A Novel Query Caching Scheme for Dynamic InfiniBand Subnets (2015)

In large InfiniBand subnets the Subnet Manager (SM) is a potential bottleneck. When an InfiniBand subnet grows in size, the number of paths between hosts increases polynomials and the SM may not be able to serve the network in a timely manner when many concurrent path resolution requests are received. This scalability challenge is further amplified in a dynamic virtualized cloud environment. When a Virtual Machine (VM) with InfiniBand interconnect live migrates, the VM addresses change. These address changes result in additional load to the SM as communicating peers send Subnet Administration (SA) path record queries to the SM to resolve new path characteristics. In this paper we benchmark OpenSM to empirically demonstrate the SM scalability problems. Then we show that our novel SA Path Record Query caching scheme significantly reduces the load towards the SM. In particular, we show by using the Reliable Datagram Socket protocol that only a single initial SA path query is needed per communicating peer, independent of any subsequent (re)connection attempts.
The transient internal probe: A novel method for measuring internal magnetic field profilesa) (1995)

The transient internal probe (TIP) diagnostic is designed to permit internal magnetic field measurements in hot, high density plasmas. A small probe is fired through the plasma at high velocities and magnetic field measurements are accomplished using Faraday rotation within the Verdet glass probe. Magnetic field resolution of ±40 G and spatial resolution of 5 mm have been achieved. System frequency response is 10 MHz. Ablative effects are avoided by minimizing both the probe size and the time the probe spends in the plasma. A two-stage light-gas gun is used to accelerate the probe (held by a sabot) to 2.2 km/s. The sabot is removed using gas dynamic forces and a gas interface system prevents the helium muzzle gas from entering the plasma chamber. Work is underway to integrate the TIP diagnostic with laboratory plasma experiments.
A Calibration service for 30 MHz attenuation and phase shift (1988)

Calibrations and related measurement services of the National Bureau of Standards (NBS) provide the means for industry, government agencies, academia, and others to relate the measurements they make to national standards and, by extension, to the measurement systems of other countries throughout the world.
Costimulation of T cell receptor/CD3-mediated activation of resting human CD4+ T cells by leukocyte function-associated antigen-1 ligand intercellular cell adhesion molecule-1 involves prolonged inositol phospholipid hydrolysis and sustained increase of intracellular Ca2+ levels (1992)

Activation of resting human CD4+ T cells mediated by mAb ligation of the TCR/CD3 complex requires costimulatory signals to result in proliferation; these can be provided by intercellular cell adhesion molecule-1 (ICAM-1, CD54) a natural ligand of leukocyte function-associated Ag-1 (LFA-1, CD11a/CD18). We analyzed early signaling events involved in T cell activation to determine the contribution by the LFA-1/ICAM-1 interaction. We studied in detail the hydrolysis of phosphatidylinositol(4,5)bisphosphate and intracellular levels of free Ca2+ during stimulation with beads coated with the CD3 mAb OKT3 alone or in combination with purified ICAM-1 protein. Our investigations show no response to LFA-1/ICAM-1 alone, but that costimulation by LFA-1/CAM-1 interaction induces prolonged inositol phospholipid hydrolysis (up to 4 h), resulting in generation of both inositol(1,4,5)phosphate3 and inositol(1,3,4,5)phosphate4 and their derivatives. Based on studies with cycloheximide, this costimulatory effect of prolonged inositol phospholipid hydrolysis appears dependent in part on de novo protein synthesis. A sustained increase in intracellular levels of free Ca2+ level is also observed after LFA-1/ICAM-1 costimulation, which is at least partly dependent on extracellular sources of Ca2+. Kinetic studies indicate that costimulation requires a minimal period of 4 h of LFA-1/ICAM-1 interaction to provide maximal costimulation for OKT3-mediated T cell proliferation. Thus, the necessary costimulation required for OKT3-mediated proliferation in this model system may be provided by an extended LFA-1/ICAM-1 interaction that in combination with OKT3 mAb leads to signal-transducing events, resulting in prolonged phospholipase C activation and phosphatidylinositol(4,5)bisphosphate hydrolysis, and a sustained increase in intracellular levels of free Ca2+.
Случай внутрипросветного эндоскопического ушивания перфорации желудка (2014)

