In Vivo Dynamic D2O‐MRI for Quantifying Apparent CSF Water Renewal Across Ventricular and Extraventricular Compartments

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The choroid plexus has long been regarded as the principal source of cerebrospinal fluid (CSF), yet this view remains unresolved. We developed a dynamic indirect D2O MRI approach to quantify regional apparent CSF water renewal in vivo in rats at 9.4 T.

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.
