Mannityl opine analogs allow isolation of catabolic pathway regulatory mutants (1984)

Five virulent Agrobacterium spp. strains that can catabolize the mannityl opines mannopine (MOP), mannopinic acid ( MOA ), and agropinic acid (AGA) were tested for their ability to grow on analogs of these compounds. Analogs containing alternative amino acids replacing glutamic acid or glutamine were generally refused by these bacteria, but mutants were obtained that catabolized the entire family of analogs. In the case of strain C58C1 (pRi 8196), we demonstrated that typical mutants were constitutive for MOP uptake, whereas the wild-type parent was inducible by MOP. Analogs of MOA prepared from a variety of sugars instead of mannose were generally refused, except for a strain carrying pTi B6-806, which grew well on all such analogs. The analogs allowed selection of mutants of all strains. Although most wild-type strains were inducible for AGA uptake, typical mutants selected from strain C58C1 (pRi 8196) were found to be constitutive for uptake of AGA, as was the wild-type strain carrying pTi B6-806. Such constitutive mutants grew on all sugar analogs of MOP, MOA , and AGA tested. The pTi B6-806-containing strain was tested for growth on a more extended series of analogs, including tetrose , triose, diose , and disaccharide analogs, all of which were accepted. Only ketose analogs were refused. Selection of promiscuous regulatory mutants by the two types of opine analogs suggests that the repressor proteins of MOP and AGA permease/ catabolase systems are chiefly responsible for the specificity of the pathways.
Novel Detection Method of High Voltage Power Metering Circuit Fault based on Electric Energy Meter Phase and Voltage Transformer (2016)

The basic structure of the electromagnetic induction type voltage transformer is the core and primary, secondary winding. Characteristics of capacity are small and relatively constant. This paper introduces the application of electric energy meter, including two kinds of three-phase electric energy meter (three-phase two elements and three element phase) and non reactive energy meter. In this paper, the high voltage electric energy metering system of fault conditions is analyzed. The paper presents novel method of high voltage power metering circuit fault detection based on Electric energy meter phase and voltage transformer. The voltage circuit fault that electric energy meter pressure loss, less pressure fault detection method is analyzed.
Syk tyrosine kinase participates in β<sub>1</sub>-integrin signaling and inflammatory responses in airway epithelial cells (2004)

The protein tyrosine kinase Syk is critically involved in immunoreceptor signaling in hematopoietic cells. Recent studies demonstrate Syk expression in nonhematopoietic cells, including fibroblasts, endothelial cells, hepatocytes, and breast epithelium. However, the role of Syk in these cells is uncertain. We hypothesized that Syk is expressed in respiratory epithelial cells (EC) and that it functions as a signaling molecule involved in inflammatory responses in the epithelium. With the use of immunohistochemistry, Western blot, PCR, and laser scanning confocal microscopy, Syk was detected in human, rat, and mouse bronchial epithelium in situ and in cultured human bronchial EC in primary cells and the cell lines HS-24 and BEAS-2B. Syk-dependent signaling pathways in EC were initiated by engagement of beta1-integrin receptors. Stimulation of beta1-integrin receptors by fibronectin or antibody cross-linking caused redistribution of Syk from a cytoplasmic to plasma membrane localization. In stimulated cells, Syk and beta1-integrin colocalized. In addition, following beta1-integrin receptor engagement, tyrosine phosphorylation of Syk was observed. Expression of the intercellular adhesion molecule-1 (ICAM-1) and production of IL-6, both important molecules in lung inflammation, was downregulated in EC treated with Syk small interfering RNA or Syk inhibitor piceatannol. We propose that Syk is involved in signaling pathways induced by integrin engagement in airway EC. Syk-mediated signaling regulates IL-6 and ICAM-1 expression and may be important in the pathophysiology of lung inflammation.

