Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI
Chemie Ingenieur Technik, EarlyView.This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
The Canadian Journal of Chemical Engineering, EarlyView.This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Source-time dominant modeling of the Doppler shift for the auralization of moving sources
Acta AcusticaWhen developing an auralization for acoustic scenarios involving moving sources and receivers, one key feature is the ability to simulate the Doppler shift, i.e., the changing frequency content from the receiver’s perspective.

ESC Heart Failure, Volume 12, Issue 2, Page 888-899, April 2025.Abstract Aims Heart failure with preserved ejection fraction (HFpEF) continues to be an increasingly common health problem associated with a high mortality rate. Elevated levels of Growth differentiation factor‐15 (GDF15) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) are reportedly associated with poor clinical outcomes in a broad range of ...

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Considerations for drug trials in hypertrophic cardiomyopathy
ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.
