Correction of the radon exhalation rate using the Kalman filtering to reduce measurement errors

Nuclear Engineering and Technology
The RAD7 detector is widely used for measuring the radon exhalation rate from the surfaces of media such as soil, rocks, and building materials. However, during the measurement process, the accuracy of the results is prone to interference due to the ...

Effects of flow‐controlled expiration on oxygenation and early recovery in horses undergoing general anaesthesia

Equine Veterinary Journal, EarlyView.
Abstract Background FLow‐controlled EXpiration (FLEX) has been shown to significantly enhance oxygenation in horses under clinical and experimental conditions. Objectives To compare pulmonary gas exchange during early recovery following general anaesthesia in horses ventilated with FLEX compared with conventional intermittent positive pressure ...

From hydrogels to eutectogels: Emerging platforms for stretchable electronics

FlexMat, EarlyView.
The transition of wearable electronics toward long‐term reliability requires materials that resist dehydration without sacrificing tissue‐like softness and ionic conductivity. Eutectogels fulfill these demands by immobilizing deep eutectic solvents within tailored polymer networks.
