Demonstration of plasma beat wave acceleration of electrons from 2 MeV to 20 MeV (2002)

We describe the results from recent experimental on the plasma beat wave accelerator (PBWA) scheme at UCLA. A relativistic electron plasma wave (which is the accelerating structure) is resonantly excited in a plasma by the beating of two co-propagating electromagnetic waves (obtained from a CO/sub 2/ laser operating simultaneously on two wavelengths). A 2 MeV, 200 mA (peak-current) electron beam, roughly 1 nsec (FWHM) in duration is used as a source of test particles for measuring the longitudinal fields of the plasma wave which itself is moving with a relativistic Lorentz factor of about 34. Accelerated electrons are energy-selected with an imaging sector magnet and detected simultaneously with a cloud chamber and surface barrier detectors. Initial experiments show that electrons are accelerated up to 20 MeV over roughly 1 cm (the uniform length of plasma) indicating an gradient of acceleration of more than 1.8 GeV/m.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Production of beta-1,4-xylanase by Aureobasidium pullulans DSM-73015: stimulatory effect of ethylene diamine tetraacetic acid [EDTA] (1999)

Aureobasidium pullulans DSM-73015 grown on modified Biely's medium with different carbon sources at 1% concentration secreted very low levels of β-1,4-xylanase (148.4-4680.9 nkat mL -1 ; 675.1-9752.0 nkat/mg protein). Xylose was the best carbon source inducer upon addition of EDTA and NH 4 NO 3 simultaneously into the culture medium. In this case, both the volumetric and specific activities increased up to 4680.9 nkat mL -1 and 9752.0 nkat/mg protein. The highest volumetric ( 13080.9 nkat mL -1 ) and specific activity (14964.6 nkat/mg protein) were obtained after 96 h of cultivation on 3% xylose-containing medium supplemented with EDTA and NH 4 NO 3 at 0.06% and 0.6% (w/v) concentrations, respectively, at an initial pH value of 4. Added EDTA showed concentration-dependent stimulatory effect on β-1,4-xylanase synthesis and about 16.7-22 and 1.5-22-folds increase in both volumetric and specific activities were achieved compared to that obtained initially on Biely's medium at 1% xylose concentration.
Down‐regulation of human RNA/DNA helicase SUV3 induces apoptosis by a caspase‐ and AIF‐dependent pathway (2007)

In addition to its mitochondrial localization, human SUV3 plays an important role in the nucleus and is probably involved in chromatin maintenance.
High Breakdown Voltage InAlAs/InGaAs High Electron Mobility Transistors on GaAs with Wide Recess Structure (1999)

Both an off-state breakdown voltage between a gate and a drain ( B V gd ) and maximum frequency of oscillation ( f max ) are described as functions of the width of gate recess in an InAlAs/InGaAs high electron mobility transistor (HEMT), using a new analysis model. The model suggests that the wide recess structure can improve both B V gd and f max , which is experimentally confirmed. We fabricated InAlAs/InGaAs HEMTs lattice-mismatched to GaAs substrates with optimum recess width, and these exhibited both a high B V gd of 14 V and a high f max of 127 GHz at a gate length of 0.66 µm.
From Childhood Conduct Problems to Poor Functioning at Age 18 Years: Examining Explanations in a Longitudinal Cohort Study (2017)

Children with severe conduct problems display poor functioning at age 18 years because of concurrent problems in early adulthood and familial risk factors originating in childhood. However, conduct problems also exert a lasting effect on young people's lives independent of these factors, pointing to early conduct problems as a target for early interventions aimed at preventing poor functional outcomes.
Continuous Spinal Drainage in the Treatment of Postoperative Cerebrospinal-Fluid Fistulae (1964)

T HE development of a cerebrospinal-fluid fistula within the dural envelope of the nervous system after an operation creates a dangerous situation. Surface pathogens or established infection of the wound may gain quick entrance to the leptomeningeal spaces, and patient and surgeon are faced with the grave consequences of an established leptomeningitis or cerebritis. Postoperative cerebrospinal-fiuid fistulae are fortunately unusual since very early in the development of operations on the nervous system surgeons realized there was no substitute for primary healing of the wound. This became routine with the use of stringent asepsis, gentle and meticulous surgical technique, debridement and the closure in layers of a clean dry wound. Special attention was devoted to careful dural closure whenever possible. However, the occasional development of a cerebrospinal-fluid leak in a disrupted surgical wound demands urgent treatment. General surgical principles again dictate the drainage of established infection of the wound and removal of dead tissue and foreign bodies to encourage delayed secondary healing. Clean disrupted wounds should be closed immediately but this rarely was possible with infected wounds. Great difficulty often attends the closure of a clean, but disrupted, laminectomy wound for the tissues are edematous and friable, making closure of layers impossible. Large throughand-through sutures may be the only means of approximation, tearing and strangulating large portions of muscle and fascia. A persevering cerebrospinal-fluid fistula flooding the wound retards the natural events of healing of the wound. Diversion of the stream is the basic principle promoting closure of fistulae when direct
Colocalization of ghrelin<i>O</i>-acyltransferase and ghrelin in gastric mucosal cells (2009)

