An energy efficient priority based wireless multimedia sensor node dynamic scheduler (2015)

Wireless multimedia sensor networks have captured the attention of many due to their portability and their easy access in hard-to-access areas. They consist of a group of sensor nodes with their own transceiver and power source. The optimal connection and structure of these components allows the wireless multimedia sensor network to effectively measure and sense the physical characteristics of the environment in which they are being deployed. Their applications may vary from video surveillance, real-time traffic control systems, military applications and advanced health care delivery and other medical applications. Power, energy, frequency and voltage are the significant parameters for the Wireless Multimedia Sensors Networks. The main idea of this paper is to propose a node-level optimal Real-Time priority based Dynamic scheduling algorithm that schedules tasks according to their priorities by increasing or decreasing the frequency, using dynamic voltage frequency scaling and hence makes efficient use of energy. The Priority based scheduling helps in achieving Quality of Service (QoS) for delay sensitive traffic.
Algorithms and Implementation of Wide Area Differential GPS (1992)

The Global Positioning System (GPS) has proven to
be an extremely accurate positioning sensor for a wide
variety of applications. However, in some situations such
as aircraft precision approaches, even higher aa-zracy is
required.
Conventional Differential GPS (DGPS) usually has
accuracies of 2 to 5 meters within 100 kilometers of the
stationary calibration receiver, even with the expected
levels of induced Selective Availability (SA) errors. If
DGPS is implemented on a large scale, the total number
of local monitor stations needed to cover the United
States Continent under the same accuracy would exceed
500. Wide Area Differential GPS (WADGPS) is a
system which can reduce the number of local monitor
stations substantially and also meet such an accuracy.
The WADGPS system calculates and transmits a vector
of error corrections to the users via satellite. This
correction vector consists of parameters describing the
three dimensional ephemeris errors, and satellite clock
offsets including SA.
Field test results using 5 monitor stations showed a
couple of meters positioning accuracy and have strongly
indicated the potential of WADGPS. The
implementation and the field test performance of
WADGPS using IERS 91 campaign data, are described
in this paper. Also different algorithms for WADGPS
are discussed.
On the accommodation of coolant flow paths in high density packaging (1990)

An analytical study was conducted to determine a balance between the switching speed of logic gates and the average wiring distance in the system on the basis of the heat removal capability of the coolant. One of the models consists of a row of gate-carrying cards flanked by side boards having networks to complete three-dimensional wiring. The gates are cooled by forced convection of FC-77 or water. It is shown that the wiring distance is seriously increased by the need to make room for coolant channels within the system. As a model of a single-card system, a square array of logic gates cooled by impinging liquid jets is considered. It is concluded that the space requirement of coolant flows could set the upper bound for the density of logic gate packing. It is pointed out that more heat transfer data are needed to complete a tradeoff study.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On the Stylistic Characteristics of James Legge's Translation of Lun Yu SUR LES CARACTÉRISTIQUES STYLISTIQUES DE LA TRADUCTION DE LUN YU DE JAMES LEGGE (2010)

Closeness in style has always been the highest standard or the supreme goal of translation. A successful translation of Lun Yu is inseparable from the preservation of its original style. This paper examines whether James Legge's translation of Lun Yu reproduced the original style from the linguistic point of view and the literary point of view respectively. A careful comparative study on the source text and the target text reveals that the stylistic features of Lun Yu have been preserved in Legge's version in a considerable degree. This pioneer, and at the same time standard translation by Legge has provided us with so many good and useful translation techniques as well as enlightenment that it will continue to benefit the
A Time-Based Receiver With 2-Tap Decision Feedback Equalizer for Single-Ended Mobile DRAM Interface (2017)

