MgO Magnetic Tunnel Junction Electrical Current Sensor With Integrated Ru Thermal Sensor

Full Wheatstone bridge electrical current sensor incorporating 114 MgO-based magnetic tunnel junction elements (3 × 30 μm2) connected in series was produced for improved electrical robustness. To that end, magnetic tunnel junctions with R × A ~7 KΩ μm2 tunneling magnetoresistance of 200%, were produced. The sensor was designed with an integrated Ru thin film resistive thermal detector (RTD) for temperature drift monitoring and compensation. In order to achieve a full bridge signal, a U-shaped copper trace was placed under a printed circuit board (PCB) specifically designed for this type of device. The resulting device exhibit sensitivities of 63.9 V/Oe/A in a 75 Oe linear range biased with 1 mA current, providing a significantly advantageous alternative to AMR and GMR based bridges.
A Low THD, Low Power, High Output-Swing Time-Mode-Based Tunable Oscillator Via Digital Harmonic-Cancellation Technique

An architectural solution for designing and implementing low THD oscillators is presented. A digital harmonic-cancellation-block is used to suppress the low-frequency harmonics while a passive, inherently linear, filter is used to suppress the high-frequency ones. The proposed technique eliminates the need for typical high-Q BPF to suppress the harmonics. Thus, eradicates the effect of increasing device nonlinearities in the nanometric technologies by having pure digital solution. In addition, eliminating the need for high-Q band-pass-filter (BPF) releases the output swing from the constraints imposed by the linearity of the filter. The prototype is fabricated in 0.13 ¿m CMOS technology. Measurement results show -72 dB THD at 10 MHz along with a differential output swing of 228 mVpp. The oscillator prototype can be tuned from 5 MHz to 11 MHz with less than 4.5 dB variations in the THD. The circuit consumes 3.37 mA from 1.2 V supply at 10 MHz and occupies an area of 0.186 mm2. As the performance depends solely on the timing precision of digital signals, the proposed oscillator is considered the best time-mode-based oscillator in literature.
Optimizing RLV ascent trajectory using PSO algorithms

RLV (reusable launch vehicle) ascent-trajectory optimization is a difficult problem due to the complexity of many physical constraints and optimization cost surfaces. In this paper, a heuristic technique based on a PSO (particle swarm optimization) algorithm is used. The highly constrained nonlinear trajectory planning problem is decomposed into control parameters search problems, The algorithm is able to generate a complete and feasible ascent trajectory, given the ascent conditions, values of constraint parameters, and final conditions. Numerical simulation with a RLV model for ascent mission is presented to demonstrate the capability and effectiveness of the algorithm.
CLOSED-LOOP CARDIOVASCULAR SYSTEM MODEL AND PARTIAL HEPATECTOMY SIMULATION

The present work aims at developing a mathematical model in order to reproduce hemodynamics changes due to liver surgeries. First, a 0D closed-loop model is developed, to simulate hepatectomy and compute post-operative average values. Due to the closed loop, the surgery impact both on and from the whole circulation can be captured, including bleeding and infusion. Then, a one-dimensional artery model is implemented to improve the closed-loop model and simulate better the changes in arterial waveforms due to surgery.
A new Ontology Lookup Service at EMBL-EBI

The Ontology Lookup Service (OLS) hosted at the EMBL European Bioinformatics Institute has been providing ontology search and visualisation services for over ten years. In this time the range and diversity of ontologies has changed dramatically. One of the major shifts has been the increasing use of the W3C Web Ontology Language (OWL) for representing biomedical ontologies. The OLS has been reengineered in order to accommodate the OWL standard and provide a wider range of ontology-based services to the community.
Regional connectivity and coastal expansion: differentiating pre‐border and post‐border vectors for the invasive tunicate Styela clava

The dramatic increase in marine bio‐invasions, particularly of non‐indigenous ascidians, has highlighted the vulnerability of marine ecosystems and the productive sectors that rely on them. A critical issue in managing invasive species is determining the relative roles of ongoing introductions, versus the local movement of propagules from established source populations. Styela clava (Herdman, 1882), the Asian clubbed tunicate, once restricted to the Pacific shores of Asia and Russia, is now abundant throughout the northern and southern hemispheres and has had significant economic impact in at least one site of incursion. In 2005 S. clava was identified in New Zealand. The recent introduction of this species, coupled with its restricted distribution, provided an ideal model to compare and contrast the introduction and expansion process. In this study, the mitochondrial DNA cytochrome oxidase subunit I gene (COI) gene and 11 microsatellite markers were used to test the regional genetic structure and diversity of 318 S. clava individuals from 10 populations within New Zealand. Both markers showed significant differentiation between the northern and southern populations, indicative of minimal pre‐ or post‐border connectivity. Additional statistics further support pre‐ and post‐border differentiation among Port and Harbour populations (i.e. marinas and aquaculture farms). We conclude that New Zealand receives multiple introductions, and that the primary vector for pre‐border incursions and post‐border spread is most likely the extensive influx of recreational vessels that enter northern marinas independent of the Port. This is a timely reminder of the potential for hull‐fouling organisms to expand their range as climates change and open new pathways.
Covariate adjustment in family‐based association studies

