Libra: An Economy driven Job Scheduling System for Clusters (2002)

Clusters of computers have emerged as mainstream parallel and distributed platforms for high-performance, high-throughput and high-availability computing. To enable effective resource management on clusters, numerous cluster managements systems and schedulers have been designed. However, their focus has essentially been on maximizing CPU performance, but not on improving the value of utility delivered to the user and quality of services. This paper presents a new computational economy driven scheduling system called Libra, which has been designed to support allocation of resources based on the users? quality of service (QoS) requirements. It is intended to work as an add-on to the existing queuing and resource management system. The first version has been implemented as a plugin scheduler to the PBS (Portable Batch System) system. The scheduler offers market-based economy driven service for managing batch jobs on clusters by scheduling CPU time according to user utility as determined by their budget and deadline rather than system performance considerations. The Libra scheduler ensures that both these constraints are met within an O(n) run-time. The Libra scheduler has been simulated using the GridSim toolkit to carry out a detailed performance analysis. Results show that the deadline and budget based proportional resource allocation strategy improves the utility of the system and user satisfaction as compared to system-centric scheduling strategies.
Bezoars: a special cause of ileal obstruction in mentally retarded patients. (1991)

Abdominal symptoms in mentally retarded patients may pose difficult diagnostic problems due to an unreliable history of disease and incooperation of the patients. The case histories are presented of three patients with bezoars in the ileum. Delayed diagnosis and signs of peritonitis necessitated emergency surgery. All patients could successfully be treated by small bowel resection and primary anastomosis. In mentally retarded patients with abdominal pain a bezoar must be considered.
Advanced single-rotation propfan drive system (1985)

E CONOMIC and strategic incentives to reduce aircraft fuel consumption have prompted significant government and industry interest in advanced turboprop aircraft for the 1990s. Scale-model wind tunnel testing has shown that large improvements in propulsive efficiency are achievable with a propfan at the high-speed flight conditions of advanced turbofan-powered aircraft. The propfan design concept shown in Fig. 1 is a full-size system for test evaluation in NASA's Propfan Test Assessment (PTA) flight research program in mid-1987. The work described herein is the single-rotation gearbox phase of Allison's Advanced Propfan Engine Technology (APET) study sponsored by the NASA Lewis Advanced Turboprop Office. Today, with the propfan approach of thin-swept highly loaded blades, the flight envelope for commercial turboprop aircraft can be extended in speed and altitude to include the turbofan cruise points. The APET study established the engine cycle trades for an extended turboprop flight envelope. Cost/benefit analyses based on the specific fuel consumption advantages of a high-pressure-ratio cycle showed the advantage of operating in the 30:1 to 40:1 range, which is compatible with 1990's component technology. Turbine inlet temperatures on the order of 2500°F would complement the high pressure and, at the same time, not compromise hotsection life. The APET study also showed that the advanced turboprop propulsion system should be designed using modular concepts to enhance maintenance of components and auxiliary systems. The following discussion describes the preliminary design of a single-rotation (SR) propfan gearbox.
Role of Extra‐Esophageal Reflux in Chronic Otitis Media with Effusion (2007)

Pepsin was detected in 60% of patients with OME, confirming that EER into the middle ear occurs in these children. The pepsin present would have little or no activity at pH 6.0 to 7.6; however, pepsin is stable below pH 8.0 and thus could be reactivated after a decrease in pH.
Measurement of theBs0Lifetime in the Exclusive Decay ChannelBs0→J/ψϕ (2005)

Using the exclusive decay B0s-->J/psi(mu+mu-)phi(K+K-), we report the most precise single measurement of the B0s lifetime. The data sample corresponds to an integrated luminosity of approximately 220 pb(-1) collected with the D0 detector at the Fermilab Tevatron Collider in 2002-2004. We reconstruct 337 signal candidates, from which we extract the B0s lifetime, tau(B0s)=1.444(+0.098)(-0.090)(stat)+/-0.020(sys) ps. We also report a measurement for the lifetime of the B0 meson using the exclusive decay B0-->J/psi(mu+mu-)K*0(892)(K+pi-). We reconstruct 1370 signal candidates, obtaining tau(B0)=1.473(+0.052)(-0.050)(stat)+/-0.023(sys) ps, and the ratio of lifetimes, tau(B0s)/tau(B0)=0.980(+0.076)(-0.071)(stat)+/-0.003(sys).

