FOR a decade or more the propagation of radio waves far beyond the horizon in the very high-frequency, ultra high-frequency and super high-frequency bands, together with their characteristic fast ...

"The mechanism of ultra-low-energy defibrillation we uncovered exploits this sensitivity. Varying the electrical field profile over a relatively long time interval allows blocking the propagation ...
