The study investigates the emergence of pedagogical reasoning among in-service Biology teachers as they observe a video-recorded feedback practice focused on biodiversity. Unlike cognitivist perspectives, we conceive pedagogical reasoning as a situated and relational process that...

Type I + II seesaw model in light of the new neutrino oscillation measurements
Abstract Global analysis of neutrino oscillation data slightly favors normal mass ordering. In this work, we investigate an extended scalar sector that naturally gives rise to a type I + II seesaw mechanism after spontaneous symmetry breaking and explore the interplay between col...

Electrochemical water splitting (EWS) and photocatalytic advanced oxidation processes (AOPs) are promising approaches for clean hydrogen production and environmental remediation; however, their efficiency is often limited by high overpotentials, rapid charge recombination, and po...

Bone fracture healing is a meticulously regulated process encompassing the inflammatory, reparative, and remodelling phases. Macrophages serve as pivotal coordinators within this cascade, with their polarisation from pro-inflammatory M1 to proregenerative M2 phenotypes, which pla...

Search for axions and dark photons using single molecule magnets
Molecular magnets, although analogous to familiar macroscopic magnets, offer a platform for next generation magnetic storage technologies with far higher data densities and prospective applications in quantum information science. When exposed to an external magnetic field, single...

The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Abstract We present deep Hubble Space Telescope (HST) imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an enigmatic and diverse population, with evolutionary pathways ranging...

Hydrogen-assisted combustion of GQD–DEE-enhanced WCO biodiesel in a dual-fuel CI engine
Abstract The relatively low performance and elevated nitrogen oxide (NOx) emissions associated with biodiesel-fueled compression ignition (CI) engines continue to limit their widespread application. To address these challenges, the present study investigates the combined influenc...

Clinical-histological and genetic features of rare variants of melanoma.
Melanoma is traditionally classified into a limited number of common clinicopathologic subtypes; however, routine clinical and histopathologic practice reveals a broad spectrum of rare variants and unusual morphologic patterns that pose significant diagnostic and therapeutic chal...
