802.6 MAN based personal communications network over CATV plants (1996)

An infrastructure shared 802.6 MAN based personal communication network(PCN) is to be discussed. Considering the network configurations of CATV and 802.6 MAN based PCNs, a possible architecture is proposed. It is shown that the unidirectional dual buses can be implemented over star topological CATV distribution cable networks with only two cores. The design considerations related to the network capacity and the signaling loads for wireless personal communications are investigated with numerical example. The MAN partitioning is considered to extend the capacity of the network. An analytical method to evaluate the signaling loads of 802.6 MAN based PCNs is presented with a new mobility model. It is shown that the signaling traffic increased by partitioning is not the critical constraint for the feasibility of 802.6 MAN based PCN.
Problem management and determination in SNA sub-networks (2002)

A network management architecture called the systems network architecture (SNA) is discussed. SNA contains functions that allow monitoring and control in a physical unit at the network layers. The network management category that is discussed is subnetwork problem management. The subnetwork consists of data communication equipment (DCE), data terminating equipment (DTE), and the transmission medium. Two management tools, network problem determination application (NPDA) and link problem determination aids (LPDA), used in subnetwork problem management determination are discussed. Network problem determination aids contribute to the SNA subnetwork by providing functions that were not available in other communication network management (CNM) products.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Imaging properties of annular lenses (1979)

An improvement in resolution in a conventional microscope has been shown to result if an annular condenser is employed. Here Fourier imaging in the presence of defocus and special aberration is considered, and the image of a straight-edge calculated. Imaging in confocal microscopes is superior to that in conventional microscopes and may be further improved by the use of one lens with annular aperture. Again Fourier imaging with defocus and spherical aberration is considered, resulting in an imaginary part being introduced into the transfer function. The straight edge response is very sharp.
A study of dynamic load balancing in a distributed system (1986)

This paper presents a study of a distributed system consisting of a number of hosts connected by a local area network. The system model is based on the LOCUS distributed file system. The LOCUS file system allows replicated files, and the synchronization policy is enforced by the use of the Centralized Synchronization Sites (CSS). All requests to open a file for access must be sent to the file's CSS which checks for access conflicts. Our simulation model allows process migration. The focus of this study is on load balancing as applied to optimal process and read site placement. An algorithm is proposed that increases system performance through load balancing. This algorithm uses data collected by the system on which to base its decisions. The characteristics of the algorithm and their effects on system performance are analyzed and discussed.

Repenser l’aménagement du territoire après la pandémie Covid-19 (2021)

Pendant plusieurs décennies, la politique française d’aménagement du territoire s’est montrée favorable aux villes les plus peuplées au point qu’une loi (de 2014) s’est intitulée comme devant assurer « l’affirmation des métropoles ». Précédemment, en 2010, une autre loi a surtout souhaité privilégier Paris, avec le très important projet d’une nouvelle infrastructure de transport, le métro du Grand Paris Express (GPE), accompagnée de projets d’urbanisme. Or ce projet, le plus important en Europe, suscite de nombreuses questions : correspond-il aux besoins prioritaires des Franciliens ? Est-il soutenable financièrement ? Son équation démographique peut-elle être aisément résolue ? Les paradigmes conduisant à ce projet sont-ils fondés ? Enfin, après la pandémie Covid-19, le GPE est-il plus justifié que jamais ou fait-il fausse route en termes d’aménagement du territoire ?
Serine protease inhibitors suppress pancreatic endogenous proteases and modulate bacterial neutral proteases (2010)

Pefabloc, Trasylol and Urinary Trypsin Inhibitor (UTI) have been reported to be effective serine protease inhibitors that impair pancreatic endogenous proteases resulting in improved islet yield. Here we evaluated the effect of these inhibitors on endogenous proteases (trypsin, chymotrypsin and elastase), bacterial neutral proteases (thermolysin and neutral protease) and islet isolation digestion samples. Protease activity was measured using a fluorimetric assay and islet function was assessed by dynamic perifusion. Trypsin, chymotrypsin and elastase were significantly inhibited by Pefabloc and UTI. Trasylol showed strong inhibitory effects on trypsin and chymotrypsin but also decreased thermolysin activity. UTI was found to inhibit the activity of endogenous proteases and increase the activity of bacterial neutral proteases. Human islets exposed to Pefabloc had reduced insulin response, unlike Trasylol or UTI, which had no detrimental effect on insulin secretion. Although Trasylol was an effective inhibitor of endogenous proteases, FDA regulatory issues preclude its use in clinical application and thus in the isolation process. UTI has the greatest potential because it impairs endogenous pancreatic proteases and enhances digestion enzymes.
Regulation of C gamma subclass germ-line transcripts in human peripheral blood B cells. (1993)

