In this paper, we have investigated the peristaltic flow of Williamson fluid in a curved channel. The governing equations of Williamson fluid model for curved channel are derived including the effects of curvature. The highly nonlinear partial differential equa- tions are simplified by using the wave frame transformation, long wavelength and low Reynolds number assumptions. The reduced nonlinear partial differential equation is solved analytically with the help of homotopy perturbation method. The physical features of pertinent parameters have been discussed by plotting the graphs of pressure rise, velocity profile and stream functions.

We investigate the transient behavior of an n-type double gate negative capacitance junctionless tun- nel field effect transistor （nC-JLTFET）. The structure is realized by using the work-function engineering of metal electrodes over a heavily doped n＋ silicon channel and a ferroelectric gate stack to get negative capacitance be- havior. The positive feedback in the electric dipoles of ferroelectric materials results in applied gate bias boosting. Various device transient parameters viz. transconductance, output resistance, output conductance, intrinsic gain, intrinsic gate delay, transconductance generation factor and unity gain frequency are analyzed using ac analysis of the device. To study the impact of the work-function variation of control and source gate on device performance, sensitivity analysis of the device has been carried out by varying these parameters. Simulation study reveals that it preserves inherent advantages of charge-plasma junctionless structure and exhibits improved transient behavior as well.

Cardiovascular disease represents the main cause of death in developed *** disease frequently may account for premature fatal outcomes,even in the apparently healthy young, appearing in the form of sudden and unexpected death [1]. Sudden death (SD) is defined according to commonly accepted criteria in witnessed cases as *** is a natural death that occurs within 6h of the beginning of symptoms in an apparently healthy subject or in one whose disease is not so severe that a fatal outcome would be expected [2].In cases of unwitnessed death, which is a common situation in forensic practice, this definition requires that the deceased was last seen alive and functioning normally 24 h before being found dead [3].
