A small scale energy harvester from wind induced vibrations by Abdel-Fattah, Ahmed Sayed Ahmed

“…The device consists of a cantilever beam with the free end attached to a square section box that is subjected to the air stream inducing aero-elastic flutter. Flutter is a coupled torsion, plunge instability that has been historically studied to be avoided by aerospace and civil engineers. …”

A spectral and timing study of MAXI J1820+070 during outburst by Solomons, Kyle

“…The transfer of matter can occur through continuous donor supply or episodic capturing of material from stellar winds, leading to sudden enhancements in X-ray flux known as outbursts. The instabilities in the disk, the geometry of the inner disk, the coupling between the disk and corona, etc, also contribute to the observed variability. …”
