C. F. v. Weizsächer on Quasistationary Isotropic Turbulence Compared With Onsager's Statistical Hydrodynamics

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
v. Weizsäcker and Heisenberg began their turbulence collaboration in 1945 while still quarantined at Farm Hall. Their papers were submitted separately in 1946 from Göttingen. v. Weizsäcker had derived the 5/3 law for dissipation while using dimensional analysis in real space.

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

open access: yesParticle &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.

Space Correlation Constrained Physics Informed Neural Network for Seismic Tomography

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Physics‐informed neural networks (PINNs) integrate physical constraints with neural architectures and leverage their nonlinear fitting capabilities to solve complex inverse problems. Tomography serves as a classic example, aiming to reconstruct subsurface velocity models to improve seismic exploration.

A Model Intercomparison Study to Investigate Mixing Characteristics in Non‐Precipitating Stratocumulus Clouds

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Recent aircraft observations of marine stratocumulus clouds consistently showed that cloud microphysical relationships vary with altitude, indicating inhomogeneous mixing characteristics near cloud top and homogeneous mixing characteristics in mid‐levels of clouds.

A Generalized Framework for Flow Resistance in Canopies and Granular Beds

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract This study presents a generalized, theoretically grounded semi‐empirical framework for estimating flow resistance through canopies and granular beds, both of which are common in engineering and environmental applications. Derived from fundamental fluid mechanics principles, the proposed formulation significantly reduces reliance on empirical ...

Modeling Suffusion in Porous Media Using a Particle Scale Linear Decay Function

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Suffusion with migration of fine particles (fines) in pores is a common subsurface hydrological process in nature, which has significant impacts on breaching of dikes, dam failure, and hillslope instability. However, the effects of soil properties and hydrodynamic conditions on fines migration, and the physical implications of mass flow rates ...
