A random-walk-based epidemiological model

Scientific Reports, 2021
Random walkers on a two-dimensional square lattice are used to explore the spatio-temporal growth of an epidemic. We have found that a simple random-walk system generates non-trivial dynamics compared with traditional well-mixed models.

Random walk versus random line [PDF]

, 2009
We consider random walks X_n in Z+, obeying a detailed balance condition, with a weak drift towards the origin when X_n tends to infinity. We reconsider the equivalence in law between a random walk bridge and a 1+1 dimensional Solid-On-Solid bridge with ...

A Review of Random Walk-Based Method for the Identification of Disease Genes and Disease Modules

IEEE Access, 2023
Traditional techniques for identifying disease genes and disease modules involve high-cost clinical experiments and unpredictable time consumption for analysis.

Impatient Random Walk [PDF]

Journal of Theoretical Probability, 2019
We introduce a new type of random walk where the definition of edge reinforcement is very different from the one in the reinforced random walk models studied so far, and investigate its basic properties, such as null/positive recurrence, transience, and speed. Two basic cases will be dubbed "impatient" and"ageing" random walks.

Slowdown estimates for one-dimensional random walks in random environment with holding times [PDF]

, 2018
We consider a one dimensional random walk in random environment that is uniformly biased to one direction. In addition to the transition probability, the jump rate of the random walk is assumed to be spatially inhomogeneous and random.

Re-examining analyst superiority in forecasting results of publicly-traded brazilian companies / Reexaminando a superioridade dos analistas ao preverem resultados de empresas brasileiras de capital aberto

RAM. Revista de Administração Mackenzie, 2021
Purpose: This research examines the superiority of analysts over random walk models in forecasting the results of publicly-traded Brazilian companies in the short and long term. Originality/value: The literature indicates the uncontested superiority

Non-backtracking random walk [PDF]

, 2012
We consider non-backtracking random walk (NBW) in the nearest-neighbor setting on the Zd-lattice and on tori. We evaluate the eigensystem of the m X m-dimensional transition matrix of NBW where m denote the degree of the graph.

Bootstrap random walks

Stochastic Processes and their Applications, 2016
Consider a one dimensional simple random walk $X=(X_n)_{n\geq0}$. We form a new simple symmetric random walk $Y=(Y_n)_{n\geq0}$ by taking sums of products of the increments of $X$ and study the two-dimensional walk $(X,Y)=((X_n,Y_n))_{n\geq0}$. We show that it is recurrent and when suitably normalised converges to a two-dimensional Brownian motion with
