Multiagent Low-Dimensional Linear Bandits (2022)

We study a multiagent stochastic linear bandit with side information, parameterized by an unknown vector <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\theta ^* \in \mathbb {R}^{d}$</tex-math></inline-formula> . The side information consists of a finite collection of low-dimensional subspaces, one of which contains <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\theta ^*$</tex-math></inline-formula> . In our setting, agents can collaborate to reduce regret by sending recommendations across a communication graph connecting them. We present a novel decentralized algorithm, where agents communicate subspace indices with each other and each agent plays a projected variant of LinUCB on the corresponding (low dimensional) subspace. By distributing the search for the optimal subspace across users and learning of the unknown vector by each agent in the corresponding low-dimensional subspace, we show that the per-agent finite-time regret is much smaller than the case when agents do not communicate. We finally complement these results through simulations.
West messa metal mapper data inversion and classification (2014)

In this paper, West Messa UXO classification results are presented for cued data collected by the Metal mapper sensor. Data sets are inverted using advanced forward EMI model called the orthonormalized volume magnetic source (ONVMS) model. All data are inverted as single, two and three sources. For each inversion, targets intrinsic parameters are extracted and used in a library matching technique. Anomalies are classified as targets of interest (TOI) and clutter.
TNF receptor I is required for induction of macrophage heat shock protein 70 (2001)

Expression of heat shock proteins (HSP) is an adaptive response to cellular stress. Stress induces tumor necrosis factor (TNF)-alpha production. In turn, TNF-alpha induces HSP70 expression. However, osmotic stress or ultraviolet radiation activates TNF-alpha receptor I (TNFR-I) in the absence of TNF-alpha. We postulated that TNF-alpha receptors are involved in the induction of HSP70 by cellular stress. Peritoneal Mphi were isolated from wild-type (WT), TNF-alpha knockout (KO), and TNFR (I or II) KO mice. Cells were cultured overnight and then heat stressed at 43 +/- 0.5 degrees C for 30 min followed by a 4-h recovery at 37 degrees C. Cellular HSP70 expression was induced by heat stress or exposure to endotoxin [lipopolysaccharide (LPS)] as determined by immunoblotting. HSP70 expression induced by either heat or LPS was markedly decreased in TNFR-I KO Mphi, whereas TNFR-II KO Mphi exhibited HSP70 expression comparable to that in WT mice. Expression of HSP70 after heat stress in TNF-alpha KO Mphi was also similar to that in WT mice, suggesting that induction of HSP70 by TNFR-I occurs independently of TNF-alpha. In addition, levels of steady-state HSP70 mRNA were similar by RT-PCR in WT and TNFR-I KO Mphi despite differences in protein expression. Furthermore, the effect of TNFR-I appears to be cell specific, since HSP70 expression in splenocytes isolated from TNFR-I KO was similar to that in WT splenocytes. These studies demonstrate that TNFR-I is required for the synthesis of HSP70 in stressed Mphi by a TNF-independent mechanism and support an intracellular role for TNFR-I.
High Resolution based Bearing Damage Identification in Poly Phase Asynchronous Motor using Gabor Transforms of Stator Current (2021)

This paper proposes an advanced fault detection technique for polyphase induction motor via motor current spectral analysis. In this, induction motor safety is of high priority due to its massive usage in industries worldwide. Their benefits like more reliable, cost-effective, robust, and more efficient, etc. The motor current is disengaged from the induction motor to get frequency domain analysis using Gabor Transforms(GT) good resolution technique. Moreover, the non-stationary nature of the stator current is tested with different speed conditions at loads 1 and 2. Mainly these methods are used to run over the resolution problems, which are analogous to current signature analysis. Here Gabor transform detects the faults and locates dominating frequencies of the induction motor. The proposed scheme is verified on a 1.5 KW induction motor experimentally.
Nanorod and Nanoparticle Shells in Concentration Gradient Core–Shell Lithium Oxides for Rechargeable Lithium Batteries (2014)

