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…

Stratification and rectifiability of harmonic map flows via tangent measures

Haotong Fu, Wei Wang, Ke Wu +1

In this paper, we investigate the stratification theory for ``suitable solutions" of harmonic map flows based on the spatial symmetry of tangent measures. Building on the quantitat…

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…

Existence of positive and sign-changing solutions for a Choquard equation involving mixed local and nonlocal operators

Shaoxiong Chen, Hichem Hajaiej, Min Yang +1

We study the Choquard equation involving mixed local and nonlocal operators \[ -Δu + (-Δ)^{s}u + V(x)u = \left(\frac{1}{|x|^μ} * F(u)\right) f(u) \quad \text{in } \mathbb{R}^{2}…

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,…
