Анализ влияния неодномерных эффектов на отпирающий ток управления тиристорных структур на основе 4H-SiC (2017)

Рассмотрено влияние неодномерных эффектов, обусловленных растеканием тока управления в базовом слое, на величину отпирающего тока управления тиристоров на основе 4H-SiC. Показано, что реализующийся в 4H-SiC тиристорах новый механизм переключения приводит к зависимости отпирающего тока управления от параметров тиристора, качественно отличающейся от соответствующей зависимости в традиционных кремниевых тиристорах.

CudaDMA (2011)

As the computational power of GPUs continues to scale with Moore's Law, an increasing number of applications are becoming limited by memory bandwidth. We propose an approach for programming GPUs with tightly-coupled specialized DMA warps for performing memory transfers between on-chip and off-chip memories. Separate DMA warps improve memory bandwidth utilization by better exploiting available memory-level parallelism and by leveraging efficient inter-warp producer-consumer synchronization mechanisms. DMA warps also improve programmer productivity by decoupling the need for thread array shapes to match data layout. To illustrate the benefits of this approach, we present an extensible API, CudaDMA, that encapsulates synchronization and common sequential and strided data transfer patterns. Using CudaDMA, we demonstrate speedup of up to 1.37x on representative synthetic microbenchmarks, and 1.15x-3.2x on several kernels from scientific applications written in CUDA running on NVIDIA Fermi GPUs.
CFD Based Sensitivity Study of Cooling Performance of Transformer Radiators (2019)

Based on computational fluid dynamics (CFD) the cooling performance of a typical radiator bank of a liquid-immersed power transformer has been analyzed. The inefficiencies of the original (standard) design have been identified in relation to the unfavorable characteristics of the air flowing through the radiator. Several design changes have been assessed numerically by computing their impact on the cooling capacity of the radiator. This article presents the cooling performance of some of these design solutions, including changes in the radiator panel heights and the addition of a chimney at the top of the radiator. Details of the CFD model are presented along with the air flow patterns and cooling capacities of the enhanced designs compared to the original one.

Current integrating receivers for high speed system interconnects (2002)

This paper presents a high speed receiver design that utilizes current integration in order to increase its noise immunity. The integration of current on a capacitor based on the incoming signal voltage effectively averages the incoming signal over its valid time period, therefore filtering out high frequency noise. An experimental design illustrating the concept has been fabricated in a 1.2 /spl mu/m CMOS technology. The receiver dissipates 2.7 mW of power operating from a 5-V supply, achieves error free operation at a clock frequency of 250 MHz, and occupies 60/spl times/450 /spl mu/m/sup 2/ of silicon area.
Multicast VPN State Damping (2016)

This document describes procedures to damp Multicast VPN (MVPN) routing state changes and control the effect of the churn due to the multicast dynamicity in customer sites. The procedures described in this document are applicable to BGP-based multicast VPN and help avoid uncontrolled control-plane load increase in the core routing infrastructure. The new procedures proposed were inspired by BGP unicast route damping principles that have been adapted to multicast.
Short-Term Indwelling Foley Catheters Do Not Reduce the Risk of Postoperative Urinary Retention in Uncomplicated Primary THA and TKA (2022)

Background: The purpose of this randomized controlled trial was to determine whether a short-term Foley catheter (inserted in the operating room and removed upon arrival to the orthopaedic floor) would reduce the risk of postoperative urinary retention (POUR) in patients undergoing primary total hip (THA) and total knee arthroplasty (TKA). Methods: Three hundred and eighty-eight patients undergoing inpatient primary TKA (n = 228) or THA (n = 160) with spinal anesthesia were randomized to receive a short-term Foley catheter (n = 194) or no Foley (n = 194). There were 143 male and 245 female patients. The primary outcome was POUR, defined as requiring ≥2 straight catheterizations or the placement of an indwelling urinary catheter when indicated by retention of ≥450 mL on bladder scans. Secondary outcomes included urinary tract infections (UTIs) within 3 weeks and the need for ≥1 straight catheterization. A power analysis determined that 194 patients per group were required to detect a 7% minimal clinically important difference in POUR rates at 80% power and alpha of 0.05. Intention-to-treat and as-treated analyses were performed (2 patients received the non-allocated treatment). Outcomes were compared between the groups using univariate and multivariate analyses, with alpha &lt; 0.05. Results: Nine patients developed POUR: 4 in the short-term Foley group and 5 in the control group (2.1% versus 2.6%; p = 1.00). Of those who developed POUR, 8 were male and 1 was female (88.9% versus 11.1%; p = 0.002). Twenty-four patients required ≥1 straight catheterization: 10 in the Foley group and 14 in the control group (5.2% versus 7.2%; p = 0.40). Four patients developed UTIs: 3 in the Foley group and 1 in the control group (1.5% versus 0.5%; p = 0.62) on intention-to-treat analysis, and 4 in the Foley group and none in the control group (2.1% versus 0.0%; p = 0.12) on as-treated analysis. Conclusions: The use of a short-term Foley catheter inserted in the operating room and removed on arrival to the orthopaedic floor does not decrease the rate of POUR.

