In this paper we study the feasibility of design/fabrication a vertical trench 4H-SiC Junction Field Effect Transistor (JFET), assuming realistic constraints depth P+ implantation. The doping profile is obtained using Monte Carlo implantation simulation. calculation used drift-diffusion approach. JFET aims to achieve threshold voltage of-3V. We found that constraint in concomitance with propose...

Localization-based super-resolution microscopy enables imaging of biological structures with sub-diffraction-limited accuracy, but generally requires extended acquisition time. Consequently, stage drift often limits the spatial precision. Previously, we reported a simple method to correct for this by creating an array of 1 μm3 fiducial markers, every ~8 μm, on the coverslip, using UV-nanoimprin...

There is much current interest in modelling suspensions of algae and other microorganisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispersion theory, we develop a population-level swimming-advection-diffusion model for suspensions of micro-organisms in a vertical pipe flow. In particular, a combination of gravitational and viscous t...

This paper addresses the problem of optimal alignment of non-rigid surfaces from multi-view video observations to obtain a temporally consistent representation. Conventional non-rigid surface tracking performs frame-to-frame alignment which is subject to the accumulation of errors resulting in a drift over time. Recently, non-sequential tracking approaches have been introduced which re-order th...

In this appendix we collect and describe mathematical results for first passage, boundaryless, and reflecting-boundary drift diffusion problems. We consider both diffusion and OrnsteinUhlenbeck (O-U) models. The main tools are drawn from applied probability, the theory of stochastic ordinary differential equations, and classical perturbation and asymptotic methods. Here we focus on continuous m...

Single-layer atom or vacancy clusters in the presence of electromigration are studied theoretically assuming an isotropic medium. A variety of distinctive behaviors distinguish the response in the three standard limiting cases of periphery diffusion ~PD!, terrace diffusion, and evaporation-condensation. A general model provides power laws describing the size dependence of the drift velocity in ...

‎We firstly prove the completeness of the category of crossed modules in a modified category of interest‎. ‎Afterwards‎, ‎we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows‎. ‎These constructions unify many corresponding results for the cases of groups‎, ‎commutative algebras and can also be adapted to ...

optimization of structures for minimum weight has become important in the recent designs. in this study, a genetic optimization algorithm for weight minimization of steel frames has been used. the genetic algorithm is an optimization and search technique based on the principles of genetics and natural selection. constraints regarding material strength and serviceability are taken from “aisc cod...

the present study assesses the seismic performance of steel moment resisting frames (smfs) retrofitted with different bracing systems. two structural configurations were utilized: ordinary concentrically braces (ocbfs), buckling-restrained braces (brbfs). a 7-story and 18-story steel perimeter smfs were designed with insufficient lateral stiffness to satisfy code drift limitations in high seism...
