Effects of 7 Hz-modulated 450 MHz electromagnetic radiation on human performance in visual memory tasks (2002)

Purpose : The aim was to examine low-level 7 Hz-modulated 450 MHz radiation effects on human performance in visually presented neuropsychological tasks associated with attention and short-term memory. Materials and methods : A homogeneous group of 100 subjects (37 female, 63 male) were randomly assigned to either the exposed (10-20 min, 0.158mW cm -2) or the sham-exposed group. A battery of three different tests measured attention and shortterm memory. Task 1 involved alternately selecting black digits from 1 to 25 in ascending order and white digits from 24 to 1 in descending order. The time spent on the task and the number of errors were recorded and analysed. Task 2 involved viewing a picture of 12 objects during 3 s, followed by a list of 24 words. The subject was required to select words representing previously presented objects. In task 3, an array of letters in 10 rows (60 in each row) was presented, and the subject was required to identify all examples of a particular two-letter combination. Results : The results of tasks 1 and 3 showed a significant increase in variances of errors (p <0.05) in the exposed versus the shamexposed group. The results of task 2 indicated a significant decrease in errors (p <0.05) in the exposed group. Conclusions : The data provide additional evidence that acute lowlevel exposure to microwaves modulated at 7 Hz can affect cognitive processes such as attention and short-term memory.
Migraine Prophylaxis, Ischemic Depolarizations, and Stroke Outcomes in Mice (2014)

These data underscore the importance of hyperexcitability as a mechanism for increased stroke risk in migraineurs, and suggest that migraine prophylaxis may not only prevent migraine attacks but also protect migraineurs against ischemic injury.
Prenatal screening for trisomy 21: recent advances and guidelines (2011)

The performance of prenatal screening tests for the identification of trisomy 21 (Down syndrome) has markedly improved since the 1970s and early 1980s when maternal age was the sole mode of screening the general pregnant population. With the discovery of second trimester serum markers in the 1980s and 1990s and implementation of double, triple, and quad marker testing; the discovery of first trimester serum and ultrasound markers in the 1990s and implementation of the combined test; and the development of the integrated test and sequential screening strategies over the past decade, the performance of screening has improved to a detection rate of 90%–95% at a false positive rate of 2%–5%. In this review, I will describe the advances in prenatal screening for trisomy 21, present current screening strategies, and discuss guidelines published by professional societies and regulatory bodies, with a focus on current prenatal screening practice in the USA.
Best-estimate LOCA radiation signature for equipment qualification. [PWR; BWR] (1980)

The radiation aspect of reactor equipment qualification depends on a knowledge of the appropriate source term. An attempt has been made to define a realistic radiation source corresponding to the loss-of-coolant accident. This best-estimate source is based on available fission product release data from damaged fuel during an unterminated LOCA as described in the Reactor Safety Study (WASH-1400). Energy release rates as a function of time have been calculated for both betas and gamma rays. The results are significantly different from the sources specified in Regulatory Guide 1.89. Spectra corresponding to the best-estimate source have also been computed at selected cooling times.
Enterprise network management: LAN status monitoring (2002)

During the past few years, the study of network management has focused on a single node, e.g., a router or a hub. As network connectivity and heterogeneity grows, there is a need to extend the scope of management from a few nodes to an enterprise environment where there is a number of networks interconnected by switching devices. In this paper, we attempt to provide a configuration, fault, and performance monitoring solution in an enterprise LAN network environment. First, we identify the managed objects which are subject to monitoring. Among the important managed objects are interconnection domains, switching devices, and LAN networks such as Ethernet, token ring and FDDI networks. Then we identify the management functions which can be applied during the monitoring process. Using scenarios, we demonstrate how these management functions can be applied.
Tumor Necrosis Factor Alpha Receptor I Is Important for Survival fromStreptococcus pneumoniaeInfections (1999)

Tumor necrosis factor alpha (TNF-alpha) is important in resistance to various microorganisms and provides signals to the target cells through two different receptors, TNF-alpha receptor I (TNFRI) (p55 receptor) and TNFRII (p75 receptor). To delineate the significance of the two different signaling pathways in resisting infections with extracellular bacteria, we examined the resistance of mice to Streptococcus pneumoniae (serotype 6B). TNF-alpha needs to be present early in infections, since one injection of wild-type mice with anti-TNF-alpha leads to an increased susceptibility of these mice to S. pneumoniae. TNF-alpha signaling through the p55 receptor (but not the p75 receptor) is crucial in resisting S. pneumoniae infections, because intraperitoneal injection of 100 CFU/mouse killed p55-deficient mice by day 2 of infection, whereas 1,000,000 CFU/mouse was needed to kill half of the control mice. p55-deficient mice do not show evidence of a deficient acute-phase response. All three types of mice (p55 deficient, p75 deficient, and normal) showed comparable rises in the levels of two acute-phase proteins (serum amyloid P and C3) at 24, 48, and 72 h after the experimental infections, and all of the mice showed comparable influxes of neutrophils to the site of infection. Finally, it was demonstrated that p55-deficient mice can be protected from the lethal effects of S. pneumoniae infection by injection of antibodies specific for S. pneumoniae polysaccharide capsule.
PowerLyra (2018)

