CONTRIBUTIONS OF MULTI-SENSORY STIMULATION (SNOEZELEN) IN OLDER PEOPLE WITH DEMENTIA


Postsaturation dynamics and superluminal propagation of a superradiant spike in a free-electron laser amplifier

We study the dynamics of an isolated spike of radiation in superradiant regime.We show that conditions exist where the pulse moves with a group velocity larger than the velocity of light in vacuum and is Oregano followed by a pedestal resulting from a complex postsaturation dynamics.The tail is constituted by a train of subpulses with both transver
