Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]

, 2011
In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.

Agreement between Murray law-based quantitative flow ratio (μQFR) and three-dimensional quantitative flow ratio (3D-QFR) in non-selected angiographic stenosis: A multicenter study

Cardiology Journal, 2022
BACKGROUND: The agreement between single-projection Murray-based quantitative flow ratio (mQFR) and conventional three-dimensional quantitative flow ratio (3D-QFR) has not been reported hitherto.

Residual quantitative flow ratio to estimate post-intervention fractional flow reserve [PDF]

European Heart Journal, 2021
Abstract Objective To assess the performance of residual quantitative flow ratio (QFR) to estimate post percutaneous coronary intervention (PCI) fractional flow reserve (FFR). Background QFR computes FFR based on invasive coronary ...

The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

Validation of Quantitative Flow Ratio-Derived Virtual Angioplasty with Post-Angioplasty Fractional Flow Reserve—The QIMERA-I Study

Journal of Cardiovascular Development and Disease, 2023
Background: Quantitative flow ratio (QFR) virtual angioplasty with pre-PCI residual QFR showed better results compared with an angiographic approach to assess post-PCI functional results.
