Imagine trying to make an accurate three-dimensional model of a building using only pictures taken from different angles—but you're not sure where or how far away all the cameras were. Our big human ...

In this work, we present a 4 mm × 5 mm 2D ultrasound phased array transmitter with integrated piezoelectric ultrasound transducers on complementary metal-oxide-semiconductor (CMOS) integrated circuits ...

Classical source number estimators are usually derived under the assumption of uniform white noise, which may degrade substantially with unknown nonuniform sensor noise. Advanced estimators designed ...
