In most existing grant-free (GF) studies, the two key tasks, namely active user detection (AUD) and payload data decoding, are handled separately. this letter, a two-step data-aided AUD scheme is proposed, initial step false alarm correction respectively. To implement step, an embedded low-density-signature (LDS) based preamble pool constructed. addition, message passing algorithm (MPA) estimat...

800x600 background: pregnancy, due to hormonal changes and body reshaping, might disturb the pregnant women’s body image and self-esteem and also increase depression susceptibility. body dissatisfaction may result in some compensating attempts, such as weight loss, for improving body shape. these behaviors could result in serious outcomes for maternal and child health. the aim of the present st...

background: previous studies on the correlation between dietary intakes and stroke have mostly focused on the dietary glycemic index (gi) of potatoes and there is no information regarding the correlation between potato consumption and risk of stroke. therefore, the aim of this study was to evaluate the correlation between potato consumption and risk of stroke in an iranian population. methods: ...

800x600 abstract: aim: the aim of this study was to investigate that the necessity of screening for celiac disease in idiopathic osteoporotic patients. background: osteopenia and osteoporosis are well-known and prevalent complications of celiac disease. however, the relative prevalence of celiac disease among osteoporotic populations is not known, and the benefit of screening for celiac disease...

Tears and false neighborhoods are the defaults that may occur when a mapping is set up. Three recent articles discuss about these risks and proposed various means to detect and avoid such penalizing situations. In the present paper we link these methods and suggest a new strategy to visualize tears and false neighborhoods on a mapping by adapting well-tried tools.

IDS are regularly evaluated by comparing their false positive and false negative rates on ROC curves. However, this mechanism generally ignores both the context within which the IDS operates and the attacker’s own ability to adapt to IDS behavior. In this paper, we propose an alternative strategy for evaluating IDS based around multiple strategies. Each strategy defines how an attacker profits ...
