Random close packing or jamming of spheres in a container

Scientists at the theoretical institutes, Chinese Academy of Science and Cybermedia Center at Osaka University performed extensive computer simulations to generate and examine random packing of spheres. They show that the ...

Solving 'barren plateaus' is the key to quantum machine learning

Many machine learning algorithms on quantum computers suffer from the dreaded "barren plateau" of unsolvability, where they run into dead ends on optimization problems. This challenge had been relatively unstudied—until ...

Natural light flicker can help prevent detection

Movement breaks camouflage, making it risky for anything trying to hide. New research, published in the Proceedings of the Royal Society B today has shown that dynamic features common in many natural habitats, such as moving ...
