Coexistence, crossover and extirpation in coalescent communities and ecotones

Oikos, Volume 2026, Issue 7, July 2026.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Approximate Ricci‐Flat Metrics for Calabi–Yau Manifolds

Fortschritte der Physik, Volume 74, Issue 7, July 2026.
ABSTRACT We outline a method to determine analytic Kähler potentials with associated approximately Ricci‐flat Kähler metrics on Calabi–Yau manifolds. Key ingredients are numerically calculating Ricci‐flat Kähler potentials via machine learning techniques and fitting the numerical results to Donaldson's ansatz.

Physics‐Informed Neural Networks for Battery Degradation Prediction Under Random Walk Operations

Quality and Reliability Engineering International, Volume 42, Issue 5, Page 1923-1940, July 2026.
ABSTRACT This study addresses the challenge of predicting the state of health (SoH) and capacity degradation in Battery Energy Storage Systems (BESS) under highly variable conditions induced by frequent control adjustments. In environments where random walk behavior prevails due to stochastic control commands, conventional estimation methods often ...

Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, Volume 42, Issue 6, Page 1172-1187, July 2026.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.
