In a new study, researchers demonstrate long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. The paper is ...

Scientists at the University of Oxford have unveiled a pioneering method for capturing the full structure of ultra-intense ...

A theoretical analysis of Doppler frequency estimators proposed to be used in ultrasonic moving target indicator (MTI) measurements of velocity profiles in blood flow is given. The estimators give an ...