A time-based (TB) receiver (RX) with a 2-tap TB decision feedback equalizer (DFE) is proposed for mobile DRAM interface. The TB RX consists of a voltage-to-time converter (VTC), a TB DFE, and a time comparator. The VTC converts the RX input voltage to a time difference between two VTC outputs by using the difference in clock-to-Q delays between two latches with different input offset voltages. The TB DFE inserts an additional delay to one of the two VTC outputs and bypasses the other VTC output to increase the time opening. The time comparator makes a decision with the first arriving edge of the two outputs of the TB DFE. While the feedback loop delay must be less than 1 UI for proper operation in the conventional voltage-based DFE, the TB DFE allows the feedback loop delay up to 1.43 UI in this paper. A transmitter (TX) transmits a single-ended signal of 200-mV swing by using an n-over-n voltage-mode driver. The transceiver in a 65-nm CMOS process achieves a 12.5 Gb/s with a 0.8-V supply through a 15-inch FR-4 channel of 14-dB loss. The TX and RX chip consume 4.3 and 3.4 mA, respectively. The energy efficiency is 0.49 pJ/b.
Rational design of arabinosyl nucleosides as antitumor and antiviral agents. (1977)

The rational design of antitumor and antiviral agents must ultimately take advantage of biochemical differences between normal host cells and transformed cells. The initial experiments must be performed with subcellular or cellular model systems. For the studies with arabinosyl nucleosides we have chosen those enzyme systems, synthesizing DNA and RNA; being precursor analogues, the different arabinosyl nucleosides have been added in the triphosphate state to the different DNA- and RNA polymerase assays. 1-beta-D-Arabinofuranosylcytosine-5'-triphosphate has been found to inhibit the RNA-dependent DNA polymerases (isolated from oncogenic RNA viruses) 200-fold more sensitively than viral and cellular DNA-dependent DNA polymerases. Recent results, showing that RNA-leukemia-virus-related sequences are present in DNA of some human leukemia patients might support the assumption that the efficacy of this antimetabolite in the treatment of acute leukemia is due to its, at least relative selective inhibitory activity on reverse transcriptase. 9-beta-D-Arabinofuranosyladenine-5'-triphosphate is a strong inhibitor of cellular DNA polymerases with the cytological consequence of an inhibition of cell proliferation. The clinical benefit of the compound in treatment of tumors is dependent on their levels of adenosine deaminase. The triphosphate of this compound is a 100-fold more sensitive inhibitor of the herpesvirus DNA polymerase compared to the cellular replicative DNA polymerase. In addition the analogue, incorporated into herpesvirus DNA, acts as chain terminator. These effects are the biochemical basis for the highly selective antiherpesvirus activity of this antimetabolite. The anomer 9-alpha-D-arabinofuranosyladenine-5'-triphosphate only inhibits cellular replicative DNA polymerase and has no effect on herpesvirus DNA polymerase. Consequently this agent acts only cytostatically and not antivirally. Concerning 1-beta-D-arabinofuranosyluracil and 1-beta-D-arabinofuranosylthymine no pronounced antitumor or antiviral effect is known.
Application Specific Logic Module Architecture For FPGAs (1992)

This paper describes an application-based enhancement of the logic module architecture for Field Programmable Gate Arrays (FPGA). Circuit speed and area of an FPGA implementation of a function is mainly affected by the complexity or functionality of its logic modules, and the structure of programmable interconnect. This paper deals with the effects of logic module structure on performance and usefulness of FPGAs for DSP applications. Based on our preliminary studies, we propose a new logic module architecture suitable for thesc applications.
In vitro susceptibilities of Aeromonas hydrophila to 32 antimicrobial agents (1981)

Minimal inhibitory concentrations of 32 antimicrobial agents for 20 strains fo Aeromonas hydrophila were determined by a microdilution method. Moxalactam was the most active drug tested. All strains were also susceptible to clinically achievable concentrations of mecillinam, cefamandole, cefuroxime, cefotaxime, aminoglycosides (except streptomycin), tetracycline, chloramphenicol, and trimethoprim-sulfamethoxazole.
Interleukin‐6 Enhances the Fertilizing Capacity of Human Sperm by Increasing Capacitation and Acrosome Reaction (1994)

