Notch: from neural development to neurological disorders (2008)

Notch is an integral membrane protein that functions as receptor for ligands such as jagged and delta that are associated with the surface of neighboring cells. Upon ligand binding, notch is proteolytically cleaved within its transmembrane domain by presenilin-1 (the enzymatic component of the gamma-secretase complex) resulting in the release of a notch intracellular domain which translocates to the nucleus where it regulates gene expression. Notch signaling plays multiple roles in the development of the CNS including regulating neural stem cell (NSC) proliferation, survival, self-renewal and differentiation. Notch is also present in post-mitotic neurons in the adult CNS wherein its activation influences structural and functional plasticity including processes involved in learning and memory. Recent findings suggest that notch signaling in neurons, glia, and NSCs may be involved in pathological changes that occur in disorders such as stroke, Alzheimer's disease and CNS tumors. Studies of animal models suggest the potential of agents that target notch signaling as therapeutic interventions for several different CNS disorders.
Characteristics of Geriatric Patients Seeking Medication Treatment for Pathologic Gambling Disorder (2001)

This study was constructed to compare geriatric patients seeking medication treatment for pathologic gambling disorder (PGD) with younger pathologic gamblers. This comparison study assessed three groups with PGD according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition: 16 subjects over the age of 60 years, 11 subjects between the ages of 20 and 30 years, and 46 subjects between the ages of 40 and 50 years. All subjects were evaluated in terms of demographic characteristics, clinical features of PGD, and treatment history. Geriatric gamblers had a later age of onset of gambling and developed pathologic gambling over a longer period of time. Geriatric subjects were more likely to play slot machines and demonstrate less variety in their choice of gambling activity. Geriatric gamblers were also more likely to gamble secondary to boredom. Geriatric subjects were as likely as the other age groups to report slight or no response to nonpharmacologic treatment. There appear to be some differences in the clinical features of PGD among geriatric subjects, and these differences may have treatment implications.
Key Capacity for Product Sources With Application to Stationary Gaussian Processes (2015)

We show that for product sources, rate splitting is optimal for secret key agreement using limited one-way communication between two terminals. This yields an alternative proof of the tensorization property of a strong data processing inequality originally studied by Erkip and Cover and amended recently by Anantharam et al. We derive a water-filling solution of the communication-rate-key-rate tradeoff for a wide class of discrete memoryless vector Gaussian sources which subsumes the case without an eavesdropper. Moreover, we derive an explicit formula for the maximum secret key per bit of communication for all discrete memoryless vector Gaussian sources using a tensorization property and a variation on the enhanced channel technique of Weingarten et al. Finally, a one-shot information spectrum achievability bound for key generation is proved from which we characterize the communication-rate-key-rate tradeoff for stationary Gaussian processes.
Human activity recognition using standard descriptors of MPEG CDVS (2017)

In this paper, a novel human activity recognition method is presented. The proposed solution uses a single stationary camera in order to detect common human activities like: hand waving, walking, running etc. Unlike other methods which use different kinds of characteristic point descriptors in order to describe human poses, the proposed solution uses a CDVS descriptor which is part of the MPEG-7 standard. This allows the efficient calculation of a compact descriptor in a camera. The main goal of this work is to propose an efficient application of CDVS to describe and recognize different human activities. The experiments were performed on the Weizmann and KTH datasets. The obtained results prove the high accuracy of human activity recognition system with CDVS.
Electrical transport along bacterial nanowires from Shewanella oneidensis MR-1 (2011)

Bacterial nanowires are extracellular appendages that have been suggested as pathways for electron transport in phylogenetically diverse microorganisms, including dissimilatory metal-reducing bacteria and photosynthetic cyanobacteria. However, there has been no evidence presented to demonstrate electron transport along the length of bacterial nanowires. Here we report electron transport measurements along individually addressed bacterial nanowires derived from electron-acceptor-limited cultures of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1. Transport along the bacterial nanowires was independently evaluated by two techniques: (i) nanofabricated electrodes patterned on top of individual nanowires, and (ii) conducting probe atomic force microscopy at various points along a single nanowire bridging a metallic electrode and the conductive atomic force microscopy tip. The S. oneidensis MR-1 nanowires were found to be electrically conductive along micrometer-length scales with electron transport rates up to 10/s at 100mV of applied bias and a measured resistivity on the order of 1 Ω·cm. Mutants deficient in genes for c-type decaheme cytochromes MtrC and OmcA produce appendages that are morphologically consistent with bacterial nanowires, but were found to be nonconductive. The measurements reported here allow for bacterial nanowires to serve as a viable microbial strategy for extracellular electron transport.

Structural defects cause TiO2-based photocatalysts to be active in visible light (2004)

Oxidation of TiO or Ti2O3 led to the formation of TiO2 with activity in visible light much higher than when TiN was used as a precursor, pointing out the importance of oxygen defects/vacancies for extension of activity of TiO2 into the visible region.

