Rational points on even‐dimensional Fermat cubics

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Control Design Based on Generalized Lur'e Lyapunov Functions for Sampled‐Data Lur'e Systems

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 16, Page 7450-7463, 10 November 2026.
ABSTRACT This article addresses the synthesis of stabilizing control laws for aperiodic sampled‐data Lur'e systems. Based on a hybrid system representation of the closed‐loop system and a timer‐dependent generalized Lur'e–Postnikov type Lyapunov function, stabilization conditions are obtained by separating decision variables with the application of two

A Data‐Driven Approach to the Issue of ‘Catching Up With Monolinguals’

open access: yesInternational Journal of Language &Communication Disorders, Volume 61, Issue 6, November/December 2026.
ABSTRACT Background Multilingual children in monolingual education systems are generally assessed against monolingual norms, raising questions about identifying genuine language support needs versus expected developmental trajectories. Aims This study aimed to identify: (1) the amount of cumulative exposure to the societal language (SL) beyond which ...

Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4572-4585, November 2026.
ABSTRACT This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture material properties.

CO2 Fertilisation of Growth in Wild C4 Grasses may be Amplified by Upregulated Photosynthesis

open access: yesPlant, Cell &Environment, Volume 49, Issue 11, Page 8870-8882, November 2026.
ABSTRACT Rising atmospheric CO2 is expected to have limited direct effects on C4 photosynthesis because the carbon‐concentrating mechanism maintains near‐saturating CO2 at Rubisco. Consequently, growth responses of C4 plants to elevated CO2 (eCO2) are generally attributed to indirect improvements in plant water relations.

Homogenization of two fluid flow in porous media

open access: yes, 2015
The macroscopic behavior of air and water in porous media is often approximated using Richards’ equation for the fluid saturation and pressure. This equation is parametrized by the hydraulic conductivity and water release curve.

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds
