Introducing relativity in global navigation satellite systems
Annalen der Physik, 2007 AbstractToday, the Global Navigation Satellite Systems, used as global positioning systems, are the GPS and the GLONASS. They are based on a Newtonian model and hence they are only operative when several relativistic effects are taken into account. The most important relativistic effects (to order 1/c2) are: the Einstein gravitational blue shift effect

Advancing Stroke Clinical Trials Using Community Engagement and Implementation Science Approaches
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Stroke clinical trials are essential for advancing stroke care but can face challenges with recruitment, retention, clinical relevance, and translation into real‐world practice. We propose that integrating community engagement and implementation science approaches into stroke trials can help address these needs.