First Operation of AlGaN Channel High Electron Mobility Transistors (2007)

A channel layer substitution of a wider bandgap AlGaN for conventional GaN in high electron mobility transistors (HEMTs) is one possible method of enhancing the breakdown voltage for higher power operation. Wider bandgap AlGaN, however, should also increase the ohmic contact resistance. We utilized a Si ion implantation doping technique to achieve sufficiently low resistive source/drain contacts, and realized the first HEMT operation with an AlGaN channel layer. This result is very promising for the further higher power operation of high-frequency HEMTs.
Pilot allocation and receive antenna selection: A Markov decision theoretic approach (2013)

This paper considers antenna selection (AS) for packet reception at a receiver equipped with multiple antenna elements but only a single radio frequency chain. The receiver makes its AS decisions based on noisy channel estimates obtained from the training symbols (pilots). The time-correlation of the wireless channel and the results of the link-layer error checks upon data packet reception provide additional information that can be exploited for AS. This information can also be used to optimally distribute pilots among the antenna elements, so that packet loss due to selection errors is minimized. The task of the receiver, then, is to sequentially select (a) the pilot symbol allocation for channel estimation on each of the receive antennas and (b) the antenna to be used for data packet reception. The goal is to maximize the expected throughput, based on the history of allocation and selection decisions, and the corresponding noisy channel estimates and error check observations. This joint problem of pilot allocation and AS is solved as a partially observed Markov decision problem (POMDP) and the solutions yield the optimal policies that maximize the long-term expected throughput. The performance of the POMDP solution is compared with several other schemes for a 2-state Markov channel model, and it is illustrated that it outperforms the others.
Toward perfect on-wafer pattern placement: stitched overlay exposure tool characterization (2010)

Continued lithographic pattern density scaling depends on aggressive overlay error reduction.<sup>1,2</sup> Double patterning processes planned for the 22nm node require overlay tolerances below 5 nm; at which point even sub-nanometer contributions must be considered. In this paper we highlight the need to characterize and control the single-layer matching among the three pattern placement mechanisms intrinsic to step&scan exposure - optical imaging, mask-to- wafer scanning, and field-to-field stepping. Without stable and near-perfect pattern placement on each layer, nanometer-scale layer-to-layer overlay tolerance is not likely to be achieved. Our approach to understanding onwafer pattern placement is based on the well-known technique of stitched field overlay. We analyze dense sampling around the field perimeter to partition the systematic contributors to pattern placement error on representative dry and immersion exposure tools.
Intracellular proteolytic activity of cathepsin B is associated with capillary‐like tube formation by endothelial cells in vitro (2005)

The lysosomal cysteine protease cathepsin B is implicated in degradation of extracellular matrix (ECM), a crucial step in a variety of physiological and pathological processes, including tumor dissemination and angiogenesis. In this study, we analyzed the contribution of extracellular and intracellular cathepsin B activity on the formation of capillary-like tubular structures by human umbilical vein endothelial cells (HUVECs) grown on Matrigel matrix, using general and specific cysteine protease inhibitors. We demonstrated, by confocal assay using quenched fluorescent protein substrate DQ-collagen IV, that endothelial cells degrade ECM both intracellularly and pericellularly. Intracellular cathepsin B activity detected by degradation of Z-Arg-Arg cresyl violet substrate was co-localized with the products of DQ-collagen IV degradation in the perinuclear region and in the capillary-like tubular structures. Treatment of cells with membrane-permeable CA-074 Me effectively abolished intracellular cathepsin B activity, and resulted in reduced tube length (32.3+/-9.4% at 10 microM), total tubule area (49.6+/-12.4% at 10 microM), and the number of branch points of tubules (47.5+/-7.7% at 10 microM) in a dose-dependent manner. In contrast, CA-074 (0.1-10 microM), a membrane-impermeable cathepsin B specific inhibitor, general cysteine protease inhibitors chicken cystatin (5 microM) and E-64 (10 microM), and the metalloprotease inhibitor Minocycline (10 microM) showed no significant inhibitory effect in our angiogenesis model. These results show that, besides multiple regulatory molecules, intracellular cathepsin B also contributes to the neovascularization process and should be considered as a potential therapeutic target.
High-power red beam generation by frequency-doubling of a Nd:YAG laser (1999)

This letter reports the generation of 6.1 W of red laser radiation by frequency-doubling a Nd:YAG laser operating at a wavelength of 1.319 /spl mu/m with a KTP crystal. The conversion efficiency and the stability of the red output power were both improved through the suppression by means of a thin etalon of two-wavelength operation in the 1.3-/spl mu/m region.