권리금 계약 당사자에 관한 연구 - 상가임대차법 개정안 중 권리금에 관한 정의를 중심으로 (2015)

권리금의 수수는 상가임대차 시장에서 금액이나 의미 등을 고려할 때 중요한 비중을 차지하고 있다. 그러나 당해 시장에서 오랜 기간 동안 반복된 행위로서 판례도 인정하고 있음에도 불구하고 여러 가지 이유로 인하여 지금까지 법의 사각지대에 놓여 있었으며, 이로 인하여 지속적으로 임차인보호 문제가 제기되었다. 이러한 현실적인 요구에 의하여 법무부는 최근 상가건물임대차보호법 개정안을 발표하였는데, 무엇보다도 권리금을 제도권에 편입시킨 것은 시사하는 바가 크다고 생각한다. 그러나 이러한 노력에도 불구하고 현행 개정안은 권리금 계약의 당사자를 현실과 다르게 규정함으로써 여전히 현실을 반영하지 못하고 있으며, 향후 예견되는 문제 해결에 있어서도 미흡하다고 판단된다. 이러한 연구의 필요성에 의하여 실태조사 . 판례 및 입법례를 살펴본 결과 다음과 같은 결론을 얻을 수 있었다. 현재의 문제뿐만 아니라 발생할 것으로 예견되는 다양한 문제에 대처하기 위하여 무엇보다도 권리금 계약의 당사자를 어떻게 규정할 것인가의 문제는 중요한 부분이다. 그러므로 현재와 같이 권리금문제의 발생 주체를 임대인과 임차인으로 한정하기 보다는 임대인과 이해관계인의 관계로 확대함으로써 새로운 임차인이 포함되도록 규정하는 것이 타당하다고 생각한다. 요컨대, 이러한 입법적 해결노력은 당해 규정이 현실을 더욱 잘 설명하며 보다 설득력 있는 제도로 나아가는데 기여할 것으로기대된다.
On-the-fly Large-scale Channel-Gain Estimation for Massive Antenna-Array Base Stations (2018)

We propose a novel scheme for estimating the large-scale gains of the channels between user terminals (UTs) and base stations (BSs) in a cellular system. The scheme leverages TDD operation, uplink (UL) training by means of properly designed non-orthogonal pilot codes, and massive antenna arrays at the BSs. Subject to Q resource elements allocated for UL training and using the new scheme, a BS is able to estimate the large-scale channel gains of K users transmitting UL pilots in its cell and in nearby cells, provided K<=Q^2. Such knowledge of the large-scale channel gains of nearby out-of-cells users can be exploited at the BS to mitigate interference to the out-of-cell users that experience the highest levels of interference from the BS. We investigate the large-scale gain estimation performance provided by a variety of non-orthogonal pilot codebook designs. Our simulations suggest that among all the code designs considered, Grassmannian line-packing type codes yield the best large-scale channel gain estimation performance.
SA11 Rotavirus Is Specifically Inhibited by an Acetylated Sialic Acid (1990)

Bovine salivary mucin (BSM) inhibits rotavirus replication in vitro and in vivo. The inhibitory effect of BSM in vitro is abolished by Arthrobacter ureafaciens neuraminidase but not by Clostridia perfringens neuraminidase; it is abolished by mild base deacetylation but not by influenza C acetylesterase. The data suggest that SA11 rotavirus binds to a specific sialic acid structure on BSM different from the sialic acids recognized by other viruses.
S-layer gene sbsC of Bacillus stearothermophilus ATCC 12980: molecular characterization and heterologous expression in Escherichia coli The GenBank accession number for the sequence described in this paper is AF055578. (2000)

