Hybrid Beamforming in Massive MIMO for Next-Generation Communication Technology.

Hybrid beamforming is a viable method for lowering the complexity and expense of massive multiple-input multiple-output systems while achieving high data rates on track with digital beamforming. To this end, the purpose of the research reported in this paper is to assess the effectiveness of the three architectural beamforming techniques (Analog, Digital, and Hybrid beamforming) in massive multiple-input multiple-output systems, especially hybrid beamforming. In hybrid beamforming, the antennas are connected to a single radio frequency chain, unlike digital beamforming, where each antenna has a separate radio frequency chain.

Comparison of metformin and pioglitazone in achieving sustained virological response in chronic hepatitis C patients with insulin resistance: A quasi-experimental study.

Objective: To compare metformin and pioglitazone with standard interferon and ribavirin in achieving sustained virological response in chronic hepatitis C patients.

Methods: This quasi-experimental, comparative, interventional study was conducted at Mayo Hospital, Lahore, Pakistan, from January 2015 to March 2016, and comprised chronic hepatitis C patients who had insulin resistance. The patients were divided evenly in three groups.

Effect of Vitamin D supplementation on reduction in levels of HbA1 in patients recently diagnosed with type 2 Diabetes Mellitus having asymptomatic Vitamin D deficiency.

Objective: To study the effect of Vitamin D supplementation on reduction in level of HbA1 in patients recently diagnosed with diabetes mellitus Type II having asymptomatic Vitamin D deficiency.

Methods: This randomized control trial was conducted at East Medical Ward Mayo Hospital Lahore for 6 months from January 01 2016 to June 30, 2016. 114 Patients were included through non probability purposive sampling technique.

Investigating the effect of anxiety sensitivity, gender and negative interpretative bias on the perception of chest pain.

Research suggests that anxiety sensitivity may be an important component in the negative response to pain sensations, especially those with cardiopulmonary origin. Furthermore, there is experimental evidence to suggest that such effects may be stronger in women than men. The primary aim of the current investigation was to determine the relative roles that anxiety sensitivity and gender have on the pain reports of patients referred to a hospital clinic with chest pain.
