A True Time Delay-based SiGe Bi-directional T/R Chipset for Large-Scale Wideband Timed Array Antennas (2018)

This paper presents a true time delay (TTD)-based transmit/receive (T /R) chipset with 508 ps time delay and 31.5 dB amplitude control for large-scale wideband timed array. The proposed T /R chipset consists of a true time delay circuit, a switched T -type attenuator, and digital control circuits. To compensate the frequency dependent insertion loss characteristics of single-pole double-throw switches, artificial transmission line (ATL), passive-based attenuator, and wideband bi-directional active double-pole double-throw (DPDT) switches are included in the design. In addition, low-path filters (LPFs) with T -type attenuators are applied to the reference signal path to minimize amplitude variations during time delay control. The proposed T /R chipset demonstrates a record delay-range bandwidth product and a flat in-band characteristic of -3.6 dB with ±3.6 dB variation in both operations (transmit and receive) over 2-20 GHz.
Physical-layer network coding with partial CSI (2010)

In this paper, we investigate the physical-layer network coding (PNC) with partial channel state information (CSI) in the context of two way relay communication. We consider the typical scenario that one end node exchanges information with another via a relay without knowing the CSI knowledge between the relay and the other end node. A relay scheme called power weighted mapping (PWM) is proposed to implement the PNC with partial CSI, which is actually working by mapping the observations at the relay to a specific sending constellation. For the case of QPSK modulations at the end nodes, we develop another two relay schemes called 3QAM mapping (3QAMM) scheme and QPSK mapping (QPSKM) scheme to improve the performance, under the principle of increasing the minimum distance of the constellation at the relay. The simulation results demonstrate the effective of our proposed schemes, which greatly reduce the system load while still reserve high performance of about only 1dB performance loss compared with the schemes with full CSI.
Genomic Analysis of<i>Clostridium perfringens</i>Bacteriophage φ3626, Which Integrates into<i>guaA</i>and Possibly Affects Sporulation (2002)

Two temperate viruses, phi3626 and phi8533, have been isolated from lysogenic Clostridium perfringens strains. Phage phi3626 was chosen for detailed analysis and was inspected by electron microscopy, protein profiling, and host range determination. For the first time, the nucleotide sequence of a bacteriophage infecting Clostridium species was determined. The virus belongs to the Siphoviridae family of the tailed phages, the order Caudovirales. Its genome consists of a linear double-stranded DNA molecule of 33,507 nucleotides, with invariable 3'-protruding cohesive ends of nine residues. Fifty open reading frames were identified, which are organized in three major life cycle-specific gene clusters. The genes required for lytic development show an opposite orientation and arrangement compared to the lysogeny control region. A function could be assigned to 19 gene products, based upon bioinformatic analyses, N-terminal amino acid sequencing, or experimental evidence. These include DNA-packaging proteins, structural components, a dual lysis system, a putative lysogeny switch, and proteins that are involved in replication, recombination, and modification of phage DNA. The presence of genes encoding a putative sigma factor related to sporulation-dependent sigma factors and a putative sporulation-dependent transcription regulator suggests a possible interaction of phi3626 with onset of sporulation in C. perfringens. We found that the phi3626 attachment site attP lies in a noncoding region immediately downstream of int. Integration of the viral genome occurs into the bacterial attachment site attB, which is located within the 3' end of a guaA homologue. This essential housekeeping gene is functionally independent of the integration status, due to reconstitution of its terminal codons by phage sequence.
Diseased Tissue Identification And Quantification Utilizing MRI (2005)

This paper describes the development of a Physician's Workstation (PWS) for the evaluation of soft tissue types utilizing MR, which includes the analysis, quantification and 3-D visualization of the pertinent tissues. A major theme underlying our work is that it is possible to develop robust image processinglpattem recognition algorithms for the evaluation of diseased tissue by focusing on specific diseases involving localized regions of the body obtained with consistent and well developed imaging protocols. We have implemented two specific image processinglpattem recognition and display systems for (1) the evaluation of atherosclerosis; and (2) the differentiation of breast lesions.
Cloning of Syrian Hamster (<i>Mesocricetus auratus</i>) Cytokine cDNAs and Analysis of Cytokine mRNA Expression in Experimental Visceral Leishmaniasis (1998)

