Symplectic Realization of Generalized Snyder–Poisson Algebra
UniverseWe investigate Snyder spacetime and its generalizations, including Yang and Snyder–de Sitter spaces, which constitute manifestly Lorentz-invariant noncommutative geometries.

Journal of the Experimental Analysis of Behavior, Volume 125, Issue 1, January 2026.Abstract A common method for studying derived relations is the matching‐to‐sample (MTS) preparation. However, certain aspects of its training format potentially hinder the emergence of new relations. The training version of the implicit relational assessment procedure (training‐IRAP) may present an alternative.

The Normal Casimir Force for Lateral Moving Planes with Isotropic Conductivities
PhysicsWe consider the two planes at zero temperature with isotropic conductivity that are in relative lateral motion with velocity v and interplane distance a. Two models of conductivity are taken into account—the constant and frequency-dependent Drude models.

Bridging the Gap in Brazilian Literacy: Kalulu Phonics Provides Gains in 1st Grade Reading
Reading Research Quarterly, Volume 60, Issue 4, October/December 2025.In Brazil, constructivist methods—which promote whole‐word reading and reject phonics—were introduced during a time of positive educational expansion, aiming to bring schooling to all children. While this moment marked important social progress, the methods themselves lacked scientific support. Over time, phonics has been shown to be more effective for

Symplectic groupoids and Poisson electrodynamics
Journal of High Energy PhysicsWe develop a geometric approach to Poisson electrodynamics, that is, the semi-classical limit of noncommutative U(1) gauge theory. Our framework is based on an integrating symplectic groupoid for the underlying Poisson brackets, which we interpret as the

Alteration of cleaner wrasse cognition and brain morphology under marine heatwaves
Functional Ecology, Volume 39, Issue 8, Page 1894-1905, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Heatwaves, exacerbated by global warming, are progressively affecting various ecosystems, with coral reefs among the most susceptible. Within these ecosystems, cleaner wrasses (Labroides dimidiatus) engage in cooperative interactions with client fish by removing ...
