Steady-state spherical tokamak power reactor with high-temperature-superconductor

Nuclear Fusion
A spherical tokamak (ST) with an internal transport barrier (ITB) has the potential to be an ideal fusion power reactor because it not only offers high β performance and blanket replaceability, but also enables self-sustaining operation through a high ...

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion

International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1541-1557, December 2025.
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

The Solar Wind Interaction With an Orbiting Venus

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Studies of the large‐scale interaction of the solar wind with planets have often been considered along the line of the sun to the planet, neglecting the planet's orbital motion. This paper describes a new refinement in the long history of Venus simulations, the addition of the planet's orbital motion.