ABSTRACT The Syrian golden hamster ( Mesocricetus auratus ) is uniquely susceptible to a variety of intracellular pathogens and is an excellent model for a number of human infectious diseases. The molecular basis for this high level of susceptibility is unknown, and immunological studies related to this model have been limited by the lack of available reagents. In this report we describe the cloning and sequence analysis of portions of the Syrian hamster interleukin 2 (IL-2), IL-4, gamma interferon (IFN-γ), tumor necrosis factor alpha, IL-10, IL-12p40, and transforming growth factor β cDNAs. In addition, we examined the cytokine response to infection with the intracellular protozoan Leishmania donovani in this animal model. Sequence analysis of the hamster cytokines revealed 69 to 93% homology with the corresponding mouse, rat, and human nucleotide sequences and 48 to 100% homology with the deduced amino acid sequences. The hamster IFN-γ, compared with the mouse and rat homologs, had an additional 17 amino acids at the C terminus that could decrease the biological activity of this molecule and thus contribute to the extreme susceptibility of this animal to intracellular pathogens. The splenic expression of these genes in response to infection with L. donovani , the cause of visceral leishmaniasis (VL), was determined by Northern blotting. VL in the hamster is a progressive, lethal disease which very closely mimics active human disease. In this model there was pronounced expression of the Th1 cytokine mRNAs, with transcripts being detected as early as 1 week postinfection. Basal expression of IL-4 in uninfected hamsters was prominent but did not increase in response to infection with L. donovani . IL-12 transcript expression was detected at low levels in infected animals and paralleled the expression of IFN-γ. Expression of IL-10, a potent macrophage deactivator, increased throughout the course of infection and could contribute to the progressive nature of this infection. These initial studies are the first to examine the molecular immunopathogenesis of a hamster model of VL infection and indicate that progressive disease in this model of VL is not associated with early polarization of the splenic cellular immune response toward a Th2 phenotype and away from a Th1 phenotype.

An outbreak of group C rotavirus gastroenteritis among adults living in Valentim Gentil, São Paulo State, Brazil. (1998)

An outbreak of gastroenteritis affecting adults and children occurred in the small city of Valentim Gentil, São Paulo, Brazil, in 1993. Nineteen faecal samples (from 10 cases and 9 contracts) were examined by direct electron microscopy (DEM), immune electron microscopy (IEM), polyacrylamide gel electrophoresis (PAGE), and enzyme-linked immunosorbent assay (ELISA) for group A and C rotaviruses. DEM detected rotavirus in 6 of the 10 cases and in none of the contacts. All of the samples were negative for group A rotavirus by ELISA. Analysis by PAGE showed an electrophoretic profile suggestive of group C rotavirus in two cases. Group C rotavirus was identified by IEM in 4 of the cases and in 1 of the contacts. All of the samples were submitted to ELISA for group C rotavirus. This resulted in a total of 10 positives-7 for diarrhoeal cases and 3 for contacts. This outbreak was strongly associated with group C rotavirus. The importance of combining different diagnostic methods is emphasised.
Expression of the Lassa Virus Nucleocapsid Protein in Insect Cells Infected With a Recombinant Baculovirus: Application to Diagnostic Assays for Lassa Virus Infection (1990)

The coding region of the gene for the nucleocapsid protein of Lassa virus has been inserted into the genome of Autographa californica nuclear polyhedrosis virus (AcNPV) using the transfer vector pAcYM1, so that expression of the foreign DNA is under the control of the promoter of the AcNPV polyhedrin gene. Infection of cultured Spodoptera frugiperda cells with recombinant virus resulted in the synthesis of high levels of a protein that was indistinguishable from the authentic Lassa virus protein by SDS gel electrophoresis and immunoblotting with a variety of specific immune sera and monoclonal antibodies (MAbs). The kinetics of appearance of the protein were comparable to those of polyhedrin production in wild-type AcNPV-infected cells. The recombinant material was antigenic when used in ELISA for Lassa virus-specific antibodies, reacting well with MAbs specific for the nucleocapsid protein and with sera from experimentally infected guinea-pigs. The recombinant ELISA was able to clearly distinguish sera from human cases of Lassa fever against a panel of known negative sera of African origin. Recombinant-infected insect cells were an effective substitute for mammalian cells infected with Lassa virus itself in the immunofluorescence assay for Lassa virus-specific antibodies. This system offers attractive alternatives to the use of Lassa virus-infected materials as reagents in diagnostic procedures.
Inhibition of [ <sup>14</sup> C]Chloramphenicol Binding to <i>Escherichia coli</i> Ribosomes by Erythromycin Derivatives (1974)

