Real-time LEO satellite clock estimation with predicted LEO satellite orbits constrained

GPS Solutions
Low Earth Orbit (LEO) satellites can augment the traditional GNSS-based positioning, navigation and timing services, which require real-time high-precision LEO satellite clock products. As the complicated systematic efects contained in the LEO satellite clock estimates limit their high-precision mid- to long-term prediction, high-frequency LEO ...

Structural Basis of Lymphangiogenic Receptor VEGFR‐3 Activation Mediated by Distinctive Clustering of the Ligand–Receptor Complex

Advanced Science, EarlyView.
VEGF‐C and its receptor VEGFR‐3 are critical for lymphangiogenesis. Cryo‐EM structures of the VEGFR‐3/VEGF‐C ectodomain complex reveal a canonical 2:2 ligand–receptor hetero‐tetramer that further assembles into higher‐order clusters beyond simple receptor dimerization.
