Abstract: Simultaneous localization and mapping based on 3-D light detection and ranging (LiDAR) tends to degenerate in structural-less environments, leading to a distinct reduction in localization ...

Scientists haven’t had a precise way to arrange and study surface-bound extracellular vesicles and particles (EVPs) as they guide cell behavior. Researchers developed LEVA, which uses patterned ...

Microscopic extracellular vesicles bound to a surface in the shape of circles. Scientists made this pattern with LEVA (light-induced extracellular vesicle and particle adsorption). In stunning new ...

Learn how gradient descent really works by building it step by step in Python. No libraries, no shortcuts—just pure math and code made simple. Massie: Judges rejected 'lie' about Epstein files ICC ...

When Deluxe Paint came out with the original Amiga in 1985, it was the killer app for the platform. [Christopher Drum] starts his recent article on just that note, remembering the day he and his ...

Most of the animated videos you scroll past on Instagram are so expertly created with AI that they're peppered with comments asking, "Is this real?" But there's something enchanting about no-frills, ...

Passengers who weren't buckled aboard a Delta Air Lines flight to Europe were violently thrown into the ceiling and back down to the floor in July when the plane encountered severe turbulence in a ...

Abstract: This article presents a novel efficient method for gridless line spectrum estimation problems with single snapshot and sparse signals, namely the gradient descent least-squares (GDLS) method ...
