Abstract: This article presents a method for effectively characterizing the dielectric permittivity of nematic liquid crystals (LCs) across a broad frequency range. These materials show significant ...

Abstract: Mainstream visual-inertial SLAM systems use point features for motion estimation and localization. However, point features do not perform well in scenes such as weak texture and motion blur.

December 23, 2025 - For years, AI "companions" lived in a regulatory gray zone. Highly personal, always available, and largely ungoverned, these systems — built to remember what you say, check in on ...
