Cartesian MaxGIRF: Model‐based EPI reconstruction incorporating gradient nonlinearity and concomitant field effects

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1044-1067, February 2026.
Abstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.

Frequency‐Dependent Diffusion–Relaxation Distribution MRI: Scan–Rescan Reproducibility Ex Vivo and Caveats

NMR in Biomedicine, Volume 39, Issue 2, February 2026.
Frequency‐dependent multidimensional (ωMD) diffusion‐relaxation MRI captures microstructural information beyond conventional voxel‐averaged metrics. Here, we evaluate ωMD‐MRI reproducibility in ex vivo mouse brains using a high‐performance micro‐imaging system.

Machine Learning Approximations for Fast and Accurate Prediction of Nonlinear Four‐Wave Interactions in Spectral Wave Models

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Operational wave forecasting requires a delicate balance between the accuracy and computational speed of the spectral wave model used, in which the nonlinear wave–wave interaction “source” term plays an important role. The exact formulation of these nonlinear four‐wave interactions requires solving the six‐dimensional Boltzmann integral, an ...

Improvement of Seasonal Carbon Cycles in HNLC Regions of a Global Ocean Biogeochemical Model Using a Simple Marine Ecosystem Module

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract A recent community‐wide evaluation revealed that many state‐of‐the‐art global ocean biogeochemical models displayed seasonal surface CO2 ${\text{CO}}_{2}$ flux variations in the subpolar North Pacific that were out‐of‐phase with observation‐based estimates.

Semidiaphanam Tremuli Narcissuli Ideam Lacteam1: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

Archaeometry, Volume 68, Issue 1, Page 120-131, February 2026.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
