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.

, 2019 A large number of symmetry-protected topological (SPT) phases have been hypothesized for strongly interacting spin-1/2 systems in one dimension. Realizing these SPT phases, however, often demands fine-tunings hard to reach experimentally. And the lack of

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 ...

Generalization Error in the Deep Ritz Method with Smooth Activation Functions
Communications in Computational PhysicsThe manuscript presents an in-depth theoretical analysis of the Deep Ritz method (DRM) and addresses the generalization error inherent in this deep learning paradigm for solving partial differential equations (PDEs), focusing specifically on the Poisson equation.

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 ...

Journal of Computational ScienceThis paper presents a novel approach that combines the Deep Ritz Method (DRM) with Fourier feature mapping to solve minimization problems comprised of multi-well, non-convex energy potentials. These problems present computational challenges as they lack a global minimum. Through an investigation of three benchmark problems in both 1D and 2D, we observe

‘Fixed-axis’ magnetic orientation by an amphibian: non-shoreward-directed compass orientation, misdirected homing or positioning a magnetite-based map detector in a consistent alignment relative to the magnetic field? [PDF]
, 2002 Experiments were carried out to investigate the earlier prediction that prolonged exposure to long-wavelength (>500 nm) light would eliminate homing orientation by male Eastern red-spotted newts Notophthalmus viridescens.

Inexact Uzawa-Double Deep Ritz Method for Weak Adversarial Neural Networks
The emergence of deep learning has stimulated a new class of PDE solvers in which the unknown solution is represented by a neural network. Within this framework, residual minimization in dual norms -- central to weak adversarial neural network approaches -- naturally leads to saddle-point problems whose stability depends on the underlying iterative ...
