CFD: computational fluid dynamics or confounding factor dissemination? The role of hemodynamics in intracranial aneurysm rupture risk assessment.

Image-based computational fluid dynamics holds a prominent position in the evaluation of intracranial aneurysms, especially as a promising tool to stratify rupture risk. Current computational fluid dynamics findings correlating both high and low wall shear stress with intracranial aneurysm growth and rupture puzzle researchers and clinicians alike. These conflicting findings may stem from incon...

Vitamin D in endometriosis: a causative or confounding factor?

OBJECTIVE The aim of this paper is to review the evidence from studies that evaluated the relationship between vitamin D and endometriosis. DESIGN Comprehensive review. MATERIALS AND METHODS Systematic literature search in Medline for relevant publications from 1946 until June 2013. RESULTS Endometriosis risk may be influenced by dietary vitamin D intake and plasma hydroxyvitamin D concen...

Computational Fluid Dynamics: Science or Toolbox?

Over the past six decades the science of CFD has created a versatile computational toolbox. Still, enough barriers remain; for aeronautical CFD one of the highest ones is slow convergence to steady flow solutions. The importance of reducing method complexity to O(N) is discussed in the light of future massively parallel computing. In the same light a vision is outlined of CFD based on PDEs of t...
