The MRC Patulin trial1 was undertaken in 1943–1944 to investigate a proposed remedy for the common cold. Only a few clinical trials took place before the second world war and they often had serious defects of planning or execution. The Patulin trial, it is claimed, was the first to meet the rigorous requirements for a scientifically acceptable trial with concurrent controls, as set out original...
در این مقاله، آشکارساز مادون قرمز میکروکانتیلیور با حساسیت بالا و بدون نیاز به خنک ساز، طراحی و شبیهسازی شده است. این آشکارساز شامل، ناحیه جاذب، نواحی دو ماده ای و ایزوله و ستونهای نگهدارنده است. ساختار آن معلق و به صورت دو لایهای از جنس دی اکسید سیلیکون (sio2) به ضخامت µm1 و آلومینیوم (al) به ضخامت nm200 است. در این آشکارساز، میزان جذب ir و میزان خمش با طراحی ناحیه جاذب به صورت دو ماده ای ...

background and aims: adventitious agents, especially viral agents are among the most important concerns in viral vaccines. viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. in this study, adventitious ...
BACKGROUND Despite various culotte-based stenting techniques available clinically, the optimal one remains undetermined. The study aimed to test whether ex vivo mono-ring culotte stenting (MRC) was technically feasible and superior to mini culotte stenting (MCS) in treatment of coronary bifurcation lesions. METHODS Mono-ring culotte stenting was characterized by ex vivo wiring of the most pro...
There has been extensive research on large scale multi-user multiple-input multiple-output (MUMIMO) systems recently. Researchers have shown that there are great opportunities in this area, however, there are many obstacles in the way to achieve full potential of using large number of receive antennas. One of the main issues, which will be investigated thoroughly in this paper, is timing asynch...
In this paper we study the MapReduce Class (MRC) defined by Karloff et al., which is a formal complexity-theoretic model of MapReduce. We show that constant-round MRC computations can decide regular languages and simulate sublogarithmic space-bounded Turing machines. In addition, we prove hierarchy theorems for MRC under certain complexity-theoretic assumptions. These theorems show that suffici...

This paper analyses the outage probability and average bit error rate (ABER) of a multiuser Transmit Antenna Selection/Maximal-ratio combining (TAS/MRC) system over equally correlated η-μ fading channels. In TAS/MRC system the best antenna, based on channel state information (CSI) is used for information transmission and MRC is performed in the receiver. The expressions of PDF for SNR of the sy...
We examine the problem of jointly selecting the number of components and variables in finite mixture regression models. We find that the Akaike information criterion is unsatisfactory for this purpose because it overestimates the number of components, which in turn results in incorrect variables being retained in the model. Therefore, we derive a new information criterion, the mixture regressio...
