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

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
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,

Proctoring in a Second Language: Exploring Fairness and Justice in Remote English Language Testing

open access: yesTESOL Quarterly, EarlyView.
Abstract Remote proctoring is increasingly common in English language testing (Isbell & Kremmel, 2020), yet it often requires communication in the target language, unlike in‐person centers that may offer support in test‐takers' first language. Although prior studies have noted communication challenges in remote testing environments (Green & Lung, 2021;

Oxidative Stress Biomarkers in the Shrimp Macrobrachium amazonicum (Heller, 1862): Assessment in an Environmental Preservation Area in the Brazilian Amazon

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities generate a significant amount of pollutants that are released into the environment, causing physiological and ecological disturbances. Among the xenobiotics present in aquatic ecosystems, numerous chemical and organic compounds have oxidative potential or are metabolized through oxidative processes, which may amplify ...
