Robustness of Aharonov-Bohm cages in quantum walks [PDF]
Physical review B, 2022 It was recently shown that Aharonov-Bohm (AB) cages exist for quantum walks (QW) on certain tilings – such as the diamond chain or the dice (or T3) lattice – for a proper choice of coins.

2-Hopper: Accurately Estimate Individual and Social Attributes of Social Networks With Fewer Repeats via Random Walk [PDF]
IEEE Access, 2019 Random-walk based sampling is widely used to characterize large graphs by producing samples in the form of nodes. However, existing random-walk based sampling methods only focus on the estimation accuracy of structural properties but suffer from repetitive samples which have adverse effects on obtaining accurate information about the structures over ...

Bayesian inference of transition matrices from incomplete graph data with a topological prior
EPJ Data Science, 2023 Many network analysis and graph learning techniques are based on discrete- or continuous-time models of random walks. To apply these methods, it is necessary to infer transition matrices that formalize the underlying stochastic process in an observed ...

Invariance principle for biased bootstrap random walks [PDF]
Stochastic Processes and their Applications, 2017 Our main goal is to study a class of processes whose increments are generated via a cellular automata rule. Given the increments of a simple biased random walk, a new sequence of (dependent) Bernoulli random variables is produced.

A Random Walk Approach for Avoiding Unwanted Users in Competitive Social Network
IEEE Access, 2020 How to detect influential customers to broadcast advertisements to the maximum range is a key issue in effective viral marketing. If multiple companies sell the same product in viral marketing campaigns, there was competition between them.

International Journal of Behavioral Nutrition and Physical Activity, 2022 Background Older adults are the least active population in the U.S. Low-income communities have fewer physical activity (PA) resources, contributing to less PA and increased chronic disease risk. This study assessed the effect of the multilevel, peer-led,

Repeated Quantum Interactions and Unitary Random Walks [PDF]
, 2007 Among the discrete evolution equations describing a quantum system ℋS undergoing repeated quantum interactions with a chain of exterior systems, we study and characterize those which are directed by classical random variables in ℝN.

On a class of unbalanced step-reinforced random walks [PDF]
Stochastic Processes and their ApplicationsA step-reinforced random walk is a discrete-time stochastic process with long-range dependence. At each step, with a fixed probability $\alpha$, the so-called positively step-reinforced random walk repeats one of its previous steps, chosen randomly and ...

Leader election using random walks [PDF]
, 2016 In the classical leader election procedure all players toss coins independently and those who get tails leave the game, while those who get heads move to the next round where the procedure is repeated.