Ghrelin is a peptide hormone with many known functions, including orexigenic, blood glucose-regulatory, and antidepressant actions, among others. Mature ghrelin is unique in that it is the only known naturally occurring peptide to be posttranslationally modified by O-acylation with octanoate. This acylation is required for many of ghrelin's actions, including its effects on promoting increases in food intake and body weight. GOAT (ghrelin O-acyltransferase), one of 16 members of the MBOAT family of membrane-bound O-acyltransferases, has recently been identified as the enzyme responsible for catalyzing the addition of the octanoyl group to ghrelin. Although the initial reports of GOAT have localized its encoding mRNA to tissues known to contain ghrelin, it is as yet unclear whether the octanoylation occurs within ghrelin-producing cells or in neighboring cells. Here, we have performed dual-label histochemical analysis on mouse stomach sections and quantitative PCR on mRNAs from highly enriched pools of mouse gastric ghrelin cells to demonstrate a high degree of GOAT mRNA expression within ghrelin-producing cells of the gastric oxyntic mucosa. We also demonstrate that GOAT is the only member of the MBOAT family whose expression is highly enriched within gastric ghrelin cells and whose whole body distribution mirrors that of ghrelin.
Dissociation of Ethoxy Methyl Carbenium Hexachloroantimonate in Methylene Chloride Solution. I. Measurement of the Specific Conductivity and Dielectric Constant (1977)

Abstract The problems of measuring the specific conductivity of very low conductivity organic solutions are explored. A simple ac system using readily available components is described, and its limitations are examined. The low-frequency dielectric constant can also be determined with reasonable accuracy.
Carbon dioxide foaming and High-pressure rheology of polystyrene and polystyrene/organoclay nanocomposites (2007)

The polymer foam industry is slowly implementing carbon dioxide (CO 2 ) as a low-cost, safe, and environmentally friendly blowing agent alternative to fluorocarbons and hydrocarbons.Progress is slow due to several obstacles, ranging from low blowing agent solubility to a lack of quantitative understanding of the influence of carbon dioxide on viscosity.A crucial property in foam extrusion is viscosity.Several research groups have published viscosity data of polymer melts under high pressure, using a variety of techniques.However, few studies assist in designing polymer processing equipment because most do not contain predictive scaling (e.g., WLF-analogous scaling factors) to apply to different operating conditions.A new high-pressure rotational rheometer has been applied to polystyrene and carbon dioxide at five concentrations.It provides direct measurement of the zero shear viscosity of the polymer under a high pressure diluent.The method allows many viscosity measurements to be performed on a single sample.Scaling factors are applied to the data and the WLF-Chow equation is found to describe the results when the appropriate parameter is selected.iii Due to an interest in using organoclay nanoparticles for foaming, the viscosity of the polystyrene-nanoclay-CO 2 system is studied using the couette rheometer and an extruder slit die.At high shear rates (10 to 100 s -1 ), the viscosity of polystyrene-nanoclay-CO 2 unexpectedly possesses a lower viscosity than polystyrene-CO 2 at the same concentration.At low shear rates (10 -3 to 1 s -1 ), this effect is not observed.It is suspected that interfacial slip is occurred at the interface at high shear rates.Polymer additives allow tuning of bubble morphology without changing operating conditions.In this study, either a second polymer or nanoparticles are studied.Poly (methyl methacrylate) (PMMA) has the ability to drastically reduce cell size of polystyrene (PS) foams.It is believed that heterogeneous nucleation occurs at the interface of PS/PMMA, but that the bubbles are able to grow out of both phases simultaneously.
Intracoronary Stenting and Risk for Major Adverse Cardiac Events During the First Month (1998)

These results underscore the importance of optimal angiographic results and the need for antiplatelet regimens with immediate onset. Our risk stratification protocol may guide individual postprocedural care and allow us to compare risk profiles of different study populations and to devise quality control programs for stenting.
Linking open drug data (2009)

astrazeneca.com Abstract: The development of new therapies for diseases requires the integration of large amounts of biomedical data from many different sources. The goal of the Linking Open Drug Data (LODD) 1 project is to facilitate this integration by bringing these data sources onto the Web of Linked Data. We describe the different datasets published by this project, which are strongly interlinked with other Linked Data sources and contain 8.4 million RDF triples. A use case is provided that demonstrates the benefit of this work to patients and medical researchers. 1
Role of CREB transcription factor in c-fos activation in natural killer cells (2002)

