Preparation of thin-film YBaCuO quantum interference devices with a lift-off technique (1988)

Highly textured and polycrystalline YBaCuO thin films were sputtered on cold MgO single-crystal substrates. After annealing in oxygen for 1 h at 920 °C, the films show critical temperatures Tc,end up to 74.5 K. Superconducting quantum interference devices (dc SQUID’s) structured in ≊1-μm-thick polycrystalline films with a lift-off technique exhibit a critical current of 2 mA at 5.5 K and 35 μA at 72 K. Voltage modulation can be observed at temperatures up to 63 K.
Evidence for a Role of Truncated trkC Receptor Isoforms in Mouse Development (1999)

The trkC locus encodes several receptors for neurotrophin-3, including the well studied full-length tyrosine kinase isoform, in addition to receptor isoforms lacking the kinase active domain. TrkC receptors are widely expressed throughout mouse development in many different organs. To investigate the function of truncated receptors in vivo and to identify cell types that are biologically responsive to this gene product, we have overexpressed a physiological truncated trkC isoform in the mouse. Mice overexpressing this receptor develop to term but die in the first postnatal days. High levels of transgene expression result in severe developmental defects in the peripheral nervous system and in the heart. The severity of neuronal losses observed in these animals suggests that truncated receptors may act by sequestering neurotrophin, thus, closely relating this mouse model to the neurotrophin-3-deficient one. Lower levels of exogenous truncated receptor in transgenic mice result in a more modest phenotype and, in some neuronal populations, do not cause neural deficits. Taken together, these data suggest that truncated trkC receptor isoforms may have modulatory functions in development.
Copper Precipitation Effects in Silicon Used in Solar Cells (1979)

Microstructural evaluation tests (e.g., TEM, SEM) were performed on copper‐doped p‐type silicon single‐crystal wafers before and after the solar cell fabrication. The copper concentration was 1015–1016 atoms/cm3. It was found that precipitates were formed during the growth process. No precipitates or other electrically active defects were detected in the solar cell junction depletion region. However, the copper precipitation in the bulk diminished the possibility of electrically active interstitial copper occurring in the lattice. These results explain the good electrical characteristics of the silicon solar cells under investigation.
Comparison of Workflow Scheduling Algorithms in Cloud Computing (2011)

Cloud computing has gained popularity in recent times. Cloud computing is internet based computing, whereby shared resources, software and information are provided to computers and other devices on demand, like a public utility. Cloud computing is technology that uses the internet and central remote servers to maintain data and applications. This technology allows consumers and businesses to use application without installation and access their personal files at any computer with internet access. The main aim of my work is to study various problems, issues and types of scheduling algorithms for cloud workflows as well as on designing new workflow algorithms for cloud Workflow management system. The proposed algorithms are implemented on real time cloud which is developed using Microsoft .Net Technologies. The algorithms are compared with each other on the basis of parameters like Total execution time, Execution time for algorithm, Estimated execution time. Experimental results generated via simulation shown that Algorithm 2 is much better than Algorithm 1, as it reduced makespan time.
A next generation, pilot-scale continuous sterilization system for fermentation media (2006)

A new continuous sterilization system was designed, constructed, started up, and qualified for media sterilization for secondary metabolite cultivations, bioconversions, and enzyme production. An existing Honeywell Total Distributed Control 3000-based control system was extended using redundant High performance Process Manager controllers for 98 I/O (input/output) points. This new equipment was retrofitted into an industrial research fermentation pilot plant, designed and constructed in the early 1980s. Design strategies of this new continuous sterilizer system and the expanded control system are described and compared with the literature (including dairy and bio-waste inactivation applications) and the weaknesses of the prior installation for expected effectiveness. In addition, the reasoning behind selection of some of these improved features has been incorporated. Examples of enhancements adopted include sanitary heat exchanger (HEX) design, incorporation of a "flash" cooling HEX, on-line calculation of F(o) and R(o), and use of field I/O modules located near the vessel to permit low-cost addition of new instrumentation. Sterilizer performance also was characterized over the expected range of operating conditions. Differences between design and observed temperature, pressure, and other profiles were quantified and investigated.
OPTIMIZATION OF THE CONDITIONS REQUIRED FOR CHEMICAL AND BIOLOGICAL MODIFICATION OF THE YEAST WASTE FROM BEER MANUFACTURING TO PRODUCE ADHESIVE COMPOSITIONS (2012)

