In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is evidence of a rare ...

Abstract: Despite progress in applying Vision Transformers to rotated object detection in remote sensing images, current cascade activation mask mechanisms still exhibit two critical limitations: ...

A minimal, educational 3D rendering engine built with Python and Matplotlib. This project demonstrates the core concepts of perspective projection to help understand how 3D objects are rendered on a ...