XPS investigations on the formation of passive layers on Fe/Si alloys at pH 5 and 9 (1999)

Binary Fe/Si alloys (2–25 at.% Si) were passivated potentiostatically in an alkaline (pH 9.0) and an acidic (pH 5.0) electrolyte. The specimens were sputter-cleaned and passivated under a protecting purified argon atmosphere and finally transferred into the ultrahigh vacuum of an ESCA spectrometer without contact with the laboratory atmosphere. X-ray photoelectron spectroscopy provides qualitative and quantitative information about the chemical composition and structure of the passive layers. Systematic variation of the passivation time in the range of milliseconds to hours at a low and a high potential yields insight into the mechanism of the formation of protecting passive layers on the examined Fe/Si alloys. The growth of the passive layers starts with the oxidation of Si, followed by the formation of Fe(II) which finally oxidizes to Fe(III). Depending on the Si content of the alloys and the pH, a protecting SiO2 layer or an Fe(III) oxide layer may form. Small amounts of Si (2–10 at. %) prevent the formation of a stable passive layer in acidic solutions by iron silicate formation, so that none of the cations may form a continuous protecting passive film. An Si content of >20 at.% clearly improves the passivation behaviour again. Copyright © 1999 John Wiley & Sons, Ltd.
Dynamics of Charge Transport through Osmium Tris Dimethoxy Bipyridyl Solid Deposits (2002)

Solid deposits of [Os(OMe-bpy)3](PF6)2 have been formed on a platinum microelectrode, where OMe-bpy is 4,4‘-dimethoxy, 2-2‘-dipyridyl. The voltammetry associated with the Os2+/3+ redox processes is nearly ideal where the supporting electrolyte is 0.1 M HClO4 and suggests that the redox centers within the deposits are solvated. Scanning electron microscopy reveals that prior to voltammetric cycling, the deposits exist as an array of microscopic particles. In contrast, after voltammetric cycling in perchloric acid the deposit becomes microcrystalline in the form of thin plates. Electrocrystallization is not observed when the deposits are cycled in neutral electrolyte suggesting that protonation of the methoxy groups plays an important role in the process. Where the supporting electrolyte is HClO4, voltammetry conducted under semi-infinite linear diffusion conditions yields a homogeneous charge transport diffusion coefficient, DCT, of 1.5 ± 0.1 × 10-9 cm2 s-1 for 0.1 ≤ [HClO4] ≤ 0.6 M. In contrast, above 0.6 M HClO4 DCT increases significantly reaching 13 ± 1 × 10-9 cm2 s-1 in 1.0 M HClO4. Analysis of these data according to the Dahms−Ruff equation yields a self-exchange rate constant of 5.7 × 106 M-1 s-1. High scan rate voltammetry, 5 ≤ υ ≤ 100 V s-1, has been used to determine the standard heterogeneous electron transfer rate constant, k°, as 1.0 ± 0.05 × 10-4 and 6.1 ± 0.2 × 10-5 cm s-1 for solid and solution phase, respectively.

Methods for Isolation and Identification of Nanoparticle-Containing Subcellular Compartments (2013)

Nanoparticle-based drug delivery systems have considerable potential for improvement of drug stability, bioavailability, and reduced dosing frequency. Important technological advantages of nanoparticles include high carrier capacity across biological membranes and controlled drug release. Ultimately, success of nanodelivery systems depends on toxicologic issues associated with the understanding of the fate of nanocarriers and their polymeric constituents within the targeted cells. Here we describe a method for determining subcellular distribution of nanoparticles by isolation and identification of organelles that come in direct contact with these structures.

Harnessing real-world depth edges with multiflash imaging (2005)

A method for capturing geometric features of real-world scenes relies on a simple capture setup modification. The system might conceivably be packaged into a portable self-contained device. The multiflash imaging method bypasses 3D geometry acquisition and directly acquires depth edges from images. In the place of expensive, elaborate equipment for geometry acquisition, we use a camera with multiple strategically positioned flashes. Instead of having to estimate the full 3D coordinates of points in the scene (using, for example, 3D cameras) and then look for depth discontinuities, our technique reduces the general 3D problem of depth edge recovery to one of 2D intensity edge detection. Our method could, in fact, help improve current 3D cameras, which tend to produce incorrect results near depth discontinuities. Exploiting the imaging geometry for rendering provides a simple and inexpensive solution for creating stylized images from real scenes. We believe that our camera will be a useful tool for professional artists and photographers, and we expect that it will also let the average user easily create stylized imagery. This article is available with a short video documentary on CD-ROM.
Mutual reference frame-quality assessment for first-person videos (2017)

