Ginzburg-Landau form description for steps on creep curves
We consider the model proposed earlier by us for explaining the phenomenon of jumps on creep curves[1]. The model consists of three types of dislocations namely the mobile, the immobile and those with clouds o...

Optimal barrier subdivision for Kramers’ escape rate
We examine the effect of subdividing the potential barrier along the reaction coordinate on Kramers’ escape rate for a model potential. Using the known supersymmetric potential approach, we show the existence ...

Model-dependent nature of blowtorch effect on the escape and equilibration rates
We analyze the relaxation behavior of a bistable system when the background temperature profile is inhomogeneous due to the presence of a localized hot region (blowtorch) on one side of the potential barrier. ...

Current, maximum power and optimized efficiency of a Brownian heat engine
A microscopic heat engine is modeled as a Brownian particle in a sawtooth potential (with load) moving through a highly viscous medium driven by the thermal kick it gets from alternately placed hot and cold he...

Growth of germanium–carbide thin film on crystal substrate
The formation of germanium-carbide in crystalline germanium substrate is studied using the perturbed γ–γ angular correlation (PAC) method. The growth of Ge–C micro-crystalline system in the host matrix was obs...

Stochastic resonance of charge carriers diffusing in a nonhomogeneous medium with nonhomogeneous temperature
We investigate the dynamics of charge carriers hop** from one trap to the other trap along an n-type semiconductor layer consisting of a spatially nonhomogeneous trap distribution of depth Φ assisted by thermal...

Impurity diffusion in a harmonic potential and nonhomogeneous temperature
We propose different ways of manipulating the dispersion of impurities along a semiconductor layer during heat treatment. The impurities undergo a random walk assisted by a nonlinear harmonic potential and non...

Open AccessWater accessibility impact on girl and women’s participation in education and other development activities: the case of Wuchale and Jidda Woreda, Ethiopia
Ethiopia has huge water resource potential. However, it contributed little to access to clean and safe drinking water supply and socio-economic development. The objective of this study was to assess water acce...

Thermally activated diffusion of impurities along a semiconductor layer
The dynamics of impurities that walk along a semiconductor layer assisted by thermal noise strength and quartic potential is explored analytically and numerically. Applying two cold spots in the vicinity of th...

Noise-formed triple-well potential and stochastic resonance of charge carriers
We study the thermal dynamics of charge carriers jum** across potential traps in a one-dimensional semiconductor layer. The potential traps are denser at the middle layer and decay exponentially when moving ...

A computational investigation of cis-gene regulation in evolution
In biological processes involving gene networks, genes regulate other genes that determine the phenotypic traits. Gene regulation plays an important role in evolutionary dynamics. In a genetic algorithm, a tra...
