Development of the plasma channel of a plasma dipole antenna created by the radiation of a transmitter (2015)

Characteristics of the plasma layer (a plasma antenna of dipole type), excited by the radiation of a transmitter such as the carrier density distribution over the radius of the dielectric tube (near the boundary) and the growth rate of the plasma region along the tube length are considered. It is shown that it is possible to distinguish such typical dimensions as the radius of the dielectric tube, the radius of the plasma column, and the thickness of the skin layer, and, depending on relationships between these dimensions, consider the influence of the transition layer on excitation of the surface wave in the plane or cylindrical symmetry.

The effect of glucose and insulin on in vitro proliferation of Plasmodium falciparum (2011)

With increasing prevalence rates of diabetes mellitus in tropical countries, malaria and diabetes often coincide. The study was designed to investigate the effects of glucose and insulin upon in vitro proliferation of Plasmodium falciparum, the causative agent of malaria tropica. Plasmodium falciparum proliferation was determined via the Malstat™ assay, following incubation of the parasites at varying concentrations of glucose (0 - 27.7mM) or insulin (10 pM - 100µM) for 24 and 48 hrs. While Plasmodium falciparum proliferation was unaffected at concentrations of 5.5 – 27.7mM glucose, growth was impaired below a threshold of 5.5mM. No effect was seen following incubation of the parasites in the presence of 10pM – 100µM insulin. Insulin levels did not affect parasite proliferation whilst glucose levels below 5.5mM reduced parasite growth. The Malstat™ assay was identified as a suitable screening assay to assess the effects of glycemic control upon Plasmodium falciparum growth.

Squelette membranaire chez Paramecium tetraurelia : caractérisation d'une nouvelle famille multigénique et analyse par les approches GFP et RNAi (2005)

The cortex of most ciliated protozoa encloses a membrane skeleton including the epiplasm, a sub-membranous layer extending underneath the cytoplasmic face of the inner alveolar membrane. In Paramecium, epiplasmic scales are centered around ciliary units and are composed of a complex set of proteins named epiplasmins. In the first part of this study, using the sequence of two epiplasmins (EPI-1 and EPI-2), we have contributed to the annotation of Paramecium tetraurelia macronuclear genome and identified 39 additional sequences. Two orthologous sequences were found in the Tetrahymena thermophila genome. Structural analysis of the 43 sequences indicates that the hallmark of this new multigenic family is a 79 amino acids domain flanked by two Q, P and V-rich stretches of sequence that are much more variable in amino-acid composition. A phylogenetic analysis confirmed the existence of 3 sub-families (on a total of 4) that were previously determined on the basis of distinct biochemical properties. The expression of GFP-tagged epiplasmin 1 showed significant labelling of epiplasmic scales and oral structures as well. The second part concerns the functional analysis of epiplasmins using an RNA interference approach. Following the ingestion of bacteria producing double-stranded RNA homologous to the EPI-1 and/or EPI-2 coding sequences, we obtained a phenotype named "boomerang" characterized by repeated blockages of cytokinesis leading to monstrous organisms which are finally lysed after 72 hours of induction. The analysis of induced cells by fluorescence microscopy revealed multiple abnormalities in cortical morphogenesis and karyokinesis processes despite the normal progression of some mechanisms like oral apparatus duplication. Finally, the production of a novel antibody raised against 2 peptides (1 and 2) included in epiplasmins 1 and 2 sequences, and decorating the epiplasm of Paramecium, allowed us to evidence the co-suppression of a sub-family of epiplasmins following the "boomerang" phenotype induction. The epitope of the monoclonal antibody (CTS-32) which labels the overall family of epiplasmins is not contained in peptides 1 and 2.
Turbulent transport in premixed flames (1994)

Simulations of planar, premixed turbulent flames with heat release were used to study turbulent transport. Reynolds stress and Reynolds flux budgets were obtained and used to guide the investigation of important physical effects. Essentially all pressure terms in the transport equations were found to be significant. In the Reynolds flux equations, these terms are the major source of counter-gradient transport. Viscous and molecular terms were also found to be significant, with both dilatational and solenoidal terms contributing to the Reynolds stress dissipation. The BML theory of premixed turbulent combustion was critically examined in detail. The BML bimodal pdf was found to agree well with the DNS data. All BML decompositions, through the third moments, show very good agreement with the DNS results. Several BML models for conditional terms were checked using the DNS data and were found to require more extensive development.
Further Investigation for Piecewise Sampling to Overcome Transient Effect of Staircase Waveform (2017)

