Effects of the Impeller Blade with a Slot Structure on the Centrifugal Pump Performance (2020)

An impeller blade with a slot structure can affect the velocity distribution in the impeller flow passage of the centrifugal pump, thus affecting the pump’s performance. Various slot structure geometric parameter combinations were tested in this study to explore this relationship: slot position p, slot width b1, slot deflection angle β, and slot depth h with (3–4) levels were selected for each factor on an L16 orthogonal test table. The results show that b1 and h are the major factors influencing pump performance under low and rated flow conditions, while p is the major influencing factor under the large flow condition. The slot structure close to the front edge of the impeller blade can change the low-pressure region of the suction inlet of the impeller flow passage, thus improving the fluid velocity distribution in the impeller. Optimal slot parameter combinations according to the actual machining precision may include a small slot width b1, slot depth h of ¼ b, slot deflection angle β of 45°–60°, and slot position p close to the front edge of the blade at 20–40%.
MOBICORS-Movie: A MOBIle COntents Recommender System for Movie (2004)

The owners of 135 pet birds were surveyed by questionnaire to determine their birds' weekly food consumption. The birds were divided into six food groups on the basis of the amounts of seeds, formulated products and human food they consumed. The formulated products and seeds were analysed for their nutrient content by two independent laboratories, the nutrient content of the human foods was obtained from a standard nutrition reference, and each bird's nutrient intake was estimated. The dietary content of individual nutrients was then compared with the estimated maintenance requirements for pet birds. Birds consuming less than approximately 50 per cent of their diets as formulated products had inadequate intakes of vitamins A and D3, and calcium. Diets high in human food were low in protein, energy, vitamins and minerals. Diets high in seed were excessive in fat and deficient in vitamins A and D3, and calcium.

Diodes Schottky et MIS tunnel sur silicium amorphe hydrogéné de qualité photovoltaïque préparé par pulvérisation cathodique Caractérisation électrique par mesures capacitives (1979)

Des diodes Schottky et MIS tunnel (Métal-Isolant-Semiconducteur) ont été réalisées sur silicium amorphe hydrogéné obtenu par pulvérisation cathodique. Le matériau présente une forte photoconductivité ; la tension de circuit ouvert et le courant de court-circuit de la diode Schottky sont respectivement 700 mV et 4 mA/cm2 sous éclairement AM1 en l'absence de couche anti-réfléchissante. Les dispositifs sont utilisés pour la caractérisation électrique du matériau : on relève les caractéristiques courant-tension en fonction de la température et capacité-tension en fonction de la fréquence. On donne une estimation de la distribution des états électroniques dans la bande d'énergie interdite du matériau ; les résultats indiquent une très faible densité d'états autour du milieu de la bande interdite (< 1016 cm-3 eV -1). Les auteurs mettent en relief les principaux aspects et les difficultés des mesures de capacité de diodes Schottky préparées sur silicium amorphe hydrogéné.

Automated High-Speed Analysis of Holter Tapes with Microcomputers (1983)

We have developed an automated Holtes scanning system based on two microcomputers. One is a preprocessor that detects QRS complexes and measures the QRS durations using computations of first and second derivatives. Thismicrocomputer interfaces to a secondmicro-computer that does arrhythmia analysis, logging, and reporting using R-R intervals and QRS durations. This system can process Holter tapes at 60 times real time and produce printed summaries and 24 h trend plots of several variables including heart rate and PVC count.
The signal dimensions in multiple-antenna channels (2004)

This paper develops a physical channel model for multiple-antenna systems. The model appropriately abstracts the scattering intensity of physical environments, geometry of antenna arrays and degrees of polarization. Then, we use the model to demonstrate that the "space" in wireless systems is composed of three signal dimensions: wavevector, array and polarization. The impact of physical environment, array geometry and polarization are captured separately in the wavevector, array and polarization dimensions respectively. Thus, we solidify the "space" dimensions in complement to the time and frequency dimensions, and unify the available signal space in wireless channels.

