Uncertainties of Failure in Bending Experiments

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT During the manufacture of mechanical structures, their calculation and experimental investigation, deviations from the deterministic state arise, which are based on uncertainties in the mechanical parameters. The propagation of such uncertainties is evaluated in two experimental setups here.

Quasinormal Modes for Coherent Quantum Black Holes

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT Coherent quantum black holes are quantum geometries obtained by means of a mean‐field‐like approach to the gravitational interaction. This procedure attenuates the classical spacetime singularities of general relativity by replacing them with integrable singularities in the quantum‐corrected geometry. After discussing some relevant observables

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice

Small Methods, Volume 10, Issue 5, 9 March 2026.
Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

A Random Walker Algorithm for Plate Boundary Detection in Spherical Mantle Convection Models and Global Geophysical Data Sets: Application to Euler Vector Determination

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract As spherical shell mantle convection models become increasingly commonplace, understanding how plates are generated has raised the issue of how to recognize whether rigid plates are present in model output. Tectonocists have long recognized that intraplate regions are not rigid without exception.

Dynamic Earthquake Source Inversion With Generative Adversarial Network Priors

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Dynamic earthquake source inversion consists of inferring frictional parameters and initial stress on a fault consistent with recorded seismological and geodetic data and with dynamic earthquake rupture models. In a Bayesian inversion approach, the nonlinear relationship between model parameters and data requires a computationally demanding ...

Investigating the Effect of Internal Waves on Vertical Ice Melting Rates

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Polar ice sheets are losing mass as a result of ocean‐driven melting processes and thus affecting global climate and sea level. Understanding the relevant dynamics and interactions at the ice‐ocean interface is crucial to developing more accurate sea‐level rise projections, but key ocean processes have not yet been considered in detail.