A further investigation of the new approach to overcome the transient effect of staircase waveform is reported. The piecewise sampling is reviewed, in which a normal sampling is performed but the discrete Fourier transform is only applied to partial samples while the other samples located on both sides of each step are discarded. The applicability of the analog-to-digital converter (ADC) with antialiasing filter is verified through comparison with another ADC without such filter. The parameter settings of the step number in one period, the number of samples at each step, and the frequency of the staircase waveform are investigated with the experimental results. An experimental approach is introduced to determine the location and length of the desired piecewise sampling. The available frequency of staircase waveform is limited by the settling time of digital-to-analog converter (DAC). For higher frequency measurements, the well-known multiperiod strategy previously applied in ADC is proposed to have its application extended into DAC. From another perspective, it will widen the width of the step and alleviate the need for frequent conversions. The relevant principles, procedures and experimental evidences are presented. The experimental results indicate that no significant additional measurement error is detected.
Techno-Economic Aspects of a Wood-to-Ethanol Process: Energy Demand and Possibilities for Integration (2007)

Full-scale ethanol production from spruce has been evaluated, mainly from an energy perspective, using an Aspen Plus-model including all major process steps. The model input was based on data recently obtained on lab scale or in a process development unit. A number of different process configurations are presented in order to demonstrate how heat integration within the ethanol process significantly reduces the energy demand, and thereby the production cost. Co-location and integration with a combined heat and power plant is discussed as a way to further increase the energy efficiency and improve the process economy.
Optical waveguide components for beam forming in phased-array antennas (1997)

A four-channel array of rf modulated laser signals was generated in a LiNbO3 optical waveguide network by heterodyne mixing of two input lightwaves. Independent control of the rf phase in each channel was provided by integrated optical phase shifters. An optical frequency shifter was demonstrated to produce the required input signals. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 46–49, 1997.
Distribution of targets for avian retrovirus DNA integration in vivo. (1994)

The targeting of DNA integration in retrovirus-infected cells is a central yet very poorly understood aspect of the biology of the virus. To investigate this problem, we have assessed the use of specific sites for integration targets of avian leukosis virus (ALV) DNA within defined regions of turkey embryo fibroblast (TEF) cellular DNA. For this purpose, we developed an assay of sufficient sensitivity and specificity to allow detection and location of single integration events in a population of 5 million cells. Targets selected for study were either regions cloned by virtue of a previous integration event or clones chosen at random from cellular DNA. By use of this approach, we found that all genomic regions tested contained integration targets, with a frequency that varied from approximately 0.2 to 4 times that expected for random integration. Within regions, the frequency of use of specific sites varied considerably, with some sites used up to 280 times random frequency. When one region was introduced into cells at moderately high copy number by transfection, it provided integration targets in a pattern very much like that seen with the same sequence in vitro. On the basis of our sampling, we conclude that most or all regions of the TEF genome are accessible to ALV retroviral integration. As with integration in vitro, integration specificity seems to be determined largely by local structural features rather than accessibility of specific regions.
Removable EBG Common Mode Filters (2017)

Subsequent to the introduction of the onboard electromagnetic bandgap (EGB)-based common mode filters, this chapter describes their evolution to removable EBG-based common mode (R-EBG CM) filters. This chapter describes the different topologies available for the removable EBG filters, ranging from the configuration with the traces kept on the main printed circuit board (PCB) to the one with the differential pair transitioning into the removable EBG. The removable EBG concept is powerful and can help many potential electromagnetic compatibility (EMC) issues. Among the various possible parameters, the impact of the number of patches forming the removable EBG geometry plays a significant role and is presented in this chapter. The chapter discusses the design of more elaborate removable EBG CM filters with two specific design examples. The first consideration addresses the reduction of the filter dimensions and therefore the space required on the main board. The second consideration concerns the trade-off between notch depth and notch bandwidth.
A QoS architecture for collaborative virtual environments (1999)

We present a QoS architecture for collaborative virtual environments (CVEs), focusing on the management of streamed video within shared virtual worlds. Users express QoS requirements by negotiating levels of mutual awareness using our previously defined spatial model of interaction. The architecture uses these awareness values as part of dynamic QoS management. A key aspect of the architecture is that it maintains a balance between the needs of a group of users as a whole (e.g., which streams are admitted onto a shared network) versus those of individual users within the group (e.g., which streams are subscribed to by a local host). We walk through a demonstration scenario, a virtual shopping mall, to show the architecture at work.
An efficient enhanced k-means clustering algorithm (2006)

In k-means clustering, we are given a set of n data points in d-dimensional space ℝd and an integer k and the problem is to determine a set of k points in ℝd, called centers, so as to minimize the mean squared distance from each data point to its nearest center. In this paper, we present a simple and efficient clustering algorithm based on the k-means algorithm, which we call enhanced k-means algorithm. This algorithm is easy to implement, requiring a simple data structure to keep some information in each iteration to be used in the next iteration. Our experimental results demonstrated that our scheme can improve the computational speed of the k-means algorithm by the magnitude in the total number of distance calculations and the overall time of computation.
Synthesis and Evaluation of Peptidyl Michael Acceptors That Inactivate Human Rhinovirus 3C Protease and Inhibit Virus Replication (1998)

