Modeling Liquid‐Mediated Interactions for Close‐to‐Substrate Magnetic Microparticle Transport in Dynamic Magnetic Field Landscapes

Particle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.
The trajectory of a single magnetic particle moving close to a polymer surface in a tailored magnetic field landscape surrounded by a static fluid is quantified using an adjustable simulation model. Varying simulation parameters give insights in key properties of magnetic particle‐based Lab‐on‐a‐chip systems for medical diagnostics.

Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

Calibrated Granular‐Flow PIV From DEM Simulations: Flow‐Substrate Dynamics in Flows With Fixed and Erodible Substrates, Modeling, and Field Implications

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Granular flows are central to geophysical and industrial processes, yet their internal properties remain difficult to quantify. Understanding how energy and momentum are exchanged at the flow–substrate boundary is key to predicting their erosion and mobility.

Micro-expression motion magnification: global lagrangian vs. local Eulerian approaches

, 2018
Micro-expressions are difficult to spot but are utterly important for engaging in a conversation or negotiation. Through motion magnification, these expressions become much more distinguishable and easily recognized.

Time‐resolved imaging of electron beam powder bed fusion using an X‐ray microscope optimized for white beam radiation

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 181-194, January 2026.
A high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...

Modelling Wetting Collapse, Failure and Deposition of an Unsaturated Slope With Material Point Method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4526-4551, 25 December 2025.
ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...
