In this paper, we aim to investigate the problem of estimating genetic correlation between two traits. Instead making assumptions about distribution effect sizes factors, propose use a high-dimensional linear model relate trait factors. To estimate correlation, develop generic strategy that combines sparse penalization methods and multiple sample splitting approaches. The final is determined by...

In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

Background & Aims: Substance abuse may have different effects on multiple sclerosis. Till now, studies on substance abuse and its correlation with psychopathology, type and severity of multiple sclerosis are limited. We conducted this study to evaluate the psychopathology of patients with multiple sclerosis with and without substance abuse. Methods: In this case-control, cross-sectional study p...

introduction: multiple sclerosis is a chronic inflammatory disease of central nervous system. the etiology of ms is slightly known, but genetic and environmental factors are reported. vitamin d regulates gene expression and affects target cell functions. the aim of this study was to investigate the expression variation of il-2 and il-4 genes under vitamin d supplementation in patients with mult...

Background: Magnetic resonance imaging (MRI) has improved the diagnosis and management of patients with multiple sclerosis (MS). Montreal Cognitive Assessment (MoCA) is a brief, sensitive test that has been recommended by National Institute of Neurological Diseases and Stroke and Canadian Stroke Network (NINDS-CSN) as a reliable tool to detect mild cognitive impairments. This study aimed to eva...
