Effect of Modulation on Energy Conversion from Uniform Flow into Vortex-Induced Vibration of a Circular Cylinder

Journal of Fluid Science and Technology, 2013
We conducted an experiment to investigate the vortex-induced vibration (VIV) of an elastically supported rigid cylinder in fluid flow in order to develop a renewable energy system that utilizes the VIV.

Valve-in-valve procedures for degenerated surgical and transcatheter aortic valve bioprostheses using a latest-generation self-expanding intra-annular transcatheter heart valve

Frontiers in Cardiovascular Medicine, 2023
BackgroundValve-in-valve (ViV) transfemoral transcatheter aortic valve implantation (TAVI) for failing aortic surgical bioprostheses or transcatheter heart valves (THV) has demonstrated a reasonable clinical and hemodynamic efficacy.

Hydro‐ and Lipophilicity of Molecular‐Size‐Controlled Hydrogel Drug Carriers

Advanced Materials Technologies, EarlyView.
We investigate nano‐sized hydrogel drug carriers with tailored hydro‐ and lipophilicity. We design their encapsulation and structure‐forming capabilities and follow them in real time during fabrication using time‐resolved and in situ grazing incidence x‐ray scattering.

Valve-in-valve/valve-in-ring transcatheter mitral valve implantation vs. redo surgical mitral valve replacement for patients with failed bioprosthetic valves or annuloplasty rings: A systematic review and meta-analysis

Heliyon, 2023
Background: Valve-in-valve (ViV)/valve-in-ring (ViR) transcatheter mitral valve implantation (TMVI) is a less invasive alternative to redo surgical mitral valve replacement (SMVR).

Ramp Tests: A Novel Approach to VIV Model Testing of Flexible Cylinders Using Continuously Varying Towing Speeds [PDF]

, 2015
In this paper we present a small portion of the results from the 2011 SHELL tests at the MARINTEK basin. The tests involved towing densely instrumented flexible cylinders at Reynolds numbers up to 150,000 in order to study the Vortex-Induced Vibration ...

Potential‐Controlled Ammonium‐Assisted Reversible Electrodeposition of Polyoxometalates for Hybrid Redox Flow Batteries

Advanced Science, EarlyView.
Potential‐controlled NH4+‐assisted reversible electrodeposition of molecular metal oxide clusters enables dynamic solution‐to‐solid electron storage. Leveraging this deposition/dissolution reaction chemistry, polyoxometalate‐based hybrid flow batteries are demonstrated as a new platform for deposition‐based electrochemical energy storage.

Experimental study on vortex induced vibration of risers with fairing considering wake interference

International Journal of Naval Architecture and Ocean Engineering, 2017
Vortex Induced Vibration (VIV) is a typical flow-structure interference phenomenon which causes an unsteady flow pattern due to vortex shedding at or near the structure's natural frequency leading to resonant vibrations.

Hemodynamic and Clinical Outcomes in Redo-Surgical Aortic Valve Replacement vs. Transcatheter Valve-in-Valve

Structural Heart, 2022
Background: Transcatheter valve-in-valve replacement (ViV-TAVR) has emerged as an alternative to redo-surgical aortic valve replacement (Redo-SAVR) for the treatment of failed surgical aortic bioprostheses.