Family‐based tests of association between a candidate locus and a disease evaluate how often a variant allele at the locus is transmitted from parents to offspring. These tests assume that in the absence of association, an affected offspring is equally likely to have inherited either one of the two homologous alleles carried by a parent. However, transmission distortion was documented in families in which the offspring are unselected for phenotype. Moreover, if offspring genotypes are associated with a risk factor for the disease, transmission distortion to affected offspring can occur in the absence of a causal relation between gene and disease risk. We discuss the appropriateness of adjusting for established risk factors when evaluating association in family‐based studies. We present methods for adjusting the transmission/disequilibrium test for risk factors when warranted, and we apply them to data on CYP19 (aromatase) genotypes in nuclear families with multiple cases of breast cancer. Simulations show that when genotypes are correlated with risk factors, the unadjusted test statistics have inflated size, while the adjusted ones do not. The covariate‐adjusted tests are less powerful than the unadjusted ones, suggesting the need to check the relationship between genotypes and known risk factors to verify that adjustment is needed. The adjusted tests are most useful for data containing a large proportion of families that lack disease‐discordant sibships, i.e., data for which multiple logistic regression of matched sibships would have little power. Software for performing the covariate‐adjusted tests is available at http://www.stanford. edu/dept/HRP/epidemiology/COVTDT. Genet. Epidemiol. © 2004 Wiley‐Liss, Inc.
Cardiac mapping and stem cell delivery for the damaged myocardium

Despite improvements in revascularization therapies, access to advanced medical facilities and community awareness of coronary artery disease, heart failure remains one of the most common and costly reasons for hospital admission in the USA. Perhaps a victim of our own success, as patients survive myocardial infarction and live longer, more live with the sequelae of damaged myocardium. As scientific and clinical focus has shifted to regenerative medicine, the promise of stem cell therapy to aid in the improvement of myocardial function has nurtured the investigation of optimal therapeutic strategies. Systemic, intracoronary, intraventricular and direct myocardial delivery of stem cells have produced mixed results. Limitations in available stem cell lines and delivery methods remain challanges to a firm foundation for future clinical success. The advent of sophisticated intracardiac electro mechanical mapping (EMM) systems and catheters equipped with injection ports represents a new horizon for stem cell delivery. This article will provide insights into intracardiac EMM for stem cell delivery for damaged myocardium and the future directions with this exciting new therapeutic approach. Heart failure affects millions of patients worldwide. The socioeconomic burden of this disease is exemplified by the fact that heart failure remains the most common reason for hospital admission in the USA [1] and cases are expected to double in the next 40 years [2]. Associated with this enormous disease burden is the extraordinary cost of treatment, estimated at US$18 billion per year [2]. The increasing prevalence of this disease is probably the result of improved pharmacological regimens and increased survival for patients after myocardial infarction [3]. Heart transplantation remains a viable option for certain patients; however, the limited pool of available donors and the relatively poor long-term survival of patients undergoing transplantation remain areas for improvement. This has spawned the development of novel invasive strategies to treat heart failure patients, including more portable, sustainable ventricularassist devices and ultrafiltration machines capable of removing large volumes of isotonic fluid through peripheral veins, permitting more advanced outpatient treatment options. Recently, increasing interest has focused on the role of regenerative medicine through the use of stem cell therapy to improve or restore damaged myocardium and enhance cardiac function. The long-held paradigm that mature cardiac myocytes are incapable of regeneration has recently been confronted by intense research focused on the role of stem cell-based therapy. The hope that postnatal cardiomyogenesis and vasculogenesis will reset or slow the morbidity and mortality burden associated with heart failure fuels this burgeoning area of research.
Utilization of a basic care and prevention package by HIV-infected persons in Uganda

Abstract Opportunistic infections are the leading cause of mortality among HIV-infected people. Several simple interventions prevent illness, prolong life, or prevent HIV transmission from HIV-infected people in Africa. These include: cotrimoxazole prophylaxis; insecticide-treated bed nets; supplies for household water treatment and safe storage; materials promoting family voluntary counselling and testing (VCT); and condoms. We provided these interventions to adults and children with HIV who were members of the AIDS Support Organization in Uganda. To evaluate use of this basic care and prevention package, we surveyed a representative sample of 112 clients of TASO in their homes. Among respondents, 95% reported taking cotrimoxazole everyday, 89% said they had slept under a bednet the night before, 65% reported current treatment of household drinking water, 89% of sexually active respondents reported using condoms, and 96% reported family use of VCT. Household observations verified that use of cotrimoxazole, bednets, and water treatment products were consistent with reported use. This evaluation suggests successful distribution and use of basic care and prevention services at an AIDS organization in Uganda.
SMART: stochastic model-checking analyzer for reliability and timing

