Advanced Intelligent Systems, EarlyView.Legged robots have advanced in environmental interaction through contact, but most works rely on fixed contact sequences. This work presents a new method based on an indirect optimization method for legged robots to automatically generate contact sequences for complex movements.

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,

Advanced Intelligent Systems, EarlyView.The Jump‐Enhancing Textile Suit integrates the Pneumatic Energy‐Storing Propulsion Actuator (PESPA) and the Triarticular Kinetic‐Chained Structure (TKiCS). PESPA stores elastic energy under pneumatic pressure and releases it during the propulsive phase to augment movement.

American Journal of Community Psychology, EarlyView.Abstract Youth participatory action research (YPAR) has been effectively used for substance use prevention. Yet, YPAR has not been evaluated for opioids, which negatively impact individuals and communities across the United States. The current study evaluated an opioid‐focused YPAR project.

American Journal of Community Psychology, EarlyView.Abstract Violent injuries tend to cluster together geospatially. The discriminatory housing practice of redlining undertaken by the United States federal government in the 1930s has been repeatedly linked with various contemporary community‐level disparities.
