Electron and positron channeling and photon emission processes in boron doped periodically bent diamond
In this paper, theoretical and numerical analyses are conducted of the profiles of the planar (-110) crystallographic direction in the diamond layer doped with boron atoms. The planar profiles for periodic doping following several ideal dependencies of the boron concentration on the distance in the crystalline medium. Numerical simulations of the channeling and photon emission processes have been carried out for 855 MeV electron and 530 MeV positron beams incident on boron-doped diamond with a …

Eldercare robot helps people sit and stand, and catches them if they fall
MIT engineers built E-BAR, a mobile robot designed to physically support the elderly and prevent them from falling as they move around their homes. E-BAR acts as a set of robotic handlebars that follows a person from behind, allowing them to walk independently or lean on the robot’s arms for support.