ABSTRACT: The effects of human recombinant interleukin‐6 (IL‐6) on human sperm penetration of zona‐free hamster ova (SPA) and human sperm cell capacitation and acrosome reaction were investigated. IL‐6 at higher concentrations (60–600 pg/100 μl) significantly ( P < 0.001) increased rather than decreased the human sperm penetration rates in SPA. The effects were specific because immunoadsorption with the specific neutralizing antibody completely abolished the enhancing effects of IL‐6. At the same concentrations, IL‐6 also significantly enhanced spontaneous as well as calcium ionophoreinduced acrosome reaction and release of acrosin from the human sperm cells. There was no effect of IL‐6 on percent sperm motility, although it significantly affected various motility characteristics such as velocity, linearity, amplitude of lateral head displacement (ALH), and beat frequency of sperm cells—the motility parameters involved in hyperactivation phenomenon of sperm cells. These results demonstrate for the first time that IL‐6 provides a positive signal in enhancing fertilizing capacity of human sperm by increasing capacitation leading to acrosome reaction, and thus it may have clinical applications in the treatment of male infertility in humans.
A genome-wide genetic screen for host factors required for hepatitis C virus propagation (2009)

Hepatitis C virus (HCV) infection is a major cause of end-stage liver disease and a leading indication for liver transplantation. Current therapy fails in many instances and is associated with significant side effects. HCV encodes only a few proteins and depends heavily on host factors for propagation. Each of these host dependencies is a potential therapeutic target. To find host factors required by HCV, we completed a genome-wide small interfering RNA (siRNA) screen using an infectious HCV cell culture system. We applied a two-part screening protocol to allow identification of host factors involved in the complete viral lifecycle. The candidate genes found included known or previously identified factors, and also implicate many additional host cell proteins in HCV infection. To create a more comprehensive view of HCV and host cell interactions, we performed a bioinformatic meta-analysis that integrates our data with those of previous functional and proteomic studies. The identification of host factors participating in the complete HCV lifecycle will both advance our understanding of HCV pathogenesis and illuminate therapeutic targets.
Template Syntheses (1994)

Abstract Although the principle of template synthesis has been known since the sixties, surprising discoveries and new applications in the field of supramolecular chemistry over the last decade have provoked a boom in the subject. The synthesis of supramolecular species has been made much more efficient, or even in some cases possible, by the introduction of template ions or molecules. It is not just metal ions that can act as templates. Neutral molecules, electrostatic interactions, and hydrogen bonds also support the formation of binary and tertiary complexes. Energetically favorable conformations then lead to the formation of a specific desired product in high yield. In addition to the discussion of metal ions and neutral molecules as templates, covalent, positive, and negative templates are differentiated. Kinetic and thermodynamic aspects will also be considered in this review, together with the influence of templates on the phenomenon of self‐organization. Further developments and applications include the synthesis of oligonucleotides, peptide blocks capable of forming secondary structure, and template polymers. Template synthesis of defined molecular cavities ultimately leads to “inclusion chemistry on a nanometer scale.”
Multi-Antenna Fading Channel Prediction Empowered by Artificial Intelligence (2018)

Outdated channel state information (CSI) has a severe impact on a wide variety of wireless techniques. Making use of artificial intelligence, a multi-antenna channel predictor is proposed in this paper. It can accurately forecast the future CSIs up to tens of symbols ahead in a fast fading channel. By tuning the number of neurons in the input and output layers of neural network (NN) in terms of the number of antennas, it congenitally suits a multi-antenna system. Relying on a NN with real-valued weights, this predictor is simpler but substantially outperforms existing complex-valued NN predictors.

