First application of the island divertor configuration in the J-TEXT tokamak

Nuclear Fusion
For the first time, an island divertor configuration was successfully implemented in the J-TEXT tokamak to improve heat exhaust and impurity control. The magnetic island is generated by applying external resonant magnetic perturbation fields, and the ...

Curvature-induced singularities and stability analysis of curved perfectly matched layers for ICRF antenna–plasma coupling

Nuclear Engineering and Technology
In electromagnetic modeling of ion cyclotron range of frequencies (ICRF) antennas, curved coupling models provide a more realistic representation of the antenna and edge-plasma geometry, improving the accuracy of wave-coupling and loading predictions ...

On The Confinement of a Tokamak Plasma [PDF]

SIAM Journal on Mathematical Analysis, 2010
The goal of this paper is to understand from a mathematical point of view the magnetic confinement of plasmas for fusion. Following Frénod and Sonnendrücker \cite{FS2}, we first use two-scale convergence tools to derive a gyrokinetic system for a plasma submitted to a large magnetic field with a slowly spatially varying intensity.

Efficient light confinement to λ/10 spot sizes in optical fibre

Light confinement beyond the diffraction limit has been achieved in optical fibre tips. We successfully fabricated a gold-coated optical fibre tip with wedge-shaped apex for the efficient excitation of surface plasmon polaritons (SPPs).

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

New Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Magnetic-island induced geometric stabilization of turbulence triggering eITB bifurcation

Nuclear Fusion
We demonstrate that geometric deformation of flux-surface induced by a magnetic island can trigger the bifurcation to an electron internal transport barrier (eITB) through a novel positive feedback loop arising from the nonlinear coupling between the ...

Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing–Remitting MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels are believed to reflect mainly acute and chronic disease processes in multiple sclerosis (MS), respectively. In this study, we investigated whether dimethyl fumarate (DMF) and rituximab (RTX) differentially affect these biomarkers.
