IMPORTANCE Diversity initiatives have increased at US medical schools to address underrepresentation of minority faculty. OBJECTIVE To assess associations between minority faculty development programs at US medical schools and underrepresented minority faculty representation, recruitment, and promotion. DESIGN Secondary analysis of the Association of American Medical Colleges Faculty Roster...

With submicron technologies, gate delays are dominated by gate load delays rather than intrinsic gate delays. While the common approach for computing gate load delay (or total gate delay) is through delay tables (or k-factor equations), there are important methodology problems associated with the delay table approach. In this paper, we propose a gate driver model with a Thevenin equivalent circ...

Analysis of the electrostatic characteristics and the gate capacitance of typical nanostructured carbon nanotube field effect transistors (CNTFETs) were performed numerically. A previously developed parallelized electrostatic Poisson’s equation solver (PPES) is employed, coupled with a parallel adaptive mesh refinement (PAMR) to improve the numerical accuracy near the region where variation of ...

Aggressive scaling of MOS devices requires use of ultra-thin gate oxides to maintain a reasonable short channel effect and to take the advantage of higher density, high speed, lower cost etc. Such thin oxides give rise to high electric fields, resulting in considerable gate tunneling current through gate oxide in nano regime. Consequently, accurate analysis of gate tunneling current is very imp...

in this paper a novel all-optical logic nand, nor and xor gate based on nonlinear directional coupler theory is demonstrated. we use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. in other words, while a beam with 4 w/μm in power considered as logical one, the output is nand gate and if a beam w...
