The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Applied Research, Volume 5, Issue 4, August 2026.An XGBoost‐SHAP framework accurately predicted skid resistance evolution in steel slag ultra‐thin wearing courses under accelerated loading. Surface texture amplitude (Rz, Rq) and loading cycles dominated BPN variation, while 50% steel slag replacement provided a cost‐effective balance between anti‐skid durability and material use.

Control System for the Navigation of the Agricultural Robots: A Review
Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Regeneration response to post‐disturbance forest management in Central Europe
Journal of Applied Ecology, Volume 63, Issue 8, August 2026.As disturbance activity intensifies, forest management must identify strategies to facilitate the rapid recovery of disturbed sites. By studying 868 disturbed sites across Central Europe, we found that active post‐disturbance management significantly enhanced tree regeneration in regional disturbance hotspots.

Physiological Reports, Volume 14, Issue 15, August 2026.Abstract Repeated‐sprint ability is a key determinant of soccer performance. However, some mechanical and physiological responses underlying this task remain incompletely understood. This study characterized mechanical responses (force, velocity, and power) and regional muscle oxygen saturation (rSmO2) in the vastus lateralis (VL) and biceps brachii ...
