In this paper we investigate the achievable rate of LOS MIMO systems that use 1-bit quantization and spatial oversampling at the receiver. We propose that by using additional antennas at the receiver, the loss incurred due to the strong limitation of the quantization can be decreased. Mutual information results show that considerable rate gains can be achieved depending on the number and arrang...

Life table method was presented as a method of choice to analyse data arising out of longitudinal studies. The method was employed to study length of stay (LOS) of psychiatric in-patients. The result obtained was compared with LOS calculated by traditional methods. The LOS was 58-60 days computed by traditional methods for the year 1985 for our centre. This was shown by the life table method as...

In this paper, the performance of uplink spectral efficiency in massive multiple input multiple output (MIMO) over spacially correlated Ricean fading channel is presented. The maximum ratio combining (MRC) receiver is employed at the base station (BS) for two different methods of channel estimation. The first method is based on pilot-assisted least minimum mean square error (LMMSE) estimation, ...

Objective: Angiotensin II (Ang II), the main product of renin-angiotensin system (RAS) has a well-known role in cardiovascular regulation. Over-production of Ang II is one of the important underlying mechanisms of hypertension. In this study, the effect of crocin on cardiovascular responses in rats with acute hypertension induced by Ang II was evaluated. Materials and methods: Rats were divided...

When a detector sensitive to the target plume IR seeker is used for tracking airborne targets, the seeker tends to follow the target hot point which is a point farther away from the target exhaust and its fuselage. In order to increase the missile effectiveness, it is necessary to modify the guidance law by adding a lead bias command. The resulting guidance is known as target adaptive guidance ...

Background: Acinetobacter baumannii is an opportunistic, aerobic, nonfermentative, Gram-negative bacterium that can cause major nosocomial infections, especially in patients hospitalized in intensive care units (ICU). Recently, A. baumannii strains have been resistant to a variety of antibiotics. Thus, it was aimed to evaluate the prevalence of A. baumannii and their resistance to the antibioti...

Implementation of point-of-care ultrasonography (POCUS)-assisted physical examination (PE) in emergency departments (EDs) was conducted in the ED of an urban tertiary teaching hospital. This study examines the effect of POCUS implementation in emergency medicine departments by using a systematic education program on image acquisition to analyze decision making.Educating staff on POCUS involved ...

Background: Neonatal sepsis is a major cause of mortality and morbidity, especially in developing countries. The goal of the present study was to determine the bacterial etiology and antibiotic sensitivity patterns of neonatal sepsis. Methods: This cross sectional study was conducted on 208 neonates admitted with clinically suspected sepsis over a period of 30 months. Sepsis was divided into ea...
