Multifrequency Multiparameter Magnetic Resonance Elastography Applied to an In Vivo Porcine Model for Assessing Portal Hypertension

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
Portal hypertension, a critical complication in chronic liver disease, has long relied on invasive hepatic venous pressure gradient measurement for definitive diagnosis. This study establishes that multifrequency three‐dimensional magnetic resonance elastography (3D‐MRE) can noninvasively quantify portal pressure, with splenic stiffness and loss ...

The stratospheric gravity wave field produced by a supercell

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Supercells are a class of long‐lasting thunderstorms with rotating updrafts that often cause severe weather, hail, and tornadoes. This study uses numerical simulations to characterize the stratospheric gravity waves that are caused by these storms.

A pilot variational coupled reanalysis based on the CESAM climate model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.
