Electrophysiological Mechanisms of Atrial Flutter [PDF]
Indian Pacing and Electrophysiology Journal, 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

Incremental healthcare cost burden in patients with atrial flutter only
Frontiers in Cardiovascular Medicine, 2023 BackgroundLimited information is available on the costs related to atrial flutter only. This study provides a comprehensive estimate of the cost in patients with atrial flutter only versus matched patients without any atrial arrhythmia.MethodsPatients ...

Applied Sciences, 2020 Recently, the nonlinear flutter behavior of long-span suspension bridges has attracted attention. Unlike the classical theory of bridge flutter, the stable limit cycle oscillations (LCO) have occurred for some bluff aerodynamic configurations when the ...

Current Biology, 2005 For many conservationists, butterflies are some of the key species that can indicate the quality of an environment not only for themselves but for many other, often less visible, species. Some of their specific needs are often well known, but movements around their habitat and important factors within it are less understood. To help address this issue,

Buildings, 2022 In order to study the relationship between an aerostatic three-component coefficient (ATCC) and bridge flutter and to quickly evaluate the flutter performance of bridges, we proposed a method based on the empirical formula of the ATCC.

Aeroelastic analysis and flutter control of wings and panels: A review
International Journal of Mechanical System Dynamics, 2021 Flutter is a self‐excited vibration under the interaction of the inertial force, aerodynamic force, and elastic force of the structure. After the flutter occurs, the aircraft structures will exhibit limit cycle oscillation, which will cause catastrophic ...

Current Biology, 2003 The fluttering flight of butterflies is characteristic of these insects but belies the fact that most species are competent or strong fliers with several members carrying out spectacular migrations. However, new work by a team led by Angel Viloria based at the Natural History Museum in London, report in the Proceedings of the Royal Society published ...

Suppression of Bridge Flutter Using Suction Control
Advances in Civil Engineering, 2021 To verify the effectiveness of the suction-based method for improving flutter stability of long-span bridges, the forced vibration experiments for extracting the flutter derivatives of a section model with and without suction were performed, and the ...

Stall Flutter Control of a Smart Blade Section Undergoing Asymmetric Limit Oscillations
Shock and Vibration, 2016 Stall flutter is an aeroelastic phenomenon resulting in unwanted oscillatory loads on the blade, such as wind turbine blade, helicopter rotor blade, and other flexible wing blades.

Current Biology, 2003 AbstractReports last month of the first cloned horse by researchers in Cremona, Italy – home of some of the finest violin makers – put the racing community into a spin, but they have little to fear from this experiment, writes Michael Gross.