First-person videos (FPVs) captured by wearable cameras are explored for applications of sharing experiences, recording daily lives, measuring social interactions and behaviors. These applications can be improved by an accurate quality assessment. To maximally use the information present in a FPV, we introduce a new strategy for image quality assessment, called mutual reference (MR). MR does not fit into the previous categorization of full-reference, reduced-reference and no-reference. It uses the overlapping content between images to provide effective information for quality estimation. We propose a framework of mutual reference frame-quality assessment for FPVs (MRFQAFPV) to implement the MR strategy based on a MR quality estimator (QE), LVI. The effectiveness of MRFQAFPV is demonstrated in a subjective test by comparing with 3 no-reference QEs and frame-to-frame motion.

A Hybrid Hierarchical Model for Multi-Document Summarization (2010)

summaries created by humans is important in extractive multi-document summarization. In this paper, we formulate extractive summarization as a two step learning problem building a generative model for pattern discovery and a regression model for inference. We calculate scores for sentences in document clusters based on their latent characteristics using a hierarchical topic model. Then, using these scores, we train a regression model based on the lexical and structural characteristics of the sentences, and use the model to score sentences of new documents to form a summary. Our system advances current state-of-the-art improving ROUGE scores by ∼7%. Generated summaries are less redundant and more coherent based upon manual quality evaluations. 1
Asymmetric Coordination Polymerization of Acrylamides by Enantiomeric Metallocenium Ester Enolate Catalysts (2007)

Analysis of the extractive and hydrolytic behavior of microthane poly(ester‐urethane) foam by high pressure liquid chromatography (1993)

Microthane foam, a poly(ester-urethane) (PU) used in the manufacture of Meme/Replicon breast implants, was analyzed by an HPLC method to determine whether 2,4- and 2,6-toluenediamine (TDA) were formed under a variety of physiological and nonphysiological extraction and hydrolytic conditions. At our detection limit of 20 ppb, no 2,4- or 2,6-TDA was observed in either methyl tert-butyl ether (MTBE), or aqueous buffer extracts of PU foam. The predominant extractable components identified by HPLC UV-analysis, were mixture of nonaromatic and aromatic PU fragments. Moreover, no detectable amounts of TDA were found in foam or MTBE extract of foam incubated in phosphate buffer, pH 7.4, at 37 degrees C for 5 days. By contrast, 2,4- and 2,6-TDA were found in foam and foam extracts exposed to low concentrations of either strong mineral acid or base; higher levels were found at higher acidity, treatment temperature, or durations of incubation. Moreover, 2,4- and 2,6-TDA were found in oligomers isolated by preparative HPLC and exposed to alkaline conditions. Finally, 1-2 ppm of 2,4-TDA was detected when PU foam extracts were prepared by the Snyder-Breder method, which employs acidic and alkaline conditions in the work-up procedure. Based on these findings, we suggest that published observations of 2,4-TDA formation from in vitro and ex vivo extractions of PU foam are artifacts resulting from pH effects on oligomeric PU fragments present in or extracted from the foam.
Diversity in wireless systems (2001)

The main impairment in wireless channels is fading or random fluctuation of the signal level. This signal fluctuation happens across time, frequency, and space. Diversity techniques provide the receiver with multiple independent looks at the signal to improve reception. Each one of those independent looks is considered a diversity branch. The probability that all diversity branches will fade at the same time goes down as the number of branches increases. Hence, with a high probability, there will be at least one branch or link with a good signal such that the transmitted data can be detected reliably.
On the optimum separation distance for minimum noise of contra-rotating propellers (2020)

Overlapping propeller systems are currently used on some urban flight vehicles and will become increasingly common in future electric propulsion, since they provide one of the most compact platform volumes per thrust. This paper presents the results of a detailed experimental investigation of co-axial contra-rotating propeller configuration at hover condition. A detailed parametric study is performed to investigate the sensitivity of radiated noise to axial separation distance. An optimum separation distance z to propeller diameter D of 0.25 has been identified, whereby minimum radiated noise is obtained. The reason for this optimum has been explored and the balance between various interaction noise sources in co-axial configuration is discussed in the paper. It is also shown that the minimum radiated noise was roughly found where the aerodynamic efficiency is maximum.
Electron beam remediation of soils impacted with heavy hydrocarbons (2023)