SMART is a software package integrating logic and stochastic modeling formalisms into a single environment. Models expressed in different formalisms can be combined in the same study. To study logical behavior, both explicit and symbolic state-space generation techniques, as well as CTL model-checking algorithms, are available. To study stochastic and timing behavior, both explicit and Kronecker-based numerical solution approaches are available. Since SMART is intended as an industry and research tool, it is written in a modular way that allows for easy integration of new formalisms and solution algorithms.
Influence of Storage on the Composition Apple Juice Concentrate

The effect of storage on apple juice concentrate was determined by following changes in composition during a period of 111 days at 37°C. Results showed that storage caused an 87% loss in the total free amino acids, which was mostly due to decreases in glutamic acid, asparagine and aspartic acid. The form01 titration method was inadequate for determining the amino compounds involved in Maillard-type reactions. Sucrose was hydrolyzed under these conditions at a rate corresponding to a fist order process. The reducing sugars increased at a rate determined by the inversion of sucrose; no consumption attributable to browning reaction was detected. Reduction of organic acids was 9% while apparent phenolic compounds increased from 0.149 to 0.215 g/lOOg. A maximum accumulation of HMF was observed after 100 days of storage.
Expert opinion and cuisine reputation in the market for restaurant meals

As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators and other objective indicators in the market for restaurant meals. The empirical findings presented suggest that both individual restaurant reputation and cuisine type reputation are important. Other important factors are shown to include the quality of the restaurant wine list, the availability of private dining rooms, and whether or not there is an outdoor dining option.
Proposed novel design of silica PCF to minimizing the dispersion using OptiFDTD

Photonic crystal fiber (PCFs) are the branch of silica based optical fiber where vent to pass the air are dig into the outer region of core and these seem to be moving ahead in the direction of axis of the parent fiber . PCF have been in acquaintance since the days when research in the region of light source based on silica was on the high. Crystal fibers are available in various architectures as to allow air through the holes which were distributed. Kiser et al, was the principle investigator in earliest era of silica based fiber that made material fiber from single material and also minimized the losses. His work was further explained by Russell and his co-workers as Photonic crystal fiber (PCF). Micro-structured optical fibers(MOFs). In the presented work, I considered an air-silica lattice and demonstrate a new approach to design the formation of a core defect. For this case I have considered some variations in the diameters of different layers. Here the traditional design of PCF is omitted and a novel design of PCF is proposed using optiFDTD to minimize dispersion. Minimization of dispersion in the proposed design was not easy as I tried to minimize the dispersion value other parameters such air-hole diameter and pitch were changing with respect to each other, thus require adjustment. Finally the proposed design was achieved with minimum dispersion and required refractive index. However all the result changes have been demonstrated through the various plots and nearly zero dispersion calculation is obtained which was a desired aspects for and type of PCF. All the parameters are clearly mentioned and results are placed with all plots.
The Avalon Gardens Men’s Association: A Community Health Psychology Case Study

This article follows the development and progress of the US Department of Housing and Urban Development’s ‘Healthy and Safe Communities’ initiative as it was implemented by a community empowerment organization during a four-year community revitalization project in the aftermath of the Los Angeles riots. The author explores practical aspects of Community Health Psychology through assessing the ways in which its organizing principles were manifest in community-wide processes of individual and community change in one low-income housing project in South Central Los Angeles called Avalon Gardens. Specifically highlighted is how a group of African American and Latino men in the community created a group forum that helped foster, support and sustain an empowerment process that supported health promotion, health consciousness and significant health improvement in the community.
Impact of Different Toothpastes on the Prevention of Erosion

The aim of the present study was to test the impact of different toothpastes on the prevention of erosion. Enamel demineralization and remineralization were monitored using surface microhardness (SMH) measurements. Human enamel specimens were treated following two different procedures: (1) incubation in toothpaste slurry followed by acid softening and artificial saliva exposure; (2) acid softening followed by incubation in toothpaste slurry and artificial saliva exposure. For the control procedure, toothpaste treatment was excluded. The following toothpastes were tested: Zendium, Sensodyne Proschmelz (Pronamel), Prodent Rocket Power, Meridol and Signal active. Normalized SMH values compared to the baseline (= 1.00) after 1-hour artificial saliva exposure for procedure 1 (respectively for procedure 2) were as follows (mean: 95% CI): Sensodyne Proschmelz 0.97: 0.93, 1.00 (0.92: 0.90, 0.94), Zendium 0.97: 0.94, 1.00 (0.89: 0.83, 0.95), Meridol 0.97: 0.94, 1.00 (0.94: 0.92, 0.96), Signal active 0.94: 0.91, 0.97 (0.95: 0.91, 0.99), Prodent Rocket Power 0.92: 0.90, 0.94 (0.93: 0.89, 0.97) and control 0.91: 0.88, 0.94. Further exposure to artificial saliva for up to 4 h showed no significant improvement of SMH. Regression analyses revealed a significant impact of the applied procedure. Incubation in toothpaste slurries before the acid challenge seems to be favorable to prevent erosion. None of the tested toothpastes showed statistically significant better protection than another against an erosive attack.
Enhancing the contingency performance of HELENSÄHKÖVERKKO OY 110 KV NETWORK by optimal installation of UPFC based on Genetics Algorithm

