A sectorial scheme of gate-all-around field effect transistor with improved electrical characteristics

Reliability and controllability for a new scheme of gate-all-around field effect transistor (GAA-FET) with a silicon channel utilizing a sectorial cross section is evaluated in terms of Ion/Ioff current ratio, transconductance, subthreshold slope, threshold voltage roll-off, and drain induced barrier lowering (DIBL). In addition, the scaling behavior of electronic figures of merit is comprehensively studied with the aid of physical simulations. The electrical characteristic of proposed structure is compared with a circular GAA-FET, which is previously calibrated with an IBM sample at the 22 nm channel length using 3D-TCAD simulations. Our simulation results show that sectorial cross section GAA-FET is a superior structure for controlling short channel effects (SCEs) and to obtain better performance compared to conventional circular cross section counterpart

The effects of propolis on pro-oxidant–antioxidant balance, glycemic control, and quality of life in chronic kidney disease: a randomized, double-blind, placebo-controlled trial

Abstract Chronic kidney disease (CKD) is a progressive kidney damage with an increasing prevalence. Some evidence suggests that propolis as a novel antioxidant, anti-inflammatory, and immunomodulatory agent may have beneficial effects in CKD. The aim of this study was to evaluate the efficacy of propolis on some kidney function parameters, pro-oxidant–antioxidant balance (PAB), glycemic status, quality of life, and blood pressure (BP) in patients with CKD. In this study, 44 patients with CKD were randomly assigned to receive propolis capsules at a dose of 250 mg daily or placebo for three months. Of 44 randomized individuals, 35 completed the trial. At the end of the intervention (end of month three), improvement in some dimensions of health-related quality of life (HRQoL) (derived from Kidney Disease and Quality of Life Short-Form (KDQOL- $${\mathrm{SF}}^{\mathrm{TM}}$$ SF TM , v. 1.3) questionnaire) were significantly higher in the propolis group than the placebo group, even after adjustment for baseline values, present of diabetes, and age (P  0.05). No serious adverse events were reported throughout the study. Propolis supplementation may improve the HRQoL of CKD patients. More studies are needed to validate the adjunct use of propolis for metabolic control of CKD patients
