Improving Person Re-identification via Pose-Aware Multi-shot Matching (2016)

Person re-identification is the problem of recognizing people across images or videos from non-overlapping views. Although there has been much progress in person re-identification for the last decade, it still remains a challenging task because of severe appearance changes of a person due to diverse camera viewpoints and person poses. In this paper, we propose a novel framework for person reidentification by analyzing camera viewpoints and person poses, so-called Pose-aware Multi-shot Matching (PaMM), which robustly estimates target poses and efficiently conducts multi-shot matching based on the target pose information. Experimental results using public person reidentification datasets show that the proposed methods are promising for person re-identification under diverse viewpoints and pose variances.
Schiff Base Metal Complexes of Chromium(III), Manganese(III), Iron(III), Oxovanadium(IV), Zirconium(IV) and Dioxouranium(VI) (2003)

The Schiff base 2,5-dihydroxyacetophenone isonicotinoyl hydrazone (H 2 L) has been synthesized by condensation of 2,5-dihydroxyacetophenone with isonicotinoyl hydrazide in ethanol. Metal complexes of the Schiff base were prepared from salts of Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO 2 (VI). Characterization of the ligand and its metal complexes were carried out by elemental analysis, molar conductivity, magnetic susceptibility measurements, IR, 1 H NMR, electronic and thermogravimetric analysis in air. The Schiff base behaves as flexidentate ligand and commonly coordinates through the oxygen atom ofthe deprotonated phenolic group and the nitrogen atom of azomethine group. The thermal data have been analyzed for the kinetic parameters by Broido and Horowitz-Metzger methods. All the compounds were also screened for their antimicrobial activity by agar cup-plate method against various organisms and the results have been compared.

Retrograde Response to Mitochondrial Dysfunction Is Separable from TOR1/2 Regulation of Retrograde Gene Expression (2005)

Retrograde (RTG) signaling senses mitochondrial dysfunction and initiates readjustments of carbohydrate and nitrogen metabolism through nuclear accumulation of the heterodimeric transcription factors, Rtg1/3p. The RTG pathway is also linked to target of rapamycin (TOR) signaling, among whose activities is transcriptional control of nitrogen catabolite repression (NCR)-sensitive genes. To investigate the connections between these two signaling pathways, we have analyzed rapamycin sensitivity of the expression of the RTG target gene CIT2 and of two NCR-sensitive genes, GLN1 and DAL5, in respiratory-competent (rho+) and -incompetent (rho0) yeast cells. Here we have presented evidence that retrograde gene expression is separable from TOR regulation of RTG- and NCR-responsive genes. We showed that expression of these two classes of genes is differentially regulated by glutamate starvation whether in response to mitochondrial dysfunction or induced by rapamycin treatment, as well by glutamine or histidine starvation. We also showed that Lst8p, a component of the TOR1/2 complexes and a negative regulator of the RTG pathway, has multiple roles in the regulation of RTG- and NCR-sensitive genes. Lst8p negatively regulates CIT2 and GLN1 expression, whereas DAL5 expression is independent of Lst8p function. DAL5 expression depends on the GATA transcription factors Gln3p and Gat1p. Gat1p is translocated to the nucleus only upon TOR inhibition by rapamycin. Altogether, these data show that Rtg1/3p, Gln3p, and Gat1p can be differentially regulated through different nutrient-sensing pathways, such as TOR and retrograde signaling, and by multiple factors, such as Lst8p, which is suggested to have a role in connecting the RTG and TOR pathways.
Harmonic blue light generation in bulk periodicallypoled MgO:LiNbO <sub>3</sub> (1996)

A periodically domain-inverted structure for a first-order bulk quasi-phasematched second harmonic generation was fabricated in a 0.3 mm thick MgO:LiNbO3 crystal via the application of a high-voltage pulse. A blue output power of 1 mW was achieved with 330 mW of fundamental infrared light in a single pass through the 10 mm interaction length.
Determination of Propagation Constant of Terahertz Dielectric Ridge Waveguide Using Noncontact Measurement Approach (2017)

This paper presents a detailed uncertainty analysis and tolerance analysis of the noncontact measurement approach proposed here for determining the propagation constant of the dielectric ridge waveguide (DRW), operating in 750-1000-GHz range. Two diagonal horns were used to guide the terahertz wave through the DRW without physical contact. The experimental procedure is described in detail in this paper. The expanded uncertainty estimates were determined for this noncontact measurement for the first time. The uncertainty of the propagation constant of DRW includes measurement uncertainty and truncation uncertainty. The truncation uncertainty is based on the error of a simplified calculated equation, used in determining the propagation constant of the DRW. A detailed uncertainty budget of the propagation constant is presented. The tolerance analysis shows that the measurement approach is insensitive to the misalignment of the experimental system.
Dynamic load balancing across mirrored multimedia servers (2003)

