Regulation of Glycine Decarboxylase and l-Serine Hydroxymethyltransferase Activities by Glyoxylate in Tobacco Leaf Mitochondrial Preparations (1982)

Glyoxylate at a concentration of 10 millimolar caused 50% inhibition of decarboxylation of 20 millimolar [1-(14)C]glycine and accompanying synthesis of serine in a mitochondria-enriched preparation from tobacco (Nicotiana tabacum var. John Williams Broadleaf) leaves. None of the other compounds tested including formate, acetate, oxalate, aspartate, and glutamate appreciably affected activity. Occasional inhibition produced by glycolate may have resulted from residual glycolate oxidase in these preparations. Added glyoxylate was not converted to glycine in these preparations and about 98% of it could be recovered at the end of the reaction. Hence, the observed inhibition by glyoxylate did not result from dilution of radioactivity in the substrate.Glyoxylate also regulated synthesis of HCHO from l-serine catalyzed by l-serine hydroxymethyltransferase in mitochondrial preparations. Control of this enzyme activity by glyoxylate was complex and was characterized by enhancement of activity at low glyoxylate concentrations (less than 10 millimolar) and inhibition by concentrations generally above 10 millimolar. These results define potential sites of biochemical regulation of important steps in the pathway of photorespiratory carbon flow and are considered in the light of other observations of effects of exogenous glyoxylate on photorespiration in leaf tissue.
Enhanced infrared absorption with dielectric nanoparticles (2003)

Enhanced infrared absorption is demonstrated for anthracene coating polar dielectric nanoparticles of silicon carbide and aluminum oxide. An enhancement factor greater than 100 was measured near the surface of silicon carbide particles. This is the result of the enhanced optical fields at the surface of the particles when illuminated at the surface phonon resonance frequencies. This phonon resonance effect is analogous to plasmon resonance that is the basis of surface enhanced infrared absorption and surface enhanced Raman scattering. The results have implications for near-field microscopy, the characterization of nano-optical devices, and chemical sensing. In addition, the methodology used for surface phonon analysis of particles is useful for simulating comet and interstellar dust spectra.
Improvement of digital mapping predistorters for linearising transmitters (2002)

In this paper we present a new kind of 2-dimensional mapping predistorter for linearising transmitters. This method applies self-tuning adaptive control to eliminate iteration processes and therefore to reduce adaptation time. All errors due to modulator imperfections (e.g. RF carrier leakage from local oscillator, differential gain and phase imbalance between I and Q paths) can be corrected by this method. The simulation shows that adaptation time and memory size of look-up-tables are reduced.
Quantum magic bullets by means of entanglement (2002)

Two particles that are entangled with respect to continuous variables such as position and momentum exhibit a variety of nonclassical features. First, measurement of one particle projects the other particle into the state that is the complex conjugate of the state of the first particle; i.e., measurement of one particle projects the other particle into the time-reversed state. Second, continuous-variable entanglement can be used to implement a quantum magic bullet: When one particle manages to pass through a scattering potential, then, no matter how low the probability of this event, the second particle will also pass through a related scattering potential with probability 1. This phenomenon is investigated in terms of the original Einstein–Podolsky–Rosen state, and experimental realizations are suggested in terms of entangled photon states.

The structures, features, electrical characteristics, and successful application results of two types of high-voltage high-power reverse-conducting thyristors are described. The first has blocking voltage ratings of 1300 V and current ratings of 400 A in the forward direction and 150 A in the reverse direction, with a turn-off time of 30 μs. The second has ratings of blocking voltage of 2500 V, current ratings of 400 A in the forward direction and 150 A in the reverse direction, with a turn-off time of 40μs.
Vietnamese Noun Phrase Chunking Based on Conditional Random Fields (2009)

Noun phrase chunking is an important and useful task in many natural language processing applications. It is studied well for English, however with Vietnamese it is still an open problem. This paper presents a Vietnamese noun phrase chunking approach based on conditional random fields (CRFs) models. We also describe a method to build Vietnamese corpus from a set of hand annotated sentences. For evaluation, we perform several experiments using different feature settings. Outcome results on our corpus show a high performance with the average of recall and precision 82.72% and 82.62% respectively.
Ruptured Ectopic Pregnancy: An Emergency Physician Perspective (2018)

