Abstract: This paper investigates a drone (aka UAV)-assisted physical layer security framework for space–air–ground integrated networks (SAGINs) in the presence of multiple eavesdroppers. A single ...
Abstract: This paper examines the possibility of applying scale models for electromagnetic fields to the air-freshwater two-layer problem. Since the conductivity of freshwater is small, a conventional ...
In A Nutshell Penn State scientists captured the first direct evidence of trees producing faint electrical glows, called coronae, during live thunderstorms. The discharges hop erratically from leaf to ...
