Evolution and Conceptual Insights into the Geometric Phase of Light: A Comprehensive Review

open access: yesAdvanced Photonics Research, Volume 7, Issue 6, June 2026.
This review presents a unified account of the geometric phase of light, linking its fundamental principles to diverse manifestations in polarization, spatial, and vector modes. By connecting theoretical frameworks with key experimental realizations, it reveals a coherent physical picture that deepens understanding and stimulates new directions in ...

On finite elation generalized quadrangles with symmetries

open access: yes, 1996
We study the structure of finite groups G which act as elation groups on finite generalized quadrangles and contain a full group of symmetries about some line through the base point.

Thermal Conductivity Across the Nonpolar‐Polar Phase Transition in Incipient Ferroelectric KTaO3

open access: yesAdvanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Phonon dispersion of the cubic nonpolar ground‐state and a ferroelectric tetragonal phase, stabilized by a compressive strain of 2%. ABSTRACT The manipulation of the lattice of polar materials via external electric fields is an effective way to dynamically control the heat flux, accessing different thermal conductivity, κ${\bm \kappa }$, states ...

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

open access: yesAIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

Enhancing Pre‐Service Teachers' Understanding of Quadrilaterals Through Wiki‐Supported Collaborative Learning

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 3, June 2026.
ABSTRACT Background Pre‐service mathematics teachers frequently struggle with understanding the definitions and hierarchical classifications of quadrilaterals, often misidentifying inclusive relationships. These misconceptions hinder their ability to teach geometry effectively and reflect gaps in both content knowledge and pedagogical readiness.
