A Grid-constrained Fourier Neural Operator for Magnetic Field Extrapolation of the Solar Corona

The Astrophysical Journal
In this study, we propose a hybrid architecture for coronal magnetic field extrapolation modeling. This architecture integrates Fourier neural operators (FNOs) with grid-based finite-difference methods used to impose physical constraints and is named ...

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

Journal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of
