Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

Journal of Anatomy, Volume 248, Issue 5, Page 843-872, May 2026.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

On the finite generation of ideals in tensor triangular geometry

Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract Inspired by Cohen's characterization of Noetherian commutative rings, we study the finite generation of ideals in tensor triangular geometry. In particular, for an essentially small tensor triangulated category K$\mathcal {K}$ with weakly Noetherian spectrum, we show that every prime ideal in K$\mathcal {K}$ can be generated by finitely many ...

The fundamental group of the complement of a generic fiber‐type curve

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract In this paper, we describe and characterize the fundamental group of the complement of generic fiber‐type curves, that is, unions of (the closure of) finitely many generic fibers of a component‐free pencil F=[f:g]:CP2⤍CP1$F=[f:g]:\mathbb {C}\mathbb {P}^2\dashrightarrow \mathbb {C}\mathbb {P}^1$.

Phase‐Field Fracture Simulation of Pressurized Concrete Microstructure

International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT Pressurized cracks in concrete have a significant impact on the safety and durability of concrete structures. The peak strength of concrete is reduced in the presence of pressurized cracks. However, conducting pressure‐coupled strength evaluation experiments requires extensive effort, and simulation tools can complement the time‐consuming and ...

Multiple Time‐Scale Homogenization of Coupled Corrosion‐Fatigue in Structural Concrete

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT Reinforced concrete structures exposed to chloride‐rich environments and cyclic mechanical loading experience simultaneous corrosion of steel reinforcement and fatigue‐induced concrete cracking, leading to complex, nonlinear degradation that cannot be accurately captured by conventional sequential analyses.

Electromagnetic Wave Localization in One‐Dimensional Hyperuniform Disordered Structures

Advanced Optical Materials, Volume 14, Issue 16, 24 April 2026.
Stealthy hyperuniform disorder in one dimension exhibits strikingly different structural and photonic behavior compared with higher dimensions. By analysing spatial correlations and electromagnetic eigenstates, we show that short‐range pairing strongly shapes localization and transport regimes.

Low‐Ru‐Content CuCoRu Aerogel for Boosted Electrocatalytic Nitrate Reduction to Ammonia

EcoEnergy, Volume 4, Issue 2, April 2026.
Low‐Ru‐content Cu5Co5Ru aerogel with enhanced hydrogenation ability and 3D robust aerogel skeletons enables high‐efficiency and long‐term electrocatalytic nitrate reduction to ammonia at low overpotential, achieving an exceptional ammonia yield rate of 2.7 ± 0.1 mmol cm−2 h−1 and a high Faradaic efficiency of ∼97% at −0.1 V versus RHE as well as an ...