During the production of beer large amounts of yeast waste are generated. This paper considers the possible making of environmentally friendly adhesive compositions from such wastes. Chemical treatment of yeast wastes increases their adhesive characteristics. Chemical crosslinking with glutaric aldehyde and biological cross-linking by enzyme transglutaminase improves the moisture resistance of the adhesive compositions. In terms of their physical and mechanical parameters they are not inferior to glues of natural origin and can be used for bonding paper, cardboard, and wood. The bonding strength of paper was 421.8 N / m, and that of wood was 27.8 MPa.
Dynamic queue assignment in a VC queue manager for gigabit ATM networks (2002)

Today, ATM networks are being used to carry bursty data traffic with large and highly variable transmission rates, and burst sizes ranging from kilobytes to megabytes. Obtaining good statistical multiplexing performance for this kind of traffic requires much larger buffers than are needed for more predictable applications or for bursty data applications with more limited burst transmission rates. Large buffers lead to large queueing delays, making it necessary for switches to implement more sophisticated queueing mechanisms in order to deliver acceptable quality of service (QoS). This paper describes a 2.4 Gb/s ATM queue management chip that has practically unlimited buffer scaling and also supports dynamic per VC queueing, an efficiently implementable form of weighted round-robin scheduling, a novel packet-level discarding algorithm and the ability to support multiple output links. We give a detailed description of the dynamic queue assignment mechanism, which allows the chip to support both virtual path and virtual circuit channels. This mechanism is self-configuring, eliminating the need to configure the range of VCIs associated with a given VPI, and makes optimal use of the chip's per-channel data structures, since these data structures can be assigned only when cells are present in the queues.

Robust Wide Visible-Light-Responsive Photoactivity for H<sub>2</sub> Production over a Polymer/Polymer Heterojunction Photocatalyst: The Significance of Sacrificial Reagent (2015)

A robust polymer/polymer surface heterojunction (SHJ) catalyst for wide visible-light-driven H2 production is fabricated by a facile rotary evaporation of poly(3-hexylthiophene) (P3HT) solution containing graphitic carbon nitride (g-C3N4). The photocatalytic H2 production activity of the obtained SHJ catalyst (P3HT/g-C3N4) is significantly affected by the types of sacrificial reagents, and ascorbic acid (AA) shows the best photoactivity among the commonly used sacrificial reagents. The SHJ catalyst containing 3 wt % P3HT gives a H2 evolution activity up to 3045 μmol/h in a saturated AA solution, which is ∼491 times higher than that (6.2 μmol/h) of P3HT/g-C3N4 without AA solution under λ ≥ 500 nm light irradiation. Especially, the SHJ catalyst containing 3 wt % P3HT shows a record apparent quantum yield (AQY) of 77.4% at 420 nm light irradiation in the field of g-C3N4-based catalyst, and wide visible/NIR-light-responsive ability with AQY of 59.4%, 20.2%, 3.2% and 0.68% at 500, 600, 700 and 800 nm monochromatic light irradiation, respectively. The extremely high photoactivity is caused by the wide visible-light absorption, efficient charge transfer at the interface of P3HT/g-C3N4 and suitable oxidation half-reaction caused by the added AA as a sacrificial reagent. This study not only demonstrates a new direction for the solar fuel conversion over the large family of polymer-based semiconductors but also emphasizes the importance of oxidation half-reaction caused by the sacrificial reagent, which can significantly affect the photoactivity for H2 production.

K <sup>+</sup> /Na <sup>+</sup> -triggered bioluminescence in the oceanic squid <i>Symplectoteuthis oualaniensis</i> (1981)

A distinctive type of luminescent system present in the large dorsal luminous organ of the oceanic squid Symplectoteuthis oualaniensis is described. The organ produces an intense blue flash of light followed by a rapid decay in light intensity. Luminescence originates from numerous oval granules present in the luminous organ. The essential light-emitting components are membrane bound. Intact granules or washed homogenates of the granules are triggered to emit light by monovalent cations such as, in decreasing order of effectiveness, potassium, rubidium, sodium, cesium, ammonium, and lithium. Calcium, magnesium, and strontium ions do not trigger light emission. Analysis of the kinetics of the decay of light intensity suggests that two light-emitting components are involved, one decaying faster than the other. The light-emitting reaction has an absolute requirement for molecular oxygen. The optimum KCl or NaCl concentration is approximately 0.6 M and the optimum pH is approximately 7.8. A free sulfhydryl group is essential for activity.
Vectorial summation of probabilistic current harmonics in power systems: From a bivariate distribution model towards a univariate probability function (2000)

