Digital Methods for the Fatigue Assessment of Engineering Steels

open access: yesAdvanced Engineering Materials, Volume 27, Issue 8, April 2025.
The use of engineering steels is often limited by their fatigue strength. In the sake of a faster product development, the fatigue behavior can be predicted by machine learning (ML). In this work, ML is applied on a heterogeneous database, covering a wide range of steel types.

The Hitting Times with Taboo for a Random Walk on an Integer Lattice

open access: yes, 2011
For a symmetric, homogeneous and irreducible random walk on d-dimensional integer lattice Z^d, having zero mean and a finite variance of jumps, we study the passage times (with possible infinite values) determined by the starting point x, the hitting ...

DTFLOW: Inference and Visualization of Single-cell Pseudotime Trajectory Using Diffusion Propagation

open access: yesGenomics, Proteomics & Bioinformatics, 2021
One of the major challenges in single-cell data analysis is the determination of cellular developmental trajectories using single-cell data. Although substantial studies have been conducted in recent years, more effective methods are still strongly ...

The range of tree-indexed random walk in low dimensions

open access: yes, 2015
We study the range $R_n$ of a random walk on the $d$-dimensional lattice $\mathbb{Z}^d$ indexed by a random tree with $n$ vertices. Under the assumption that the random walk is centered and has finite fourth moments, we prove in dimension $d\leq3$ that ...

Martin boundaries and asymptotic behavior of branching random walks [PDF]

open access: yesarXiv, 2023
Let $G$ be an infinite, locally finite graph. We investigate the relation between supercritical, transient branching random walk and the Martin boundary of its underlying random walk. We show results regarding the typical asymptotic directions taken by the particles, and as a consequence we find a new connection between $t$-Martin boundaries and ...

Strong local survival of branching random walks is not monotone

open access: yes, 2013
The aim of this paper is the study of the strong local survival property for discrete-time and continuous-time branching random walks. We study this property by means of an infinite dimensional generating function G and a maximum principle which, we ...

Branching Processes in Simple Random Walk [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
Let N ( a ) N(a) be the number of overcrossings of height a a in a simple random walk. For p > 1 / 2 p > 1/2 , the process N ( 0 ) , N ( 1 ) ,

Rational Engineering of Nanostructured AgM (M = Au, Pt, Pd) Bimetallic Electrodes via Galvanic Replacement for Glycerol Electrolysis

open access: yesAdvanced Engineering Materials, Volume 27, Issue 9, May 2025.
This study demonstrates the feasibility of fabricating free‐standing carbon paper electrodes by electroplating and galvanic replacement. Nanostructured AgM (M = Au, Pt, Pd) bimetallic catalysts are directly grown on the electrode substrate, which exhibit good performance for glycerol electrolysis, a sustainable approach for the co‐production of green ...