Optimization of EHL Lubrication Performance in Thrust Slide-Bearings of Scroll Compressors (2014)

The proteasome plays essential roles in nearly all biological processes in plant defense and development, yet simple methods for displaying proteasome activities in extracts and living tissues are not available to plant science. Here, we introduce an easy and robust method to simultaneously display the activities of all three catalytic proteasome subunits in plant extracts or living plant tissues. The method is based on a membrane-permeable, small-molecule fluorescent probe that irreversibly reacts with the catalytic site of the proteasome catalytic subunits in an activity-dependent manner. Activities can be quantified from fluorescent protein gels and used to study proteasome activities in vitro and in vivo. We demonstrate that proteasome catalytic subunits can be selectively inhibited by aldehyde-based inhibitors, including the notorious caspase-3 inhibitor DEVD. Furthermore, we show that the proteasome activity, but not its abundance, is significantly increased in Arabidopsis upon treatment with benzothiadiazole (BTH). This upregulation of proteasome activity depends on NPR1, and occurs mostly in the cytoplasm. The simplicity, robustness and versatility of this method will make this method widely applicable in plant science.
Alternative chromophores for use in light-activated surgical adhesives (2003)

A study was conducted to determine the feasibility of using alternative chromophores in light-activated surgical adhesives. Two commonly used chromophores, indocyanine green (ICG), and methylene blue (MB) were investigated, as well as three different food colorings: red #40, blue #1, and green food coloring consisting of yellow #5 and blue #1. The study consisted of three components. First, the absorption profiles of the five chromophores, both diluted in deionized water and bound to protein, were recorded with a UV-Vis-NIR spectrophotometer. Second, the effect of accumulated thermal dosages on the stability of the absorption profiles was investigated. Third, the stability of the absorption profiles of the chromophore solutions when exposed to ambient light for an extended period of time was investigated. The peak absorption wavelengths of ICG, MB, red #40, and blue #1, were found to be 780 nm, 665 nm, 500 nm, and 630 nm respectively. The green food coloring had two absorption peaks at 417 nm and 630 nm, corresponding to the two dye components comprising this color. The peak absorption wavelength of the ICG shifted to 805 nm when bound to protein. ICG and MB showed a significant decrease in absorbance units with increased time and temperature when heated to temperatures up to 100 degrees C. Negligible change in absorption with accumulated thermal dose was observed for any of the three food colorings investigated. Photobleaching was observed in both ICG and MB solutions with exposure to a white light source. An 88% decrease in absorption was seen in ICG deionized water solution after 7 days of exposure with a corresponding 33% decrease in absorption seen in the MB deionized water solution. A negligible drop in absorption was observed from exposure to ambient light for a 12-week period with the three food colorings investigated.

Effect of Inhaled Furosemide on Metabisulfite- and Methacholine-induced Bronchoconstriction and Nasal Potential Difference in Asthmatic Subjects (1990)

To evaluate the hypothesis that furosemide inhibits indirect bronchoconstrictor challenges by altering airway epithelial ion transport, we studied its effects on indirect bronchoconstriction induced by inhaled metabisulfite (MBS) and nasal potential difference (PD) in seven subjects with mild asthma. Its effect on direct bronchoconstriction by the inhaled muscarinic agonist methacholine (MC) was studied in six of these subjects. Each subject inhaled furosemide, 30 mg, in a randomized, double-blind, placebo-controlled fashion immediately before challenge with MBS (0.3 to 160 mg/ml in increasing doubling concentrations) and, in another study, MC (0.125 to 32 mg/ml) aerosols from a nebulizer attached to a dosimeter. PC20MBS and PC20MC, the concentration of each agent needed to lower FEV1 by 20%, were calculated by linear interpolation of the log dose-response curves. Furosemide had no effect on resting lung function, but it caused a significant threefold reduction in sensitivity to MBS (PC20MBS: GM +/- GSEM, 15.1 +/- 1.6 mg/ml after placebo and 40.7 +/- 1.7 mg/ml after furosemide; p less than 0.001) with a protective index of 64.8 +/- 10.7%. Furosemide caused no change in sensitivity to MC (PC20 MC:GM +/- GSEM, 2.37 +/- 1.61 mg/ml after placebo and 2.19 +/- 1.751 mg/ml after furosemide; NS). In a third study, furosemide, 30 mg, and placebo were inhaled through the nose in a randomized double-blind fashion immediately prior to inhalation of a PC20 concentration of MBS through the nose. Nasal PD was measured before and after placebo or furosemide, and again after MBS inhalation.(ABSTRACT TRUNCATED AT 250 WORDS)
Closed-Form Outage Probability and BER of MIMO Zero-Forcing Receiver in the Presence of Imperfect CSI (2006)

Zero-forcing (ZF) detection is a simple and effective technique for retrieving multiple transmitted data streams at the receiver in multiple-input multiple-output (MIMO) wireless antenna systems. However the detection requires accurate channel state information (CSI) which may not be available in practice. In this paper, the impact of imperfect CSI on the performance of MIMO ZF receiver over uncorrelated Rayleigh flat fading channel is analytically assessed. In particular, tight approximation of the post-processing SNR distribution is derived and system performance in terms of outage probability and the BER of MPSK modulation is obtained in closed-form. The tightness of our analytical approximation is verified by the simulation results
