Ballistic random walks in random environment at low disorder
Annals of Probability, 2004 Published at http://dx.doi.org/10.1214/009117904000000739 in the Annals of Probability (http://www.imstat.org/aop/) by the Institute of Mathematical Statistics (http://www.imstat.org)We consider random walks in a random environment of the type p_0+\gamma\

Abstract Based on the theory of natural selection it is not obvious why sexual reproduction should evolve in Mendelian populations. Sexually reproducing organisms incur a “cost of meiosis”: an asexual lineage would grow at twice the rate of a comparable sexual lineage.

On lifetimes in random environments
Naval Research Logistics, 1998Summary: For a component operating in random environment, whose hazard rate is assumed to be the realization of a suitable increasing stochastic process, conditions are found such that its lifetime is increasing in likelihood ratio. For the lifetimes of two components of the same kind some comparisons based on partial stochastic orders are presented ...

The problem of recurrence/transience for random motions in random media is studied. Apparently, \textit{F. Solomon} [Ann. Probab. 3, No. 1, 1-31 (1975; Zbl 0305.60029)] was the first to treat the problems of such kind: he studied one-dimensional random walk (r.w.) in random environment (r.e.). Some attention was given to r.w. in r.e.

On the non-recurrent random walk in a random environment
Discrete Mathematics and Applications, 2018 For weakly transient random walk in a random environment that tend at −∞ the limit theorem for the time of hitting a high level is proved.

Random walk in Markovian environment
Annals of Probability, 2008 We prove a quenched central limit theorem for random walks with bounded increments in a randomly evolving environment on $\Z^d$. We assume that the transition probabilities of the walk depend not too strongly on the environment and that the ...

Random Walks And Random Environments
1995Abstract This is the first volume of a two-volume work devoted to probability theory in physics, physical chemistry and engineering. This volume provides an introduction to the problem of "random walk" and its applications. In its simplest form, the random walk describes the motion of an idealized drunkard and is a discrete analogue of ...

Fluctuations of random walks in critical random environments
Physical Chemistry Chemical Physics, 2018Percolation networks have been widely used in the description of porous media but are now found to be relevant to understand the motion of particles in cellular membranes or the nucleus of biological cells. We here study the influence of the cluster size distribution on diffusion measurements in percolation networks.

Random Walks in Random Environment
2012Random walks in random environment constitute the best example to apply the theory developed in Chap. 2. In order to keep notation and results consistent with the previous chapter, we discuss only the time continuous case. By exploiting the translation invariance of the random environment, the position of the random walk is seen as an additive ...

Random walks in random environments
Physical Review A, 1984A renormalization-group analysis is carried out of the long-time behavior of random walks in an environment with a positionally random local drift force. It is argued that, independent of the strength of the disorder, the mean-square displacement, $〈{x}^{2}(t)〉$, is linear in time (i.e., diffusive) for dimensions $d\ensuremath{\gtrsim}2$.