Biochemical characterisation of flagellates isolated from fruits and seeds from Brazil (1999)

Seven flagellates of the family Trypanosomatidae have been isolated from different fruits and seeds from Brazil, three from tomato fruit (Lycopersicum esculentum), one from urucum fruit (Bixa orellana), two from maize kernels (Zea mays) and one from bean (Phaseolus vulgaris). These isolates were characterised by isoenzymatic analysis, using nine enzymatic systems and the isoenzymatic profiles were compared with those obtained from different flagellates already described as belonging to the genera Phytomonas, Herpetomonas and Crithidia. Most of the isoenzymes were able to distinguish the new plant isolates from insect trypanosomatids (Herpetomonas and Crithidia). Six of the isolates could be ascribed to the genus Phytomonas, five of them being phylogenetically closely related to Phytomonas serpens. The new isolates excreted the same metabolic end-products into the external medium and only small quantitative differences were found among the different isolates.
Transcriptional data: a new gateway to drug repositioning? (2012)

Recent advances in computational biology suggest that any perturbation to the transcriptional programme of the cell can be summarised by a proper 'signature': a set of genes combined with a pattern of expression. Therefore, it should be possible to generate proxies of clinicopathological phenotypes and drug effects through signatures acquired via DNA microarray technology. Gene expression signatures have recently been assembled and compared through genome-wide metrics, unveiling unexpected drug-disease and drug-drug 'connections' by matching corresponding signatures. Consequently, novel applications for existing drugs have been predicted and experimentally validated. Here, we describe related methods, case studies and resources while discussing challenges and benefits of exploiting existing repositories of microarray data that could serve as a search space for systematic drug repositioning.
Coffee Drinking Influences Plasma Antioxidant Capacity in Humans (2002)

Coffee and tea are widely consumed beverages, but only tea has been studied for its antioxidant capacity (AC) in vivo. The aim of this study was to compare the capacities of coffee and tea to affect plasma redox homeostasis in humans. The AC of plasma before and after supplementation with 200 mL of beverages (0, 1, and 2 h) was measured by the TRAP and crocin tests. The crocin test detected an increase in plasma AC only in subjects supplemented with coffee (+7% at peak time), whereas the TRAP method showed an increase in plasma AC after consumption of both coffee and tea (+6 and +4%, respectively, at peak time). Both beverages induced a significant increase in plasma uric acid (+5 and +7%, respectively). Uric acid strongly affects the results obtained by the TRAP test and does not affect those obtained by the crocin test. We can thus argue that uric acid is the main component responsible for the plasma AC increase after tea drinking, whereas molecules other than uric acid (probably phenolic compounds) are likely to be responsible for the increase in plasma AC after coffee drinking.
Stimulated emission depletion microscopy with an offset depleting beam (2001)

We demonstrate that an offset stimulated emission depletion (STED) beam breaks the diffraction barrier of fluorescence microscopy in both the lateral and the axial directions. A 2.5-fold axial reduction of the focal spot is accomplished through the ear-shaped lobes of the diffraction maximum of the STED beam. The effect of the minima and side maxima of the STED beam on the lateral and axial resolution is shown to be in remarkable agreement with theory. Conditions are given for which a regular STED beam reduces the axial extent of a confocal spot from 490±36 to 175±18 nm, and simultaneously from 183±12 to 70±8 nm along the direction of the offset. The latter establishes the lowest reported value in far-field fluorescence microscopy.
Mechanical criterion for nucleation of intergranular stress corrosion cracking in austenitic stainless steel (2021)

This study investigated mechanical criteria for the nucleation of intergranular stress corrosion cracking (IGSCC) in thermally-sensitized type 304 austenitic stainless steel. Constant load testing was conducted on a stainless-steel specimen in a tetrathionate solution, and the cracking behavior, including crack initiation, coalescence, and growth at grain boundaries (GBs) on the specimen surface, was observed in situ. Local normal strains along GBs were measured on the smooth surface via the digital image correlation (DIC) technique. Local normal stresses at GBs were estimated using the Schmid-modified grain boundary stress (SMGBS) model, which has been widely used for evaluating the stress state of GBs, considering the effect of the GB plane geometry and grain orientations of grains adjacent to the GBs. The relationship between IGSCC nucleation sites, strains, and stresses was discussed. As a result, there was a slight correlation between local normal stress obtained via the SMGBS model and local normal strain via DIC measurement. The use of experimentally measured local normal strain was found to be suitable to characterize IGSCC nucleation sites.
Text to Hypertext Conversion with L A T E X2HTML (1994)