The structure, electrochemistry, and thermal stability of concentration gradient core-shell (CGCS) particles with different shell morphologies were evaluated and compared. We modified the shell morphology from nanoparticles to nanorods, because nanorods can result in a reduced surface area of the shell such that the outer shell would have less contact with the corrosive electrolyte, resulting in improved electrochemical properties. Electron microscopy studies coupled with electron probe X-ray micro-analysis revealed the presence of a concentration gradient shell consisting of nanoparticles and nanorods before and after thermal lithiation at high temperature. Rietveld refinement of the X-ray diffraction data and the chemical analysis results showed no variations of the lattice parameters and chemical compositions of both produced CGCS particles except for the degree of cation mixing (or exchange) in Li and transition metal layers. As anticipated, the dense nanorods present in the shell gave rise to a high tap density (2.5 g cm(-3) ) with a reduced pore volume and surface area. Intimate contact among the nanorods is likely to improve the resulting electric conductivity. As a result, the CGCS Li[Ni0.60 Co0.15 Mn0.25 ]O2 with the nanorod shell retained approximately 85.5% of its initial capacity over 150 cycles in the range of 2.7-4.5 V at 60 °C. The charged electrode consisting of Li0.16 [Ni0.60 Co0.15 Mn0.25 ]O2 CGCS particles with the nanorod shell also displayed a main exothermic reaction at 279.4 °C releasing 751.7 J g(-1) of heat. Due to the presence of the nanorod shell in the CGCS particles, the electrochemical and thermal properties are substantially superior to those of the CGCS particles with the nanoparticle shell.
Effect of Next Generation Computer Graphic Card Blower Fan Speed on Thermal Performance and Acoustic Noise With Psychoacoustic Metrics (2005)

Graphic Processor Units (GPUs) on the latest models of computer graphic cards generate significant amounts of heat. In fact, the required dissipation rate is so large that cooling fans mounted on heat-sinks must be used to maintain satisfactory GPU temperatures. The packaging of these fans is small and similar designs have been used for cooling of electronic packaging for decades. The appropriate application of these fans as well as their optimal design for minimal noise generation and maximum air movement has not kept pace with that of large industrial sized fans. Where space limitations allow and heat transfer requirements dictate, blower type fans are implemented because they are capable of delivering relatively high flow rates in high impedance environments when they are compared to more traditional axial flow fans. The operation of these blower fans, particularly at high speeds, results in the generation of noise which is experienced by the user. Both computer manufacturers and consumers alike have deemed this noise to be excessive and annoying. The fan model predictions and the operational reality of the higher fan speeds needed to deliver increased air flow both lead to the reality of higher noise levels. The purpose of this study was to experimentally investigate the realized thermal and acoustic performance of a blower style fan-sink mounted on an advanced graphics port (AGP) card. The goal of this investigation was to determine what thermal benefits of higher flow rate are realized by the blower fan at the expense of increased noise emissions. The experimental results of thermal measurement results spanning the operating speed of the fan are presented and accompanied by the noise data. These data include both traditional acoustic analysis techniques using sound pressure and power level measurements as well as psychoacoustic metrics. The result of the thermal testing suggests that the rate of improvement in thermal performance decreases as the blower fan speed increases. As expected, an increase in noise level was also observed. Of particular interest were the results of the psychoacoustic analysis which indicate a similar detrimental effect with increased fan speed for some metrics, while other metrics indicate no change across the operating speed range of the blower fan.

