Context‐free graphs and their transition groups

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

Hands‐on and Minds‐on? Findings on the Instructional Support of Preschool Teachers to Foster Children's Understanding of Scientific Practices

open access: yesScience Education, Volume 110, Issue 6, Page 1693-1708, November 2026.
ABSTRACT To participate effectively in modern society, it is essential to have both knowledge of scientific concepts and an understanding of scientific practices. Children develop initial knowledge and skills to engage in scientific practices, such as identifying patterns, long before entering school.

Beyond Bactericidal: Plasma Surface Engineering to Defeat Food Matrix‐Conditioning Layers

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The persistence of foodborne pathogens on industrial food contact surfaces continues to challenge global food safety despite advances in sanitation technologies. A central limitation of current antimicrobial strategies lies in their validation under simplified laboratory conditions that overlook the physicochemically driven formation of food ...

Fracture Modeling of Nearly Incompressible Hyperelastic Materials: A Phase‐Field Approach via Simo–Taylor–Pister Three‐Field Variation

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT Incompressibility is commonly observed in the majority of hyperelastic materials, which are fundamental to a wide range of technical applications owing to their distinctive properties, particularly their flexibility, stretchability, and resilience.