During electron beam (EBeam) irradiation, high-energy electrons can generate physical and chemical changes in a substance such as chain scission and cross-linking. Irradiation of soil is shown to be an effective technology for rapid reduction of Total Petroleum Hydrocarbons (TPH) in crude oil impacted soils. An experimental apparatus for batch treatment of 100 g soil samples was built and tested using a 10 MeV, 15 kW electron beam. The samples were a variety of crude oil impacted soil samples with TPH contents ranging between 1.6 and 32% by mass. Soils of initial TPH up to 9.1% (dry weight basis) TPH levels were reduced to below a target cleanup level of 1% with irradiation doses ranging from 700 kJ/kg to 1100 kJ/kg and treatment times less than 200 seconds, with maximum soil temperatures less than 450°C. Soils with elevated moisture content required higher dosages or preliminary drying. EBeam treatments resulted in 1) reduction for both light and heavy hydrocarbon, 2) generation of new light hydrocarbons, and 3) generation of fixed carbon, indicating that the mechanisms of electron beam remediation include radical induced reactions at relatively low temperature and relatively short time scales and not simply thermal desorption effects.
Mechanism to induce geometric constriction on kinks and domain walls (2023)

Abstract We investigate scalar field theories in the multifield scenario, focusing mainly on the possibility to smoothly build internal structure and asymmetry for kinks and domain walls. The procedure requires the inclusion of an extra field which is associated to a function that modifies the dynamics of the other fields. We investigate minimum energy configurations, which support first order equations compatible with the equations of motion. The extra field allows a transition which is guided by a parameter that connects the standard solution to another one, geometrically constrained, mimicking the effects of geometrical constrictions in magnetic materials.
EU FP7 INFSO-ICT-247223 ARTIST4G, D1.1 Definitions and architecture requirements for supporting interference avoidance techniques (2010)

It is the main objective of the ARTIST4G Work Package 1 (WP1), to design innovative interference avoidance solutions by means of transmitter signal processing, scheduling and/or cross layer techniques. Such an approach will enable to identify optimal strategies also taking into account the practical implications on the real system. The major impacts of the WP1 innovations on the radio access network and on the mobile system interfaces, together with constraints due to practical implementations, will be analyzed in this deliverable. This deliverable will be a reference for the work in ARTIST4G Work Package 4 (WP4).A set of guiding questions used to precise the requirements for WP4 has been considered for each new cooperation/coordination functionality. Answers to these questions are provided in this deliverable by grouping the different classes of WP1 innovations into 4 categories with similar requirements on the radio access architecture. For each question, current, expected, minimum and maximum targets of the requirement will be given, helping to ensure that the range of all possible values for all the innovations are taken into account.
TIME CHANGES OF CONTRAST THRESHOLDS DURING AUTOMATIC PERIMETRY (1977)

Contrast thresholds were continuously recorded in six points of the visual field through a repetitive up-and-down staircase method using the automatic perimeter developed by Heijl & Krakau (1975b). The uninterrupted sessions lasted about 30 min. Nineteen patients with a verified diagnosis of glaucoma, or in whom glaucoma was suspected, and twelve healthy normal subjects were tested. With increasing test time, a decreased contrast sensitivity was found. In most subjects the mean threshold increment was small (less than 1.5 dB). The threshold increments were larger in the patient group than in the normal subjects--many test points showing increments of 6-10 dB during the test session. Such a large deterioration of sensitivity was most common in eyes with visual field defects. Test points which showed large threshold increments were often situated in the vicinity of documented visual field defects. In eyes with pathological visual fields, the short-term variation increased with increasing test time. An impairment of fixation with increasing test time was found in the patient group.
CGRP stimulates the release of pro-somatostatin-derived peptides from the gastric fundus (1990)

Calcitonin gene-related peptide (CGRP) stimulates release of peptides derived from pro-somatostatin (Pro-S) into the general circulation. The purpose of this investigation was to elucidate the origin and molecular heterogeneity of Pro-S-derived peptides secreted in response to CGRP. Catheters were placed into the vena cava and veins draining the gastric fundus and corpus, antrum, and small intestine of anesthetized pigs. Human CGRP I was infused into the descending aorta at 0.2, 0.4, 0.8, and 1.6 micrograms.kg-1.h-1 for consecutive 30-min intervals. Blood was collected from the venous catheters after each period. S-28 was separated from Pro-S, S-14, and S-13 by immunoaffinity chromatography and peptides were quantified by radioimmunoassay. CGRP primarily evoked release of peptides measured collectively as Pro-S, S-14, and S-13 into venous blood draining the fundus and corpus, and concentrations were significantly elevated above basal at 0.8 and 1.6 micrograms.kg-1.h-1 CGRP (P less than 0.05). Basal concentrations of S-28, Pro-S, S-14, and S-13 in blood from the antrum and small intestine were not significantly elevated by CGRP. In conclusion, CGRP stimulated release of Pro-S-derived peptides from the gastric fundus and corpus but not from the antrum or small intestine.

An equivalent lumped circuit describing an FDTD cell filled with plasma is developed and applied in the analysis. Such a method is proved more effective than previously reported methods. The new approach is verified on a canonical example of known analytical solution.