The purpose of this paper is to present protocols for efficient load balancing across replicated multimedia servers in a metropolitan area network. Current multimedia infrastructures, even when they use mirrored servers, do not have standardized load balancing schemes. Existing schemes frequently require participation from the clients in balancing the load across the servers efficiently. We propose two protocols in this paper for fair load balancing without any client-side processing being required. Neither protocol requires any change to the network-level infrastructure. Using network packet loss and packet transmission delay as the chief metrics, we show the effectiveness of the protocols through extensive simulations.
β-Ga<sub>2</sub>O<sub>3</sub>and single-crystal phosphors for high-brightness white LEDs and LDs, and β-Ga<sub>2</sub>O<sub>3</sub>potential for next generation of power devices (2014)

<i>β</i>-Ga<sub>2</sub>O<sub>3</sub> is the most transparent conductive oxide, well known since several decades for its large bandgap of 4.8 eV. Its potential as semiconductor material, however, is just emerging in recent years. Present work shows the development of <i>β</i>Ga<sub>2</sub>O<sub>3</sub> for semiconductor applications and its current state-of-the-art. The discussion is focused on three different aspects: (1) Advantageous growth from melt of large-size <i>β</i>-Ga<sub>2</sub>O<sub>3</sub>single-crystals. High-crystalline quality and carrier control make possible the production of conductive and semi-insulating wafers. (2) <i>β</i>-Ga<sub>2</sub>O<sub>3</sub>as substrate for homoepitaxy as well as for heteroepitaxial deposition of GaN-based devices. High-brightness blue-LEDs with vertical current injection are demonstrated. (3) Potential of <i>β</i>-Ga<sub>2</sub>O<sub>3</sub>for high-power devices with higher breakdown voltage than GaN and SiC counterparts. The first Schottky barrier diode is shown, as well as first transistors (MESFET and MOSFET) are indicated. Single-crystal phosphors are introduced as novel alternative to currently used powder phosphors. In connection with high-brightness white light-sources, based on LEDs or LDs plus phosphor converters, single-crystal phosphors possess advantageous features. These avoid the use of resins and exhibit a very high internal quantum efficiency, which remains stable with the temperature increase.
Color constancy from multispectral images (2003)

This paper describes a computational method for estimating the body reflectance function of color surfaces. The experimental apparatus consists of a vision system having seven spectral channels whose wavelength sensitivities cover the visible spectrum. The estimation of the spectral-reflectance function is based on finite-dimensional linear models. In order to use digitized imaged data to evaluate the surface reflectance, a procedure for bypassing the problem of unknown illuminant spectral-power distribution was devised. For the simple objects utilized (color checker charts), it is found that an accuracy greater than 97% can be achieved.
Three-port power electronic system for energy storage and recovery using a parallel connection of a power factor corrector boost and a dual active bridge (2012)

The increasing demand of an intermediate storage of electrical energy in battery systems, in particular due to the use of renewable energy, has resulted in the need of more intelligent power supply systems. Bidirectional DC/DC power converters with galvanic isolation and efficient and low harmonic distortion AC/DC conversion to connect the mains line to the load are usually required in multiple applications. In this paper a three-port power supply system which interconnects the single-phase line with both an active load and a battery is proposed. Considering the specifications of a particular application, different topologies for the power supply system have been analyzed. After a theoretical evaluation, the optimum of the studied configurations has been developed and tested in all modes of operation demanded by the application. To accomplish all the requirements of the different operation modes of the power supply system, digital control has been used to control the bidirectional converter and the global system.

Outcomes research studies. (1996)

The outcomes movement has its roots in studies conducted in the 1970s and '80s, which showed that there was substantial geographic variability in medical practice in the United States and that such variability was driven by nonmedical factors. Outcomes management has several key components: the development and implementation of guidelines; measurement, pooling, and dissemination of clinical and outcomes data; and refinement of guidelines based on analysis of those data. Cancer has lagged behind many other areas of medicine in pursuing outcomes research and management. The National Comprehensive Cancer Network (NCCN) has made a commitment to perform outcomes research within its member institutions and has begun to pool and analyze selected patterns of care and outcomes data. The network's ultimate goal is the creation of a uniform outcomes measurement system to monitor guideline compliance.
Mechanism of β-Adrenergic Receptor Desensitization in Cardiac Hypertrophy Is Increased β-Adrenergic Receptor Kinase (1997)

