Random Walk on the Range of Random Walk [PDF]
Journal of Statistical Physics, 2009 We study the random walk $X$ on the range of a simple random walk on $\mathbb{Z}^d$ in dimensions $d\geq 4$. When $d\geq 5$ we establish quenched and annealed scaling limits for the process $X$, which show that the intersections of the original simple random walk path are essentially unimportant.

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

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 ...

Normal Variance Mixture with Arcsine Law of an Interpolating Walk Between Persistent Random Walk and Quantum Walk [PDF]
EntropyWe propose a model that interpolates between quantum walks and persistent (correlated) random walks using one parameter on the one-dimensional lattice. We show that the limit distribution is described by the normal variance mixture with the arcsine law.

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

Matrix moments of the diffusion tensor distribution and matrix-variate Gamma approximation
Journal of Magnetic Resonance Open, 2021 Diffusion MRI allows for the non-invasive investigation of the microscopic architecture of biological tissues in vivo. While being sensitive to microstructural tissue changes, diffusion MRI yields poor specificity regarding the cause of these changes ...

Random walk on random walks: Low densities [PDF]
The Annals of Applied Probability, 2020 We consider a random walker in a dynamic random environment given by a system of independent simple symmetric random walks. We obtain ballisticity results under two types of perturbations: low particle density, and strong local drift on particles.

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 $σ_K^2 = \frac{2}{K+2}$ with respect to the case of the classical simple random walk without ...