The procedures reported accommodate three points of diversification around this bisheterocyclic scaffold and the resulting library of compounds has been added to the National Institutes of Health repository (ca. 10 mg of each with >90% purity) for pilot-scale biomedical studies with bioassay data available at the National Center for Biotechnology Information PubChem database.
Efficiently monitoring bandwidth and latency in IP networks (2002)

Effective monitoring of network utilization and performance indicators is a key enabling technology for proactive and reactive resource management, flexible accounting, and intelligent planning in next-generation IP networks. In this paper, we address the challenging problem of efficiently monitoring bandwidth utilization and path latencies in an IP data network. Unlike earlier approaches, our measurement architecture assumes a single point-of-control in the network (corresponding to the network operations center) that is responsible for gathering bandwidth and latency information using widely-deployed management tools, like SNMP, RMON/NetFlow, and explicitly-routed IP probe packets. Our goal is to identify effective techniques for monitoring (a) bandwidth usage for a given set of links or packet flows, and (b) path latencies for a given set of paths, while minimizing the overhead imposed by the management tools on the underlying production network. We demonstrate that minimizing overheads under our measurement model gives rise to new combinatorial optimization problems, most of which prove to be NP-hard. We also propose novel approximation algorithms for these optimization problems and prove guaranteed upper bounds on their worst-case performance. Our simulation results validate our approach, demonstrating the effectiveness of our novel monitoring algorithms over a wide range of network topologies.
Optomechanical Quantum Information Processing with Photons and Phonons (2012)

We describe how strong resonant interactions in multimode optomechanical systems can be used to induce controlled nonlinear couplings between single photons and phonons. Combined with linear mapping schemes between photons and phonons, these techniques provide a universal building block for various classical and quantum information processing applications. Our approach is especially suited for nano-optomechanical devices, where strong optomechanical interactions on a single photon level are within experimental reach.
Inhibition of acetate accumulation leads to enhanced production of (<i>R,R</i>)-2,3-butanediol from glycerol in<i>Escherichia coli</i> (2012)

This work describes the production of (R,R)-2,3-butanediol in Escherichia coli using glycerol by metabolic engineering approaches. The introduction of a synthetic pathway converting pyruvate to (R,R)-2,3-butanediol into wild-type E. coli strain BW25113 led to the production of (R,R)-2,3-butanediol at a titer of 3.54 g/l and a yield of 0.131 g product/g glycerol (26.7 % of theoretical maximum) with acetate (around 3.00 g/l) as the dominant by-product. We therefore evaluated the impacts of deleting the genes ackA or/and poxB that are responsible for the major by-product, acetate. This increased production of (R,R)-2,3-butanediol to 9.54 g/l with a yield of 0.333 g product/g glycerol (68.0 % of theoretical maximum) in shake flask studies. The utilization of low-priced crude glycerol to produce value-added chemicals is of great significance to the economic viability of the biodiesel industry.
The Elimination of Marital Fault in Awarding Spousal Support: The Minnesota Experience (2001)

The focus of this article is to examine the historical development and current status of one particular economic issue associated with the dissolution of a marriage: the award of spousal support. A court is called upon to consider not only whether an award of spousal support is appropriate but, if so, the amount and duration of the support as well. A comparison of approach to spousal support in Minnesota with other states highlights the underlying debate on these important issues of public policy.

Two Trillion and Counting (1994)

Most of what can be said about the rapid growth of mutual funds has been said. Total assets of all mutual funds have passed the $2 trillion mark and, barring a turnaround on Wall Street, could match or even exceed total commercial bank deposits by the end of 1994. Banks are playing a part in this remarkable market phenomenon. Some 3,500 banks sell mutual funds, and it's been estimated that 15-20% of sales today are handled through The growing involvement of banks in this market shouldn't surprise anyone. Low interest rates are driving bank customers to seek higher returns than those offered by CDs, and it's logical that banks would offer these products to keep their customers at the bank. The advantages of convenience, investment advice, and performance further help to make bank mutual funds a very attractive investment alternative. Naturally, our growing role in mutual funds has attracted attention from Washington. But even without that added scrutiny, it's incumbent for us as bankers to ask ourselves: How much do our mutual-fund customers really know about the uninsured investments they are making through our banks? How confident can we be, for example, that every one of our mutual-fund customers understands that these investments are not FDIC-insured? How of our customers understand that mutual funds are not an obligation of, or guaranteed by, the bank? And how know that the funds involve investment risk, including the possible loss of principal? When the stock market corrects, will our customers be sophisticated enough to understand that the value of mutual-fund investments rises and falls with the market? Or will they line up at the front door with tar and feathers in hand? A survey by the Securities and Exchange Commission in November found that one-in-five holders of mutual funds believe that funds sold through banks are federally insured. The SEC also found that two-in-five holders of mutual funds (39%) believe mutual funds purchased from a stockholder are federally insured. Obviously, some people are confused. At ABA's annual convention in San Diego, the Comptroller of the Currency Eugene Ludwig, warned that many consumers still do not understand that they can lose money on mutual funds that they buy from commercial banks. I believe we can make full voluntary consumer disclosure a win-win situation for our customers and the industry. …
Design Tables for an Elliptic-Function Band-Stop Filter (N=5) (1966)

