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.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Analysis of High-speed EMUs Noise Source
, 2015 To improve riding comfort and optimize noise insulation design for high-speed EMUs, the noise source was analyzed, and noise value of high-speed EMUs typical position passenger room was introduced. Noise source under different speed was discussed and indicated mainly from wheel-track noise and pneumatic noise. When the speed of vehicle was under 200 km/

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high