Medical footwear provides solutions for structural or functional foot problems. Individuals with normal feet do not require medical footwear. In diabetic patients with neuropathy and foot deformity, the use of medical footwear protects the foot, reduces the plantar pressures and significantly reduces the rate of ulcers formation and amputations. Shoes have different designs, heights, and may be constructed of differing materials depending upon the nature of the needed corrections. Structurally, shoes can be viewed as consisting of a sole and an upper portion. Both these entities can be further sub-divided into components and shapes, each one providing a different corrective feature. Ordering medical footwear requires the same specificity as with the provision of medications. In Israel, shoes are provided by the Ministry of Health to patients according to specific criteria. The provision and quality control is conducted through a selected panel of doctors, chosen by the Lewis National Institute of Rehabilitation, and working in public hospitals.

Microscopic processes during ultra-fast laser generation of Frenkel defects in diamond (2021)

Engineering single atomic defects into wide bandgap materials has become an attractive field\nin recent years due to emerging applications such as solid-state quantum bits and sensors. The\nsimplest atomic-scale defect is the lattice vacancy which is often a constituent part of more complex\ndefects such as the nitrogen-vacancy (NV) centre in diamond, therefore an understanding of the\nformation mechanisms and precision engineering of vacancies is desirable. We present a theoretical\nand experimental study into the ultra-fast laser generation of vacancy-interstitial pairs (Frenkel\ndefects) in diamond. In a range of other materials, Frenkel defect formation has previously been\nlinked to the recombination of laser generated excitonic states, however the mechanism in diamond\nis currently unknown and to date no quantitative agreement has been found between experiment\nand theory. Here, we find that a model for Frenkel defect generation via the recombination of\na bound biexciton as the electron plasma cools provides good agreement with experimental data.\nThe process is described by a set of coupled rate equations of the pulsed laser interaction with the\nmaterial and of the non-equilibrium dynamics of charge carriers during and in the wake of the pulse.
Balloon Incision of the Prostate: Preliminary Evaluation of a Minimally Invasive Technique (1991)

Balloon dilation to 60F at 2 atm for 15 minutes in 17 dogs was compared with the Acucise balloon dilation (50F) and incision catheter in 13 dogs. In the dilation group, the change in urethral width was +8% both acutely and at 12 weeks. In the Acucise-treated group, there was an increase in urethral diameter of 70% acutely and 47% at 12 weeks. Complications from use of the Acucise were one acute urinoma and one acute periprostatic hematoma. The authors discuss the drawbacks of the canine model of prostatic enlargement but note that the results of this trial were sufficiently impressive to warrant clinical trials, which are now in progress.
Large-scale image annotation using visual synset (2011)

We address the problem of large-scale annotation of web images. Our approach is based on the concept of visual synset, which is an organization of images which are visually-similar and semantically-related. Each visual synset represents a single prototypical visual concept, and has an associated set of weighted annotations. Linear SVM's are utilized to predict the visual synset membership for unseen image examples, and a weighted voting rule is used to construct a ranked list of predicted annotations from a set of visual synsets. We demonstrate that visual synsets lead to better performance than standard methods on a new annotation database containing more than 200 million images and 300 thousand annotations, which is the largest ever reported.
Heat treatment of ZnO nanoparticles: new methods to achieve high-purity nanoparticles for high-voltage applications (2015)

New methods based on orientation and coating of ZnO nanoparticles were attempted in order to remove crystal defects and pores without undesirable grain/particle sintering during heat treatment.
Discovery of a junctional epitope antibody that stabilizes IL-6 and gp80 protein:protein interaction and modulates its downstream signaling (2017)

Protein:protein interactions are fundamental in living organism homeostasis. Here we introduce VHH6, a junctional epitope antibody capable of specifically recognizing a neo-epitope when two proteins interact, albeit transiently, to form a complex. Orthogonal biophysical techniques have been used to prove the "junctional epitope" nature of VHH6, a camelid single domain antibody recognizing the IL-6-gp80 complex but not the individual components alone. X-ray crystallography, HDX-MS and SPR analysis confirmed that the CDR regions of VHH6 interact simultaneously with IL-6 and gp80, locking the two proteins together. At the cellular level, VHH6 was able to alter the response of endothelial cells to exogenous IL-6, promoting a sustained STAT3 phosphorylation signal, an accumulation of IL-6 in vesicles and an overall pro-inflammatory phenotype supported further by transcriptomic analysis. Junctional epitope antibodies, like VHH6, not only offer new opportunities in screening and structure-aided drug discovery, but could also be exploited as therapeutics to modulate complex protein:protein interactions.
Studies of Hemicellulase System in Aspergillus niger -Purification and Characterization of ${\beta}$- xylosidase- (1983)

