A Branching Random Walk with a Barrier
The Annals of Applied Probability, 1991 A supercritical branching random walk with independent displacements having negative mean is equipped with a left-hand barrier which annihilates individuals which would otherwise pass through it. A simple criterion is obtained for the population to die out with probability one.

A N-branching random walk with random selection
Latin American Journal of Probability and Mathematical Statistics, 2017 We consider an exactly solvable model of branching random walk with random selection, which describes the evolution of a population with $N$ individuals on the real line. At each time step, every individual reproduces independently, and its offspring are positioned around its current locations.

Survival of Branching Random Walks in Random Environment [PDF]
Journal of Theoretical Probability, 2009 We study survival of nearest-neighbour branching random walks in random environment (BRWRE) on ${\mathbb Z}$. A priori there are three different regimes of survival: global survival, local survival, and strong local survival. We show that local and strong local survival regimes coincide for BRWRE and that they can be characterized with the spectral ...

On statistical models on super trees
Journal of High Energy Physics, 2018 We consider a particular example of interplay between statistical models related to CFT on one hand, and to the spectral properties of ODE, known as ODE/IS correspondence, on the other hand. We focus at the representation of wave functions of Schrödinger

Moments of exit times from wedges for non-homogeneous random walks with asymptotically zero drifts [PDF]
, 2013 We study quantitative asymptotics of planar random walks that are spatially non-homogeneous but whose mean drifts have some regularity. Specifically, we study the first exit time $\tau_\alpha$ from a wedge with apex at the origin and interior half-angle $

Random walk on barely supercritical branching random walk [PDF]
Probability Theory and Related Fields, 2019 Let $\mathcal{T}$ be a supercritical Galton-Watson tree with a bounded offspring distribution that has mean $μ>1$, conditioned to survive. Let $φ_{\mathcal{T}}$ be a random embedding of $\mathcal{T}$ into $\mathbb{Z}^d$ according to a simple random walk step distribution.

Stochastic Dynamics of Proteins and the Action of Biological Molecular Machines
Entropy, 2014 It is now well established that most if not all enzymatic proteins display a slow stochastic dynamics of transitions between a variety of conformational substates composing their native state.

Molecular Oncology, EarlyView.Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Multifractal Analysis of Refined Sets in Branching Random Walks on Galton–Watson Trees
Fractal and FractionalIn this paper, we investigate refined level sets associated with branching random walks on the boundary of a supercritical Galton–Watson tree. More precisely, for a prescribed deterministic sequence s:=(rn,r˜n), we introduce refined deviation sets ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
