Validating the standard model of diffusion MRI in white matter with numerical substrates

Published on 2026-10-15 by @MIT

Abstract: AbstractThe non-invasive estimation of intra- and extracellular microstructural parameters using biophysical models has been a major focus in brain microstructure imaging with MRI. The Standard Model (SM) of diffusion in white matter (WM) provides a unifying framework for various modelling approaches, representing axons as impermeable sticks embedded within a locally anisotropic extra-axonal space. However, the SM relies on simplifying assumptions that may not hold in realistic WM tissue, as the[...]


Our summary: This study validates the Standard Model of diffusion MRI in white matter using realistic numerical substrates. It examines how various axonal features and conditions affect parameter estimates derived from the model. The findings help identify biases in interpretations based on varying microstructural conditions.

Two-dimensional beam compression for sub-femtosecond electron beam generation

Published on 2026-09-21 by Weihang Liu, Shimin Jiang, Xiao Li, Xingguang Liu, Yi Jiao and Sheng Wang @IOP SCIENCE

Abstract: Sub-femtosecond electron beams are powerful probes of ultrafast electronic, atomic, and nuclear dynamics, and promising drivers for ultrashort radiation generation from the extreme-ultraviolet to gamma-ray regimes. However, producing such beams at hundred-MeV energies with pC-level charge remains challenging. Here wedevelop a two-dimensional beam-compression scheme based on transverse–longitudinal coupling, in which dispersive beam optics convert the small transverse emittance of modern electr[...]


Our summary: A two-dimensional beam-compression scheme is developed for generating sub-femtosecond electron beams.

Effects of cosmic-ray muons on ? eV-to-meV scale axion dark matter searches

Published on 2026-09-01 by Dan Zhang, Gray Rybka, Edward J Daw and Robyn Evren @IOP SCIENCE

Abstract: We estimate the synchrotron radiation emitted by cosmic-ray muons in a uniform magnetic field, focusing on the photon radiation from eV to meV. Such events can potentially bring backgrounds to the axion dark matter searches. The GEANT4 software package is utilized to simulate the muon tracks in a cylindrical region of interest with an 8 T solenoid magnetic field applied. We further develop an analytical estimation of the angular-frequency-differential synchrotron radiation power spectra in this [...]


Our summary: This study estimates synchrotron radiation from cosmic-ray muons in a magnetic field relevant to axion dark matter searches. Simulations using GEANT4 show that cosmic-ray muons do not dominate noise backgrounds for current eV-scale experiments. Future broadband axion dark matter searches may be affected by synchrotron radiation if energy resolution is insufficient.
