Background: For the analysis of gene-environment (GxE) interactions commonly single nucleotide polymorphisms (SNPs) are used to characterize genetic susceptibility, an approach that mostly lacks power and has poor reproducibility. One promising approach to overcome this problem might be the use of weighted genetic risk scores (GRS), which are defined as weighted sums of risk alleles of gene var...
Abstract Introduction The new SCORE2 provides risk estimates for the combined outcome of fatal and non-fatal cardiovascular disease (CVD) events, in contrast with SCORE's use CVD mortality only. Genetic predisposition to is not considered prevention treatment. Purpose Evaluate impact adding a Risk Score (GRS) European MACE prediction estimate additional value stratification an asymptomatic Port...
هدف این پژوهش آزمون قیمت‌گذاری نقدشوندگی با تاکید بر 10 معیار متفاوت و آزمون استراتژی معاملاتی مبتنی بر نقدشوندگی و نهایتاً مقایسه آن با استراتژی مبتنی بر اندازه/ارزش است. برای این منظور نمونه‌ای متشکل از شرکت‌های پذیرفته شده در بورس اوراق بهادار تهران طی دوره زمانی 1381 تا 1393 بررسی گردید. برای نیل به هدف پژوهش از روش تحلیل پرتفوی استفاده گردیده است. نتایج حاصله حاکی از آن است که نقدشوندگی در ...
We compare the evolution of spectral shape with luminosity in GRS 1915+105 with that of ‘normal’ black holes. The pathological time variability of GRS 1915+105 does not indicate that it belongs in a different class to all the other objects. At comparable fraction of Eddington luminosity its spectra and (more importantly) time variability behaviour are similar to that seen in the ‘normal’ black ...
Galois hulls of linear codes have important applications in quantum coding theory. In this paper, we construct some new classes (extended) generalized Reed-Solomon (GRS) with arbitrary dimensions. We also propose a general method on constructing GRS dimensions from special Euclidean orthogonal codes. Finally, several families entanglement-assisted error-correcting (EAQECCs) and MDS EAQECCs by u...
Grammatical relationships (GRs) form an important level of natural language processing, but di erent sets of GRs are useful for di erent purposes. Therefore, one may often only have time to obtain a small training corpus with the desired GR annotations. To boost the performance from using such a small training corpus on a transformation rule learner, we use existing systems that nd related type...
The newest members of scientific communities, namely graduate students and postdocs, face unique challenges in their careers as scientists. In order to address these challenges, several of the Gordon Research Conferences (GRCs) have extended their meetings to include a two-day pre-meeting called a Gordon Research Seminar (GRS). Following the Gordon tradition of bringing the scientific community...
The RXTE observations of GRS 1915+105 have given a new impulse to the study of spectral and timing properties of the X-ray emission of black hole candidates. At variance with any other known source, GRS 1915+105 shows dramatic changes on time scales as short as a tenth of a second. These changes are associated to marked spectral changes which have been interpreted as changes of the observable i...
The first images of Jupiter, Io, Europa, and Ganymede from the Galileo spacecraft reveal new information about Jupiter's Great Red Spot (GRS) and the surfaces of the Galilean satellites. Features similar to clusters of thunderstorms were found in the GRS. Nearby wave structures suggest that the GRS may be a shallow atmospheric feature. Changes in surface color and plume distribution indicate di...
INTRODUCTION We hypothesized that, like apolipoprotein E (APOE), other late-onset Alzheimer's disease (LOAD) genetic susceptibility loci predict mortality. METHODS We used a weighted genetic risk score (GRS) from 21 non-APOE LOAD risk variants to predict survival in the Adult Changes in Thought and the Health and Retirement Studies. We meta-analyzed hazard ratios and examined models adjusted ...
