Effect of Ternary Additions on the Room Temperature Lattice Parameter of Ni3Al (1992)

The room temperature lattice parameters of Ni3Al alloys with and without ternary additions are measured by X-ray diffraction. The lattice parameters of Ni3Al phase alloys increase with Al concentration. The addition of B, Hf, Zr, and Ti to Ni3Al increases the lattice parameter and Si additions decrease it. The results obtained are discussed in terms of crystal structure and atomic sizes. The lattice strain produced by the addition of Hf and Zr is found to be 0.09 and 0.11, respectively which is approximately three times less than that of boron addition (0.30), suggesting the substitutional nature of Hf and Zr and the interstitial nature of boron addition. Die Gitterparameter von Ni3Al-Legierungen mit und ohne eine dritte Komponente werden mittels Röntgenbeugung bei Raumtemperatur gemessen. Die Gitterparameter der Legierungen der Ni3Al-Phase steigen mit der Al-Konzentration. Der Zusatz von B, Hf, Zr und Ti vergrößert die Gitterkonstante von Ni3Al, der Zusatz von Si verringert sie. Dieses Ergebnis wird anhand der Kristallstruktur und der Atomgröße diskutiert. Die durch Hf und Zr erzeugte Gitterdehnung beträgt 0,09 bzw. 0,11, d. h. ist etwa dreimal kleiner als die durch Borzusatz erzeugte (0,30), was auf den Einbau von Hf und Zr auf Gitterplätzen und von Br auf Zwischengitterplätzen hindeutet.
Improvements to the Tractive Efficiency of Agricultural Tractors Carrying out Cultivations (2009)

Although draught control and maximum wheel slip control systems are common on agricultural tractors these are still set by the operator working to general guidelines and without quantitative feedback on the real time tractive efficiency. The aim of this paper is to propose and evaluate a system on tractors that allows tractive efficiency to be maximized. The paper considers the idea that an instrumented three point linkage allows the determination of an implement's draught force, its vertical force (weight addition) and the resultant force line of action in the longitudinal-vertical plane so that the dynamic wheel loads can be calculated. Implement force prediction can be used with traction models to determine the real time tractive efficiency and potential improvement in tractive efficiency.
Respiratory Syncytial Virus Nucleoprotein-Specific Cytotoxic T-Cell Epitopes in a South African Population of Diverse HLA Types Are Conserved in Circulating Field Strains (2003)

ABSTRACT This study identifies memory cytotoxic T lymphocyte (CTL) epitopes to respiratory syncytial virus (RSV) in healthy South African adults and demonstrates the conservation of those epitopes in circulating field strains of RSV in South Africa. Thirty-seven healthy adults from a population with diverse HLA backgrounds were screened by gamma interferon (IFN-γ) enzyme-linked immunospot for memory CTL activity in response to overlapping peptides representing the complete nucleoprotein (N) of RSV. Responses of more than 40 spot-forming cells/million cells were detectable in 21 individuals. The significant responses were further characterized, and 14-mer peptides were identified that induced cytolytic activity. Fine mapping of peptides with the highest cytolytic activity identified an HLA-B * 08-restricted RSV-specific CTL epitope. The extended 14-mer peptide containing this epitope also induced lysis in the context of A * 02-restricted target cells in some individuals. These HLA types are common in the target population; thus, the epitope is useful for studies of CTL responses to RSV in humans. The epitope was detected in healthy adults, reflecting the response generated in the course of previous natural RSV infection. We obtained a large panel of naturally occurring isolates of RSV to determine whether there was evidence of escape from CTL activity in circulating strains. We found that this epitope and a previously identified B * 07-restricted N protein epitope were conserved in RSV field strains representing the diversity of circulating genotypes. This work suggests that escape from CTL activity is not common for this acute respiratory infection.
Indexing of NFL Video using MPEG-7 Descriptors and MFCC features (2006)

In this paper, we propose an application system to classify American football (NFL) video shots into 4 categories, namely: pass plays, run plays, field goal/extra point plays (FG/XP) and kickoff/punt plays (K/P). The proposed system consists of two stages. The first stage is responsible for play event localization and the latter stage is responsible for feature mapping and classification. For play event localization we have proposed an algorithm that uses MPEG-7 motion activity descriptor and mean of the magnitudes of motion vectors, in a collaborative manner to detect the starting point of a play event within a video shot with 83% accuracy. The indexing and classification stage uses MPEG-7 motion and audio descriptors along with Mel Frequency Cepstrum Coefficients (MFCC) features to classify the events into 4 categories using Fisher's LDA. We obtain indexing accuracy of 92.5% by using a leave-one-out classification technique on a database of 200 video shots taken from 4 different games obtained from 4 different networks.
A new method for the activation of the locomotor circuitry in humans (2010)

