Ulam method for the Chirikov standard map
, 2010 We introduce a generalized Ulam method and apply it to symplectic dynamical maps with a divided phase space. Our extensive numerical studies based on the Arnoldi method show that the Ulam approximant of the Perron-Frobenius operator on a chaotic ...

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation
Molecular Ecology, Volume 35, Issue 9, May 2026.ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

The shallow shelf approximation as a "sliding law" in a thermomechanically coupled ice sheet model
, 2008 The shallow shelf approximation is a better ``sliding law'' for ice sheet modeling than those sliding laws in which basal velocity is a function of driving stress.

Recombination suppression in plant adaptation and speciation
New Phytologist, Volume 250, Issue 4, Page 2061-2077, May 2026.Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Public Administration Review, Volume 86, Issue 3, Page 769-791, May/June 2026.ABSTRACT Attracting talent to public administration is a highly relevant issue of practical concern and scholarly debate. Building on unique survey data of 424 individuals who switched jobs to join public administration, this study explores public employer attractiveness in a multi‐incentive setting, accounting for the experiences of a less explored ...

Deep Ritz Physics-Informed Neural Network Method for Solving the Variational Inequality
Variational inequalities are widely applied in mechanical engineering, fluid penetration, transportation, and other fields. In this paper, a Deep Ritz method based on Physics-Informed Neural Networks (PINNs) is proposed to enhance the accuracy and efficiency of solving elliptic variational inequalities.