The effect of erythromycin A and 35 analogues of erythromycin A on [(14)C]chloramphenicol binding to Escherichia coli ribosomes was evaluated. Substitutions on various portions of the erythromycin molecule were made with retention of ability to bind to ribosomes. Specifically, substantial activity in interference with [(14)C]chloramphenicol binding was retained upon removal of the cladinose and various substitutions on the 3-hydroxyl, the oxime, and 2-hydroxyl groups. Erythromycin analogues with relatively poor binding activity to ribosomes could be detected. This assay can be used alone or in conjunction with microbiological assays for screening of active analogues. It permits an estimate of the general binding activity of compounds rapidly and directly. The assay reflects the ability of the compounds to interact with their target organelle, the ribosome, and may serve as a useful adjunct in developing new compounds.
Physicochemical, Nutritional, and Sensory Qualities of Wine Grape Pomace Fortified Baked Goods (2014)

Wine grape pomace (WGP) as a source of antioxidant dietary fiber (DF) was used to fortify baked goods, including breads, muffins, and brownies. Pinot Noir WGP (RWGP) and Pinot Grigio WGP (WWGP) substituted wheat flour at concentration of 5%, 10%, and 15% for bread, 10%, 15%, 20%, and 25% RWGP for brownies, and 5%, 10%, and 15% RWGP or 10%, 15%, and 20% WWGP for muffins. The finished products were evaluated for total phenolic content (TPC), radical scavenging activity (RSA), and total DF, as well as physicochemical and sensory properties. WGP flour blends were also tested for solvent retention capacity (SRC). The highest TPC and RSA values for bread and muffins were achieved in 15% RWGP fortified samples with TPC and RSA values of 68.32 mg gallic acid equivalent (GAE)/serving and 80.70 AAE mg/serving, respectively for bread, and 2164 mg GAE/serving and 1526 mg AAE/serving, respectively for muffins. Brownies fortified with 10% RWGP had the highest RSA value (115.52 mg AAE/serving) while the control had the highest TPC value (1152 mg GAE/serving). Breads and muffins with 15% RWGP and brownies with 25% RWGP had the highest amount of DF (6.33, 12.32, and 7.73 g/serving, respectively). Sensory evaluation concluded that there is no difference in overall liking of 5% and 10% RWGP breads and muffins or 15% and 20% WGP brownies compared to the controls. This study demonstrated that WGP is a viable functional ingredient in bakery goods to increase TPC, RSA, and DF in consumer's diets.

Zirconium phosphate supported tungsten oxide solid acid catalysts for the esterification of palmitic acid (2006)

A series of zirconium phosphate supported WOx solid acid catalysts with W loadings from 1–25 wt% have been prepared on high surface area zirconium phosphate by a surface grafting method. Catalysts were characterized by N2 adsorption, FTIR, Raman, UV-Vis, 31P MAS NMR, pyridine TPD and X-ray methods. Spectroscopic measurements suggest a Keggin-type structure forms on the surface of zirconium phosphate as a (ZrOH2+)(ZrPW11O405−) species. All catalysts show high activity in palmitic acid esterification with methanol. These materials can be readily separated from the reaction system for re-use, and are resistant to leaching of the active heteropolyacid, suggesting potential industrial applications in biodiesel synthesis.
Direction finding using spatial smoothing with interpolated arrays (1992)

The problem of estimating the directions of arrival (DOAs) of signals, some of which may be perfectly correlated, is considered. A computationally efficient estimation algorithm which combines the ideas of spatial smoothing and array interpolation is derived. In one of its forms the proposed algorithm uses the root-MUSIC (root multiple signal classification) technique to compute the DOA estimates, thus avoiding the search procedure associated with the conventional MUSIC algorithm. The proposed technique can be applied to arbitrary array geometries and a general signal covariance matrix. The performance of the algorithm was evaluated by extensive simulations, and compared with the Cramer-Rao lower bound for the DOA estimates.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optical Character Recognition for Self-Service Banking (1995)

Self-service automatic teller machines (ATMs) have dramatically altered the ways in which customers interact with banks. ATMs provide the convenience of completing some banking transactions remotely and at any time. AT&T Global Information Solutions (GIS) is the world's leading provider of ATMs. These machines support such familiar services as cash withdrawals and balance inquiries. Further technological development has extended the utility and convenience of ATMs produced by GIS by facilitating check cashing and depositing, as well as direct bill payment, using an on-line system. These enhanced services, discussed in this paper, are made possible primarily through sophisticated optical character recognition (OCR) technology. Developed by an AT&T team that included GIS, AT&T Bell Laboratories Quality, Engineering, Software, and Technologies (QUEST), and AT&T Bell Laboratories Research, OCR technology was crucial to the development of these advanced ATMs.
Diazepam binding inhibitor is a potent cholecystokinin-releasing peptide in the intestine. (1996)

