Bespoke manipulation of light by Steven Johnson's group could find uses in cellphone lenses, smart-car sensors, optical fibers. A metasurface features millions of individual, microscopic features.
MIT researchers have developed a model that can predict traffic jams. The have come up with a formula of 'phantom' jams, based on the equations that describe detonation waves caused by explosions.
VGGT-SLAM revolutionizes robotic mapping, utilizing SL(4) manifold optimization to tackle reconstruction ambiguity and enhance environmental perception.
