Testing a Roy Model with Productivity Spillovers: Evidence from the Treatment of Heart Attacks [PDF]

open access: yes
Productivity spillovers are often cited as a reason for geographic specialization in production. A large literature in medicine documents specialization across areas in the use of surgical treatments, which is unrelated to patient outcomes.

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

open access: yesAdvanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

open access: yesAdvanced Science, EarlyView.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.
