Look‐up table correction for beam hardening‐induced signal of clinical dark‐field chest radiographs
Medical Physics, Volume 53, Issue 2, February 2026.Abstract Background The microstructure of material at a μm$\,\umu\mathrm{m}$ length scale leads to ultra‐small‐angle scattering of X‐rays, which typically occurs, e.g., for lung tissue or some plastic foams. When using an interferometer, this effect alters the visibility of the fringe pattern, which can be detected and resolved by the detector.

Annals of West University of Timisoara: Physics, 2019 We have explored the effectiveness of Geant4 by using it to simulate phonon conduction in Sn Host with Si Nanowire Interface. Our Monte Carlo Simulation shows that the effectiveness of the phonon conduction Geant4 simulation increases when the system ...

Enabling comparison of UrQMD with Geant4 hadronic models
, 2010 Geant4 has an abundant set of physics models that handle the diverse interaction of particles with matter across a wide energy range. However, there are also many well established reaction codes currently used in the same fields where Geant4 is applied ...

On the role of secondary pions in spallation targets [PDF]
, 2016 We use particle-transport simulations to show that secondary pions play a crucial role for the development of the hadronic cascade and therefore for the production of neutrons and photons from thick spallation targets.

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.
