We introduce a coe cient update procedure into existing batch and online dictionary learning algorithms. We rst propose an algorithm which is a coe cient updated version of the Method of Optimal Directions (MOD) dictionary learning algorithm (DLA). The MOD algorithm with coe cient updates presents a computationally expensive dictionary learning iteration with high convergence rate. Secondly, we...
background: restless legs syndrome (rls) is the most common movement disorder in pregnancy, which can be idiopathic or secondary. there are limited comparative data regarding these two forms of rls. the aim of this study was to compare clinical features of idiopathic and secondary rls in pregnant women. methods: over a period of 3 months, 443 women who admitted for delivery in t...
background and objective : restless legs syndrome (rls) is a sleep disorder with an association to sleep quality. we investigated the sleep quality in patients with rls among health-care workers with or without shift work. materials and methods : all female health-care workers (n = 540) in four educational hospitals were enrolled in this cross-sectional study. international rls study group (irl...
We investigate the properties of local HI-selected galaxies detected in blind radio surveys by using semi-analytic galaxy formation models in the hierarchical structure formation scenario. By drawing a detailed comparison between the properties of the HI-selected galaxies and the quasar absorption systems, we investigate a link between the local galaxy population and the quasar absorption syste...
The present study aimed to detect the role of 3, 4-dihydroxyl-phenyl lactic acid (DLA) during ischemia/reperfusion (I/R) induced myocardial injury with emphasis on the underlying mechanism of DLA antioxidant. Male Spragu-Dawley (SD) rats were subjected to left descending artery occlusion followed by reperfusion. Treatment with DLA ameliorated myocardial structure and function disorder, blunted ...
رشد فناوری و افزایش تصاعدی اطلاعات نیاز به حجم ذخیرهسازی بیشتر دادههای اطلاعاتی گوناگون را افزایش داده است. در این راستا فشردهسازی تصویر بهعنوان ابزاری کارآمد جهت کاهش افزونگی و صرفهجویی در حجم ذخیرهسازی و کاهش پهنای باند انتقالی دادههای تصویری به کار میآید. هنگامیکه فشردهسازی یک دسته یا خانواده از تصاویر، مانند پایگاه داده تصاویر چهره یک سازمان یا مؤسسه یا پایگاه داده MRI یک بیمارستا...

BACKGROUND Substantially elevated blood D-lactate (DLA) concentrations are associated with neurocardiac toxicity in humans and animals. The neurological symptoms are similar to inherited or acquired abnormalities of pyruvate metabolism. We hypothesized that DLA interferes with mitochondrial utilization of L-lactate and pyruvate in brain and heart. METHODS Respiration rates in rat brain, heart...
We present new spectroscopic observations of the quasar Q2059−360, confirming the existence of an emission feature within the Damped Lyman Alpha (DLA) absorption trough. By observing also at slit positions offset from the quasar, we show that the emission is spatially extended by at least a few arcseconds, and hence confirm that the feature seen must be due to emission rather than unusual absor...
