AbstractThe drift motion of energetic charged particles can generate an azimuthal electric current around the planet known as the ring current, which regulates the field configuration of the magnetosphere. However, limited coverage of in-situ measurements makes it challenging to investigate the long-term variations of the global ring current.

Topics Plasma impurities, Plasma transport properties, Plasma turbulence, Tokamaks, Magnetic confinement fusion, Turbulent flows The physics of edge plasma in magnetic fusion devices is multifaceted and complex (e.g., see Ref. 1 and the references therein). Even though it has already been studied for a long time, there are still many open issues, including anomalous edge plasma transport, which plays a key role in edge plasma physics.

Abstract:As one of foundation technologies for massive data processing for AI, event mining is attracting more and more attention, mainly including event detection (event trigger identification and event classification) and argument extraction. At present, EE-GCN is one of the most effective methods for event detection. However, since EE-GCN only focuses on event detection, complete event multi-tuple extraction needs to be improved.