Natural graphs with skewed distributions raise unique challenges to distributed graph computation and partitioning. Existing graph-parallel systems usually use a “one-size-fits-all” design that uniformly processes all vertices, which either suffer from notable load imbalance and high contention for high-degree vertices (e.g., Pregel and GraphLab) or incur high communication cost and memory consumption even for low-degree vertices (e.g., PowerGraph and GraphX). In this article, we argue that skewed distributions in natural graphs also necessitate differentiated processing on high-degree and low-degree vertices. We then introduce PowerLyra, a new distributed graph processing system that embraces the best of both worlds of existing graph-parallel systems. Specifically, PowerLyra uses centralized computation for low-degree vertices to avoid frequent communications and distributes the computation for high-degree vertices to balance workloads. PowerLyra further provides an efficient hybrid graph partitioning algorithm (i.e., hybrid-cut) that combines edge-cut (for low-degree vertices) and vertex-cut (for high-degree vertices) with heuristics. To improve cache locality of inter-node graph accesses, PowerLyra further provides a locality-conscious data layout optimization. PowerLyra is implemented based on the latest GraphLab and can seamlessly support various graph algorithms running in both synchronous and asynchronous execution modes. A detailed evaluation on three clusters using various graph-analytics and MLDM (Machine Learning and Data Mining) applications shows that PowerLyra outperforms PowerGraph by up to 5.53X (from 1.24X) and 3.26X (from 1.49X) for real-world and synthetic graphs, respectively, and is much faster than other systems like GraphX and Giraph, yet with much less memory consumption. A porting of hybrid-cut to GraphX further confirms the efficiency and generality of PowerLyra.

Heritability of Resistance to Verticillium Wilt in Alfalfa (2006)

Verticillium wilt of alfalfa, caused by Verticillium albo-atrum, may reduce forage yields by up to 50% in alfalfa-producing areas of the northern United States and Canada. It has been suggested that cultivars require at least 60% resistant plants to afford maximum protection against disease. Our objective was to calculate heritability estimates of resistance to Verticillium wilt in alfalfa. Estimates were generated for two alfalfa populations developed from the cvs. Affinity + Z and Depend + EV. Heritability on a half-sib progeny means basis was calculated based on data from greenhouse pathogenicity tests. Estimates based on repeated experiments conducted for single years (2004 and 2005) were high for both populations, ranging from 0.86 to 0.92. The heritability estimate based on data collected over 2 years was 0.26 for Affinity + Z and 0.66 for Depend + EV. Disease was more severe in 2005 than in 2004. However, the Spearman rank correlation between mean disease severity index values for half-sib families over 2 years was positive and significant for both populations. Results of pathogenicity tests suggested that neither cultivar had resistance levels approaching 60%. The heritability estimates suggest that resistance levels in both Affinity + Z and Depend + EV could be improved further through selection.

A comparative study between midazolam and thiopental alone or with analgesic and neuroleptic as intravenous induction agents in general anesthesia. (1987)

A new method to describe intensive care department performance is presented. The method is a complication of available administrative and medical data, completed with a severity of illness measure (Acute Physiology And Chronic Health Evaluation, APACHE) and the registration of nursing care intensity. The development of this latter patient stratification system (Intensive Care Activity Score, INCAS) is described. The performance of the method is demonstrated by a study of 200 consecutive admissions.

Distributed labelling of audio sources in wireless acoustic sensor networks using consensus and matching (2016)

In this paper, we propose a new method for distributed labelling of audio sources in wireless acoustic sensor networks (WASNs). We consider WASNs comprising of nodes equipped with multiple microphones observing signals transmitted by multiple sources. An important step toward a cooperation between the nodes, e.g. for a voice-activity-detection, is a network-wide consensus on the source labelling such that all nodes assign the same unique label to each source. In this paper, a hierarchical approach is applied such that first a network clustering algorithm is performed and then in each sub-network, the energy signatures of the sources are estimated using a non-negative independent component analysis over the energy patterns observed by the different nodes. Finally the source labels are obtained by an iterative consensus and matching algorithm, which compares and matches the energy signatures estimated in different sub-networks. The experimental results show the effectiveness of the proposed method.
A Limitation regarding the Use of Ethanol Stabilized Chloroform as a Solvent for Infrared Spectroscopy (1961)

It was observed in this laboratory that the infrared spectra of many compounds, transparent in the region from 2.8 to 3.0 microns in both carbon tetrachloride and carbon disulfide solutions, showed a weak absorption band in this region when their infrared spectra were run as chloroform solutions (Chloroform, Mallinckrodt, Anal. Reag., 0.75% of ethanol added as a preservative), employing the same grade of chloroform in the reference cell. This fact precluded the use of chloroform as an infrared solvent when it was desired to detect small amounts of —OH or > NH in the 2.9 micron region.
Photoluminescence assessment of B, P, and Al in Si wafers: The problem of sample heating by a laser beam (1993)

A line shape analysis of free-exciton low-temperature (4.2 K) photoluminescence spectra is applied to monitor the heating of Si samples due to an exciting Ar+-ion laser beam. The heating is studied in dependence on the laser beam intensity. The temperature as a line shape fitting parameter can be established within ±0.15 K. Continuous minor increase of the sample temperature is observed up to an intensity of ∼200 W cm−2, followed by an abrupt temperature jump up to tens of K. Possible inaccuracies, resulting from the heating, in photoluminescent quantitative determination of boron, phosphorus, and aluminum are discussed.
Organising disordered matter: strategies for ordering the network of mesoporous materials (2005)

Several synthesis strategies used to obtain hydrothermally stable and highly active catalysts based on ordered mesoporous materials are reviewed in this contribution. It is experimentally observed that the use of zeolite precursors as building blocks of the mesoporous network yields the most stable materials. However, the nature of the mesoporous framework of these solids remains still unknown, and basic understanding of the assembling process of zeolite precursors and surfactants has not yet been achieved. Some key features of the whole process are explored, and examples that illustrate its chemical and structural complexity are provided.
High-speed systolic array for gene matching (2004)

One of the main challenges in bioinformatics nowadays is to create a framework to compare efficiently new DNA sequence information to large existing databases. Optimal methods, such as the Smith-Waterman algorithm, provides more sensitive results than heuristic algorithms such as FASTA and BLAST, with the drawback of increased computational complexity. FPGAs implementations of Smith-Waterman exploit the intrinsic parallelism in the algorithm and achieve computation time reductions of several orders of magnitude. In this paper we present an implementation of a Smith-Waterman linear systolic array that doubles throughput of existing ones with a minimum increase of area. The processing speed improvement is achieved by means of assigning the computation of four edit distances to a single systolic cell. Implementation results on Xilinx devices XC2V6000 and XCV1000E are reported. An array that processes 8000-nucleotid DNA sequences achieves 3200 BCUPS operating at 200 Mhz on a XC2V6000-5 device.
Angular distribution of thick-target bremsstrahlung produced by electrons with initial energies ranging from 10 to 20 keV incident on Ag (2011)

Experimental results are presented comparing the intensities of the bremsstrahlung produced by electrons with initial energies ranging from 10 to 20 keV incident on a thick Ag target, measured at forward angles in the range of 0\ifmmode^\circ\else\textdegree\fi{} to 55\ifmmode^\circ\else\textdegree\fi{}. When the data are corrected for attenuation due to photon absorption within the target, the results indicate that the detected radiation is distributed anisotropically only at photon energies $k$ that are approximately equal to the initial energy of the incident electrons ${E}_{0}$. The results of our experiments suggest that, as $k$/${E}_{0}$ \ensuremath{\rightarrow} 0, the detected radiation essentially becomes isotropic due primarily to the scattering of electrons within the target. A comparison to the theory of Kissel et al. [At. Data Nucl. Data Tables 28, 381 (1983)] suggests that the angular distribution of bremsstrahlung emitted by electrons incident on thick targets is similar to the angular distribution of bremsstrahlung emitted by electrons incident on free-atom targets only when $k$/${E}_{0}$ \ensuremath{\approx} 1. The experimental data also are in approximate agreement with the angular distribution predictions of the Monte Carlo program penelope.
Jitter Analysis of Nonautonomous MOS Current-Mode Logic Circuits (2008)

In this paper, we analyze the occurrence of jitter due to random and deterministic disturbances in nonautonomous current-mode logic circuits. First, we present an analytical model that explains the transformation of noise into jitter as a linear time-variant process, with its time-domain impulse response function and a frequency-domain system function. The model is then used to analyze jitter in two different circuits, with different sources of noise. In the first example, we use the model to predict jitter due to device noise in a frequency divider, and identify devices that are the main contributors to the jitter. In the second example, we examine jitter of a buffer with deterministic ground noise. Jitter predictions are compared to the results obtained through exhaustive simulation. According to the comparison, the method predicts jitter with an error of up to 3.4%.
Broad Beamwidth and Cross Polarization Free Dipole Antennas With Reactive Loaded Monopoles (2007)

