A GeV Gamma-Ray Spectral Excess in the Fermi Blazar 4FGL J0136.5+3906
Shi-Ju Kang, Yue Yin, Yong-Gang Zheng +2
We report the detection of a {19} GeV gamma-ray spectral excess (peak energy in observer frame) at 5.7 significance (3 degrees of freedom, without correction for tri…
The Evolution of Thermal and Non-thermal Emission Components in GRB 250920C
Jia-Ming Chen, Ke-Rui Zhu, Shan Chang +5
We present a temporal and time-resolved spectral analysis of GRB 250920C using \textit{Fermi}/GBM and \textit{Swift}/BAT data. The prompt emission consists of two distinct episodes…
Link prediction on multi-relational graphs from an influence propagation perspective
Zidu Yin, Yuankai Qi, Dong Gong +3
Predicting the existence and type of links (edges) between nodes in a multi-relational graph is key for applications from social interaction prediction to knowledge relationship id…
Prompt-Calibrated SAM 3 for Open-Vocabulary Remote Sensing Semantic Segmentation
Yanghui Song, Nanqing Liu, Haonan Yin +3
Open-vocabulary semantic segmentation (OVSS) in remote sensing images aims to segment categories beyond a fixed label space. Recent SAM 3-based methods provide a promising training…
Research on the Flat Field Measurement Method of Coronagraph
Yulong Feng, Xuefei Zhang, Hongfei Liang +4
The solar corona has an extremely low density, and its brightness is only about one millionth of that of the photosphere. High-dynamic-range imaging of its faint structure is there…
Low-regularity well-posedness for a mixed-sign quadratic Dirac equation on -star metric graphs
Huichao Xing, Zhipeng Yang
We study the Cauchy problem for a mixed-sign quadratic Dirac equation on a noncompact -star metric graph , \[ \mathrm{i}\partial_t ψ= Dψ- \mathcal N(ψ), \qquad ψ(0)=ψ_0, \] w…
