Abstract: One of the main tasks of a wideband reconnaissance receiver is to measure the carrier frequency and direction-of-arrival (DOA) rapidly once the radar signal is intercepted. To address the ...

Abstract: Low sampling frequency challenges the exact identification of continuous-time (CT) dynamical systems from sampled data, even when their models are identifiable. A necessary and sufficient ...

Preliminary analysis rules out a lab leak as the cause of an African swine fever outbreak that has rocked Spain's lucrative pork industry, but further tests are needed, authorities said Tuesday.

Abstract: Given that the sampling and arrangement of the array need a reasonable standard to guide in high-precision magnetocardiography (MCG) imaging, the sampling range required for robust ...
