Tropospheric scintillation on Earth-space paths greatly increases at low elevation angles and/or higher carrier frequencies, may impair low margin systems, and can interfere with the power control ...

In two recent studies, researchers suggest a weakening ocean current system is to blame for a persistent cold spot in the ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...