We examined the possibility of initiation of involuntary stepping movements by spinal electromagnetic stimulation (SEMS) during leg suspension. The subject’s legs were supported by a special apparatus in a gravity neutral position that to provide horizontal rotation in the hip, knee and ankle. SEMS (3 Hz and 1.56 Tesla) over the T11–T12 vertebrae induced involuntary locomotor_like movements in the legs. The latency period from the initiation of stimulation to the first EMG burst was 0.68 1.0 s. Increasing the frequency of SEMS from 3 Hz to 20 Hz resulted in shortening of the latency period. Thus, SEMS is able to initiate involuntary stepping in humans.
Fully integrated super-regenerative bandpass filters for 3.1-to-7GHz multiband UWB system (2008)

In this paper, we present low power and low data rate fully integrated super-regenerative band-pass filters for multi-band UWB system. The high RF gain, low power consumption and poor selectivity are the attractive properties of super regenerative filters for multiband UWB system. The test structure consists of four super- regenerative band-pass filters, tuned at 3.5, 4.5, 5.5 and 6.5 GHz, and has been implemented on 0.18 mum CMOS technology, active area of 1.21 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The bandwidth is adjustable between 30-to-500 MHz for data rate of lOOKb/s to IMb/s by two different quenching mechanisms. The sensitivity of -95 dBm is measured at power consumption of 1.275 mW at 1.5 V.
The Prevalence of Multiple Sleep-Onset REM Periods in a Population-Based Sample (2006)

The overall prevalence of 2 or more SOREMPs in our sample is 3.9%. Interestingly, of the variables assessed (MSLT, Epworth Sleepiness Scale, and total sleep time from nocturnal polysomnography), objective sleepiness, as determined by the MSLT, was the only measure significantly associated with 2 or more SOREMPs. Therefore, subpopulations with excessive sleepiness (eg, shift workers, young adults, patients with apnea) are likely to have a greater prevalence of SOREMPs.
Molecular characterization of the murinoglobulins. (1991)

Proteinase inhibitors of the alpha 2-macroglobulin (alpha 2M) type, although well characterized in vitro, still evade a precise description of their actual role in vivo. The main reason for this is the absence of any clinical evidence for the malfunctioning of alpha 2M in humans. Moreover, despite their ubiquitous presence in animals of very different taxa, animal models are notoriously absent in this field. With the advent of transgenic animals an important tool became available in this respect. As a first step in this direction we are analyzing at the molecular level all the members of this proteinase inhibitor family in the mouse. To retrieve related sequences we screened a mouse liver cDNA library with human alpha 2M cDNA. The sequences from two isolated clones partially coded for a protein with a high degree of sequence identity with human alpha 2M, rat alpha 2M, and rat alpha 1I3. Protein sequence data from the large and small subunits of mouse alpha 2M and of the protein isolated from mouse plasma allowed us to designate the clones as coding for murinoglobulin (MUG), an alpha 2M-related single-chain proteinase inhibitor. Rescreening resulted in the isolation of 24 clones, of which 21 were related or identical to the original MUG clones. Restriction analysis led to three groups of clones of which representative members were sequenced. Two highly homologous cDNA sequences were derived, coding for proteins that displayed the typical features of alpha 2M-type proteinase inhibitors: the overall size, the positions of a putative bait region and of the internal thiol ester, and the positional conservation of cysteine residues and putative asparagine-glycosylation sites. A third related member for which only one incomplete cDNA clone was obtained and sequenced, proved to be aberrant: the bait region contained what appeared to be an intron which escaped proper splicing. A second apparent intron was present at the 5' end of the cDNA while a frameshift mutation near the 3' end (insertion of a G) caused premature termination of the reading frame when compared to the other MUG sequences. These features were confirmed from an isolated genomic clone and extended at the genomic level: the corresponding gene, a transcriptionally weakly active pseudogene, contained the small intron but as part of a larger intron. The presence of suitable intron/exon splice sites show that a relatively small part of the intron is being introduced as an exon in the mRNA.(ABSTRACT TRUNCATED AT 400 WORDS)
Enhancing the Low-frequency Content of Vibroseis Acquisition - A Case History from the Minagish Field (2008)

Several recent advances in land seismic acquisition equipment and software have encouraged the exploration geophysicists to reconsider the potential benefits of energetic low frequencies for geophysical applications such as imaging beneath high velocity and highly absorbing formations, deep imaging, inversion of surface waves to characterize the near-surface elastic properties, velocity model estimation in geophysically complex areas and acoustic impedance inversion. We briefly review the more relevant advances in land seismic acquisition and present their application to a recently acquired 3D seismic survey over the Minagish field in Kuwait.
Developing Kansei Quality Framework for Service Business (2011)

