Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,

Laterally Oscillating Trajectory for Undersampling Slices: LOTUS

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1682-1695, October 2026.
ABSTRACT Purpose While spiral sampling offers SNR advantages for diffusion MRI, its acceleration with simultaneous multislice remains relatively unexplored. This study introduces Laterally Oscillating Trajectory for Undersampling Slices (LOTUS), which is a 3D spiral‐like k‐space trajectory that aims to minimize g‐factor via controlled incoherent ...

Evaluating Human Perception Thresholds in Magnetic Stimulation Using Experimental Measurements and Modelling

open access: yesBioelectromagnetics, Volume 47, Issue 6, September 2026.
ABSTRACT This preregistered study investigated whether induced electric fields alone could predict human perception thresholds in magnetic stimulation. Using a figure‐of‐eight magnetic coil placed on the forearm, perception thresholds were collected from 24 healthy participants using the method of adjustment in 12 stimulation conditions. Subject‐fitted,