Pancreatic proteases in the duodenum inhibit the release of cholecystokinin (CCK) and thus exert feedback control of pancreatic exocrine secretion. Exclusion of proteases from the duodenum either by the diversion of bile-pancreatic juice or by the addition of protease inhibitors stimulates exocrine pancreatic secretion. The mechanism by which pancreatic proteases in the duodenum regulate CCK secretion is unknown. In this study, we isolated a trypsin-sensitive peptide that is secreted intraduodenally, releases CCK, and stimulates pancreatic enzyme secretion in rats. This peptide was found to be identical to the porcine diazepam binding inhibitor by peptide sequencing and mass spectrometry analysis. Intraduodenal infusion of 200 ng of synthetic porcine diazepam binding inhibitor1-86 in rats significantly stimulated pancreatic amylase output. Infusion of the CCK antagonist MK-329 completely blocked the diazepam binding inhibitor-stimulated amylase secretion. Similarly, diazepam binding inhibitor33-52 [corrected] also stimulated CCK release and pancreatic secretion in a dose-dependent manner although it was 100 times less potent than the whole peptide. Using a perfusion system containing isolated mucosal cells from the proximal intestine of rats, porcine diazepam binding inhibitor 10(-12) M) dose dependently stimulated CCK secretion. In separate studies, it was demonstrated that luminal secretion of the diazepam binding inhibitor immunoreactivity (7.5 X 10(11) M) could be detected in rat's intestinal washing following the diversion of bile-pancreatic juice. The secretion of this peptide was inhibited by atropine. In conclusion, we have isolated and characterized a CCK-releasing peptide that has a sequence identical to the porcine diazepam binding inhibitor from pig intestinal mucosa and that stimulates CCK release when administered intraduodenally in rat. This peptide may mediate feedback regulation of pancreatic enzyme secretion.
Determination of chromium by atomic absorption spectrophotometry with extraction of bromide-MIBK (1973)

原子吸光分析法によるクロム定量を臭化物抽出を併用して検討した.その結果クロム(VI)は0.5M臭化カリウム,2N硫酸溶液よりメチルイソブチルケトン(MIBK)に90%以上抽出されることを見いだした.またこのときの感度は0.05μg/ml/1%となり,水溶液に比べ約8倍の感度増大となった.抽出における共存元素については鉄はピロリン酸ナトリウムを用いることにより500ppmまでは影響がなく,マンガン,亜鉛,アルミニウム,マグネシウムについては1000ppm以上でも影響はなかった.しかし銅,コバルトは500ppm,ニッケルは250ppmまでは影響がみられないが,それ以上になると影響がみられた.確立した方法によりアルミニウム合金中の微量クロム(0.001～0.20%)を定量しほぼ満足する結果が得られた.

Using the Liberty Alliance Architecture to Secure IP-level Handovers (2006)

This paper presents a novel authentication and authorization architecture for mobile terminals while performing an IP-level handover. The proposed architecture is based on the liberty alliance single sign-on architectural framework. Using the foundation provided by this architecture, we also present a protocol to enable these security functions during the handover process. Later, we present the results of a performance comparison of the proposed protocol against the current specified mechanism for 3 GPP2-WLAN interworking. We then perform a detailed threat analysis to show that the proposed solution is secure. The solution proposed in this paper is a scalable practical solution to authenticate and authorize handovers in future generation mobile networks, leveraging on the liberty alliance architecture that operator may have deployed for authenticating service requests within a Liberty Federation
Les élastases (2001)

Les élastases sont des protéases capables de solubiliser l’élastine fibreuse. Elles peuvent faire partie de la classe des sérine protéases, des cystéine protéases ou des métalloprotéases. Les élastases de mammifères se rencontrent principalement dans le pancréas et les phagocytes. Parmi les élastases de non-mammifères, on note une grande diversité de métalloélastases et de sérine élastases bactériennes. L’activité élastolytique varie fortement d’une élastase à l’autre et n’est, en général, pas corrélée au pouvoir catalytique de ces protéases. On peut mesurer cette activité avec de l’élastine native ou marquée. Avec des élastases pures, on peut utiliser des substrats synthétiques spécifiques. Il existe un grand nombre d’inhibiteurs naturels (protéiques) et synthétiques des élastases. Les élastases peuvent jouer un rôle pathologique dans l’emphysème pulmonaire, la mucoviscidose, l’infection, l’inflammation et l’athérosclérose.
A face to face communication using real-time media conversion system (2002)

User friendly human interfaces have received great attention recently. Our goal is to realize a natural human-machine communication environment by giving a face to the computer terminal or communication system. In order to construct such an interface, a real synthesised image in real-time is needed. In this paper, we develop a real-time media conversion system and examine the communication between the user and a virtual agent with a human face on the computer monitor.