Abstract This paper extends the investigation into the bivariate normal distribution (BND) model which has been widely used to study the asymptotic behaviour of the sum of a sufficiently large number of randomly‐varying harmonic phasors (of the same frequency). Although the BND model is effective and applicable to most problems involving harmonic summation, its main drawback resides in the computation time required to extract the probability density function of the harmonic magnitude from the two‐dimensional BND model. This paper proposes a novel approach to the problem by assimilating the generalized Gamma distribution (GGD) model to the marginal distribution (the magnitude) of the BND using the method of moments. The proposed method can accurately estimate the parameters of the GGD model without time‐consuming calculation. A power system containing ten harmonic sources is taken as an example where the comparison of the Monte‐Carlo simulation, the BND model and the GGD model is given and discussed. The comparison shows that the GGD model approximates the BND model very well.
Glass pipette-carbon fiber microelectrodes for evoked potential recordings (1997)

Current methods for recording field potentials with tungsten electrodes make it virtually impossible to use the same recording electrode also as a lesioning electrode, for example for histological confirmation of the recorded site, because the lesioning procedure usually wears off the tungsten tip. Therefore, the electrode would have to be replaced after each lesioning procedure, which is a very high cost solution to the problem. We present here a low cost, easy to make, high quality glass pipette-carbon fiber microelectrode that shows resistive, signal/noise and electrochemical coupling advantages over tungsten electrodes. Also, currently used carbon fiber microelectrodes often show problems with electrical continuity, especially regarding electrochemical applications using a carbon-powder/resin mixture, with consequent low performance, besides the inconvenience of handling such a mixture. We propose here a new method for manufacturing glass pipette-carbon fiber microelectrodes with several advantages when recording intracerebral field potentials.
A Study of the Evolution of Inverted-Topology Repeats from LeuT-Fold Transporters Using AlignMe (2010)

X-ray crystal structures have revealed that numerous secondary transporter proteins originally categorized into different sequence families share similar structures, namely, the LeuT fold. The core of this fold consists of two units of five transmembrane helices, whose conformations have been proposed to exchange to form the two alternate states required for transport. That these two units are related implies that LeuT-like transporters evolved from gene-duplication and fusion events. Thus, the origins of this structural repeat may be relevant to the evolution of transport function. However, the lack of significant sequence similarity requires sensitive sequence search methods for analyzing their evolution. To this end, we developed a software application called AlignMe, which can use various types of input information, such as residue hydrophobicity, to perform pairwise alignments of sequences and/or of hydropathy profiles of (membrane) proteins. We used AlignMe to analyze the evolutionary relationships between repeats of the LeuT fold. In addition, we identified proteins from the so-called DedA family that potentially share a common ancestor with these repeats. DedA domains have been implicated in, e.g., selenite uptake; they are found widely distributed across all kingdoms of life; two or more DedA domains are typically found per genome, and some may adopt dual topologies. These results suggest that DedA proteins existed in ancient organisms and may function as dimers, as required for a would-be ancestor of the LeuT fold. In conclusion, we provide novel insights into the evolution of this important structural motif and thus potentially into the alternating-access mechanism of transport itself.
Purification and Characterization of Protease Produced by Aspergillus wentti Isolated from Korean Traditional Meju (2000)

The protease produced by a newly isolated Aspergillus wentti from Korean traditional Meju was purified and characterized. The optimal medium composition and culture conditions for maximum protease production were ; bran :1% glucose solution =1 : 1, pH 9.0, , and 4 days of fermentation. Protease was purified by QAE-Sephadex, SP-Sephadex ion exchange chromatography and Sephadex G-100 chromatography. The specific activity and the purification fold of the purified enzyme were 213 unit/mg protein and 27.3, respectively. The molecular weight of purified protease was found to be 32 kDa by SDS-PAGE. Km and Vmax value's for hammastein milk casein were , respectively. Kinetic parameters showed that the enzyme has higher affinity to casein than isolated soybean protein, hemoglobin and bovine serum albumin. Optimal pH and temperature for reaction of the purified enzyme were 9.0 and , respectively. The enzyme was stable at pH 4.0-11.0, below , and the activity was not stimulated by metal ions. 1mM phenylmethylsulfonyl fluoride inhibited the enzyme activity by 98.5%. It means that the enzyme is one of serine protease.
STATISTICAL ASPECTS OF DOUBLE ISOTOPE LIQUID SCINTILLATION COUNTING BY INTERNAL STANDARD TECHNIQUE (1964)

Equations were derived for calculation of the error in the disintegration rates of two isotopes in a mixture. The way in which the equations can be used to determine useful internal standard activities, channel settings, and isotope ratios is shown. For mixtures of carbon-14 and tritium, internal standard activities of 50,000-- 100,000 dpm for carbon-14 and 100,000-- 150,000 dpm for tritium are useful as single routine quantities. A 1-minute counting time after internal standard addition is routinely adequate. (auth)
Sediment Feed and Recirculating Flumes: Fundamental Difference (1993)