Human rhinovirus, the chief cause of the common cold, contains a positive-sense strand of RNA which is translated into a large polyprotein in infected cells. Cleavage of the latter to produce the mature viral proteins required for replication is catalyzed in large part by a virally encoded cysteine proteinase (3Cpro) which is highly selective for -Q approximately GP- cleavage sites. We synthesized peptidyl derivatives of vinylogous glutamine or methionine sulfone esters (e.g., Boc-Val-Leu-Phe-vGln-OR: R = Me, 1; R = Et, 2) and evaluated them as inhibitors of HRV-14 3C protease (3Cpro). Compounds 1 and 2 and several related tetra- and pentapeptide analogues rapidly inactivated 3Cpro with submicromolar IC50 values. Electrospray mass spectrometry confirmed the expected 1:1 stoichiometry of 3Cpro inactivation by 1, 2, and several other analogues. Compound 2 also proved to be useful for active site titration of 3Cpro, which has not been possible heretofore because of the lack of a suitable reagent. In contrast to 1, 2, and congeners, peptidyl Michael acceptors lacking a P4 residue have greatly reduced or negligible activity against 3Cpro, consistent with previously established structure-activity relationships for 3Cpro substrates. Hydrolysis of the P1 vinylogous glutamine ester to a carboxylic acid also decreased inhibitory activity considerably, consistent with the decreased reactivity of acrylic acids vs acrylic esters as Michael acceptors. Incorporating a vinylogous methionine sulfone ester in place of the corresponding glutamine derivative in 1 also reduced activity substantially. Compounds 1 and 2 and several of their analogues inhibited HRV replication in cell culture by 50% at low micromolar concentrations while showing little or no evidence of cytotoxicity at 10-fold higher concentrations. Peptidyl Michael acceptors and their analogues may prove useful as therapeutic agents for pathologies involving cysteine proteinase enzymes.
CLINICAL APPLICATION OF EX VIVO PRODUCED ORAL MUCOSA EQUIVALENT (2006)

われわれの開発した培養複合上皮（皮膚，口腔粘膜）は，動物由来蛋白や3T3マウスfeeder layerを使用せずに完全無血清培地でkeratinocyteを培養した移植材料である。培養細胞を無細胞真皮上に播種して作製される培養複合上皮は，文部科学省高度先進医療開発経費Bの支援のもと，口腔粘膜上皮に関して新潟大学，富山大学，神戸大学の三施設合同で臨床応用され，平成14年～16年の三年間で106症例を数えた。その内52症例が口腔癌もしくはin situであり，結果として90症例で成功し，何らかの理由により16症例で不成功となった。この方法の利点は，異種移植と定義されないこと，理論上将来のプリオン病への危惧がほぼ皆無であること，把持縫合可能な操作性を有すことである。欠点として，無細胞であるが他人の真皮をscaffoldとして使用すること，作製に約一ヶ月を要することである。

DEVELOPMENT OF A NOVEL ULTRASONIC WAVEGUIDE TRANSDUCER FOR UNDER-SODIUM VIEWING (2011)

A novel ultrasonic waveguide transducer (UWT) has been developed for under‐sodium inspection of sodium‐cooled fast reactor (SFR). Its performance was evaluated and compared with other four types of waveguide designs. The signal transmission efficiency and detection sensitivity has been greatly improved. The preliminary results in molten sodium demonstrate that our novel ultrasonic waveguide transducer is able to achieve 1 mm lateral resolution and 0.5 mm vertical resolution in molten sodium with temperature ranged from 300 °F to 650 °F.
Observation of Asymmetric Stark Profiles from Plasmas Created by a Picosecond KrF Laser (1987)

High-resolution extreme-ultraviolet spectra from solid targets irradiated by a picosecond KrF laser focused to ${10}^{16}$ W/${\mathrm{cm}}^{2}$ have been recorded. The line profiles of transitions in Li-like fluorine and oxygen are asymmetric and up to 2 \AA{} in width. Calculations indicate the presence of transitions of the type $2p\ensuremath{-}3p$ and other forbidden Stark components.
MRI Study of Minor Physical Anomaly in Childhood Autism Implicates Aberrant Neurodevelopment in Infancy (2011)

Greater inter-orbital distance in the autism group compared with healthy controls is consistent with infant head size expansion in autism. Inter-orbital distance positively correlated with volume of medial temporal lobe structures, suggesting a link to "social brain" dysmorphology in the autism group. We suggest these data support the role of optical MPAs as a "fossil record" of early aberrant neurodevelopment, and potential biomarker for brain dysmaturation in autism.