Comparison of the Vibrio cholerae hemagglutinin/protease and the Pseudomonas aeruginosa elastase (1990)

The soluble hemagglutinin/protease (HA/protease) produced by Vibrio cholerae and the elastase of Pseudomonas aeruginosa are both zinc/calcium-dependent proteases. In the present study the two enzymes are compared immunologically and functionally. The N-terminal amino acid sequences of the proteins had 65% identity within the first 20 amino acids. Polyclonal antisera against each purified protein recognized the enzyme of the other species in enzyme-linked immunosorbent assay, checkerboard immunoblot, and Western blot analyses and inhibited the protease activity of both enzymes in milk and elastin agars. Like the HA/protease, the elastase hemagglutinated "responder" but not "nonresponder" chicken erythrocytes, degraded ovomucin, lactoferrin, and fibronectin, and nicked the A subunit of the cholera toxin-related heat-labile enterotoxin from Escherichia coli. Whereas none of the three proteases tested (elastase, HA/protease, or pronase E) had any obvious effect in ileal loop tests in rabbits at doses up to 50 micrograms, all three produced some detectable skin reactions at a dose of 0.1 micrograms and necrosis at a higher dose (i.e., 5 micrograms). We conclude that the V. cholerae HA/protease and the P. aeruginosa elastase are structurally, functionally, and immunologically related.
Stress Corrosion Susceptibility of Stress-Coined Fastener Holes in Aircraft Structures (1975)

The cold working process of stress coining is used to provide fatigue improvement of fastener holes in aircraft structures. The cold working produces a radial flow of the metal. The residual stresses resulting from stress coining provide protection against fatigue damage by opposing the applied tensile stresses in service at the edge of the fastener hole. However, it is shown in this paper that in addition to the compressive stresses surrounding the stress coined hole, there are tensile stresses that result from the coining operation and that these residual tensile stresses can have a deleterious effect on the stress corrosion susceptibility of the postcoined structure.
How Should the European Union Decentralize Its Competition Policy (2007)

This article focuses on decentralized implementation of European Union competition policy. Delegating the control of 
interfirm agreements makes it possible to benefit from better local information. However, because of conflicts of interest, 
decisions taken may not be in line with overall economic welfare. We show that this problem can be alleviated when the 
central authority delegates auditing but retains decision-making control. However, the central authority must make 
concessions: it must sometimes follow the national authorityas recommendations in order to give the latter adequate 
incentives to collect information.

Differential activation and block of peripheral nerve fibers by magnetic fields (2006)

Abstract The ability to noninvasively and reversibly block conduction in peripheral nerves would have several clinical applications. As an initial step in this direction, we investigated the possibility of magnetically generating and differentially blocking activity in mammalian peripheral nerve fibers in vitro. Compound action potentials at each end of individual explanted phrenic nerves were recorded in response to currents induced at the midpoint of the nerve with an externally placed magnetic coil. Current in the coil was then reversed and the recordings repeated. In all cases, the area under the compound action potential on the virtual anode side of the magnetic stimulus was reduced (mean of 18.2 ± 8.8%) in comparison to the area on the virtual cathode side. This indicates that peripheral nerve activity can be differentially induced by magnetic stimulation. Extension of this effect to the point of generating unidirectional action potentials in vivo may prove clinically useful in a number of contexts, such as reducing contractures secondary to spasticity and generating magnetically induced anesthesia in limbs. Further investigations of this effect seem warranted. Muscle Nerve, 2006
Dielectric properties of amorphous hydrogenated silicon carbide thin films grown by plasma-enhanced chemical vapor deposition (2003)

