Abstract: Capturing object semantics and their spatial relationships is crucial to estimating scene similarity for loop closure detection. Existing semantic loop closure detection methods generally ...

Abstract: Optical modulators consisting of parallel Mach-Zehnder interferometers can generate complicated signals with precise bias control. A characterization method of such devices using optical ...

Tiny metalenses split a laser into 120,000+ points, letting 3D nanoprinting cover wafer-size areas with 113 nm detail at 1,000 speed.

Ever noticed how stealth jets like the F-35, F-22, B-2, and Su-57 are covered in sharp, parallel edges and strange angled panels instead of smooth curves? That geometry is not for looks, it is there ...
