Random Walk on T-Fractal with Stochastic Resetting [PDF]
EntropyIn 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]
Sensors, 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 ...

Stochastic 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]
Magnetic 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

Random walks on hypergraphs [PDF]
Physical Review E, 2020 In the last twenty years network science has proven its strength in modelling many real-world interacting systems as generic agents, the nodes, connected by pairwise edges. Yet, in many relevant cases, interactions are not pairwise but involve larger sets of nodes, at a time.

Diffusivity of a random walk on random walks [PDF]
Random Structures & Algorithms, 2014 We consider a random walk $(Z^{(1)}_n, ..., Z^{(K+1)}_n) \in \mathbb{Z}^{K+1}$ with the constraint that each coordinate of the walk is at distance one from the following one. In this paper, we show that this random walk is slowed down by a variance factor $ _K^2 = \frac{2}{K+2}$ with respect to the case of the classical simple random walk without ...

Application of random walk to model temperature in 60 African cities for the 20th century [PDF]
E3S Web of Conferences, 2021 The 20th century is marked with climate change led by global warming. So far, many models have been applied to analyze the temperature change. However, a simple but interesting model, a random walk is hardly used in his regard.

Random walk on random walks: higher dimensions [PDF]
Electronic Journal of Probability, 2019 We study the evolution of a random walker on a conservative dynamic random environment composed of independent particles performing simple symmetric random walks, generalizing results of [16] to higher dimensions and more general transition kernels without the assumption of uniform ellipticity or nearest-neighbour jumps.
