Random Walks in Random Environment [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2006
Random walks in random environments (RWRE's) have been a source of surprising phenomena and challenging problems since they began to be studied in the 70's. Hitting times and, more recently, certain regeneration structures, have played a major role in our understanding of RWRE's. We review these and provide some hints on current research directions and

Random walks with barriers [PDF]

open access: yesNature Physics, 2011
Restrictions to molecular motion by barriers (membranes) are ubiquitous in porous media, composite materials and biological tissues. A major challenge is to characterize the microstructure of a material or an organism nondestructively using a bulk transport measurement.

Delayed Random Walks and Control [PDF]

open access: yes, 2006
Issues of resonance that appear in non-standard random walk models are discussed. The first walk is called repulsive delayed random walk, which is described in the context of a stick balancing experiment. It will be shown that a type of "resonant" effect

Statistical modelling of rate gyros based on fully overlapping Allan variance

open access: yesIET Science, Measurement & Technology, 2022
Angular random walk and rate random walk are two dominant random noise components which are inherent in almost gyroscopes. Therefore, modelling these noise components accurately is very important. Here, a modified algorithm is proposed for estimating the

Random recursive trees and the elephant random walk. [PDF]

open access: yesPhysical Review E, 2015
One class of random walks with infinite memory, so-called elephant random walks, are simple models describing anomalous diffusion. We present a surprising connection between these models and bond percolation on random recursive trees.

On random random walks [PDF]

open access: yesThe Annals of Probability, 1996
We estimate the expected mixing time of a random walk on a finite group supported by a random polylogarithmic set of elements. Following the spectral approach of Broder and Shamir, we present an alternative proof of the Dou-Hildebrand estimate and show that it holds almost surely. Good bounds on diameters follow from these results.

A Novel Algorithm of Quantum Random Walk in Server Traffic Control and Task Scheduling

open access: yesJournal of Applied Mathematics, 2014
A quantum random walk optimization model and algorithm in network cluster server traffic control and task scheduling is proposed. In order to solve the problem of server load balancing, we research and discuss the distribution theory of energy field in ...

Random-walk in Beta-distributed random environment [PDF]

open access: yes, 2015
We introduce an exactly-solvable model of random walk in random environment that we call the Beta RWRE. This is a random walk in $$\mathbb {Z}$$Z which performs nearest neighbour jumps with transition probabilities drawn according to the Beta ...

Random walk with random resetting to the maximum position. [PDF]

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2015
We study analytically a simple random walk model on a one-dimensional lattice, where at each time step the walker resets to the maximum of the already visited positions (to the rightmost visited site) with a probability r, and with probability (1-r), it ...

IRWRLDA: improved random walk with restart for lncRNA-disease association prediction

open access: yesOncoTarget, 2016
In recent years, accumulating evidences have shown that the dysregulations of lncRNAs are associated with a wide range of human diseases. It is necessary and feasible to analyze known lncRNA-disease associations, predict potential lncRNA-disease ...