In the present study we investigated the early steps of human IgG subclass differentiation by defining the conditions necessary for IgG subclass-specific production of germ-line transcripts in human peripheral blood B cells. Constant region of gamma-globulin (C gamma) subclass germ-line transcripts were measured using newly developed reverse transcription and polymerase chain reaction (RT-PCR) assays that were shown to be C gamma subclass-specific germ-line transcripts by size of the amplification products obtained before and after digestion with appropriate endonucleases (NarI and NcoI). In initial studies we found that C gamma 1 and C gamma 2 germ-line transcripts were constitutively expressed in total peripheral blood B cells, but not in high density sIgM+(sIgG-) B cells prepared with Percoll density gradients and magnetic beads separation techniques; the latter cells were therefore used throughout this study. Induction of germ-line transcripts (germ-line C gamma 1 transcript) was noted in stimulated B cells (SAC plus IL-2) at 6 h; thus, the appearance of germ-line transcripts could not be attributed to preferential growth of B cells expressing germ-line transcripts. In subsequent studies we found that induction of germ-line transcripts for the various IgG subclasses fell into two patterns. Induction of C gamma 3 and C gamma 1 germ-line transcripts, transcripts of genes in the first human duplication unit, generally required a proliferative stimulus (Staphylococcus aureus Cowan I, SAC) and was brought about by SAC plus IL-4 (C gamma 3 germ-line transcripts) and SAC alone or SAC plus IL-2 (C gamma 1 germ-line transcripts); in contrast, induction of C gamma 2 and C gamma 4 germ-line transcripts, transcripts of genes in the second duplication unit, was accomplished with cytokines alone: IFN-gamma (C gamma 2 germ-line transcripts) and IL-4 (C gamma 4 germ-line transcripts), and was not augmented by addition of a proliferative stimulus. Finally, we found that IFN-gamma inhibited IL-4-induced C gamma 3 and C gamma 4 germ-line transcripts (with or without SAC). These findings establish that the various human IgG subclasses manifest distinct requirements for the regulation of early steps in isotype differentiation. In addition, they suggest that human C gamma genes exhibit patterns of regulation related to their respective duplication units.
Nucleophilic reactions of electrogenerated superoxide ion (1970)

Electrochemical techniques were used to show that in dipolar aprotic solvents superoxide ion is an effective nucleophile in substitution (with primary and secondary alkyl halides), elimination (with tertiary and 2-aryl ethyl halides), and addition (to activated double bonds). Mechanisms inferred from instrumental studies were confirmed by controlled-potential electrolysis.
A pitch-synchronous digital feature extraction system for phonemic recognition of speech (1976)

The system described in this paper is subdivided into three main steps: pitch extraction, segmentation, and formant analysis. The pitch extractor uses an adaptive digital filter in time-domain transforming the speech signal into a signal similar to the glottal waveform. Using the levels of the speech signal and the differenced signal as parameters in time domain, the subsequent segmentation algorithm derives a signal parameter which describes the speed of articulatory movement. From this, the signal is divided into "stationary" and "'transitional" segments; one stationary segment is associated to one phoneme. For the formant tracking procedure, a subset of the pitch periods is selected by the segmentation algorithm and is transformed into frequency domain. The formant tracking algorithm uses a maximum detection strategy and continuity criteria for adjacent spectra. After this step, the total parameter set is offered to an adaptive universal pattern classifier which is trained by selected material before working. For stationary phonemes, the recognition rate is about 85 percent when training material and test material are uttered by the same speaker. The recognition rate is increased to about 90 percent when segmentation results are used.
Excretion of Deoxyribonucleic Acid by Lymphocytes Stimulated with Phytohemagglutinin or Antigen (1972)

