Planning and Control Framework for a Quadruped Robot With Changeable Configuration

Advanced Intelligent Systems, EarlyView.
Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,

Cryogenic Carbon Monoxide Oxidation on Cuprous Oxide

Angewandte Chemie, EarlyView.
A reconstructed Cu2O surface with pyramidal units (PY) contains both adsorption and reaction sites for CO oxidation. A suite of spectroscopy techniques and calculations were used to characterize the fundamental surface chemistry occurring below 100 K, where typically a metal/oxide interface is required.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.
