Relativistic Positioning Systems in Flat Space-Time with Inertial, Hyperbolic and Rotating Emitters
UniverseWe analyse different configurations of four emitters in a Relativistic Positioning System (RPS) with: (i) one inertial and three static emitters, (ii) one hyperbolic and three static emitters, and (iii) three rotating and one static emitter.

Reserves, Injury Severity, and Outcomes in Traumatic Brain Injury: A CENTER‐TBI Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Reserve refers to the brain's ability to maintain function after an injury and strongly relates to traumatic brain injury (TBI) outcomes. This study examined (1) whether associations between pre‐injury reserve proxies and outcomes differed across injury severity categories, and (2) whether the impact of injury severity varied across ...
