Brain drain or human capital flight is a large emigration of individuals with technical skills or knowledge, normally due to conflict, lack of opportunity, political instability, or health risks. A brain drain is usually regarded as an economic cost, since emigrants usually take with them the fraction of value of their training sponsored by the government. It is a parallel of capital flight whi...
Among multi-gate field effect transistor (FET) structures, FinFET has better short channel control and ease of manufacturability when compared to other conventional bulk devices. The radio frequency (RF) performance of FinFET is affected by gate-controlled parameters such as transconductance, output conductance, and total gate capacitance. In recent years, high-k spacer dielectric materials for...
In this work, a lightly doped drain and source CNTFET with a linear channel impurity halo is proposed and the effect of linear halo slope variation on ON current, ON–OFF current ratio, leakage current, power–delay product (PDP) and cutoff frequency has been investigated. Proposed linear halo lightly doped drain and source CNTFETs has been simulated using non equilibrium Green’...
We report on non resonant detection of sub-terahertz radiation (148-353 GHz) using strained silicon modulation field effect transistor with different gate lengths. The devices were excited at room temperature by a Backward Wave Oscillator (BWO) source. Enhancement of the photoresponse signal by drain-to-source bias was observed. Increasing drain-to-source voltage leads to asymmetry between the ...
With their application as seed coatings, the use of neonicotinoid insecticides increased dramatically during the last decade. They are now frequently detected in aquatic ecosystems at concentrations susceptible to harm aquatic invertebrates at individual and population levels. This study intent was to document surface runoff and subsurface tile drain losses of two common neonicotinoids (thiamet...
upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...
excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. the phenomenon in soil can cause an effective stress and hence cause the shear strength of the soil to decrease considerably and large deformations to occur in the area. generally, increases in pore pressure occur in un-drained conditions. if it is formed, its consequences decrease ...
To study the recessive drain of college teachers is meaningful in practice. This paper, in perspective of psychological contract, analyzes the characteristics of psychological contracts of college teachers, the relationship between psychological contract breaches and recessive drain of college teachers, and the influencing factors of contract breaches, advancing relevant countermeasures for dea...