The dielectric properties have been determined for stoichiometric amorphous hydrogenated silicon carbide (a-SiC:H) films grown by means of the plasma-enhanced chemical vapor deposition (PECVD) technique. The dielectric constant, dielectric loss, breakdown voltage, and current–voltage (I–V) characteristics of the a-SiC:H PECVD films were systematically determined for various film thicknesses in the 90–1400 nm range. The PECVD a-SiC:H films exhibit not only a dielectric constant as high as 14 but also relatively high breakdown field values around 3 MV/cm. The dielectric constant of the a-SiC:H films was found to remain almost constant over all the investigated frequency range of 1 kHz to 13 MHz, while it decreases as the film thickness is diminished. The analysis of the I–V characteristics of the a-SiC:H films has revealed the existence of two different conduction mechanisms depending on the applied voltages. While exhibiting an ohmic conduction in the low-field region (&amp;lt;0.05 MV/cm), the film conduction at high fields (&amp;gt;0.25 MV/cm) is dominated by the Poole–Frenkel effect. In the low-field region, the conductivity of the a-SiC:H films was found to decrease exponentially from 10−10 S/cm to about 10−12 S/cm as the film thickness is increased from 90 to 1400 nm. At high fields, a thermal breakdown of the a-SiC:H films occurred at about 3 MV/cm as a consequence of thermal instabilities induced by Joule heating. The excellent dielectric properties of the PECVD a-SiC:H films are seen to be a consequence of their high density and low defect concentration.
A nude mouse xenograft model of fetal intestine development and differentiation (1992)

This report describes a novel in vivo model of intestinal differentiation. Fourteen day, undifferentiated fetal rat small intestine, stripped of the major part of its mesenchyme, suspended in a type I collagen gel and then xenografted into a nude mouse, undergoes small intestinal morphogenesis and cytodifferentiation. All four major epithelial lineages, namely Paneth, goblet, columnar and endocrine are present. Double-label nonisotopic in situ hybridization, employing biotinylated and digoxigenin-labelled whole rat DNA and whole mouse DNA probes, was performed to distinguish donor cells from host cell types. The outer longitudinal smooth muscle layer, and the major part of the lamina propria, including pericryptal fibroblasts, are of host mouse origin; the inner circular smooth muscle layer is of donor rat origin. Cells of the muscularis propria and lamina propria acquired smooth muscle alpha-actin, presumably under the influence of the donor endoderm. Furthermore, this xenograft develops a host vascular network, and cells with the morphological appearance of lymphocytes are present within the intestinal epithelium. The production of chemotactic factors by the endoderm is postulated because grafting of collagen gel alone results in a minimal invasion by stromal cells which do not express smooth muscle alpha-actin.
Rhamnolipid Adsorption in Soil: Factors, Unique Features, and Considerations for Use as Green Antizoosporic Agents (2016)

In aqueous solutions, rhamnolipids effectively kill the motile zoospores responsible for spreading many pathogens, including soy-infecting Phytophthora sojae. For use in soil, adsorption properties need to be considered. Having low critical micelle concentrations, rhamnolipids tend to form micelles/aggregates with unknown effects on soil adsorption. Effects of soil pH, rhamnolipid congener structure, and concentration were examined. Congeners were identified and each quantitated for adsorptive partitioning. The adsorption isotherm at pH 6.5 showed a multi-stage profile plateauing at 1700 μg/g of soil. Less hydrophilic congeners adsorbed preferentially: R-C10-C12 > R-C10-C12:1 > RR-C10-C12:1 > RR-C10-C12 > R-C10-C10 > RR-C10-C10 > R-C8-C10 > RR-C8-C10 (where R is rhamnose and C# is the carbon number of β-hydroxy fatty acid). Adsorptive selectivity among congeners was very clear in dilute solutions but diminished with increasing concentrations. Results were interpreted with aggregate formation in solutions and on the soil surface. The cost estimate made accordingly supported the economic feasibility of rhamnolipid antizoosporic uses in soil.
Development of H-Specificity in A Substance by A-Decomposing Enzyme from Clostridium tertium A (1968)

A-decomposing enzyme from Cl. Tertium A can be fractionated into two principal fractions. One fraction, which is comprised solely of deacetylase, can destroy A activity of A substance or A red cells without enhancing their H activity. The other fraction, which is comprised principally of galactosaminidase containing deacetylase, can destroy A activity with enhancement of the H activity.