Segmented dual-gate MESFETs for variable gain and power amplifiers in GaAs MMIC (1988)

The design and performance of C-, X-, and Ku-band GaAs MMIC variable-gain and variable-power amplifier circuits using an improved segmented dual-gate MESFET device with binary scaled gate width ratios are reported. The demonstrated 35-dB control range, flat octave band gain response, and small incidental phase variation are significantly superior to the reported characteristics of conventional analog controlled devices. The design provides precise amplitude quantization while minimizing phase variations, and thus calibration complexity, incurred by gain switching.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nucleoside, XIV. Zur Synthese des 4‐Amino‐7‐oxo‐7,8‐dihydropteridin‐<i>N</i>‐8‐β‐<scp>D</scp>‐ribofuranosids — ein strukturanaloges Nucleosid des Adenosins (1974)

Abstract Zur Darstellung verschieden substituierter 2‐ und 4‐Amino‐7‐oxo‐7,8‐dihydropteridin‐ N ‐8‐β‐ D ‐ribofuranoside wird eine neue Variante der „Silyl‐Methode”︁ beschrieben, die in der Lewis‐Säure katalysierten Schmelzkondensation von 7‐(Trimethylsiloxy)pteridinen 11 – 18 mit 1‐ O ‐Acetyl‐2,3,5‐tri‐ O ‐benzoyl‐β‐ D ‐ribofuranose ( 20 ) besteht.

An Inductively Coupled Series Tube D. C. High Voltage Regulator (1948)

A new d. c. high voltage stabilizer, operating in the range from +5 to +50 kilovolts and for currents up to 50 milliamperes, is described. The stabilizer is of the usual degenerative type; but the series regulator tube, which is at high voltage, is inductively coupled to the feed-back amplifier at ground-potential. The signal from the amplifier amplitude-modulates an r-f oscillator, the output voltage of which is passed through a transformer, rectified, filtered, and applied as a d. c. correcting signal to the series tube grid. Insulation between high and low voltage circuits is provided in the r-f transformer. As an example of the short-term stabilizing action, a level of +35 kilovolts can be maintained to within 2 volts, for ±5 percent change in the input voltage, independently of load up to 50 milliamperes. The output ripple at this voltage and 20-milliamperes load is 0.05-volts r.m.s. Long-term stabilization, which depends chiefly upon constancy of the reference level, has not been measured, but means to its attainment are suggested.
MEASUREMENT OF RATES OF PHAGOCYTOSIS (1969)

A method has been developed for measuring the rate of phagocytosis rather than the quantity of particles ingested per cell when the process is virtually complete. The method, which is simpler and more rapid than those described previously, utilizes cellular monolayers, radioactive particles, and short incubation times. Under the conditions described, the rate of uptake of particles by either guinea-pig peritoneal or human blood leukocytes was proportional to both cell concentration and the time of incubation, and was independent of changes in the concentration of particles during the measurement. The particles were retained by the cells for at least 90 min. The most suitable particles so far used have been (32)P-labeled Salmonella typhimurium, and acetyl-(14)C- or methyl-(14)C-labeled starch particles. The oxidation of (14)C-labeled glucose has been studied under the same conditions that were used for the assays of phagocytosis: the greatest increase in formation of (14)CO(2) from glucose-1-(14)C occurred a few minutes after the most rapid period of phagocytosis.
Genetic Organization of the <i>Vibrio harveyi dnaA</i> Gene Region and Analysis of the Function of the <i>V. harveyi</i> DnaA Protein in <i>Escherichia coli</i> (2002)

The Vibrionaceae family is distantly related to Enterobacteriaceae within the group of bacteria possessing the Dam methylase system. We have cloned, sequenced, and analyzed the dnaA gene region of Vibrio harveyi and found that although the organization of the V. harveyi dnaA region differs from that of Escherichia coli, the expression of both genes is autoregulated and ATP-DnaA binds cooperatively to ATP-DnaA boxes in the dnaA promoter region. The DnaA proteins of V. harveyi and E. coli are interchangeable and function nearly identically in controlling dnaA transcription and the initiation of chromosomal DNA replication despite the evolutionary distance between these bacteria.
PC-PE Hollow-Fiber Membrane (1986)

