Random Walks in Random Environment [PDF]
Journal 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]
Nature 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.

A Novel Algorithm of Quantum Random Walk in Server Traffic Control and Task Scheduling
Journal 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]
, 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]
Physical 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
OncoTarget, 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 ...

Discriminative Deep Random Walk for Network Classification
Annual Meeting of the Association for Computational Linguistics, 2016 Deep Random Walk (DeepWalk) can learn a latent space representation for describing the topological structure of a network. However, for relational network classification, DeepWalk can be suboptimal as it lacks a mechanism to optimize the objective of the

Random walk on sparse random digraphs [PDF]
Probability theory and related fields, 2015 A finite ergodic Markov chain exhibits cutoff if its distance to equilibrium remains close to its initial value over a certain number of iterations and then abruptly drops to near 0 on a much shorter time scale.

Identifying diseases-related metabolites using random walk
BMC Bioinformatics, 2018 Background Metabolites disrupted by abnormal state of human body are deemed as the effect of diseases. In comparison with the cause of diseases like genes, these markers are easier to be captured for the prevention and diagnosis of metabolic diseases ...
