A Computational Framework for Myelin as a Regulator of Temporal Integration, Neuronal Excitability, and Synaptic Plasticity

Glia, Volume 74, Issue 12, December 2026.
Computational models illustrate how myelinating glia may shape the temporal integration of spikes upon a common postsynaptic target. Models show consequences for synaptic plasticity, neuronal excitability, and the fidelity of neural signals. ABSTRACT Myelin regulates neural signaling not only by enabling fast conduction but also by dynamically tuning ...

Study of Liquid Flow Through a Channel With Adjacent Porous Domains of Different Material Properties

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT A common subject in engineering disciplines is the study of flow in and around fractures or channels with adjacent porous domains. In this work, a unified approach based on the Theory of Porous Media (TPM) with an embedded Phase‐Field (PF) fracture model is used to investigate a flow scenario, where a channel separates two porous domains with ...

Effective Crack Resistance of a Simplified Ductile Heterogeneous Material With Circular Inclusions

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This contribution investigates the effective crack resistance obtained from a numerical crack‐growth experiment for a simplified two‐dimensional ductile heterogeneous material. The resolved microstructure contains circular inclusions. Their stiffness and fracture resistance are varied independently together with the ligament width between ...

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

International 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’

International 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

Fatigue &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

Plant, 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.