Researchers have recently begun to consider customers' emotions as important determinants of consumers' choice. Although a number of studies have addressed the significance of service experiences and customers' emotions during consumption, few have referred to ”Kansei quality for use.” This paper is the first attempt to propose a Kansei quality framework which is truly Kansei-oriented. It adopts a broad view which considers Kansei as the positive emotion or feeling evoked by Kansei stimuli. This Kansei quality framework is a general framework constructed to represent typical Kansei stimuli that affect consumer behavio. Our focus is on how Kansei quality is integrated with usefulness, functionality, usability, and service quality, and on the features of Kansei products.
Beneficial effects of endotracheal extubation on ventricular performance. Implications for early extubation after cardiac operations. (1988)

Early endotracheal extubation has been shown to be a safe postoperative management option in patients having cardiac operations. However, few objective data exist on the response of ventricular performance to early termination of controlled ventilation. Seven patients undergoing routine elective coronary artery bypass grafting or adult repair of atrial septal defect were studied after intraoperative placement of left ventricular micromanometers, left ventricular minor axis dimension crystals, and left atrial and intrapleural pressure catheters. Physiologic data were recorded intraoperatively, during controlled mandatory ventilation in the intensive care unit, and during spontaneous respiration immediately after extubation. Extubation to spontaneous breathing was associated with a significant decline in intrapleural pressure and significant increases in left ventricular end-diastolic diameter, ejection diameter shortening, stroke work, and cardiac output. The augmented left ventricular diastolic filling seemed to result from the fall in intrapleural pressure and perhaps from normalization of right ventricular afterload. The preload recruitable stroke work relationship showed that myocardial contractility remained constant after extubation, and ventricular function improved primarily because of increased preload associated with shifting of the capacitance blood volume toward the chest. Thus endotracheal extubation enhances cardiac performance after uncomplicated cardiac surgical procedures, and by this mechanism early extubation may be clinically beneficial as a routine adjunct to postoperative care.
Modeling and compensation of antenna RF switching non-idealities in OFDM receivers (2014)

Antenna RF switches are radio frequency components used in spatial diversity systems in wireless communi-cations. In this paper, we investigate the transient effects of the antenna RF switching on the receiver front-end. We show experimentally that the duration of this effect can be significant compared to an OFDM (Orthogonal Frequency Division Multiplexing) guard period used in wireless systems. A simple memoryless time-varying model of the antenna is then developed. After quantifying the performance degradation in an OFDM system caused by the RF switching, a digital compensator to minimize this performance degradation is presented.
Trends in electronic engineering (1948)

The field of electronics may be divided into three segments: entertainment and education, communications, and industrial applications. Developments since the war in each of these areas of activity have been notable, but of particular interest is the rapid progress which has been made in the largest division of the field, broadcasting, and emphasis is placed on trends in frequency modulation and television.

Reinforcing College Reading Strategies in the Library Classroom (2013)

How can schools get college students to write papers using more scholarly texts? This problem became quite clear to us because of an incident one of this article’s authors, Richard, witnessed during his MLIS internship, team teaching a twoweek introductory library course to freshmen at a California State University. Already an English Composition instructor trained in Rhetorical Theory, Richard worked closely with his mentor librarian during this internship to design curriculum that would help students to see the value of scholarly journals. The lecture went smoothly, and students seemed to understand how to get to these scholarly texts and how the sources would deepen their research and impress their professors. Students saw the actual physical journals and how articles are digitally represented within databases. At the end of the activity, Richard asked if anyone had questions. A student, seated at the front, opened up one of the journals, pointed at the page and said, “I have a question: I can’t read this.”
Elongation factor-1α is an overexpressed actin binding protein in metastatic rat mammary adenocarcinoma (1996)

Overexpression of elongation factor-1 alpha (EF1 alpha) mRNA has been correlated with increased metastatic potential in mammary adenocarcinoma; however, this relationship was not explored at the level of protein expression. As EF1 alpha has been shown in other cell types to be a component of the actin cytoskeleton, a likely effector in metastasis, the actin binding activity of EF1 alpha from metastatic and nonmetastatic rat breast tumors and cell lines was investigated. We have shown that EF1 alpha protein is overexpressed in metastatic compared to nonmetastatic cells and whole tumors. Similarly to other EF1 alpha s, both types of tumor EF1 alpha bind to F-actin, but EF1 alpha from metastatic cells has a reduced affinity for actin. In addition, there is a high correlation between the intracellular distribution of filamentous actin and EF1 alpha in those cytoskeletal structures thought to be important for supporting the cellular motility required for metastasis. Following stimulation with EGF, there is a parallel increase in the amount of F-actin and EF1 alpha associated with the cytoskeleton. The response to EGF can be blocked with cytochalasin D indicating that the binding of EF1 alpha to the cytoskeleton is mediated by F-actin. We propose that a weakened association of EF1 alpha with actin may be related to the metastatic process via an altered organization of the actin cytoskeleton and the differential translation of mRNAs associated with the cytoskeleton.
COMET: A Neural Framework for MT Evaluation (2020)