Design tables for a wide-band elliptic-function band-stop trammission-line filter are described. The filter consists of five alternating quarter-wave and half-wave stubs separated by quarter-wave lines. The characteristic impedances of the filter elements were computed from published tables of the lumped-element prototype by an exact method. The filter elements are assumed to be lossless.
Primary Amebic Meningoencephalitis Caused by<i>Naegleria fowleri</i>, Karachi, Pakistan (2011)

We report 13 cases of Naegleria fowleri primary amebic meningoencephalitis in persons in Karachi, Pakistan, who had no history of aquatic activities. Infection likely occurred through ablution with tap water. An increase in primary amebic meningoencephalitis cases may be attributed to rising temperatures, reduced levels of chlorine in potable water, or deteriorating water distribution systems.
Diffuse optical measurement of blood flow in breast tumors (2005)

Blood flow contrast between tumor and normal tissues in patients with malignant and benign breast cancer was measured by diffuse optical correlation methods. The measurements were carried out with a hand-held optical probe that was manually scanned over the tumor-bearing breast. Increased blood flow was observed in tumor regions relative to healthy tissue, and control subjects did not exhibit significant blood flow heterogeneity. The measurements introduce a new optical contrast for diffuse optical mammography.
Harmonics mitigation using active power filter: a technological review (2006)

Abstract: This paper is intended to review the development of active power filter (APF) technologies that are commonly used to mitigate harmonics in utility power lines. This review can also be considered as a “tutorial-type paper ” as it provides a holistic coverage of the APF technologies by omitting the tedious details, but without losing the main essence of the subject matter. It is hoped that by this approach, it would be possible to lure more power engineering readers to be involved in this important and growing field. The discussion starts with a brief overview of harmonic distortion problems and their impacts on electric power quality. The operation of common APF topologies, namely the shunt, series and hybrid APFs are described in detail. This is followed by a review on different types of reference signal estimation extraction techniques. In particular, the application of the p-q and extension p-q theorems to extract the reference signals are elaborated, as they are the most commonly found in practical APF systems. Finally, an overview of the APF control strategies is provided. A brief discussion on the APF-solar photovoltaic system is also given. At the end of the paper, important references are cited to assist readers who are interested to explore the subject in greater detail.
Fabrication and Characterization of the ${\rm MgB}_{2}$ Bulk Superconductors Doped by Carbon Nanotubes (2009)

Carbon nanotube (CNT) doped MgB <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1.9</sub> - 0.1 at% CNT bulk superconductors were fabricated using an in-situ technique to improve the critical current density (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> ) in a high magnetic field. The effects of doping and the sintering temperature on the phase formation, microstructure, and critical properties were evaluated. Two types of the CNT were used as dopants: the conventional CNT (C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CNT</sub> ) with a mixture of large and small diameter (5 and 20 nm) and the small CNT (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CNT</sub> ) with 5 nm diameters. For both CNT-doped samples, the a-axis lattice parameter decreased but its reduction was more significant at 900degC than at 800degC. The decrease in T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> was consistent with the change in the a-axis lattice parameter, which is probably due to the effect of C substitution for the B sites in MgB <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . The J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> of the doped samples decreased more slowly with increasing magnetic field than that of the undoped samples. In addition, the S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CNT</sub> -doped sample exhibited superior J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> (B) behavior than the C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CNT</sub> -doped sample. This was partly attributed to the higher doping level and the presence of finer CNTs, which acts as an effective pinning center.