-xylosidase(1,4-B-D-xulan xylohydrolase EC3,2,1,37) from Aspergillus niger KG79 was purified and characterized. The optimum pH and temperature of the enzyme were 3.5 and 65C, respectively. The enzyme was relatively stable between pH 2.5 and 6.0 at 60C. The molecular weight of the enzyme was estimated to be 480,000 composed of four identical subunit of 128,000. The enzyme appears to be a glycoprotein containing 22.5% of carbohydrate. It was not affected at all by heavy metals including mercuric ion, and reducing agents such as mercaptoethanol and sodium borohydride. The modification of carboxyl groups revealed that it was essential for its activity. It was noted that -xylosidase was located within the cells whereas D-xylanase was an extracellular enzyme. -Xylosidase was competitively inhibited by its reaction product, D-xylose. The dissociation constant of the product was 2.8mM, while Km was 0.23mM. -xylosidase by itself hydrolyzed commercial xylan and barley straw xylan into xylose to the degree of 14% and 20%, respectively, in term of reducing sugar.
Influence of a NbN overlayer on Nb/Al–AlOx/Nb high quality Josephson tunnel junctions for x-ray detection (1995)

Nb/Al–AlOx/Nb–NbN Josephson junctions for use as x-ray detectors have been fabricated. The NbN overlayer has been used to realize the trapping of quasiparticles in the Nb top layer with an increase of the charge collection efficiency. The temperature dependence of quasiparticle and Josephson critical current have been investigated and compared with that without a NbN overlayer, showing low leakage currents, about 200 pA (V=0.5 mV, T=0.67 K, A=20×20 μm2), and high dynamical resistances in the subgap region. Preliminary measurements under 6 keV x-ray irradiation have shown an increased value of the maximum collected charge.

Online Monitoring of Capacitance and Dissipation Factor of Motor Stator Winding Insulation During Accelerated Life Testing (2018)

Offline dissipation factor testing is one of the standard approaches to examine the condition of ac motor's stator winding insulation. An online technique to continuously monitor the condition of the groundwall and phase-to-phase insulation for ac machine stator windings insulation has been proposed. Dissipation factor and capacitance can be accurately monitored online based on the differential leakage current measurements for each phase. To further investigate the relationship between dissipation factor and the condition of stator winding insulation, an online high-voltage life testing is conducted on medium-voltage stator coils. The dissipation factor of the stator coils is continuously monitored online during such testing. The experimental results show that the dissipation factor can reliably reflect the health condition of stator winding coil insulation, and therefore can potentially be used for online monitoring the condition of stator winding insulation of ac machines. As an initial attempt to monitor dissipation factor during insulation life testing, the results presented in this paper are of great importance for future development work towards novel online monitoring technologies for rotating machines.
The dopamine uptake inhibitor, WIN 35,428, has sigma2 receptor agonist effects that contribute to its self‐administration (848.10) (2014)

Sigma receptors (σRs) are intracellular chaperone proteins implicated in several diseases, as well as psychiatric disorders and drug abuse. Several in vivo studies show blockade with σR antagonists of several cocaine effects, though not its self administration (SA). The present study assessed whether that insensitivity was specific to cocaine SA using the dopamine uptake inhibitors (WIN35,428, methylphenidate, nomifensine) in rats trained with cocaine SA. As with cocaine, σR antagonists (BD 1008, BD 1047, BD 1063, SN 79, SN 167, (±)SM 21, CM 304, CM 398) were ineffective against methylphenidate and nomifensine SA across a range of doses that antagonized SA of σR agonists (DTG, PRE 084, (+)pentazocine). In contrast, all antagonists tested, except CM 304 produced dose dependent insurmountable antagonism of WIN35,428 SA. CM 304 was equipotent in blocking the SA of DTG, (+)‐pentazocine, and PRE‐084, but only marginally potent in blocking SA of WIN35,428. The antagonists SN 79, SN 167, CM 398, and (±)SM 21 were more potent in blocking DTG than either PRE 084 or (+)pentazocine SA. These antagonists also blocked WIN35,428 SA, though three fold less potently than against DTG. The results are consistent with σR radioligand binding data for WIN35,428, the nonselective σ 1/2 R agonist effects of DTG, selective σ 1 R antagonist effects of CM 304, and that WIN 35,428 has σ 2 R agonist effects that contribute to its self administration.

