Challenges and opportunities in improving left ventricular remodelling and clinical outcome following surgical and trans-catheter aortic valve replacement

Frontiers of Medicine 2021, Volume 15, Issue 3,   Pages 416-437 doi: 10.1007/s11684-021-0852-7

Abstract: Precise understanding of myocardial adaptation to pressure and volume overloading and its responses tosurgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance to myocardialactivation, force-velocity relationship, and myocardial strain.LV hypertrophy and myocardial fibrosis remains as the structural and morphological focus in this endeavour

On Scattering and Radiation Problem for a Cylinder over a Cylindrical Barrier in Water of Finite Depth

Wu Bijun,Zheng Yonghong,You Yage,Sun Xiaoyan,Chen Yong

Strategic Study of CAE 2004, Volume 6, Issue 2,   Pages 48-55

Abstract:

By use of an eigenfunction expansion method, the expressions for the properties of kinematics and kinetics, which are due to scattering and radiation for a floating vertical circular cylinder over a coaxial cylindrical barrier in water of finite depth, are derived in the presence of an incident linear waves. The radius of the barrier is larger than or equal to that of the floating vertical circular cylinder. This paper presents the analytical solution for the radiation potentials due to heave, surge, and pitch and for the diffraction potential due to the diffraction of an incident wave acting on the fixed cylinder. It also proposes a set of theoretical added masses, damping coefficients and exciting forces. The results of the expressions are the same as that of the cylinder over a cylindrical barrier, the radius of wich is the same as that of the cylinder, in water of finite depth for added masses, damping coefficients and exciting forces at the same condition. Two methods to calculate exciting forces are presented and the results of the methods are the same. Finally, Analytical results of added masses, damping coefficients and exciting forces are obtained for different size of the barrier.
