Experimental investigation on effect of ion cyclotron resonance heating on density fluctuation in SOL at EAST

Nuclear Engineering and Technology, 2022
The suppression of high-intensity blob structures in the scrape-off layer (SOL) by ion-cyclotron range of frequencies (ICRF) power, leading to a decrease in the turbulent fluctuation level, is observed first in the Experimental Advanced Superconducting ...

Observation of electrostatic fluctuations driven by runaway electrons in EAST disruptions

Nuclear Fusion, 2023
Electrostatic fluctuations driven by runaway electrons (REs) have been observed following a thermal quench during Experimental Advanced Superconducting Tokamak–intended disruptions, which are triggered by massive gas injection. Electrostatic fluctuations

Fast equilibrium reconstruction by deep learning on EAST tokamak

AIP Advances, 2023
A deep neural network is developed and trained on magnetic measurements (input) and EFIT poloidal magnetic flux (output) on the EAST tokamak. In optimizing the network architecture, we use automatic optimization to search for the best hyperparameters ...

Confinement of fast ions in east tokamak

Acta Physica Sinica, 2006
The three well-known parameters of motion (magnetic momentum, energy and canonical toroidal momentum) are utilized to develop a guiding center orbit code, GCORBIT. The effect of poroidal field ripple and toroidal angle scatter is considered in the GCORBIT.

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.

Data readiness pipeline patterns for scientific AI at scale: Insights from climate, fusion, life sciences, and materials

AI Magazine, Volume 47, Issue 1, Spring 2026.
Abstract This article examines how data readiness for AI principles apply to large scientific datasets used to train foundation models. We analyze archetypal workflows across four representative domains—climate, nuclear fusion, life sciences, and materials—to identify common preprocessing patterns and domain‐specific constraints.

Relation between porosity‐based and crystal‐based femtosecond laser‐induced nanogratings in oxide glasses

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.
