Near field pressure fluctuations of an elliptic jet
8th Aeroacoustics Conference, 1983 Author(s): Gutmark, E; Ho, CM | Abstract: The near-field pressure fluctuations of an elliptic jet were experimentally investigated in this work. The characteristics of the fluctuating pressure were found to be only slightly different in the two planes containing the major and minor axes.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