The cell surface of Bacillus stearothermophilus ATCC 12980 is completely covered with an oblique S-layer lattice. To investigate sequence identities and a common structure-function relationship in S-layer proteins of different B. stearothermophilus wild-type strains, the nucleotide sequence encoding the S-layer protein SbsC of B. stearothermophilus ATCC 12980 was determined by PCR techniques. The entire sbsC sequence showed an ORF of 3297 bp predicted to encode a protein of 1099 aa with a theoretical molecular mass of 115409 Da and an isoelectric point of 5.73. Primer extension analysis suggested the existence of two promoter regions. Amino acid sequence comparison between SbsC and SbsA, a previously characterized S-layer protein of B. stearothermophilus PV72/p6 which assembles into a hexagonally ordered lattice, revealed an identical secretion signal peptide, 85% identity for the N-terminal regions (aa 31-270) which do not carry any S-layer homologous motifs, but only 21% identity for the rest of the sequences. Affinity studies demonstrated that the N-terminal part of SbsC is necessary for recognition of a secondary cell wall polymer. This was in accordance with results obtained in a previous study for SbsA, thus confirming a common functional principle for the N-terminal parts of both S-layer proteins. The sbsC coding region cloned into the pET3a vector without its own upstream region, the signal sequence and the 3' transcriptional terminator led to stable expression in Escherichia coli.
Solution-Phase Synthesis of a 1,5-Dialkylamino-2,4-dinitrobenzene Library and the Identification of Novel Antibacterial Compounds from This Library (2000)

In this report we demonstrate that a 1,5-dialkylamino-2,4-dinitrobenzene small molecule library can be generated by a highly efficient solution-phase synthesis method. From this 2485-member library, a series of novel compounds with antibacterial activity were isolated. The significance of this report is that the synthetic scheme is extremely simple, with minimal number of liquid handling steps, and the solvents and reagents left in the final library preparation are fully compatible with cell-based assays.
Parallel coarse‐grid selection (2007)

Abstract Algebraic multigrid (AMG) is a powerful linear solver with attractive parallel properties. A parallel AMG method depends on efficient, parallel implementations of the coarse‐grid selection algorithms and the restriction and prolongation operator construction algorithms. In the effort to effectively and quickly select the coarse grid, a number of parallel coarsening algorithms have been developed. This paper examines the behaviour of these algorithms in depth by studying the results of several numerical experiments. In addition, new parallel coarse‐grid selection algorithms are introduced and tested. Copyright © 2007 John Wiley & Sons, Ltd.
Near neighbor join (2014)

An increasing number of Web applications such as friends recommendation depend on the ability to join objects at scale. The traditional approach taken is nearest neighbor join (also called similarity join), whose goal is to find, based on a given join function, the closest set of objects or all the objects within a distance threshold to each object in the input. The scalability of techniques utilizing this approach often depends on the characteristics of the objects and the join function. However, many real-world join functions are intricately engineered and constantly evolving, which makes the design of white-box methods that rely on understanding the join function impractical. Finding a technique that can join extremely large number of objects with complex join functions has always been a tough challenge. In this paper, we propose a practical alternative approach called near neighbor join that, although does not find the closest neighbors, finds close neighbors, and can do so at extremely large scale when the join functions are complex. In particular, we design and implement a super-scalable system we name SAJ that is capable of best-effort joining of billions of objects for complex functions. Extensive experimental analysis over real-world large datasets shows that SAJ is scalable and generates good results.
Regression Analysis for ATM Cash Flow Prediction (2017)

One of the most challenging task for a bank is to maintain cash in their ATMs (Automated Teller Machines) so that they can easily serve their customers. To solve this problem, they create a daily estimate for each of their ATM, which can result into “Out of Cash” or “Over Stock” situations. This requires a solution which can resonably predict how much cash inflow would be needed for the next day by examining and learning from past transactional data. We present results for regression techniqes, including using the LSTM model for time-series for the first time to the best of our knowledge, to solve the “Cash Estimation” problem. This would allow banks to adopt to the changing needs of cash according to specific occasions, holidays, etc. The dataset that we would be using is transaction record for past 2.5 years for ATMs situated in a busy district of Karachi, Pakistan. This research will help banks in effectively reducing extra cost error which they bear for maintenance of their cash as well as increasing customer satisfaction.
A Three Dimensional Multi‐Layered Sliding Triboelectric Nanogenerator (2014)

