Lightning Detection and Imaging Based on VHF Radar Interferometry

In this study, detection and three-dimensional (3D) imaging of lightning plasma channels are presented using radar interferometry.Experiments were carried out in Leshan, China with a 48.2 MHz VHF radar configured with an interferometric antenna array.The typical characteristics of lightning echoes are studied in the form of amplitude, phase, and do

Signatures of criticality in turning avalanches of schooling fish

Moving animal groups transmit information through propagating waves or behavioral cascades, exhibiting characteristics akin to systems near a critical point from statistical physics.Using data from freely swimming schooling fish in an experimental tank, we investigate spontaneous behavioral cascades involving turning avalanches, where large directi
