Heart rate variability (HRV) refers to the beat-to-beat fluctuations in cardiac rhythm occurring due modulation of pacemaker (sinoatrial node) activity heart by sympathetic and parasympathetic branches autonomic nervous system. Nowadays, cardiovascular diseases their risk factors are increasingly at a younger age (children adolescents) recording HRV them will help us identify derangement earlier. However, be used clinically, normative data has established this group considering other major...

We demonstrate that localized gain induces chirped double-kink, fractional-transform, bell and kink-type solitons in a nonlinear optical medium the presence of two-photon absorption (TPA). have seen by modulating properties one can control width double-kink solitons. It is shown chirp associated with directly proportional to intensity wave. further investigated variation TPA coefficient found transversally its amplitude value coefficient.

Abstract We present a detailed analysis for the existence of dark and bright solitary waves as also fractional-transform solutions in nonlinear Schrödinger equation model competing cubic–quintic higher-order nonlinearities with dispersive permittivity permeability. Parameter domains are delineated which these ultrashort optical pulses exist negative-index materials (NIMs). For example, solitons case normal second-order dispersion, anomalous third-order self-focusing Kerr nonlinearity,...

Suicide patterns and rates differ in various populations cultures. It has been reported that developing countries have lower suicide rates, possibly because of a level environmental stress but the Indians very high rate (Elfawal, 1999). The choice method used to commit depends on availability means, knowledge about lethal effectiveness, victim's motivation intent. present work was designed investigate different methods self-destruction, age gender susceptibility suicide, groups particularly...