Developmental differences in the contractile response of isolated ovine tracheal smooth muscle cells (2009)

Previous studies have shown developmental differences in smooth muscle tone of the airways. Differences in airway mechanics may be based upon cellular differences between animals of different ages. We developed a method [Driska et al. J Appl Physiol 86(1): 427-35, 1999] for isolating ovine tracheal smooth muscle cells and for measuring shortening velocity. This technique was used to study the change in contractile response of the airway smooth muscle (ASM) cell during development. Here we report differences between preterm (PT) (110-124 or 125-140 days post-conception), newborn (NB) (3-7 days postnatal) and adult (9-36 months) cells. These cells were compared with respect to morphometry, shortening velocity, and percent shortening. The neonatal cells were shorter and narrower than the adult cells. Maximum shortening velocity was faster for adult (45.1 microm/sec) than for neonatal cells (range 11.1-25.1 microm/sec). When velocity was normalized to the cell length, there was no difference between the adult and PT cells, but there was a significant difference between the NB (0.30 sec(-1)) and adult (0.54 sec(-1)) cells. The percent shortening did not show any significant difference with age. Within the neonatal groups, there were no significant differences in morphometry, shortening or velocity. To facilitate comparison between ASM tissues of different sizes with different sized cells, we also expressed percent shortening and velocities relative to a hypothetical 1 mm segment of tissue. Represented this way, the amount of shortening for all age groups was the same, but the predicted maximum velocity of the hypothetical PT tissue (125-140 days) was significantly greater than for NB.

Polymer Derived Ceramics with β‐Eucryptite Fillers: Filler‐Matrix Interactions (2017)

Polymer derived ceramics with ß‐eucryptite are manufactured and filler‐matrix interactions in the temperature range between 800 and 1 100 °C are investigated. Pyrolysis temperatures above 1 000 °C led to changes of the β‐eucryptite phase, due to a significant SiO 2 amount in the polymer derived ceramic matrix. A new phase, β‐spodumene, is formed; this is, confirmed by calculations of the lattice parameters. Scanning electron microscopy and energy dispersive x‐ray spectroscopy of the microstructure allow to localize spots on the matrix‐filler interface, where the described processes appear.
An Unsupervised Indoor Localization Method Based on Received Signal Strength (RSS) Measurements (2014)

We propose an unsupervised, received signal strength (RSS)- based indoor localization method, which as an infrastructure uses commercial WiFi chipsets and does not require any changes in the existing hardware. The method relies on path loss model for measured RSS levels where path loss coefficient is treated as a discrete random variable which takes values from some finite alphabet. The unknown location and path loss coefficient corresponding to each access point are jointly estimated using the Expectation Maximization (EM) approach. The algorithm is experimentally tested in an office space area of dimensions 32-by-52 m (1600 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) with only five access points and the achieved average localization error is below 4.5 m.
Disruption of the Gene Homologous to MammalianNramp1inMycobacterium tuberculosisDoes Not Affect Virulence in Mice (2002)

Natural-resistance-associated macrophage protein 1 (Nramp1) is a divalent cation transporter belonging to a family of transporter proteins highly conserved in eukaryotes and prokaryotes. Mammalian and bacterial transporters may compete for essential metal ions during mycobacterial infections. The mycobacterial Nramp homolog may therefore be involved in Mycobacterium tuberculosis virulence. Here, we investigated this possibility by inactivating the M. tuberculosis Nramp1 gene (Mramp) by allelic exchange mutagenesis. Disruption of Mramp did not affect the extracellular growth of bacteria under standard conditions. However, the Mramp mutation was associated with growth impairment under conditions of limited iron availability. The Mramp mutant displayed no impairment of growth or survival in macrophages derived from mouse bone marrow or in Nramp1(+/+) and Nramp1(-/-) congenic murine macrophage cell lines. Following intravenous challenge in BALB/c mice, counts of parental and Mramp mutant strains were similar in the lungs and spleens of the animals at all time points studied. These results indicate that Mramp does not contribute to the virulence of M. tuberculosis in mice.
