pumping. We discuss the challenges in scaling this Nd-based picosecond amplifier system.
Effects of V-skew on the cogging torque in permanent magnet synchronous motor (2013)

In this paper, we proposed how the V-skew applied on a magnet of the rotor to improve the characteristics of cogging torque in large PMSM. Large PMSM is difficult to apply a pitch of the diagonal magnetic skew because of the motor's structure and making. In addition, the force in the direction of z-axis occurs when the diagonal skew is applied. So we are applying the optimal v-skew to reduce torque ripple and cogging torque because this reduces the noise and vibration on the motor. Through FEM 3D analysis, we studied to find the optimal v-skew angle for reducing torque ripple.