Two standard modes of laboratory sediment transport flume operation are sediment‐feed and recirculating. In the case of uniform sediment, the final equilibriums achieved in the two modes are equivalent and independent of initial conditions, even though the specified flow and sediment constraints differ. When the sediment consists of a mixture of sizes, however, this symmetry breaks down. In a sediment‐feed flume, both the feed rate and size distribution are specified by the user, and must be identical to those of the bed load at final equilibrium. The final state thus becomes independent of initial conditions. In a recirculating flume, however, the equilibrium size distribution of neither the bed load nor the bed surface material can be specified in advance. As a result, the final state depends on the initial conditions and can include the possibility of partial transport. The equilibriums themselves are equivalent in that they obey the same laws of flow and sediment transport. Their a‐priori predictability, however, differs due to the difference in governing constraints. When fractional transport is scaled by the bulk size distribution, the two flume modes may produce very different transport relations, even for the same sediment. A consistent approach requires that the transport be scaled by the size distribution of the bed surface.
Characterization of Stg Fimbriae from an Avian Pathogenic <i>Escherichia coli</i> O78:K80 Strain and Assessment of Their Contribution to Colonization of the Chicken Respiratory Tract (2006)

In a previous study, ecs-3, a sequence from avian pathogenic Escherichia coli (APEC) O78:K80 strain chi7122, was found to be expressed in vivo in infected chicken tissues. The region encompassing ecs-3 carries a fimbrial gene cluster that is a putative ortholog of the stg fimbrial gene cluster of Salmonella enterica serovar Typhi. This APEC fimbrial gene cluster, which we have termed stg, is a member of a distinct group of related fimbriae that are located in the glmS-pstS intergenic region of certain E. coli and S. enterica strains. Under the control of the pBAD promoter, the production of Stg fimbriae was demonstrated by Western blotting and immunogold electron microscopy with E. coli K-12. Transcriptional fusions suggest that stg expression is influenced by the carbohydrate source and decreased by the addition of iron and that Fur plays a role in the regulation of stg expression. stg sequences were associated with APEC O78 isolates, and stg was phylogenetically distributed among E. coli reference strains and clinical isolates from human urinary tract infections. Stg fimbriae contributed to the adherence of a nonfimbriated E. coli K-12 strain to avian lung sections and human epithelial cells in vitro. Coinfection experiments with APEC strain chi7122 and an isogenic Deltastg mutant demonstrated that compared to the wild-type parent, the Deltastg mutant was less able to colonize air sacs, equally able to colonize lungs, and able to more effectively colonize tracheas of infected chickens. Stg fimbriae, together with other adhesins, may therefore contribute to the colonization of avian respiratory tissues by certain APEC strains.

A Hominoid Genus from the Early Miocene of Uganda (1997)

Fossils from a large-bodied hominoid from early Miocene sediments of Uganda, along with material recovered in the 1960s, show features of the shoulder and vertebral column that are significantly similar to those of living apes and humans. The large-bodied hominoid from Uganda dates to at least 20.6 million years ago and thus represents the oldest known hominoid sharing these derived characters with living apes and humans.
A self-assembled molecular team of boronic acids at the gold surface for specific capture of cis-diol biomolecules at neutral pH (2011)

We report a single-step strategy called self-assembled molecular team to generate boronate affinity ligands that can specifically capture cis-diol biomolecules at neutral pH, which provides three significant advantages: a simple procedure, high affinity and high specificity.
Anaemia and zidovudine‐containing antiretroviral therapy in paediatric antiretroviral programmes in the IeDEA Paediatric West African Database to evaluate AIDS (2013)

Severe anaemia is frequent at baseline and guides the first-line ART prescription, but its incidence seems rare among children on ART. Severe malnutrition at baseline is a strong predictor for development of severe anaemia, and interventions to address this should form an integral component of clinical care.
Magnetized target fusion: An ultra high energy approach in an unexplored parameter space (1994)

Magnetized target fusion is a concept that may lead to practical fusion applications in a variety of settings. However, the crucial first step is to demonstrate that it works as advertised. Among the possibilities for doing this is an ultrahigh energy approach to magnetized target fusion, one powered by explosive pulsed power generators that have become available for application to thermonuclear fusion research. In a collaborative effort between Los Alamos and the All-Russian Scientific Institute for Experimental Physics (VNIIEF) a very powerful helical generator with explosive power switching has been used to produce an energetic magnetized plasma. Several diagnostics have been fielded to ascertain the properties of this plasma. We are intensively studying the results of the experiments and calculationally analyzing the performance of this experiment.