A novel design of a 3D triboelectric nanogenerator (TENG) is demonstrated. Because of its largely increased friction areas, the device has a multi-layered structure, high transferred-charge-quantity, and current output. It delivers an open-circuit voltage of 800 V, a short-circuit current density of 5.5 mA m-2 with a maximum instantaneous power of 4.4 W m-2. This represents important progress toward practical applications in self-powered technologies.
Cloning of a Novel Pyrethroid-Hydrolyzing Carboxylesterase Gene from <i>Sphingobium</i> sp. Strain JZ-1 and Characterization of the Gene Product (2009)

A novel esterase gene, pytH, encoding a pyrethroid-hydrolyzing carboxylesterase was cloned from Sphingobium sp. strain JZ-1. The gene contained an open reading frame of 840 bp. Sequence identity searches revealed that the deduced enzyme shared the highest similarity with many alpha/beta-hydrolase fold proteins (20 to 24% identities). PytH was expressed in Escherichia coli BL21 and purified using Ni-nitrilotriacetic acid affinity chromatography. It was a monomeric structure with a molecular mass of approximately 31 kDa and a pI of 4.85. PytH was able to transform p-nitrophenyl esters of short-chain fatty acids and a wide range of pyrethroid pesticides, and isomer selectivity was not observed. No cofactors were required for enzyme activity.

A new technique for radiolabelling of humic substances (2004)

Abstract A new method of radiolabelling of humic substances (HS) in the aqueous phase has been developed. Radiolabelling with the short-lived positron-emitter 18 F was carried out via diazonium coupling to electron-rich aromatic residues of the humic substances. Labelling yields of up to 75% were obtained after optimization of the synthetic procedure. Introductory experimental steps were performed for testing the labelling stability of the humic substances with ultrafiltration, electrophoretic and chromatographic methods.
Power sources for unmanned underwater vehicles (2002)

The power source of an underwater vehicle is the main component that determines its range of travel and the tasks that it can perform. Until recently, the choice of practical power sources for most applications was limited to lead--acid and silver--zinc batteries. Lead--acid batteries are a well-established technology and are available at low cost. However, they have a low energy density (∼25 Wh kg−1). Although silver-zinc batteries have a much higher energy density (∼120 Wh kg−1), they are expensive, and have a short life of 40--100 cycles compared to 1000 cycles for lead--acid (Carey et al., 1992). There is, in practice, no all-purpose, ideal choice of power source for an autonomous underwater vehicle (AUV). Developers have sought to use a variety of battery types including nickel--cadmium, nickel--metal hydride, lithium ion and primary manganese alkaline and lithium cells, often using stacks of cells developed for the consumer or industrial markets. In recent years considerable research and development work has been done on advanced power sources for road electric and hybrid vehicles. This on-going work is motivated by environmentally driven legislation aimed at reducing the harmful emissions of conventional internal combustion engine vehicles (e.g. IEA, 1993). Many in the AUV community have an expectation that breakthroughs and or cost reduction in electric power for road vehicles may deliver the ideal AUV power source. However, this potentially advantageous spin-off may prove difficult to achieve in practice. Electric cars need sources capable of delivering 5--50 kW at a capital cost per kW not too dissimilar from that of an internal combustion engine. In contrast, most AUVs have a power consumption an order of magnitude less, typically 0.2--2 kW. Furthermore, the AUV user would be willing to pay a higher price per kW than the car owner would. Much research and development effort is also directed at providing high energy density sources for low power consumption devices. For example, micro-fuel cells are becoming available for portable electronic equipment such as cellular telephones and laptop computers requiring 5--50 W. For these, the consumer is prepared to pay an even higher price per kW than the AUV user. The ideal power source for an AUV should have a high energy density, high power density (higher charge and discharge rates), low cost, long life, low maintenance, high efficiency and wide operating temperature range. It should be safe
Clustering initialization based on spatial information for speaker diarization of meetings (2008)

This paper proposes an initialization for an agglomerative\nsystem applied to speaker diarization in the meeting environment.\nThe initialization is based on a previous clustering of the\ntemporal sequence generated by the estimation of the Time Delay\nof Arrival (TDOA) among pair of sensors. That initial clustering\nhas the purpose of obtaining initial classes with speaker\ninformation from a sole speaker. The aim is to ensure the purity\nof the initial segments based on the position of the speakers in\na meeting along time. The TDOA initialization was tested with\nthe dataset used in the RT07s evaluation where an improvement\nof the diariazation error rate is obtained with respect to the classical\nuniform initialization. The most of the experiments show\nthat the purity of the beginning segments leads to a better clustering\non the posterior hierarchical strategy based on cepstral\nfeatures.

