“It’s not only about detecting falsehoods, it’s about proving reality,” Saliba said. The race was on to develop a tool that could accurately and reliably make the distinction. It was around this time ...

Objective Multi-cancer early detection (MCED) tests are novel technologies that detect cancer signals from a broad set of cancer types using a single blood sample. The objective of this study was to ...

Abstract: This paper presents a homodyne six-port network analyzer operating around 60 GHz. The power detection is realized by using Schottky zero-bias diodes. The conception of the system is driven ...
