A widely used breathing test for patients with respiratory problems is flawed, according to a new study, as it fails to account for individual breathing patterns. Increasing the measurement time to two minutes and using specialized equipment could improve accuracy.
A survey of 340 UK residents found that positive social interactions with Chinese people reduced support for discriminatory policies. People with negative experiences were more likely to be fearful and supportive of anti-Chinese measures.
Scientists at Hokkaido University developed a saliva test that detects asymptomatic COVID-19 cases with high sensitivity and specificity. The study found that saliva samples can accurately identify infected individuals without symptoms, reducing the risk of viral transmission to healthcare workers.
KAUST researchers developed a statistical model providing the best wind forecast yet for Saudi Arabia, aiming to increase renewable energy in the grid and reach 9 gigawatts of installed wind energy by 2030. The model uses advanced statistical approaches to jointly model wind speed and direction, showing improved prediction performance.
Researchers developed a novel γ-radiation intensity sensor using polymethylmethacrylate and polyvinyl chloride membranes. The sensor changes color in response to increasing radiation intensity, allowing for quick and easy measurement.
A new simulation approach has enabled faster computation of complex airfoil noise characteristics under extreme conditions, accelerating the development of quieter designs. The method uses a wall-modeled large-eddy simulation to model near-surface flows at high resolution while reducing computational intensity.
