Given the complexity of earthquake forecast and the current limitations in the application of artificial intelligence (AI), we propose a conceptual framework for a novel AI system, HuiShangGPT, intended to act as an expert in discussion on the trend of seismicity. This system, still in the conceptua...

Thyristor controlled phase shifting transformer (TCPST) is a new type of power flow control equipment. Due to its series and shunt coupling topology and special connection to the power grid, it is necessary to consider the handling strategy in case of power grid faults. Based on the structure and pr...

The axial resolution of optical coherence tomography (OCT) is determined by the spectral shape and bandwidth of the detected light, which are limited by the gaps in the wavelength range of illumination, transmission, and detection. In this paper, we demonstrate that the axial resolution deteriorated...

Phase-shifting transformers play a crucial role in power grid stability and efficiency. They adjust phase differences between loads, improve transmission efficiency, and balance loads during large-scale power transmission and grid integration. However, traditional mechanical phase-shifting transform...

Abstract Short large‐amplitude magnetic structures (SLAMS) play a fundamental role in the formation and energy conversion of the collisionless shock. Nevertheless, the evolution and the ion dynamics inside SLAMS are still unclear. In this study, we performed a superposed analysis of SLAMS near the E...
