Abstract: A unique architecture of Sentinel-3A and Sentinel-3B satellites includes the shared ultra-stable oscillator (USO) by the DORIS and GPS receivers. This concept enables to apply onboard GPS clock estimates in the DORIS processing substituting the… read more here.

Abstract: A wide range of divergence times is supported by birth-death models under constant rates of speciation and extinction. Molecular evolutionary time scales are expected to predate the fossil evidence, but, particularly for major evolutionary radiations,… read more here.
