Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Journal of Manufacturing and Materials ProcessingDie-sink electric discharge machining (EDM) is essential for shaping complex geometries in hard-to-machine materials. This study aimed to optimize key input parameters, such as the discharge current, gap voltage, pulse-on time, and pulse-off time, to ...

British Educational Research Journal, EarlyView.Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Assessment of Recast Layer while Machining Die Steel D3 on EDM
International Journal of Experimental Research and ReviewThe material melted and quickly solidified on the surface, forming a Recast layer over the machined surface. The present experimental assessment measures the extent of influence of machine variables towards the deposition of recast material post-machining Die Steel D3.

Phenomenology of a Long-Lived LSP with R-Parity Violation
, 2015 We present the leading experimental constraints on supersymmetric models with R-parity violation (RPV) and a long-lived lightest superpartner (LSP). We consider both the well-motivated dynamical RPV scenario as well as the conventional holomorphic RPV ...
