Sampling of non‐Gaussian Ensemble Average Propagators for the simulation of diffusion magnetic resonance images

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1255-1265, February 2026.
Abstract Purpose (a) To design a methodology for drawing random samples of any Ensemble Average Propagator (EAP) (b) to modify the KomaMRI simulator to accommodate them as realistic spin movements to simulate diffusion MRI (dMRI) and (c) to compare these simulations with those based on the Diffusion Tensor (DT) model.

An Extended Krylov Subspace Method for Decoding Edge‐Based Compressed Images by Homogeneous Diffusion

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT The heat equation is often used to inpaint dropped data in inpainting‐based lossy compression schemes. We propose an alternative way to numerically solve the heat equation by an extended Krylov subspace method. The method is very efficient with respect to the computation of the solution of the heat equation at large times.

Definition and Computation of Tensor‐Based Generalized Function Composition

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT Functions are fundamental to mathematics as they offer a structured and analytical framework to express relations between variables. While scalar and matrix‐based functions are well‐established, higher‐order tensor‐based functions have not been as extensively explored.

Evaluating Model‐Based Extrapolation of Plasma Exposure for Long‐Acting Injectable Products: From Single‐ to Multiple‐Dose Trials

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 2, February 2026.
ABSTRACT Long‐acting injectable medicinal products (LAIs) prolong drug release and thereby aim to enhance adherence and patient outcomes. European regulatory guidelines require the conduct of single‐ and multiple‐dose trials to exclude differences in drug release between non‐steady and steady state conditions. The complexity of these trials may however
