Surgical Aortic Valve Replacement Following Transcatheter Aortic Valve Implantation Degeneration in a Patient with Prior David Procedure: A Case Report

The Thoracic & Cardiovascular Surgeon Reports
This is the first reported case of a self-expanding aortic valve explanted from the ascending aorta consisting of a Dacron prosthesis. We describe a 75-year-old male with bicuspid aortic valve regurgitation initially treated with a David procedure ...

Cooperative and non-cooperative solutions to carbon leakage [PDF]

A modified version of the CGE GTAP-E model is developed for assessing the economic and carbon emissions effects related to alternative policy measures implemented with the aim of reducing carbon leakage. We explore a set of scenarios, comparing solutions

Effective Modeling of Leakage Inductance for use in Circuit Simulation

, 2008
Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known

Carbon Leakage, the Green Paradox and Perfect Future Markets [PDF]

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or ...