Spectroscopic characterization at THz frequencies of glucose-based biomaterials: paramylon, paramylon-ester and cellulose (2019)

The terahertz (THz) spectroscopy of paramylon (β-1,3-glucan) and paramylon-ester extracted from microalgae called as Euglena have been studied by Fourier Transform Infrared Spectrometer (FT-IR) in a frequency range from 0.3 to 9 THz. The absorption spectra of paramylon were analyzed by comparing them with cellulose that has a similar long-chain -(C6H10O5)n-structure with paramylon. The differences in absorption features between paramylon and cellulose may be caused by their different chain structures. The broad absorption spectra of paramylon-ester can be attributed to some sort of disorder of long-chain molecular vibration modes due to the substitution of propionyl chloride and long-chain acid chloride by esterification.
Learning sparse polynomials (2014)

We study the question of learning a sparse multi-variate polynomial over the real domain. In particular, for some unknown polynomial f(vx ) of degree-d and k monomials, we show how to reconstruct f, within error e, given only a set of examples bar xi drawn uniformly from the n-dimensional cube (or an n-dimensional Gaussian distribution), together with evaluations f(bar xi) on them. The result holds even in the “noisy setting”, where we have only values f(bar xi)+g where g is noise (say, modeled as a Gaussian random variable). The runtime of our algorithm is polynomial in n,k,1/e and Cd where Cd depends only on d. Note that, in contrast, in the “boolean version” of this problem, where bar x is drawn from the hypercube, the problem is at least as hard as the “noisy parity problem,” where we do not know how to break the nΩ(d) time barrier, even for k=1, and some believe it may be impossible to do so.
TOXICITY OF ORGANIC SELENIUM IN THE DIET TO CHINOOK SALMON (1990)

The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets contained fish meal made from high-selenium mosquitofish (Gambusia affinis Baird and Girard) collected from the selenium-laden San Luis Drain, California (here termed SLD diet) and the other contained meal made from low-selenium mosquitofish (collected from a reference site) fortified with selenomethionine. A 90-d study was conducted with swim-up larvae in a water-simulating dilution of San Luis Drain water in a standardized fresh water; and a 120-d study was conducted with fingerlings 70-mm long in a water of similar quality but prepared with a standardized brackish water. After 90 d of exposure in the freshwater study, survival was reduced in fish fed ≥9.6 μg Se/g of either diet, and growth was reduced in fish fed ≥5.3 μg Se/g of SLD diet or ≥18.2 μg Se/g of selenomethionine diet. Reduced fish growth, whole-body concentrations of selenium and survival were strongly correlated to concentrations of selenium in both diets. After 120 d of exposure in the brackish-water study, survival was unaffected but growth was reduced in fish fed ≥18.2 μg Se/g of SLD diet or 35.4 μg Se/g of selenomethionine diet. After 120 d of dietary exposure, survival during a 10-d seawater challenge test was reduced in fish fed 35.4 μg Se/g of either diet. In this second dietary study, concentration—response relations were observed in both dietary treatments between the dietary concentrations of selenium and all three characteristics — fish growth, whole-body concentrations of selenium and survival in seawater.
Mask CD correction method using dry-etch process (2006)

In this study, the method for achieving precise CD MTT (critical dimension mean to target) in manufacturing attenuated PSM (phase shift mask) was investigated. As the specification for photomask becomes tighter, more precise control of CD is required. There are several causes to result in CD MTT error. In general mask patterning processes which are from blank material to dry etch, it is difficult to detect CD MTT error before final CD measurement and correct it. It is necessary to apply new process to mask production to correct CD error and control CD MTT precisely. Reducing number of factors which can have an effect on CD and introducing reliable method to correct CD error are important to achieve accurate CD MTT. For the correction of CD error, the reliability of CD in each measurement step such as resist CD or Cr CD before and after resist removal and effect on items related with CD like CD uniformity, isolated-dense CD difference, etc should be considered and evaluated. In this method to correct CD MTT error, Cr CD after removing resist was measured before MoSiN dry etch and additional corrective Cr dry etch using Cr CD information was applied to cancel CD error and then MoSiN dry etch was followed. In this case, factors affecting final CD are additional corrective Cr etch and MoSiN etch. The relationship between CD shift and corrective Cr etch time for masks with various pattern densities was found and necessary corrective Cr etch time was applied to CD correction process. The CD MTT error is canceled by additional corrective Cr dry etch step. As a result, accurate CD control and significant decrease of CD MTT error for attenuated PSM is achieved through the use of this CD correction method.
Measurement of ϒ production in pp collisions at $\sqrt{\boldsymbol{s}}=\boldsymbol{7}~\mathrm{TeV}$ (2012)

