Nitric Oxide & Inducible Nitric Oxide Synthase: A Glimpse on Biological Role
Abstract: Nitric oxide (NO) is a multifunctional molecule having numerous physiological and pathophysiological functions. It is synthesized from L-arginine by three different isoforms of nitric oxide synthase (NOS), which are categorized into two subtypes; constitutive nitric oxide synthase (cNOS) and inducible nitric oxide synthase (iNOS). Constitutive nitric oxide synthase (cNOS) is constitutively expressed in the cells, while inducible nitric oxide synthase (iNOS) is expressed within several hours after the stimulation of …

Logarithmic Companding using Firefly Algorithm for PAPR Reduction in OFDM System
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission method developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. However OFDM is handicapped with a major problem of high peak-to-average power ratio (PAPR), which gives rise to non-linear distortion, inter-symbol interference and out-of-band radiation. Several PAPR reduction techniques have been devised over the last few decades in …
