Directed random walk with random restarts: The Sisyphus random walk. [PDF]

open access: yesPhysical Review E, 2016
In this paper we consider a particular version of the random walk with restarts: random reset events which suddenly bring the system to the starting value.

Random walk on random walks [PDF]

open access: yesElectronic Journal of Probability, 2014
In this paper we study a random walk in a one-dimensional dynamic random environment consisting of a collection of independent particles performing simple symmetric random walks in a Poisson equilibrium with density 2 (0;1).

Bandit Algorithm Driven by a Classical Random Walk and a Quantum Walk [PDF]

open access: yesEntropy, 2023
Quantum walks (QWs) have a property that classical random walks (RWs) do not possess—the coexistence of linear spreading and localization—and this property is utilized to implement various kinds of applications.

A random-walk-based epidemiological model [PDF]

open access: yesScientific 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 centrality for temporal networks [PDF]

open access: yesNew Journal of Physics, 2014
Nodes can be ranked according to their relative importance within a network. Ranking algorithms based on random walks are particularly useful because they connect topological and diffusive properties of the network. Previous methods based on random walks,

Random Walk on T-Fractal with Stochastic Resetting [PDF]

open access: yesEntropy
In this study, we explore the impact of stochastic resetting on the dynamics of random walks on a T-fractal network. By employing the generating function technique, we establish a recursive relation between the generating function of the first passage ...

Testing for a Random Walk Structure in the Frequency Evolution of a Tone in Noise [PDF]

open access: yesSensors, 2022
Inference and hypothesis testing are typically constructed on the basis that a specific model holds for the data. To determine the veracity of conclusions drawn from such data analyses, one must be able to identify the presence of the assumed structure ...

Random walks on graphs [PDF]

open access: greenStochastic Processes and their Applications, 1974
AbstractIn this paper the following Markov chains are considered: the state space is the set of vertices of a connected graph, and for each vertex the transition is always to an adjacent vertex, such that each of the adjacent vertices has the same probability.

Transferring principles of solid-state and Laplace NMR to the field of in vivo brain MRI [PDF]

open access: yesMagnetic Resonance, 2020
Magnetic resonance imaging (MRI) is the primary method for noninvasive investigations of the human brain in health, disease, and development but yields data that are difficult to interpret whenever the millimeter-scale voxels contain multiple microscopic
