A unified, closed form analytical drain current model for partially and fully depleted SOS MOSFETs was investigated. The analytical model was developed using first order principles of operation of the device and basic explanation of the physical constraints responsible for hot carriers effects. The approach solved for the channel field to find closed form solutions for the critical voltages giv...

This article presents the exact solutions of the velocity and temperature fields for a steady fully developed magnetohydrodynamic flow of a viscous incompressible and electrically conducting fluid between two horizontal concentric cylinders. Our study focuses on the influence of the Hartmann number, Brinkman number, Péclet number and inner radius on the fluid temperature field, entropy generati...

a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...

Voltage-dependent potassium channels (Kv) are homotetramers composed of four voltage sensors and one pore domain. Because of high-level structural flexibility, the first mammalian Kv structure, Kv1.2 at 2.9 A, has about 37% molecular mass of the transmembrane portion not resolved. In this study, by applying a novel normal-mode-based X-ray crystallographic refinement method to the original diffr...

embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...

this paper presents the results of numerical simulations of the laminar and turbulent flows inside diverging channels using random vortex methods (rvm). random vortex method is a mesh-free method which solves unsteady vorticity equation instead of solving navier-stokes equations directly to determine the velocity field. in this paper, the velocity potential, which is used as the initial conditi...