In natural killer (NK) cells, interleukin-2 (IL-2) differentially regulates the expression of several transcription factors, including JunB and c-fos. The cAMP response element binding protein, CREB, is a key transcriptional regulator of a large number of genes containing the octanucleotide CRE consensus sequence in their upstream regulatory regions. We studied here the functional role of CREB in the IL-2-mediated transcriptional regulation of c-fos in human NK cells. Our results show that IL-2 activates CREB in human NK cells and that CREB activation hasa prominent regulatory role on the IL-2-induced expression of functional c-fos and AP-1 in NK cells. We identify two domains of the c-fos promoter, containing three CRE sites, which are critical for the transcriptional activity induced by IL-2. The first domain is located within the first 220 nucleotides of the c-fos promoter, while the second encompasses the nucleotides - 440 and - 220. Our results show that CREB has a relevant role in the cytokine-mediated activation of NK cells, and are particularly remarkable in the light of the several genes that are positively regulated by c-fos and AP-1, such as IFN-gamma, IL-2 and GM-CSF genes.
Compact, Engineered 2-Micron Coherent Doppler Wind Lidar Prototype for Field and Airborne Evaluation (2006)

The state-of-the-art 2-micron coherent Doppler wind lidar breadboard at NASA/LaRC will be engineered and compactly packaged consistent with future aircraft flights. The packaged transceiver will be integrated into a coherent Doppler wind lidar system test bed at LaRC. Atmospheric wind measurements will be made to validate the packaged technology. This will greatly advance the coherent part of the hybrid Doppler wind lidar solution to the need for global tropospheric wind measurements.
New transmission systems enabling transparent network perspectives (2008)

The emergence of new devices and technologies introduces new trends and design issues for optical transport networks. The higher performance of transmission and switch systems enables the reduction of optoelectronic conversions in intermediate nodes with the introduction of transparency in the network. Simultaneously, the system of Automatic Switched Optical Networks (ASON) describes the rules for the construction of a network enabling cost reduction, above all for maintenance, and fast and automatic reconfiguration. Two axes have to evolve to make possible all these proprieties: the control plane and its relative set of protocols, to manage the network working for the network automation, and also the systems and tools enabling transparency and reconfigurability. In this article we focus on the second axis applied to an automatic transparent network.
The histone H3.3K27M mutation in pediatric glioma reprograms H3K27 methylation and gene expression (2013)

Recent studies have identified a Lys 27-to-methionine (K27M) mutation at one allele of H3F3A, one of the two genes encoding histone H3 variant H3.3, in 60% of high-grade pediatric glioma cases. The median survival of this group of patients after diagnosis is ∼1 yr. Here we show that the levels of H3K27 di- and trimethylation (H3K27me2 and H3K27me3) are reduced globally in H3.3K27M patient samples due to the expression of the H3.3K27M mutant allele. Remarkably, we also observed that H3K27me3 and Ezh2 (the catalytic subunit of H3K27 methyltransferase) at chromatin are dramatically increased locally at hundreds of gene loci in H3.3K27M patient cells. Moreover, the gain of H3K27me3 and Ezh2 at gene promoters alters the expression of genes that are associated with various cancer pathways. These results indicate that H3.3K27M mutation reprograms epigenetic landscape and gene expression, which may drive tumorigenesis.
Impact Study of High Biodiesel Blends on Performance of Exhaust Aftertreatment Systems (2008)

<div class="htmlview paragraph">Biodiesel Fuel (BDF) Research Work Group works on identifying technological issues on the use of high biodiesel blends (over 5 mass%) in conventional diesel vehicles under the Japan Auto-Oil Program started in 2007. The Work Group conducts an analytical study on the issues to develop measures to be taken by fuel products and vehicle manufacturers, and to produce new technological findings that could contribute to the study of its introduction in Japan, including establishment of a national fuel quality standard covering high biodiesel blends. For evaluation of the impacts of high biodiesel blends on performance of diesel particulate filter system, a wide variety of biodiesel blendstocks were prepared, ranging from some kinds of fatty acid methyl esters (FAME) to another type of BDF such as hydrotreated biodiesel (HBD). Evaluation was mainly conducted on blend levels of 20% and 50%, but also conducted on 10% blends and neat FAME in some tests. The evaluation test items include balance point temperature (BPT), DPF regeneration rate, active regeneration control of DPF system, PM composition analysis, and so on. The study results showed that high biodiesel blends had a small impact on BPT and DPF regeneration rate. On the other hand, concern was raised about high biodiesel blends in active regeneration control of DPF.</div>
Optimization of Hybrid J JKMOS Memory Operating Temperatures (1997)

