Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism
Advanced Robotics Research, EarlyView.Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and

Convective Mixing in Gas Giant Planets with Primordial Composition Gradients
The Astrophysical JournalLinking atmospheric measurements to the bulk planetary composition and ultimately the planetary origin is a key objective in planetary science. In this work, we identify the cases in which the atmospheric composition represents the bulk composition.

Advanced Robotics Research, EarlyView.A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.

Dynamics of Planetary Rings under Thermal Forces
The Astrophysical Journal LettersPlanetary rings provide natural laboratories for studying the fundamental processes that govern the evolution of planetary systems. However, several key features, such as the sharp inner edges of Saturn’s rings, remain unresolved.

XeraBorg: Neural Control of Tail‐Flick Escape for Backward Propulsion in Cyborg Crayfish
Advanced Robotics Research, EarlyView.This work presents the first controlled tail‐flick propulsion method for the cyborg Cherax quadricarinatus. Comprehensive experiments establish a foundational framework for using the crayfish's natural escape mechanism as a locomotion strategy, expanding its potential as an underwater and amphibious mobile robot.

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions
Advanced Robotics Research, EarlyView.Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.

Integrating Ecology and Economics in Agent‐Based Models to Support Agricultural Policy
Advanced Science, EarlyView.Agent‐based models are valuable tools for studying social‐ecological systems in agriculture. This review maps how existing agent‐based models represent the human and natural domains of agriculture, and discusses developments in economic and ecological agent‐based modeling.
