Abstract: This article investigates the target elevation estimation problem for passive radar based on a double-layer uniform circular array (DUCA). First, we propose a calibration method for the DUCA ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...

Imaging-based single-cell physiological profiling holds great potential for uncovering fundamental bacterial cold shock response (CSR) mechanisms, but its application is impeded by severe focus drift ...