When human lymphocytes are cultured in the presence of phytomitogens, 70-90% of the cells undergo blast transformation and synthesize DNA. However, less than 40% of these lymphocytes actually undergo mitosis while 35-90% of the newly synthesized DNA is excreted into the media. The release of DNA by the cells is selective since experiments with [(14)C]uridine indicate that RNA is not lost into the culture media. DNA excretion occurs under many culture conditions. The excreted DNA has an estimated molecular weight of 3 to 12 x 10(6) as determined by gel filtration on Sepharose 2B. It forms a single sharp peak at a density of 1.055 g/cm(3) when examined by sucrose density gradient centrifugation, suggesting that the DNA is complexed to protein or lipid.
Behaviour of Bifunctional and Polyfunctional Reactive Dyes Applied to Cotton Cellulose (1977)

Analytical techniques, viz. electron microscopy, surface area determination, and swelling in cadoxen solvent, have been used to obtain results which provide positive evidence for the formation of crosslinks between adjacent cellulose chains in cotton dyed with different classes of bi‐ and poly‐functional reactive dyes. Reactive dyes selected include those where either the reactive groups are present in the same nucleus (dichlorotriazinyl, monomethoxymonochlorotriazinyl, dichloroquinoxaline, trichloropyrimidinyl and difluoromonochloropyrimidinyl) or where the two reactive groups are present at different positions in the dye molecule (Procion HE (ICI) and Procion Supra (ICI)). The extent of changes observed in the morphology of cotton fibre as a result of dyeing with bi‐ and poly‐functional reactive dyes has been found to depend on the amount of dye present in the fibre and the conditions of application.
In vitro susceptibilities of five Leptospira strains to 16 antimicrobial agents (1983)

The in vitro activities of 16 antibiotics against five serovar strains of the genus Leptospira were determined. Five of the antibiotics (ampicillin, cefmetazole, moxalactam, ceftizoxime, and cefotaxime) exhibited a lower minimal inhibitory concentration than did penicillin G. In tests for minimal bactericidal concentration, ceftizoxime and cefotaxime were found to be more effective than penicillin G, streptomycin, tetracycline, ampicillin, and cefmetazole.

ECNU at SemEval-2017 Task 1: Leverage Kernel-based Traditional NLP features and Neural Networks to Build a Universal Model for Multilingual and Cross-lingual Semantic Textual Similarity (2017)

To model semantic similarity for multilingual and cross-lingual sentence pairs, we first translate foreign languages into English, and then build an efficient monolingual English system with multiple NLP features. Our system is further supported by deep learning models and our best run achieves the mean Pearson correlation 73.16% in primary track.
Digital and Analog Enhancement Techniques (1978)

Digital and analog units for enhancing video signals and images are often regarded as competing with each other. There is no point in setting them up as adversaries, but the criteria for selecting one approach over the other should be understood. Analog enhancement is to be preferred when the required signal processing is simple and straightforward and when cost is a primary constraint. Even the simplest digital enhancement systems, however, cost as much as moderately expensive analog systems, so their use is generally reserved for complicated operations, such as those requiring long delay times, where analog systems do not perform well. It is recognized that this situation is changing as analog technology develops (CCDs and diode arrays, for example) and as digital components get cheaper. Stand-alone systems will be more expensive than those included in other devices whether they are analog or digital. Finally, when all the constraints are taken into account (particularly the required performance characteristics and money available), it can be decided whether the proper approach is analog, digital or hybrid.
Expression of matrix metalloproteinases and their inhibitors in different immunohistochemical-based molecular subtypes of breast cancer (2014)

We found some variations in MMP and TIMP expression among the immunohistochemical-based molecular subtypes of breast carcinomas, suggesting differences in their tumor pathophysiology. Additional studies are needed to determine the mechanisms underlying the differences of MMP and TIMP expression in the molecular subtypes for the development of specific therapeutic targets for breast cancer subtypes.
Amino‐terminal deletions in the decorin core protein leads to the biosynthesis of proteoglycans with shorter glycosaminoglycan chains (1996)

Analysis of the N-terminal sequence of decorin purified from connective tissues and comparison with the sequence deduced from the cDNA indicate that the nascent proteoglycan has a 14 amino acid residue N-terminal propeptide. Mammalian expression vectors encoding wild-type decorin and decorin with deletions in the propeptide were used to transform COS and CHO cells. Cells transformed with vectors encoding deletion variants of decorin synthesize proteoglycans with shorter galactosaminoglycan chains than cells transformed with wild-type decorin. This effect on the polysaccharide chain length may be due to a lower affinity between the core protein and the glycosyltransferases synthesizing the linkage region. Alternatively, the deletions may affect the intracellular transport of decorin. An antiserum prepared against the N-terminal propeptide immunoprecipitated decorin secreted by cultured cells, showing that decorin is exported with the N-terminal region intact.
Physics of basketball (1981)

