Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Dose‐Dependent Effects of Biochar on Soil Revealed by Fast Field‐Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 349-364, March 2026.
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

High‐resolution deuterium metabolic imaging of the human brain at 9.4 T using phase‐cycled balanced SSFP spectral–spatial acquisitions

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1304-1322, March 2026.
Abstract Purpose The aim was to improve the sensitivity and robustness against B0 inhomogeneities of deuterium metabolic imaging (DMI) using phase‐cycled balanced SSFP (bSSFP) methods at 9.4 T. Methods We investigated two variants of phase‐cycled bSSFP acquisitions, namely uniformly weighted multi‐echo and acquisition‐weighted chemical shift imaging ...

Comparison of Analytical and FFT‐Based Predictions of Effective Stiffness in Isotropic and Anisotropic Closed‐Cell Materials

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT This work investigates the elastic behavior of isotropic and anisotropic closed‐cell porous materials using analytical and Fast‐Fourier‐Transform (FFT)‐based numerical approaches. The study focuses on understanding how microstructural features, such as pore shape, orientation, and solid volume fraction, influence the macroscopic stiffness of ...
