Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Persistent Instability in Policy Debates: The Three‐Body Problem of Trade, Agriculture and the Environment

JCMS: Journal of Common Market Studies, Volume 64, Issue 5, Page 1715-1750, September 2026.
Abstract Literature on policy debates often analyses cases involving either a single or two policy fields, which typically result in stable equilibria, manifesting either as outright rejection of policy proposals, successful institutional change or the entrenchment of divisions into a deadlock.