Does a knowledge of physics help to improve one’s basketball skills? Several applications of physical principles to the game of basketball are examined. The kinematics of a basketball shot is studied, and criteria are established for determining the best shooting angle at any given distance from the basket. It is found that there is an optimum shooting angle which requires the smallest launching force and provides the greatest margin for error. Some simple classroom illustrations of Newtonian mechanics based on basketball are also suggested.
Technology assessment for mission-critical services on automotive virtual edge communicator (AVEC) (2018)

Mission critical services are beginning to migrate to broadband from the trusted-but-limited existing systems. They need assured availability and confidentiality for communication in areas affected by a disaster, flash crowding or any catastrophic network failure. This paper describes a vision for an automotive virtual edge Communication scheme that helps healing stricken networks, utilizing any available resources for hosting network functions on vehicles. Emergency and essential service organizations who rush to the area would `bring their own network', i.e. computing capacity and connectivity tools, aboard their service vehicles. These vehicles form a dynamic community that shares resources, information and services, using the combined processing capacity via virtualized core functions. To realize such a scheme, innovative features are required, such as cooperative hosting, opportunistic vehicular resource virtualization, context-based edge SDN traffic prioritization, and ad-hoc vehicular community management, including multi-entity authentication.
Sulfur Heterocycles for Organic Conductors and Superconductors (1989)

Abstract Series of new π-donors and acceptors based on sulfur heterocycles have been prepared, and the physico-chemical properties of the neutral species as well as their charge-transfer complexes and radical salts were investigated. These new families are an isomeric series of thiophene-fused TCNQ, a homologous series of thieno-acenes, and an unsymmetrical donor family comprised of dithiadiselenafulvalene framework. The unsymmetrical donor dimethyl-(ethylenedithio)dithiadiselenafulvalene (DMET) was found to give various kinds of superconducting radical salts.
Non‐oxidative Thermal Degradation of Poly(glycidol), Poly(glycidol)‐g‐<scp>L</scp>‐lactide, and Poly(glycidol)‐g‐glycolide (2011)

Abstract Three polymers of pharmaceutical/medical relevance are synthesized: poly(glycidol) (PG), poly(glycidol)‐g‐ L ‐lactide (PG‐g‐La), and poly(glycidol)‐g‐glycolide (PG‐g‐Gly). Because the thermal stability of these polymers is an essential factor of their processing and practical application, the study focuses on kinetic and mechanistic aspects of non‐oxidative thermal degradation. The study is conducted by combining thermogravimetry, Fourier transform infrared spectroscopy, and isoconversional kinetic analysis. It is found that PG degrades in a single mass loss step, whereas, PG‐g‐La and PG‐g‐Gly in two. It is demonstrated that the first step in degradation of PG‐g‐La and PG‐g‐Gly is associated with decomposition of the pendant groups and the second is due to degradation of the PG backbone. magnified image
TLM: a trench leakage monitor for a four megabit SPT DRAM technology (1991)

The authors discuss a single trench capacitor macro-array structure used for trench dynamic random access memory (DRAM) device design and characterization, and as a manufacturing test vehicle. A nonaddressable array of trench-capacitor DRAM cells is used for quantification of trench DRAM leakage parameters, storage node parasitic device characterization, and silicon defects. Used with an addressable functional monitor, it is found to be a valuable semiconductor process development vehicle to achieve functionality and cell retention yield for a 4-Mb CMOS DRAM technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Caffeinated and Decaffeinated Coffee Consumption and Risk of Type 2 Diabetes: A Systematic Review and a Dose-Response Meta-analysis (2014)

A matched expansion probe card for high temperature LSI testing (2005)

This paper describes the fabrication process and mechanical properties of a novel probe card were described. To match the thermal expansion between the probe card and a silicon wafer in wafer-level burn-in test, a Pyrex glass substrate with feedthrough connections was used to support the probes. To make the slantwise probe contactors, spray coating was used to form a uniform photoresist film on a deeply-wet-etched silicon wafer. The fabricated probe card has 13185 p/sup +/ silicon probe contactors at a pitch of 150 /spl mu/m on an area of 44.0 mm /spl times/ 45.7 mm. The rigidity of the probes is approximately 91.45 N/m. The planarity of the probe tips is within /spl plusmn/ 1 /spl mu/m from the base level.