A method to broaden the E-plane radiation pattern of a dipole antenna over a ground plane is proposed. Two parasitic monopole elements with reactive loads are placed in the vicinity of the driving dipole element. Another advantage of this antenna is that these monopoles do not cause cross polarization in the H-plane. Based on the electromotive force (EMF) method, a new procedure that optimizes the load values is developed. Numerical verification by the method of moments (MoM) is provided; additionally, each antenna parameter including the optimum reactive load is obtained. The experiment is also presented to demonstrate the performance
Genetic Manipulation of Polyamine Catabolism in Rodents (2006)

Activation of polyamine catabolism through the overexpression of spermidine/spermine N1-acetyltransferase (SSAT) in transgenic rodents does not only lead to distorted tissue polyamine homeostasis, manifested as striking accumulation of putrescine, appearance N1-acetylspermidine and reduction of tissue spermidine and/or spermine pools, but likewise creates striking phenotypic changes. The latter include loss of hair, lipoatrophy and female infertility. Forced expression of SSAT modulates skin, prostate and intestinal carcinogenesis, induces acute pancreatitis and blocks early liver regeneration. Although many of these features are directly attributable to altered tissue polyamine pools, some of them are more likely related to the greatly accelerated flux of the polyamines caused by activated catabolism and compensatorily enhanced biosynthesis.
Adaptation of small intestinal membrane transport processes during diabetes mellitus in rats (1990)

Intestinal amino acid and glucose transport is increased in various disease states and physiological circumstances. This enhancement is generally due to an increase in transport capacity (Vmax) without a change in carrier affinity (KD). Furthermore, the increase in transport capacity is too large to be attributed, in most cases, to simple intestinal hypertrophy. In the streptozotocin-treated chronically diabetic rat model, specific binding indicated an enhanced total number of glucose carriers in the small intestine compared with controls. Furthermore, autoradiography reveals that specific phlorizin (i.e., glucose) binding extends into the intervillous region of the intestine, while in age-matched controls binding is confined to the villous tip. These studies suggest that during experimental diabetes mellitus in rats, enhanced intestinal nutrient absorption may occur as a consequence of recruitment of carriers into previously nontransporting enterocytes. This review looks at ways in which this alteration may be influenced, and examines the expression of various isoforms of Na-K ATPase during streptozocin-induced diabetes mellitus.
Specification of the Direction of Adhesive Signaling by the Integrin β Cytoplasmic Domain (2005)

Integrin adhesion receptors can signal in two directions: first, they can regulate cellular behaviors by modulating cellular signaling enzymes ("outside-in signaling"); second, cells can regulate the affinity of integrins ("inside-out signaling") by such pathways. Integrin beta cytoplasmic domains (tails) mediate both types of signaling, and Src family kinases (SFKs) and talin, which bind to beta tails, are important for integrin signaling. Here, we utilized "homology scanning" mutagenesis to identify beta tail mutants selectively defective in c-Src binding and found that amino acid exchanges affecting a combination of an Arg and Thr residue in the integrin beta3 tail control the binding specificity for SFKs but have no effect on talin binding. Using beta tail mutants at these residues, we found that SFK binding to integrin beta tails is dispensable for inside-out signaling but is obligatory for cell spreading, a marker of outside-in signaling. Conversely, we found that point mutations that disrupt talin binding abolish integrin activation, but they do not inhibit SFK binding to the beta3 tail or the initiation of outside-in signaling once the integrins are in a high affinity form. Thus, we show that inside-out and outside-in integrin signaling are mediated by distinct and separable interactions of the integrin beta tails. Furthermore, based on our results, it is possible to discern the relative contributions of the direction of integrin signaling on biological functions in cell culture and, ultimately, in vivo.
A stereoscopic display with a vibrating microlens array (2003)

In this paper, we demonstrate a prototype of a high-resolution stereoscopic display by vibrating a micro cylindrical lens array. This lens array is fabricated by melting photoresists and form transfer. The height and width of the cylindrical lens measured 12.5 /spl mu/m and 320 /spl mu/m, therefore the focal length is calculated as 1980 /spl mu/m. The lens array vibrates synchronously with the changeover of images which are displayed under the lens array. The brightness is measured at several view angles, and 9 degrees-parallax is observed on condition that the amplitude and cycle of the vibration are 100 /spl mu/m and 120 ms, respectively.
