Migration of Active Rings in Porous Media [PDF]
Phys. Rev. E 106, 014504, (2022), 2021 Inspired by how the shape deformations in active organisms help them to migrate through disordered porous environments, we simulate active ring polymers in two-dimensional random porous media. Flexible and inextensible active ring polymers navigate smoothly through the disordered media.

Bloch Waves in Crystals and Periodic High Contrast Media [PDF]
, 2016 Analytic representation formulas and power series are developed describing the band structure inside periodic photonic and acoustic crystals made from high contrast inclusions. Central to this approach is the identification and utilization of a resonance

Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]
, 2017 Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

Invariant imbedding theory of wave propagation in arbitrarily inhomogeneous stratified bi-isotropic media [PDF]
J. Opt. 18 (2016) 065605, 2016 Bi-isotropic media, which include isotropic chiral media and Tellegen media as special cases, are the most general form of linear isotropic media where the electric displacement and the magnetic induction are related to both the electric field and the magnetic intensity.

Contrast-induced nephropathy (CIN) - epidemiology, risk factors and prevention
Journal of Education, Health and Sport, 2022 Introduction: Contrast-induced nephropathy is one of the most serious adverse effects of radiocontrast agents usage. It is currently listed in the literature as the third most common cause of iatrogenic acute kidney injury.

Head-Neck Dual-energy CT Contrast Media Reduction Using Diffusion Models [PDF]
arXiv, 2023 Iodinated contrast media is essential for dual-energy computed tomography (DECT) angiography. Previous studies show that iodinated contrast media may cause side effects, and the interruption of the supply chain in 2022 led to a severe contrast media shortage in the US.