Unified Power Flow Controller (UPFC) has a promising effect on controlling the characteristics of the power system operation. During the contingency outage cases, the transmission lines are overloaded and the buses are subjected to voltage violations. Unified Power Flow Controller (UPFC) has both shunt and series controller effect inside its frame. This option gives the UPFC the power to control the voltage profile and the transmission lines flow simultaneously. In this paper, we use the Genetics Algorithm (GA) to find the optimal location and the optimal settings of UPFC to improve the performance of the power system at the contingency of the transmission line outage. The proposed technique will be tested on the IEEE 6-bus system to show the validity of the technique. This procedure is proposed for being applied on the Finnish network, Helsinki HELENSÄHKÖVERKKO OY 110 KV NETWORK. The simulations will be achieved until operating conditions of Year 2020
Network analysis of user generated content quality in Wikipedia

Purpose – Social media platforms allow near‐unfettered creation and exchange of user generated content (UGC). Drawing from network science, the purpose of this paper is to examine whether high and low quality UGC differ in their connectivity structures in Wikipedia (which consists of interconnected user generated articles). Design/methodology/approach – Using Featured Articles as a proxy for high quality, a network analysis was undertaken of the revision history of six different language Wikipedias, to offer a network‐centric explanation for the emergence of quality in UGC.Findings – The network structure of interactions between articles and contributors plays an important role in the emergence of quality. Specifically the analysis reveals that high‐quality articles cluster in hubs that span structural holes.Research limitations/implications – The analysis does not capture the strength of interactions between articles and contributors. The implication of this limitation is that quality is viewed as a binar.
Capacitor Placement and Sizing in Distorted Distribution Systems Using Simplified Direct Search Algorithm

 Abstract—In distribution systems, shunt capacitors are added in order to reduce the total active power loss and improve the power factor. However, the installation of shunt capacitors in distorted distribution systems will amplify the harmonics distortion level, if it is not placed in a proper location with harmonics consideration. Therefore, to take into account the presence of harmonic distortion, this paper proposes a simplified direct search algorithm to determine capacitors placement and sizing in distorted distribution systems. This algorithm is connected to harmonic power flow to search the proper location and size of shunt capacitors, which can decrease the total active power loss and increase the power factor, while the total harmonic distortion does not exceed the maximum allowable harmonic distortion level at each bus. To validate the method proposed, this algorithm is tested on 13-bus radial distribution system and 34-bus radial distribution system with harmonic current injection in order of 5, 7, 11, 13, and 17.
Human immunodeficiency virus type 1 is present in the cerebrospinal fluid of a majority of infected individuals

Cerebrospinal fluid (CSF) specimens from 63 patients with different severities of human immunodeficiency virus (HIV-1) infection, including asymptomatic virus carriers, were examined for the presence of HIV-1 by using polymerase chain reaction (PCR) and virus isolation. Polyadenylated RNA, presumably associated with virus particles, was extracted and reverse transcribed, and the pol region was amplified in a nested PCR. Virus could be detected in 90% of the CSF specimens examined by PCR, and data on isolation of virus from CSF were in agreement with these figures. In fact, when several CSF specimens from the same individual were studied, HIV-1 could be isolated from 80% of the patients. The presence of the viral RNA in CSF was independent of the clinical stage of infection and of neurological symptoms. These results show that the spread of HIV-1 to the brain represents an early event during infection and occurs in the majority of asymptomatic individuals.
Sparkle: optimizing spark for large memory machines and analytics

Given the growing availability of affordable scale-up servers, our goal is to bring the performance benefits of in-memory processing on scale-up servers to an increasingly common class of data analytics applications that process small to medium size datasets (up to a few 100GBs) that can easily fit in the memory of a typical scale-up server To achieve this goal, we leverage Spark, an existing memory-centric data analytics framework with wide-spread adoption among data scientists. Bringing Spark's data analytic capabilities to a scale-up system requires rethinking the original design assumptions, which, although effective for a scale-out system, are a poor match to a scale-up system resulting in unnecessary communication and memory inefficiencies.