Pressure overload cardiac hypertrophy in the mouse was achieved following 7 days of transverse aortic constriction. This was associated with marked beta-adrenergic receptor (beta-AR) desensitization in vivo, as determined by a blunted inotropic response to dobutamine. Extracts from hypertrophied hearts had approximately 3-fold increase in cytosolic and membrane G protein-coupled receptor kinase (GRK) activity. Incubation with specific monoclonal antibodies to inhibit different GRK subtypes showed that the increase in activity could be attributed predominately to the beta-adrenergic receptor kinase (betaARK). Although overexpression of a betaARK inhibitor in hearts of transgenic mice did not alter the development of cardiac hypertrophy, the beta-AR desensitization associated with pressure overload hypertrophy was prevented. To determine whether the induction of betaARK occurred because of a generalized response to cellular hypertrophy, betaARK activity was measured in transgenic mice homozygous for oncogenic ras overexpression in the heart. Despite marked cardiac hypertrophy, no difference in betaARK activity was found in these mice overexpressing oncogenic ras compared with controls. Taken together, these data suggest that betaARK is a central molecule involved in alterations of beta-AR signaling in pressure overload hypertrophy. The mechanism for the increase in betaARK activity appears not to be related to the induction of cellular hypertrophy but to possibly be related to neurohumoral activation.
High speed analog-to-digital conversion with silicon photonics (2009)

Sampling rates of high-performance electronic analog-to-digital converters (ADC) are fundamentally limited by the timing jitter of the electronic clock. This limit is overcome in photonic ADC's by taking advantage of the ultra-low timing jitter of femtosecond lasers. We have developed designs and strategies for a photonic ADC that is capable of 40 GSa/s at a resolution of 8 bits. This system requires a femtosecond laser with a repetition rate of 2 GHz and timing jitter less than 20 fs. In addition to a femtosecond laser this system calls for the integration of a number of photonic components including: a broadband modulator, optical filter banks, and photodetectors. Using silicon-on-insulator (SOI) as the platform we have fabricated these individual components. The silicon optical modulator is based on a Mach-Zehnder interferometer architecture and achieves a V<sub>π</sub>L of 2 Vcm. The filter banks comprise 40 second-order microring-resonator filters with a channel spacing of 80 GHz. For the photodetectors we are exploring ion-bombarded silicon waveguide detectors and germanium films epitaxially grown on silicon utilizing a process that minimizes the defect density.
Effects of Dietary Supplements on Space Radiation-Induced Oxidative Stress in Sprague-Dawley Rats (2004)

Of particular concern for the health of astronauts during space travel is radiation from protons and high-mass, high-atomic-number (Z), and high-energy particles (HZE particles). Space radiation is known to induce oxidative stress in astronauts after extended space flight. In the present study, the total antioxidant status was used as a biomarker to evaluate oxidative stress induced by gamma rays, protons and HZE-particle radiation. The results demonstrate that the plasma level of total antioxidants in Sprague-Dawley rats was significantly decreased (P < 0.01) in a dose-dependent manner within 4 h after exposure to gamma rays. Exposure to protons and HZE-particle radiation also significantly decreased the serum or plasma level of total antioxidants in the irradiated animals. Diet supplementation with L-selenomethionine alone or a combination of selected antioxidant agents was shown to partially or completely prevent the decrease in the serum or plasma levels of total antioxidants in animals exposed to gamma rays, protons or HZE particles. These findings suggest that exposure to space radiation may compromise the capacity of the host antioxidant defense and that this adverse biological effect can be prevented at least partially by dietary supplementation with L-selenomethionine and antioxidants.

#Sleepyteens: Social media use in adolescence is associated with poor sleep quality, anxiety, depression and low self‐esteem (2016)

This study examined how social media use related to sleep quality, self-esteem, anxiety and depression in 467 Scottish adolescents. We measured overall social media use, nighttime-specific social media use, emotional investment in social media, sleep quality, self-esteem and levels of anxiety and depression. Adolescents who used social media more - both overall and at night - and those who were more emotionally invested in social media experienced poorer sleep quality, lower self-esteem and higher levels of anxiety and depression. Nighttime-specific social media use predicted poorer sleep quality after controlling for anxiety, depression and self-esteem. These findings contribute to the growing body of evidence that social media use is related to various aspects of wellbeing in adolescents. In addition, our results indicate that nighttime-specific social media use and emotional investment in social media are two important factors that merit further investigation in relation to adolescent sleep and wellbeing.