The production of <i>ϒ</i>(1<i>S</i>), <i>ϒ</i>(2<i>S</i>) and <i>ϒ</i>(3<i>S</i>) mesons in proton-proton collisions at the centre-of-mass energy of [Formula: see text] is studied with the LHCb detector. The analysis is based on a data sample of 25 pb<sup>-1</sup> collected at the Large Hadron Collider. The <i>ϒ</i> mesons are reconstructed in the decay mode <i>ϒ</i>→<i>μ</i><sup>+</sup><i>μ</i><sup>-</sup> and the signal yields are extracted from a fit to the <i>μ</i><sup>+</sup><i>μ</i><sup>-</sup> invariant mass distributions. The differential production cross-sections times dimuon branching fractions are measured as a function of the <i>ϒ</i> transverse momentum <i>p</i><sub><i>T</i></sub> and rapidity <i>y</i>, over the range <i>p</i><sub><i>T</i></sub> <15 GeV/c and 2.0<<i>y</i><4.5. The cross-sections times branching fractions, integrated over these kinematic ranges, are measured to be [Formula: see text] where the first uncertainty is statistical, the second systematic and the third is due to the unknown polarisation of the three <i>ϒ</i> states.
7.1: Inverse Confocal Sensor Based on a Bidirectional OLED Display (2011)

Abstract Bidirectional OLED‐based microdisplays offer interesting possibilities for new applications. Light emission and detection is combined on one single chip by using OLED on CMOS technology. Such a chip has primarily been developed for optocouplers or photo‐electric barriers, but it offers interesting possibilities for other fields. A new optical concept of an inverse confocal sensor based on bidirectional OLED Display will be presented.
Solid-state NMR Study of Ion Adsorption and Charge Storage in Graphene Film Supercapacitor Electrodes (2016)

Graphene film has been demonstrated as promising active materials for electric double layer capacitors (EDLCs), mainly due to its excellent mechanical flexibility and freestanding morphology. In this work, the distribution and variation pattern of electrolyte ions in graphene-film based EDLC electrodes are investigated with a <sup>11</sup>B magic-angle spinning nuclear magnetic resonance (MAS-NMR) spectroscopy. For neutral graphene films soaked with different amounts of electrolytes (1 M TEABF<sub>4</sub>/ACN), weakly and strongly adsorbed anions are identified based on the resonances at different <sup>11</sup>B chemical shifts. Unlike other porous carbonaceous materials, the strongly adsorbed anions are found as the major electrolyte anions components in graphene films. Further measurements on the ion population upon charging are carried out with applying different charging voltages on the graphene films. Results indicate that the charging process of graphene-film based EDLCs can be divided into two distinct charge storage stages (i.e., ejection of co-ions and adsorption of counter-ions) for different voltages. The as-obtained results will be useful for the design and fabrication of high performance graphene-film based EDLCs.
Bandwidth Limitations in Characterization of High Intensity Focused Ultrasound Fields in the Presence of Shocks (2010)

Nonlinear propagation effects result in the formation of weak shocks in high intensity focused ultrasound (HIFU) fields. When shocks are present, the wave spectrum consists of hundreds of harmonics. In practice, shock waves are modeled using a finite number of harmonics and measured with hydrophones that have limited bandwidths. The goal of this work was to determine how many harmonics are necessary to model or measure peak pressures, intensity, and heat deposition rates of the HIFU fields. Numerical solutions of the Khokhlov‐Zabolotskaya‐Kuznetzov‐type (KZK) nonlinear parabolic equation were obtained using two independent algorithms, compared, and analyzed for nonlinear propagation in water, in gel phantom, and in tissue. Measurements were performed in the focus of the HIFU field in the same media using fiber optic probe hydrophones of various bandwidths. Experimental data were compared to the simulation results.