Early diagnosis of an ectopic pregnancy remains challenging in a medical emergency. Despite advances in diagnostic methods and management, ruptured ectopic pregnancy continues to cause 6% pregnancy related deaths, often because of failure to recognize the early signs and symptoms. The common teaching is that pregnancy should always remain in the list of clinical possibilities for abdominal pain in a woman of reproductive age. Moreover, acute abdomen in hemodynamically unstable young women with a history of one or two missed menstrual periods suggests a ruptured ectopic pregnancy. There is no substitute for a high index of clinical suspicion. Emergency physician should maintain a low threshold for diagnosing the condition, given its fatal outcomes.
ased Predictors with Robust for Transmission of uences Over Noisy C (1996)

A new image sequence coding technique based on robust median-based predictors is presented for the transmis- sion of image sequences over noisy channels. We analyze the robustness of median-based predictors against channel errors. A heuristic algorithm for the design of a robust predictor from a given median-based predictor is presented. It is shown that with small modifications in terms of a necessary requirement for a median-based predictor to be robust against channel errors, the robustness of a given median-based predictor can be considerably improved. Simulations on a real image sequence show signifi- cant improvement over the conventional differential pulse code modulation (DPCM) at high bit error rate (BER) using this new technique. The technique does not increase the transmission rate. It is shown that the quality of reconstructed images obtained by robust median-based predictors can be further improved by postprocessing the image using a nonlinear detail-preserving noise-smoothing filter.
Inheritance of Pericarp Types, Sterility, and Dwarfhess in Several Safflower Crosses1 (1966)

Investigations were conducted to further elucidate information available regarding the inheritance of pericarp and anther dehiscence characteristics of safflower. Previous reports that reduced pericarp and delayed another dehiscence are controlled by the recessive gene th and that striped seed is controlled by the recessive gene stp , which is inherited independently of th, were confirmed. An intermediate expression of pericarp thickness, where the hull was thin at the upper end only, was determined to be controlled by the same major gene th. In certain genotypic backgrounds the expression of the th gene is modified considerably with regards to pericarp development without materially affecting delayed anther dehiscence. No evidence of linkage was observed between the independent genes, th and stp , and several well known genetic markers in safflower. Since no recombination was observed between extremely thin pericarp and delayed anther dehiscence the hypothesis was proposed that these characteristics were the pleiotropic manifestations of the thin‐hull gene. It is assumed that spontaneous single‐gene mutations were responsible for the presence of sterile and dwarfed plants found in the progenies of one cross. Although the possibility of new recombinations and not mutation was not ruled out entirely, the evidence available does suggest that hybridization between certain strains of safflower may stimulate mutations.
Formation of Electromigration Defects in Small Damascene Cu Interconnects with Respect to the Microstructure (2004)

Electromigration processes in Cu metallization are of increasing importance in microelectronics. In order to study correlations between microstructural details and localization of electromigration defects generated in narrow electroplated Cu lines, microstructure of entire line was recorded by EBSD measurements with high lateral resolution, and then electromigration test was performed in high vacuum under direct SEM observation. To do this, the lines had to be unpassivated.Short electroplated Cu lines (length of 20 and 50 μm, width of 230 to 130 nm) were loaded at 250°C and 20 MA/cm2 with in‐situ‐SEM observation, and EBSD maps of the line with stepsize, i.e. point distance of 20 nm were acquired before and after test. In the result, a number of hillocks were found to have grown in the vicinity of (100) grains having at least one high angle grain boundary around it. Fatal voids often formed at the cathode end and produced dielectric cracking in some cases. Furthermore, voiding started from the sidewall of interconnect trenches mostly at such places where (111) grains with high angle grain boundaries were located. Microstructure of lines down to 130 nm was analysed with respect to electromigration defects, and the electromigration behavior was found to be rather similar compared to larger lines.