Postinduction Dexamethasone and Individualized Dosing of <i>Escherichia Coli</i> L-Asparaginase Each Improve Outcome of Children and Adolescents With Newly Diagnosed Acute Lymphoblastic Leukemia: Results From a Randomized Study—Dana-Farber Cancer Institute ALL Consortium Protocol 00-01 (2013)

There was no overall difference in skeletal toxicity by corticosteroid type; dexamethasone was associated with more infections and, in older children, increased incidence of osteonecrosis and fracture. There was no difference in asparaginase-related toxicity by EC-Asnase dosing method. Dexamethasone and ID EC-Asnase were each associated with superior EFS. Monitoring NSAA during treatment with EC-Asnase may be an effective strategy to improve outcome in pediatric ALL.
Generation of phytate-free seeds in <i>Arabidopsis</i> through disruption of inositol polyphosphate kinases (2005)

Phytate (inositol hexakisphosphate, IP6) is a regulator of intracellular signaling, a highly abundant animal antinutrient, and a phosphate store in plant seeds. Here, we report a requirement for inositol polyphosphate kinases, AtIPK1 and AtIPK2beta, for the later steps of phytate synthesis in Arabidopsis thaliana. Coincident disruption of these kinases nearly ablates seed phytate without accumulation of phytate precursors, increases seed-free phosphate by 10-fold, and has normal seed yield. Additionally, we find a requirement for inositol tetrakisphosphate (IP4)/inositol pentakisphosphate (IP5) 2-kinase activity in phosphate sensing and root hair elongation. Our results define a commercially viable strategy for the genetic engineering of phytate-free grain and provide insights into the role of inositol polyphosphate kinases in phosphate signaling biology.
The study of preparation of AlN powder (2002)

Highly purified fine AlN powder was synthesized with low oxygen content. The optimal raw materials were Al/sub 2/O/sub 3/ dehydrated from Al(OH)/sub 3/, carbon black, and AlN seed crystal, and their weight proportion was 1:0.5:0.01, respectively. Appropriate addition of AlN seed crystals might make the product finer. The order of the reaction was zero whose rate constants were 0.23 mol/L-s at 1400 degrees C and 0.48 mol/L-s at 1500 degrees C. AlN powder obtained at 1400 degrees C was in the small size with regular shape and narrow size distribution. The product was fine too at 1500 degrees C and a large amount of it possessed a hexagonal form. When the reaction was nearing completion, the baked powder was treated at depressed pressure to reduce the residual oxygen. Then the end-product was prepared containing 33.5% nitrogen, 0.4% oxygen, and 0.11% carbon (total) with an average particle size of 2-4 mu m.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Detection of U.S. Traffic Signs (2015)

This paper presents a comprehensive research study of the detection of U.S. traffic signs. Until now, the research in Traffic Sign Recognition systems has been centered on European traffic signs, but signs can look very different across different parts of the world, and a system that works well in Europe may indeed not work in the U.S. We go over the recent advances in traffic sign detection and discuss the differences in signs across the world. Then we present a comprehensive extension to the publicly available LISA-TS traffic sign data set, almost doubling its size, now with high-definition-quality footage. The extension is made with testing of tracking sign detection systems in mind, providing videos of traffic sign passes. We apply the Integral Channel Features and Aggregate Channel Features detection methods to U.S. traffic signs and show performance numbers outperforming all previous research on U.S. signs (while also performing similarly to the state of the art on European signs). Integral Channel Features have previously been used successfully for European signs, whereas Aggregate Channel Features have never been applied to the field of traffic signs. We take a look at the performance differences between the two methods and analyze how they perform on very distinctive signs, as well as white, rectangular signs, which tend to blend into their environment.
