Quantum backreaction on chronology horizons

Abstract We extend in two directions our recent investigation of strongly interacting quantum fields in a class of spacetimes with chronology horizons (Misner spacetimes).First, we generalize to arbitrary dimensions the holographic mechanism of chronology protection in the absence of gravitational backreaction.The AdS geometry dual to a conformal f

Pelvic circumferential compression devices for prehospital management of suspected pelvic fractures: a rapid review and evidence summary for quality indicator evaluation

Abstract Background Pelvic fractures, especially when unstable, may cause significant haemorrhage.The early application of a pelvic circumferential compression device (PCCD) in patients with suspected pelvic fracture has established itself as best practice.Ambulance services conduct corresponding performance measurement.Quality indicators (QIs) are