Polyether-polycarbonate hollow fibers, spun by the phase inversion method, yield a dialysis membrane with a limited ultrafiltration coefficient but high diffusive permeability. Dialysers are made out of this membrane and are sterilized by gamma radiation. The dialysers show controlled ultrafiltration and clearance values for smaller molecular weight substances in the range of cellulosic membranes, but for larger molecular weight substances the clearances are higher. Correlation for ultrafiltration and clearance values, measured in saline and whole blood, indicate low interactions between blood and membrane.
Transcription factors as activators of gene transcription: AP-1 and NF-kappa B. (1997)

Cells respond to a range of cytokines and other inflammatory stimuli by selectively expressing a wide range of genes. These proinflammatory signals bind to receptors and initiate intracellular signalling cascades. This results in the activation of proinflammatory deoxyribonucleic acid (DNA)-binding proteins or transcription factors such as activator protein-1 (AP-1) or nuclear factor-kappa B (NF-kappa B). Following activation, these factors bind to specific recognition sequences in the control regions (promoters) of target genes causing modulation of gene transcription. Furthermore, numerous sites for regulation of cytokine and cytokine receptor genes by these transcription factors are found in their promoter regions. Many factors affect the formation and activity of AP-1 dimers (Fos and Jun heterodimers) through protein specific interactions or by the modulation of pre-existing complexes by phosphorylation. These complexes can vary markedly in their ability to stimulate gene transcription. Thus, induction of AP-1 activity is regulated by stimuli that either induce the de novo synthesis of AP-1 subunits or increase the activity of previously formed AP-1 dimers. NF-kappa B is activated by a number of agents including tumour necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), lipopolysaccharide (LPS) and viruses. NF-kappa B plays a central role in a range of immunological responses due to its ability to switch on inflammatory genes which lead to further activation of NF-kappa B is a heterodimer of proteins which vary in their ability to bind to DNA and/or to activate gene transcription. NF-kappa B activation is primarily regulated by sequestration of heterodimers within the cytoplasm as inactive complexes with inhibitory molecules (inhibitory-kappa B (I-kappa B)). Treatment of cells with inducing agents results in the phosphorylation of the I-kappa B molecule which is targeted for rapid degradation. This causes a rapid dissociation of the cytoplasmic NF-kappa B/I-kappa B complexes and allows translocation of the active NF-kappa B to the nucleus. Cross-coupling between NF-kappa B and AP-1 has been described which results in a synergistic increase in activity at both AP-1 and NF-kappa B sites. Elevation of both AP-1 and NF-kappa B, as reported in asthma, may therefore lead to far greater inflammation than would be present if either transcription factor alone were activated.
Listening: An Introduction to the Perception of Auditory Events (1990)

Listening combines broad coverage of acoustics, speech and music perception psychophysics, and auditory physiology with a coherent theoretical orientation in a lively and accessible introduction to the perception of music and speech events.Handel treats the production and perception of music and speech in parallel throughout the text, arguing that their production and perception follows identical principles; music and speech share the same formal properties, involve the same cognitive mechanisms, and cannot exist in separate modules. The way that a sound is produced determines the physical properties of the acoustic wave. These properties in turn lead to the perception of the event.The initial chapters take up physical processes, including a section on characterization of sound and discussion of the way instruments and speech produce musical sound. Handel explains how the environment affects perceived sounds, including reflection, reverberation, diffraction, and the Doppler effect. Subsequent chapters take up psychological processes: partitioning smeared sounds into discrete events, identifying sound sources, the units and phrases of speech and music, and speech and music rhythms. The final chapter provides a detailed treatment of the physiology and neurophysiology of the auditory system.All of the author's explanations are coherent and clear, and this strategy includes discussing particular pieces of research in detail rather than covering many things superficially Handel analyzes causes as well as describing phenomena and sets out for the reader the difficulties inherent in the research methods he discusses. He defines the physical, musical, and psychological terms used, even the most basic ones, and covers all of the experimental methods and statistical procedures in the text.Stephen Handel is Professor of Psychology at the University of Tennessee.