Fiber Bragg grating sensors for seismic wave detection (2005)

The work presented in this paper demonstrates a sensing technology for unattended seismic sensors based on the optical fiber Bragg grating. This kind of sensor can perform accurate measurements of the seismic activity due to their high sensitivity to dynamic strains caused by small ground vibrations. One of the applications is its deployment in the battlefield remote monitoring system to track and geo-locate the presence of personnel, wheeled vehicles, and tracked vehicles. The experimental data of the field test are shown as well as the comparable result with commercial seismic sensors.
An image database system with fast image indexing capability based on color histograms (2002)

While general object recognition is difficult, it is relatively easy to capture some inherent image properties, such as color distribution, to narrow down the search range when an attempt to retrieve images from an image database is made. We have built an image database in which images are indexed automatically using a histogram indexing method that we have proposed. With this method, a numerical index key is created for each image histogram using a set of mathematical formulas. By using this approach, we have transformed the difficult problem of image matching into one of image retrieval by index keys, which can be supported by existing database implementation techniques. We have also provided two query methods: image retrieval by user-provided sample images, and image retrieval by combinations of system-provided templates (such as sky, lawn, brick wall, and so on). Our initial experiments on the image database system have shown favorable results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Some high-pressure x-ray diffraction studies using beryllium gasketing on a diffractometer with rotating anode x-ray source (1984)

The beryllium gasketing technique is employed in a high-pressure (0–10 GPa) x-ray powder diffractometer using a NaI(T1) scintillation detector in conjunction with a high-brilliance rotating anode x-ray source. The beryllium gasket permits the use of a liquid pressure transmitting medium in the sample chamber giving rise to hydrostatic pressure conditions. This metal gasket also allows the use of softer Cu Kα radiation because of less absorption, thereby ensuring high resolution. The Be gasket is calibrated using sodium chloride and the equation of state (EOS) of strontium metal is measured up to 6 GPa using Cu Kα radiation in both the low-pressure (fcc) and high-pressure (bcc) phases. However, for high-Z samples like rare earths, Mo Kα radiation is employed to minimize absorption in the sample material. The high-pressure valence transition and the EOS of the rare earth alloy Ce0.92 La0.08 were studied up to 5.5 GPa. The γ→α transition in this cerium alloy is smeared out as compared to pure cerium metal.
The DNA SET: a novel device for single-molecule DNA sequencing (2004)

We present the principle of the dnaSET, a novel device for single-molecule sequence analysis of DNA strands. The central idea is to measure the variations in current through a single electron transistor (SET) as a target DNA molecule slithers through a nanoeye integrated between the SET's floating island and gate. We present a basic but illustrative simulation of the operation, and the results therefrom lead us to conclude that the DNA SET has a single-nucleotide resolution that enables it to read off the individual bases in a DNA strand. The versatility of this idea makes it suitable for incorporation in other bio-assay tools, and thus the DNA/protein SET promises to be a powerful direct sensing device for a wide range of applications.
Experimental observation of limit-cycle oscillations in a short-pulse free-electron laser (1993)

The first experimental observation of limit-cycle power oscillations in a short-pulse free-electron laser is presented. These are due to a nonlinear modulation of the optical micropulse shape and phase by the electrons, which leads to the formation of a train of subpulses. Experimentally, the oscillations have been found to depend on the slippage distance and on the desynchronism between optical pulses and electron bunches, comparing well with theoretical predictions.

Macromolecular Crowding and Protein Stability (2012)

An understanding of cellular chemistry requires knowledge of how crowded environments affect proteins. The influence of crowding on protein stability arises from two phenomena, hard-core repulsions and soft (i.e., chemical) interactions. Most efforts to understand crowding effects on protein stability, however, focus on hard-core repulsions, which are inherently entropic and stabilizing. We assessed these phenomena by measuring the temperature dependence of NMR-detected amide proton exchange and used these data to extract the entropic and enthalpic contributions of crowding to the stability of ubiquitin. Contrary to expectations, the contribution of chemical interactions is large and in many cases dominates the contribution from hardcore repulsions. Our results show that both chemical interactions and hard-core repulsions must be considered when assessing the effects of crowding and help explain previous observations about protein stability and dynamics in cells.
Dextromethorphan and Memantine in Painful Diabetic Neuropathy and Postherpetic Neuralgia (2002)

Dextromethorphan is effective in a dose-related fashion in selected patients with DN. This was not true of PHN, suggesting a difference in pain mechanisms. Selective approaches to pain-relevant N-methyl-d-aspartate receptors are warranted.
CENTER: Critical Thinking in Team Decision-making (2017)

