Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments

Journal of Field Robotics, EarlyView.
ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel

Extended Strahler Ordering to Distinguish Mapped River Channels From Overland Flow Pathways and Consistently Compare Digital Networks

River Research and Applications, EarlyView.
ABSTRACT Digital networks are virtual representations of freshwater systems that provide important inputs to, and mapping of, river classifications, simulation models, and quantitative data analyses for policy, planning, and management. Strahler order has often been used to characterize network configuration and as a proxy indicator of river channel ...

Between Emancipation and Domination? A Critical Analysis of Empowerment in a Women‐Only Development Program in Costa Rica's Coffee Sector

Sustainable Development, EarlyView.
ABSTRACT Female empowerment and its use in development contexts has histories in coloniality. Gender programs typically imply an individualistic, depoliticized concept. This article examines whether such initiatives can be supportive for empowerment. We apply an embedded qualitative case study of Bean Voyage's program to support female coffee producers

Design and Control of a Dual‐Coil Magnetic Guidewire for Smooth and Adaptive Curvature Steering in Vascular Intervention

SmartBot, EarlyView.
Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...
