The article refers to the technique of biomagnetical separation (BS) of mRNA using "Dynabeads mRNA DIRECT". After a brief survey of RNA isolation methods authors describe a general procedure of BS as well as its concrete application for mRNA isolation from bronchoalveolar cells. Authors report results of specific experiments to assess the efficiency and accuracy of mRNA isolation by BS. The app...
The position of the base station (BS) in wireless sensor networks (WSNs) has a significant impact on network lifetime. This paper suggests a mobile BS positioning algorithm for clusterbased WSNs, which considers both the location and the remaining energy level of the cluster heads in the network and evaluate the performance of the algorithm under different values of network sizes, including 100...
Abstract: Due to the continuous increase in data demanded by end-users, an energy-efficient base station (BS) is a vital topic of interest that would not only result in a substantial economic impact on service providers, but would also reduce the carbon footprint of operating a network. In this regard, we propose the structure and systematic operation of a BS with a large-scale (LS) antenna sys...
طراحی شبکه زنجیره تأمین برگشتی با هدف مدیریت کارای جریان محصولات برگشتی یکی از موضوعات مهم در مدیریت زنجیره تأمین است. تعیین قیمت محصولات برگشتی که خود می تواند تحت تأثیر عوامل متفاوتی همچون کیفیت محصولات باشد، تأثیر بسزایی بر تصمیم استراتژیک طراحی شبکه زنجیره تأمین خواهد داشت. در این مقاله، یک مدل ریاضی جامع برای طراحی شبکه زنجیره تأمین چندسطحی قیمت گذاری با قیمت گذاری پویای محصولات برگشتی تاب...
In this paper, we introduce an extension for the Birnbaum-Saunders (BS) distribution based on the modified slash (MS) distribution proposed by [12]. This new family of BS type distributions is obtained by replacing the usual normal distribution with the quotient of two independent random variables, one being a normal distribution in the numerator and the power of a exponential of parameter equa...