This chapter discusses the initial development of the Collaborative Critical Thinking (CCT) construct and an attempt to develop training and a software tool to facilitate the use of CCT. It discusses the measures, feedback, tools and training that make it possible for decision makers to develop CCT and the validating a polling application developed to enhance CCT: the Collaboration for enhanced Team reasoning (CENTER) tool. A fundamental challenge of military organizations is to operate decisively and synchronously in highly uncertain and dynamic settings. Military organizations define roles such as scout, air surveillance operator and tactical intelligence analyst. CENTER allows a leader or facilitator to select a subset of probes appropriate to the mission at hand, and customize them or use them in their generic form. The facilitator can then trigger the delivery of each probe to networked members of the team.
Sequence variation divides Equine rhinitis B virus into three distinct phylogenetic groups that correlate with serotype and acid stability (2005)

Equine rhinitis B virus (ERBV), genus Erbovirus , family Picornaviridae , occurs as two serotypes, ERBV1 and ERBV2, and the few isolates previously tested were acid labile. Of 24 ERBV1 isolates tested in the studies reported here, 19 were acid labile and five were acid stable. The two available ERBV2 isolates, as expected, were acid labile. Nucleotide sequences of the P1 region encoding the capsid proteins VP1, VP2, VP3 and VP4 were determined for five acid-labile and three acid-stable ERBV1 isolates and one acid-labile ERBV2 isolate. The sequences were aligned with the published sequences of the prototype acid-labile ERBV1.1436/71 and the prototype ERBV2.313/75. The three acid-stable ERBV1 were closely related in a phylogenetic group that was distinct from the group of six acid-labile ERBV1, which were also closely related to each other. The two acid-labile ERBV2 formed a third distinct group. One acid-labile ERBV1 had a chimeric acid-labile/acid-stable ERBV1 P1 sequence, presumably because of a recombination event within VP2 and this was supported by SimPlot analysis. ERBV1 rabbit antiserum neutralized acid-stable and acid-labile ERBV1 isolates similarly. Accordingly, three distinct phylogenetic groups of erboviruses exist that are consistent with serotype and acid stability phenotypes.
<title>Tools for robust image and video coding in JPEG-2000 and MPEG-4 standards</title> (1998)

In this paper, we review the tools for error resilient image and video coding that have already been incorporated in the upcoming ISO/IEC MPEG4 and JPEG2000 video and image coding standards. We also review the ongoing work that are being currently conducted at the evolving JPEG2000 standard. The methodology adopted by the MPEG and JPEG standards bodies for developing error resilience tools is also discussed. Finally, we provide performance data on the effectiveness of these error resilience tools under various channel conditions.

Cysteine mutants of herpes simplex virus type 1 glycoprotein D exhibit temperature-sensitive properties in structure and function (1990)

We previously constructed seven mutations in the gene for glycoprotein D (gD) of herpes simplex virus type 1 in which the codon for one of the cysteine residues was replaced by a serine codon. Each of the mutant genes was cloned into a eucaryotic expression vector, and the proteins were transiently expressed in mammalian cells. We found that alteration of any of the first six cysteine residues had profound effects on protein conformation and oligosaccharide processing. In this report, we show that five of the mutant proteins exhibit temperature-sensitive differences in such properties as aggregation, antigenic conformation, oligosaccharide processing, and transport to the cell surface. Using a complementation assay, we have now assessed the ability of the mutant proteins to function in virus infection. This assay tests the ability of the mutant proteins expressed from transfected plasmids to rescue production of infectious virions of a gD-minus virus, F-gD beta, in Vero cells. Two mutant proteins, Cys-2 (Cys-106 to Ser) and Cys-4 (Cys-127 to Ser), were able to complement F-gD beta at 31.5 degrees C but not at 37 degrees C. The rescued viruses, designated F-gD beta(Cys-2) and F-gD beta(Cys-4), were neutralized as efficiently as wild-type virus by anti-gD monoclonal antibodies, indicating that gD was present in the virion envelope in a functional form. Both F-gD beta(Cys-2) and F-gD beta(Cys-4) functioned normally in a penetration assay. However, the infectivity of these viruses was markedly reduced compared with that of the wild type when they were preincubated at temperatures above 37 degrees C. The results suggest that mutations involving Cys-106 or Cys-127 in gD-1 confer a temperature-sensitive phenotype on herpes simplex virus. These and other properties of the cysteine-to-serine mutants allowed us to predict a disulfide bonding pattern for gD.