A Novel Bacteriophage Lysin-Human Defensin Fusion Protein Is Effective in Treatment of Clostridioides difficile Infection in Mice (2019)

<i>Clostridioides difficile</i> is the leading cause of worldwide antibiotics-associated diarrhea. In this study, we report the construction and evaluation of a novel bacteriophage lysin-human defensin fusion protein targeting <i>C. difficile</i>. The fusion protein, designated LHD, is composed of two parts connected by a 3-repeating unit linker "(GGGGS)<sub>3</sub>": the catalytic domain of a lysin protein from a <i>C. difficile</i> bacteriophage phiC2 (LCD), and the functional domain of a human defensin protein HD<sub>5</sub>. Lytic assays showed that LHD protein had a potent lytic activity against different types of clinical <i>C. difficile</i> strains, including the epidemic 027, 078, 012, and 087 strains. The minimum inhibitory concentration (MIC) of LHD was 0.78 μg/ml, which was lower than the MIC of the protein LCD (1.56 μg/ml), and the MICs of metronidazole (4 μg/ml) and vancomycin (4 μg/ml). In addition, the LHD protein could lyse <i>C. different</i> strains in different pHs (6.0, 7.0, and 8.0). Evaluation of LHD potency <i>in vivo</i> using mouse model of <i>C. difficile</i> infection (CDI) showed that administration of the LHD protein (twice daily for 7 days) was effective in mitigating the symptoms and reducing the death from CDI. Treatment with LHD also significantly decreased the number of <i>C. difficile</i> spores and the toxin level in feces from the infected mice. Our data suggest that this novel lysin-human defensin fusion protein has a potential on CDI control.
Intussusception-like phenomenon in acute type A aortic dissection (2011)

A 66-year-old man was hospitalized with signs of type A dissection and unstable conditions. The computed-tomography scan confirmed the diagnosis and, in the operating theater, a transesophageal echocardiogram showed an unexpected intussusception-like phenomenon: the intima of the ascending aorta prolapsed into the valve (see Fig. A Bentall procedure was performed successfully.
Probing Gut Participation in Parkinson’s Disease Pathology and Treatment via Stem Cell Therapy (2023)

Accumulating evidence suggests the critical role of the gut–brain axis (GBA) in Parkinson’s disease (PD) pathology and treatment. Recently, stem cell transplantation in transgenic PD mice further implicated the GBA’s contribution to the therapeutic effects of transplanted stem cells. In particular, intravenous transplantation of human umbilical-cord-blood-derived stem/progenitor cells and plasma reduced motor deficits, improved nigral dopaminergic neuronal survival, and dampened α-synuclein and inflammatory-relevant microbiota and cytokines in both the gut and brain of mouse and rat PD models. That the gut robustly responded to intravenously transplanted stem cells and prompted us to examine in the present study whether direct cell implantation into the gut of transgenic PD mice would enhance the therapeutic effects of stem cells. Contrary to our hypothesis, results revealed that intragut transplantation of stem cells exacerbated motor and gut motility deficits that corresponded with the aggravated expression of inflammatory microbiota, cytokines, and α-synuclein in both the gut and brain of transgenic PD mice. These results suggest that, while the GBA stands as a major source of inflammation in PD, targeting the gut directly for stem cell transplantation may not improve, but may even worsen, functional outcomes, likely due to the invasive approach exacerbating the already inflamed gut. The minimally invasive intravenous transplantation, which likely avoided worsening the inflammatory response of the gut, appears to be a more optimal cell delivery route to ameliorate PD symptoms.
