Integration of Physics‐Based and Data‐Driven Approaches for Landslide Susceptibility Assessment
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 13, Page 3060-3097, September 2025.ABSTRACT Rainfall‐triggered landslides pose a significant threat to communities and infrastructure around the world. Various data‐driven and machine learning (ML) based algorithms have been applied to assess landslide susceptibility. However, purely data‐driven methods are affected by issues such as uncertainty in the selection of landslide ...

Single‐Asperity Friction and Wear in Seismic Faults: 2. DEM Simulations
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract Seismic faults are rough, and their geometrical complexity is an important research topic. In this work, we present a numerical model dedicated to the simulation of friction and wear in an idealized fault asperity, taking inspiration from an experimental device used in a companion paper.

International Journal of Mechanical System Dynamics, Volume 5, Issue 2, Page 345-353, June 2025.ABSTRACT In this article, the physics informed neural networks (PINNs) is employed for the numerical simulation of heat transfer involving a moving source under mixed boundary conditions. To reduce computational effort and increase accuracy, a new training method is proposed that uses a continuous time‐stepping through transfer learning.