An attempt has been made in this article to cover all the aspects of air abrasion and to remove the misconceptions present about this technique.
Mutational Analysis of a Conserved Signal-Transducing Element: the HAMP Linker of the<i>Escherichia coli</i>Nitrate Sensor NarX (2002)

The HAMP linker, a predicted structural element observed in sensor proteins from all domains of life, is proposed to transmit signals between extracellular sensory input domains and cytoplasmic output domains. HAMP (histidine kinase, adenylyl cyclase, methyl-accepting chemotaxis protein, and phosphatase) linkers are located just inside the cytoplasmic membrane and are projected to form two short amphipathic alpha-helices (AS-1 and AS-2) joined by an unstructured connector. The presumed helices are comprised of hydrophobic residues in heptad repeats, with only three positions exhibiting strong conservation. We generated missense mutations at these three positions and throughout the HAMP linker in the Escherichia coli nitrate sensor kinase NarX and screened the resulting mutants for defective responses to nitrate. Most missense mutations in this region resulted in a constitutive phenotype mimicking the ligand-bound state, and only one residue (a conserved Glu before AS-2) was essential for HAMP linker function. We also scanned the narX HAMP linker with an overlapping set of seven-residue deletions. Deletions in AS-1 and the connector resulted in constitutive phenotypes. Two deletions in AS-2 resulted in a novel reversed response phenotype in which the response to ligand was the opposite of that seen for the narX(+) strain. These observations are consistent with the proposed HAMP linker structure, show that the HAMP linker plays an active role in transmembrane signal transduction, and indicate that the two amphipathic alpha-helices have different roles in signal transduction.
Voltammetric Detection for Capillary Electrophoresis (1997)

Several approaches to implementing amperometric detection for capillary electrophoresis have been reported. This report describes the development of a voltammetric detector for CE. The detector is designed to minimize distortion of the voltammetry due to ohmic potential drop. This was accomplished by using a cast Nafion detection cell at the end of the separation capillary. The cast Nafion detection cell provided a low-dead-volume, low-resistance cell that minimized ohmic potential drop and peak band broadening. The ability to detect the current due to oxidation of analytes superimposed on a large background current was also improved. A dynamic background subtraction scheme was used in which a second working electrode, positioned in the electrochemical cell but outside of the detection cell, was used to compensate for the background current in real time. The output of the compensating working electrode was subtracted from the output of the detecting working electrode prior to analog-to-digital conversion. Postexperimental digital background subtraction was also implemented. This approach provided optimal elimination of the background current with maximal detection of the analytical signal. The voltammetric detector developed produced high-quality voltammetric response of analytes with injected concentrations as low as 0.20 microM. The system was evaluated by obtaining CE voltammograms of a mixture of eight test phenolic acids.
Certain confusion over uncertainty (2002)

Automatic run-time extraction of communication graphs from multithreaded applications (2006)

Embedded system synthesis, multiprocessor synthesis, and thread assignment policy design all require detailed knowledge of the runtime communication patterns among different threads or processes. Researchers have commonly relied on manual estimation, compiletime analysis, or synthetic benchmarks when developing and evaluating synthesis algorithms and thread assignment policies. In a more ideal world, it would be possible to quickly and easily determine the run-time communication properties of large commercial and academic multithreaded applications. This article describes a fully-automated method of extracting run-time communication graphs from multithreaded applications. The resulting graphs may be used to better understand, design, and synthesize application-specific hardware-software systems. The proposed graph extraction method is implemented as a module within the Simics multiprocessor simulator. It presently supports the analysis of arbitrary multithreaded applications running on the Linux operating system. This software is called CETA. It is freely available for academic and non-profit use.
Probabilistic Image Colorization (2017)

We develop a probabilistic technique for colorizing grayscale natural images. In light of the intrinsic uncertainty of this task, the proposed probabilistic framework has numerous desirable properties. In particular, our model is able to produce multiple plausible and vivid colorizations for a given grayscale image and is one of the first colorization models to provide a proper stochastic sampling scheme. Moreover, our training procedure is supported by a rigorous theoretical framework that does not require any ad hoc heuristics and allows for efficient modeling and learning of the joint pixel color distribution. We demonstrate strong quantitative and qualitative experimental results on the CIFAR-10 dataset and the challenging ILSVRC 2012 dataset.
Transplantation of cultured human neonatal corneal endothelium (1986)

Human neonatal corneal endothelial cells were successfully maintained in tissue culture, morphologically resembling adult corneal endothelium. Eyebank donor corneas were obtained, denuded of their native endothelium and seeded with a suspension of the cultivated neonatal endothelial cells. After 48 hours, the eye-bank tissue was then transplanted into the eyes of Rhesus monkeys. Over a five month period, five of eight transplants cleared, with a mean central corneal thickness of 0.480 mm and endothelial cell densities ranging from 560 to 1650 cells/mm2. All control eyes without donor endothelium remained cloudy. In the experimental group three eyes initially thinned but subsequently became edematous. Further studies are needed to improve the seeding procedure and to assess the long-term viability of transplanted endothelium.
