Recent progress on flutter‐based wind energy harvesting
International Journal of Mechanical System Dynamics, 2022 Wind energy harvesting technology can convert wind energy into electric energy to supply power for microelectronic devices. It has great potential in many specific applications and environments, such as remote areas, sea surfaces, mountains, and so on ...

Thinner biological tissues induce leaflet flutter in aortic heart valve replacements
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Percutaneous valve replacement procedures enable the deployment of bioprosthetic heart valves through a catheter, which offers a minimally invasive option to treat valvular heart disease. Although these bioprostheses typically employ thinner

Electrophysiological Mechanisms of Atrial Flutter [PDF]
, 2006 Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about
