A Machine Learning Framework for Flood Risk Assessment With Imbalanced Data

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT This study presents a machine‐learning framework for identifying areas of elevated flood risk using imbalanced, high‐dimensional geospatial datasets. Using the Mandra River Basin in Greece as a case study, an extreme gradient boosting (XGBoost) classifier was trained on 11 flood‐related features including hydrological, meteorological, soil and

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

Mathematical Methods in the Applied Sciences, Volume 49, Issue 17, Page 17793-17815, 30 November 2026.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.

Dynamic Electrocatalysis Enhances the Oxygen Evolution Reaction Activity of Iridium Oxides

ChemElectroChem, Volume 13, Issue 22, 17 November 2026.
We demonstrate a significant enhancement (480%) of the oxygen evolution reaction (OER) by dynamic versus static operation. Time‐resolved operando spectroscopy combined with detailed modeling identifies the mechanism. Increased surface deprotonation, transiently responding to the square‐wave potential, accelerates the OER kinetics and decouples reaction

Curvature‐Induced Kinetic Trapping in Chemical Reactions

Journal of Computational Chemistry, Volume 47, Issue 30, November 15, 2026.
Reaction path curvature helps to detect obstacles to reaction progress in the absence of activation energy barriers. ABSTRACT Crossing an activation energy barrier in a chemical reaction needs time because enough kinetic energy needs to redistribute into the barrier‐crossing mode.