A major drawback of present superconducting electronics is the lack of suitable large scale memory. One approach to circumvent this problem is to use semiconducting CMOS memory in conjunction with the fast Josephson junction (JJ) logic. This requires operating the CMOS memory at cryogenic temperatures. The speed of CMOS circuits has been shown to increase at cryogenic temperatures. Further increase in speed can be obtained by using JJ sense circuits in the CMOS memory. Preliminary results show that access time of 1.5 ns should be possible with this hybrid JJKMOS approach using 1.2 micron CMOS, and JJ sense and interface circuits. We also report the results of an analysis of the optimal operating temperature of such hybrid memories in conjunction with refrigeration requirements in light of the emerging cryocooler technologies.
A quantitative study of pinning of a 2D electron crystal in heterojunctions (1993)

The author studies numerically the relaxation and the pinning gap of a 2D electron crystal in the presence of randomly distributed distant dopants. The results agree with experiments and with analytic calculations based on a perturbation in the deviations of the particle positions delta r/a from the lattice positions. For parameters corresponding to the recent experimental studies (d/a approximately=3), the relaxation is dominated by the longitudinal mode.
Environmental observations from space present and future (1978)

Spaceborne systems for measuring and predicting environmental conditions have achieved a level of development that justifies a look at the total environmental system. There are common requirements in all the disciplines, and many of the same measurements are needed to satisfy various discipline needs. It is this factor - the commonality of needs and measurements - that will be used in our future missions. The needs and requirements in the future plan will be faced by combining mission and data requirements that may be satisfied from orbiting spacecraft. There are also similarities in information requirements, as a result of which there is a need for developing an integrated data/information system where information will be produced in a format that will be of immediate utility to the users.
The development of a solid phase extraction (SPE) system for environmental monitoring (2004)

This presentation describes the development of an automated solid phase extraction (SPE) device, developed from a 50 port extraction unit (Aqualab) coupled with an SPE disc holder containing a C18 speedisk <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> . The device has been tested in the laboratory over 20 days in a tank spiked with antifouling paints and the extracts collected tested for the presence of Irgarol 1051, SeaNine 211 and diuron. The data show no significant reduction in recovery when leaving discs in the water, compared to removing on the day of exposure, making this a good technique for analysing such compounds over long periods of time.
Dominant interferer mitigation in closed femtocell deployment (2010)

In this paper, we analyze the interference distribution and gain of beamforming in closed access femtocells in downlink of a two-tier HSDPA cellular network. We show through simulations that indoor femtocell deployment leads to a dominant interferer scenario. According to results even simple null steering method based on the scarce codebook of HSDPA transmit diversity mode 1 can be beneficially applied. Performance evaluations are carried out through HSDPA compliant system simulations.
PANEMOTO: Network Visualization of Security Situational Awareness Through Passive Analysis (2007)

To maintain effective security situational awareness, administrators require tools that present up-to-date information on the state of the network in the form of 'at-a-glance' displays, and that enable rapid assessment and investigation of relevant security concerns through drill-down analysis capability. In this paper, we present a passive network monitoring tool we have developed to address these important requirements, known as Panemoto (Passive Network Monitoring Tool). We show how Panemoto enumerates, describes, and characterizes all network components, including devices and connected networks, and delivers an accurate representation of the function of devices and logical connectivity of networks. We provide examples of Panemoto's output in which the network information is presented in two distinct but related formats: as a clickable network diagram (through the use of NetViz, a commercially available graphical display environment) and as statically-linked HTML pages, viewable in any standard web browser. Together, these presentation techniques enable a more complete understanding of the security situation of the network than each does individually.
Crystal Structure of the Malic Enzyme from <i>Ascaris suum</i> Complexed with Nicotinamide Adenine Dinucleotide at 2.3 Å Resolution<sup>,</sup> (2002)

The structure of the Ascaris suum mitochondrial NAD-malic enzyme in binary complex with NAD has been solved to a resolution of 2.3 A by X-ray crystallography. The structure resembles that of the human mitochondrial enzyme determined in complex with NAD [Xu, Y., Bhargava, G., Wu, H., Loeber, G., and Tong, L. (1999) Structure 7, 877-889]. The enzyme is a tetramer comprised of subunits possessing four domains organized in an "open" structure typical of the NAD-bound form. The subunit organization, as in the human enzyme, is a dimer of dimers. The Ascaris enzyme contains 30 additional residues at its amino terminus relative to the human enzyme. These residues significantly increase the interactions that promote tetramer formation and give rise to different subunit-subunit interactions. Unlike the mammalian enzyme, the Ascaris malic enzyme is not regulated by ATP, and no ATP binding site is observed in this structure. Although the active sites of the two enzymes are similar, residues interacting with NAD differ between the two. The structure is discussed in terms of the mechanism and particularly with respect to previously obtained kinetic and site-directed mutagenesis experiments.
