Novel Modular Adder Based on Thermometer Coding for Residue Number Systems Applications

Abstract: Residue Number Systems (RNS) was an efficient substitute to Positional Number Systems. Now-a-days RNS used in different fields in technology like Communications, Digital Signal Processing (DSP), Digital Image Processing (DIP), Cryptography, Network Security, Internet of Things (IoT), Embedded Systems (ES), etc., because it provides an efficient computational system in terms of speed, power, energy, area, etc. Modular Adder is an important element in RNS systems, like forward converters, reverse converters, modulo channels, etc. One of RNS applications is low power embedded systems where the dynamic range is less or moderate, Thermometer Coding (TC) is used. In this paper, a new Thermometer Coding based modular adder was proposed. This design has been simulated using NC Launch – Encounter tool in Cadence.

Experimental evidences of methanolic extraction of Cressa cretica Linn. on alloxan induced hyperglycemic Wistar rats

Abstract: Summary In the present study, the physico-metabolic parameters measured were: serum insulin, serum lipid profile, serum biomarker enzymes and anti-oxidant enzymes, total cholesterol, HDL cholesterol, triglycerides, LDL cholesterol, VLDL cholesterol, total proteins, alanine transaminase (ALT), aspartate transaminase (AST), creatinine, insulin assay (RIA), for in vivo anti-oxidant activity of MECC was measured in liver tissue homogenate (LTH) by malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD) enzymes and histopathological examination of pancreas were also observed. Previously, the methonolic extract of Cressa cretica Linn. effect on alloxan induced hyperglycemic Wistar rats was proved by taking the parameters like body weight, blood glucose, glycogen content in liver and muscle. Oral administration of MECC (200 mg/kg, 400 mg/kg) for 28 days exhibited a significant reduction in blood glucose, serum ALT, AST, CR, lipid profile and hepatic MDA levels. The improvement of hepatic enzymes such as GSH, serum TP, HDL, insulin levels were also observed. The results of this work also suggest that MECC may possess anti-hyperglycemic and anti-oxidant property.
