Abstract: The accelerated calving of ice shelves buttressing the Antarctic Ice Sheet may form unstable ice cliffs. The marine ice cliff instability hypothesis posits that cliffs taller than a critical height (~90 m) will undergo structural… read more here.

Abstract: An ordinary high frequency radio wave radiated at the Spitze angle after reflection from the ionosphere does not return to the ground. It is converted into the Z-mode, and in the vicinity of the critical… read more here.
