Lateral Deformation of Large-scale Coronal Mass Ejections during the Transition from Nonradial to Radial Propagation

Huidong Hu, Yiming Jiao, Bei Zhu, Xiaowei Zhao et autres

Abstract Many coronal mass ejections (CMEs) initially propagate nonradially, and then transition to radial propagation in the corona. This directional transition is a significant process that determines a CME’s space weather effects but remains poorly understood. Based on multiwavelength observations, we investigate …

Inertial-range Turbulence Anisotropy of the Young Solar Wind from Different Source Regions

Wenshuai Cheng, Ming Xiong, Yiming Jiao, Hao Ran et autres

Abstract We investigate the wavevector and variance anisotropies in the inertial range of the young solar wind observed by the Parker Solar Probe (PSP). Using the first 19 encounters of PSP measurements, we identify the young solar wind from different source regions: …

ML385 promotes ferroptosis and radiotherapy sensitivity by inhibiting the NRF2-SLC7A11 pathway in esophageal squamous cell carcinoma

Ling Yan, Huidong Hu, Lei Feng, Zhe Li et autres

Radiotherapy is important in treating esophageal squamous cell carcinoma (ESCC) comprehensively. Resistance to radiotherapy is a prominent factor contributing to treatment failure in patients with ESCC. The objective of this study was to investigate the impact of ML385, an inhibitor of nuclear …

Limb Observations of Global Solar Coronal Extreme-ultraviolet Wavefronts: The Inclination, Kinematics, Coupling with the Expanding Coronal Mass Ejections, and Connection with the Coronal Mass Ejection Driven Shocks

Huidong Hu, Bei Zhu, Ying D. Liu, Chong Chen et autres

Abstract We select and investigate six global solar extreme-ultraviolet (EUV) wave events using data from the Solar Dynamics Observatory and the Solar and Heliospheric Observatory. These eruptions are all on the limb but recorded as halo coronal mass ejections (CMEs) because the …

High-resolution Observations of Clustered Dynamic Extreme-Ultraviolet Bright Tadpoles Near the Footpoints of Corona Loops

Rui Wang, Ying D. Liu, L. P. Chitta, Huidong Hu et autres

Abstract An extreme ultraviolet (EUV) close-up view of the Sun offers unprecedented detail of heating events in the solar corona. Enhanced temporal and spatial images obtained by the Solar Orbiter during its first science perihelion enabled us to identify clustered EUV bright …

A Pileup of Coronal Mass Ejections Produced the Largest Geomagnetic Storm in Two Decades

Ying D. Liu, Huidong Hu, Xiaowei Zhao, Chong Chen et autres

Abstract The largest geomagnetic storm in two decades occurred in 2024 May with a minimum D st of −412 nT. We examine its solar and interplanetary origins by combining multipoint imaging and in situ observations. The source active region, NOAA AR 13664, …

The largest geomagnetic storm in two decades occurred in 2024 May with a minimum $D_{\rm st}$ of $-412$ nT. We examine its solar and interplanetary origins by combining multipoint imaging and in situ observations. The source active region, NOAA AR 13664, exhibited …

Identification of key genes and long non‑coding RNA expression profiles in osteoporosis with rheumatoid arthritis based on bioinformatics analysis

Jinyu An, Xing-na Ma, Hui-long Wen, Huidong Hu

BACKGROUND: Although rheumatoid arthritis (RA) is a chronic systemic tissue disease often accompanied by osteoporosis (OP), the molecular mechanisms underlying this association remain unclear. This study aimed to elucidate the pathogenesis of RA and OP by identifying differentially expressed mRNAs (DEmRNAs) and …

Establishment and Application of an Interplanetary Disturbance Index Based on the Solar Wind–Magnetosphere Energy Coupling Function and the Spectral Whitening Method

Xiaowei Zhao, Jingsong Wang, Ming‐Xian Zhao, Ying D. Liu et autres

Abstract We develop a preliminary interplanetary disturbance index (J s W ) by applying the spectral whitening method to an energy coupling function with solar wind measurements during the years 1998–2014 as the input, which can be used as an indicator of …
