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

IEEJ 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,

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.

Training Program for the Use of Magnification Loupes in Dentistry

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Although magnification loupes offer well‐documented advantages, their initial adaptation can be challenging, often deterring widespread adoption. Without sufficient training during this critical period, students may feel inadequately prepared, limiting their ability to benefit from loupes and contributing to reluctance in their ...

Biomechanical effects of equine training aids: A systematic review

Equine Veterinary Education, EarlyView.
Summary Equine training aids, including auxiliary reins such as draw reins, Pessoa‐type systems and side reins, are widely used during lungeing and ridden exercise to improve posture, back engagement and movement quality. Despite their extensive practical application, the biomechanical effects of these devices remain poorly defined and are often ...
