On the stability of vacuum in the screened Vlasov–Poisson equation

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We study the asymptotic behavior of small data solutions to the screened Vlasov–Poisson equation on Rd×Rd$\mathbb {R}^d\times \mathbb {R}^d$ near vacuum. We show that for dimensions d⩾2$d\geqslant 2$, under mild assumptions on localization (in terms of spatial moments) and regularity (in terms of at most three Sobolev derivatives) solutions ...

Testing the Weak Cosmic Censorship Conjecture via Test Particle–Induced Overcharging/Overspinning of Kerr–Newman–Modified Gravity Black Hole

Advances in Astronomy, Volume 2026, Issue 1, 2026.
We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Deep Learning–Based Automated Crack Detection for Post‐Earthquake Damage Assessment in Reinforced Concrete Structures

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study explores the integration of deep learning technologies, specifically U‐Net based segmentation methods, for evaluating earthquake‐induced damages. The study leverages a dataset derived from the Kahramanmaraş earthquake to train and test deep learning models capable of identifying and quantifying structural damages such as concrete cracks. The

Rutin Improved the Meat Quality and Hepatointestinal Health of Nile Tilapia (Oreochromis niloticus) After High‐Level Fava Bean Feeding

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
A high‐level fava beans diet has been proven to enhance the texture characteristics of tilapia muscle, yet it can also induce hepatointestinal injury. Rutin, as a nutritional additive, has antioxidant and immune‐boosting effects. This study explored the regulatory effect of 150 and 300 mg/kg rutin on the muscle characteristics and hepatointestinal ...