We present COMET, a neural framework for training multilingual machine translation evaluation models which obtains new state-of-theart levels of correlation with human judgements. Our framework leverages recent breakthroughs in cross-lingual pretrained language modeling resulting in highly multilingual and adaptable MT evaluation models that exploit information from both the source input and a target-language reference translation in order to more accurately predict MT quality. To showcase our framework, we train three models with different types of human judgements: Direct Assessments, Human-mediated Translation Edit Rate and Multidimensional Quality Metrics. Our models achieve new state-ofthe-art performance on the WMT 2019 Metrics shared task and demonstrate robustness to high-performing systems.

<i>CHD8</i> regulates neurodevelopmental pathways associated with autism spectrum disorder in neural progenitors (2014)

Truncating mutations of chromodomain helicase DNA-binding protein 8 (CHD8), and of many other genes with diverse functions, are strong-effect risk factors for autism spectrum disorder (ASD), suggesting multiple mechanisms of pathogenesis. We explored the transcriptional networks that CHD8 regulates in neural progenitor cells (NPCs) by reducing its expression and then integrating transcriptome sequencing (RNA sequencing) with genome-wide CHD8 binding (ChIP sequencing). Suppressing CHD8 to levels comparable with the loss of a single allele caused altered expression of 1,756 genes, 64.9% of which were up-regulated. CHD8 showed widespread binding to chromatin, with 7,324 replicated sites that marked 5,658 genes. Integration of these data suggests that a limited array of direct regulatory effects of CHD8 produced a much larger network of secondary expression changes. Genes indirectly down-regulated (i.e., without CHD8-binding sites) reflect pathways involved in brain development, including synapse formation, neuron differentiation, cell adhesion, and axon guidance, whereas CHD8-bound genes are strongly associated with chromatin modification and transcriptional regulation. Genes associated with ASD were strongly enriched among indirectly down-regulated loci (P < 10(-8)) and CHD8-bound genes (P = 0.0043), which align with previously identified coexpression modules during fetal development. We also find an intriguing enrichment of cancer-related gene sets among CHD8-bound genes (P < 10(-10)). In vivo suppression of chd8 in zebrafish produced macrocephaly comparable to that of humans with inactivating mutations. These data indicate that heterozygous disruption of CHD8 precipitates a network of gene-expression changes involved in neurodevelopmental pathways in which many ASD-associated genes may converge on shared mechanisms of pathogenesis.

PP.15.04 (2015)

Objective: Although many papers reported that the occurrence of cardiovascular disease (CVD) increased after disaster, there is no report about specific method for the control of risk for CVD after disaster. Design and method: We have begun to implement the web-based Disaster Cardiovascular Prevention (DCAP) network in the survivors of the Great East Japan Earthquake (March 2011). We enrolled and followed up 237 patients in DCAP system to control disaster hypertension in Minamisanriku-town. Results: The average home BP was 151.5 ± 19.9/ 87.1 ± 10.2 mmHg on May 2011. The prevalence of uncontrolled hypertension (>135/85 mmHg) was 54.3%. Interindividual BP during winter of the first year disaster occurred (December 2011) tended to be lowerthan that of summer in the same year (August, 2011) (135.7 ± 12.5/78.7 ± 9.7 mmHg vs 138.6 ± 16.4/79.7 ± 11.0 mmHg, P = 0.074 for SBP, P = 0.368 for DBP). In the next year, interindividual BP on November 2012 was significantly higher than that of summer in the same year (August 2012) (129.3 ± 10.7/ 76.3 ± 10.2 mmHg vs 122.7 ± 9.5/72.4 ± 9.3 mmHg, P < 0.001 for SBP, P < 0.001 for DBP). The monthly average BP following to November, 2012 did not increase. The average home BP at final follow up in this study was 124.0 ± 8.2/ 73.3 ± 9.5 mmHg and the prevalence of uncontrolled hypertension (>135/85mmHg) was 3.2% on June 2013. Conclusions: DCAP system could provide the management of disaster hypertension and strict BP control in the disaster area.
Planar Double-Heterostructure GaAlAs LED's Packaged for Fiber Optics (1980)

A light-emitting diode (LED) design is described which incorporates the quantum efficiency advantages of a double heterostructure (DH) without the critical processing techniques required for Burrus diodes and DH lasers. A planar process is employed which yields internal quantum efficiencies as high as 100 percent and very rugged LED chips, comparable with most high-volume LED's manufactured in the industry. The packaging concept used for the LED allows a pluggable fiber-optic interface with generous mechanical alignment tolerances and provides a hermetic environment for the LED.
