in this paper, different input-oriented ratio-based dea (dea-r-i) models are proposed. by presenting the envelopment-additive-enhanced russell model based on the dea-r-i form, each decision making unit is evaluated and its efficiency score is calculated. also, by presenting the central resource allocation model based on the dea-r-i form, a suitable benchmark for all dmus is proposed by solving ...
Low threshold Ca2+ currents mediated by T-type channels underlie burst spike activities of relay neurons in the thalamus. We have previously reported that knock-out mice for T-type channels show an enhanced nociceptive response to visceral pain, accompanied by an increase in tonic spikes in the absence of burst spikes in thalamic relay neurons. These results raised a possibility that T-type cha...
The benefits of textual input enhancement in the acquisition of linguistic forms have produced mixed results in SLA literature. The present study investigates the effects of textual enhancement on adult foreign language intake of two English linguistic forms-subjunctive mood and inversion structures-to explore the role of the type of linguistic items in input enhancement studies. It also invest...

BACKGROUND AND PURPOSE Dynamic contrast-enhanced MR imaging parameters can be biased by poor measurement of the vascular input function. We have compared the diagnostic accuracy of dynamic contrast-enhanced MR imaging by using a phase-derived vascular input function and "bookend" T1 measurements with DSC MR imaging for preoperative grading of astrocytomas. MATERIALS AND METHODS This prospecti...
The efficient incoupling of light into particular fibers at large angles is essential for a multitude applications; however, this difficult to achieve with commonly used due low numerical aperture. Here, we demonstrate that optical functionalized arrays metallic nanodots show substantially improved large-angle light-collection performances multiple wavelengths. In particular, visible wavelength...
اغلب پروسس هایی که در صنایع و به خصوص صنایع شیمیایی وجود دارند ورودی و خروجی های متعددی دارند. کنترل این پروسس ها که به نام : mimo (multiple input-multiple - output) معروفند، به سادگی کنترل سیستم های تک ورودی و تک خروجی : siso (single input single output) نمی باشد. زیرا سیستم های mimo تداخلی بوده و استفاده از حلقه های متعدد به فرم معمول در اغلب موارد پاسخ های مناسبی بوجود نخواهد آورد. به همین د...
Summary In this article, a four‐port circularly polarized printed multiple‐input multiple‐output (MIMO) antenna is designed to cover Wi‐Fi/WLAN (5 GHz), Wi‐MAX (3.4–3.6), and C band applications, which consists of four trapezoidal shaped patches with microstrip feed. To achieve high isolation between the ports, elements are located orthogonally each other. The separated by placing diagonal line...