Tailoring of Magnetocaloric Effect in Ni45.5Mn43.0In11.5 Metamagnetic Shape Memory Alloy (2012)

We investigate the direct and inverse magnetocaloric effect in Ni 45.5 Mn 43.0 In 11.5 Heusler alloy ribbons comparing the results obtained for the as-quenched sample with the ones after different annealing procedures. An enhancement and shift of the entropy maximum to near room temperature is observed in all annealed samples. A remarkable magnetocaloric effect is observed in samples with short-time treatment (10 minutes) and at the lowest annealing temperature. We show that the suppressing of uncompensated martensitic transition and thermal hysteresis are both influenced by the heat treatment. Also, an improvement on Curie’s temperature is observed and, at low magnetic field, it has been risen up to 310 K. Our results demonstrate that the martensitic transformation is highly sensitive to the applied magnetic field and also to the annealing treatment, which means that the magnetocaloric effect can be tuned showing different behaviors for each sample.
Molecular evolution and selection of a gene encoding two tandem microRNAs in rice (2007)

It has been shown that overexpression of MIR156b/c resulted in a bushy phenotype in maize and rice. Our results indicated that the MIR156b/c locus was highly conserved among cereals, but not in dicots and that genome duplication events played an important role in the evolution of the miR156 family. Genetic diversity investigation at the locus indicated that only approximately 9% of nucleotide diversity observed in wild rice (O. rufigogon) was maintained in the cultivated rice and the neutral model was rejected (P<0.05) based on Tajima's D and Fu and Li's D( *) and F( *) tests. To our knowledge, this is the first example of miRNA gene to be targeted by both natural and domestication selection in plants.
Bandit Models of Human Behavior: Reward Processing in Mental Disorders (2017)

Drawing an inspiration from behavioral studies of human decision making, we propose here a general parametric framework for multi-armed bandit problem, which extends the standard Thompson Sampling approach to incorporate reward processing biases associated with several neurological and psychiatric conditions, including Parkinson's and Alzheimer's diseases, attention-deficit/hyperactivity disorder (ADHD), addiction, and chronic pain. We demonstrate empirically that the proposed parametric approach can often outperform the baseline Thompson Sampling on a variety of datasets. Moreover, from the behavioral modeling perspective, our parametric framework can be viewed as a first step towards a unifying computational model capturing reward processing abnormalities across multiple mental conditions.
Enantioselective inhibition of the SARS-CoV-2 main protease with rhenium(i) picolinic acid complexes (2022)

Infections of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have triggered a global pandemic with millions of deaths worldwide. Herein, the synthesis of functionalized Re(i) tricarbonyl complexes as inhibitors of the SARS-CoV-2 main protease, also referred to as the 3-chymotrypsin-like protease (3CL<sup>pro</sup>), is presented. The metal complexes were found to inhibit the activity of the enzyme with IC<sub>50</sub> values in the low micromolar range. Mass spectrometry revealed that the metal complexes formed a coordinate covalent bond with the enzyme. Chiral separation of the enantiomers of the lead compound showed that one enantiomer was significantly more active than the other, consistent with specific binding and much like that observed for conventional organic small molecule inhibitors and druglike compounds. Evaluation of the lead compound against SARS-CoV-2 in a cell-based infection assay confirmed enantiospecific inhibition against the virus. This study represents a significant advancement in the use of metal complexes as coordinate covalent inhibitors of enzymes, as well as a novel starting point for the development of novel SARS-CoV-2 inhibitors.
Chest Pain Evaluation in the Emergency Department: Can MDCT Provide a Comprehensive Evaluation? (2005)

ECG-gated MDCT appears to be logistically feasible and shows promise as a comprehensive method for evaluating cardiac and noncardiac chest pain in stable emergency department patients. Further hardware and software improvements will be necessary for adoption of this paradigm in clinical practice.
An Overview of the Intel TFLOPS Supercomputer (1998)

Computer simulations needed by the U.S. Department of Energy (DOE) greatly exceed the capacity of the world&amp;apos;s most powerful supercomputers. To satisfy this need, the DOE created the Accelerated Strategic Computing Initiative (ASCI). This program accelerates the development of new scalable supercomputers and will lead to a supercomputer early in the next century that can run at a rate of 100 trillion floating point operations per second (TFLOPS). Intel built the first computer in this program, the ASCI Option Red Supercomputer (also known as the Intel TFLOPS supercomputer). This system has over 4500 nodes, 594 Gbytes of RAM, and two independent 1 Tbyte disk systems. Late in the spring of 1997, we set the MP LINPACK world record of 1.34 TFLOPS. In this paper, we give an overview of the ASCI Option Red Supercomputer. The motivation for building this supercomputer is presented and the hardware and software views of the machine are described in detail. We also briefly discuss what it is like to use the machine.
