Is the Instantaneous Wave-Free Ratio Equivalent to Fractional Flow Reserve?
Journal of the American College of Cardiology, 2013 We read the paper by Sen et al. [(1)][1] with great interest; the study was designed to explore whether the instantaneous wave-free ratio (iFR) was an adenosine-free alternative to fractional flow reserve (FFR) for the assessment of coronary stenosis.

Dilute neutron matter on the lattice at next-to-leading order in chiral effective field theory [PDF]
, 2008 We discuss lattice simulations of the ground state of dilute neutron matter at next-to-leading order in chiral effective field theory. In a previous paper the coefficients of the next-to-leading-order lattice action were determined by matching nucleon ...

Numerical analysis of the 3D flow induced by propagation of plane-wave deformations on thin membranes inside microchannels [PDF]
, 2007 Propulsion mechanisms of microorganisms are based on either beating or screw-like motion of thin elastic biopolymers. Arguably, this motion is optimal for propulsion at very low Reynolds numbers. Similar actuation mechanisms can be utilized in the design

Instantaneous Wave-Free Ratio: Novel Adenosine-Free Method to Assess Intracoronary Physiology
Turk Kardiyoloji Dernegi Arsivi-Archives of the Turkish Society of Cardiology, 2023 Fractional flow reserve assessment was accepted as a crucial strategy in stable patients undergoing coronary angiography without prior noninvasive evaluation in the presence of borderline lesions and in patients with multivessel coronary artery disease.
