Analytic smoothing effect of Cauchy problem for a class of Kolmogorov-Fokker-Planck equations
Xiao-Dong Cao, Chao-Jiang Xu, Yan Xu
We study the Cauchy problem of the Kolmogorov-Fokker-Planck equations and show that the solution enjoys an analytic smoothing effect with L2 initial datum for positive time.
Nucleus-aware Self-supervised Pretraining Using Unpaired Image-to-image Translation for Histopathology Images
Zhiyun Song, Penghui Du, Junpeng Yan +5
Self-supervised pretraining attempts to enhance model performance by obtaining effective features from unlabeled data, and has demonstrated its effectiveness in the field of histop…
Extreme Red-wing Enhancements of UV Lines During the 2022 March 30 X1.3 Solar Flare
Yan Xu, Graham S. Kerr, Vanessa Polito +3
Here we present the study of a compact emission source during an X1.3 flare on 2022-March-30. Within a ~s period (17:34:48 UT to 17:35:29 UT), IRIS observations show spectr…
NICE: CVPR 2023 Challenge on Zero-shot Image Captioning
Taehoon Kim, Pyunghwan Ahn, Sangyun Kim +39
In this report, we introduce NICE (New frontiers for zero-shot Image Captioning Evaluation) project and share the results and outcomes of 2023 challenge. This project is designed t…
Analytic Gelfand-Shilov smoothing effect of fractional Kramers-Fokker-Planck equation
Chao-Jiang Xu, Yan Xu
We study the Cauchy problem of the fractional Kramers-Fokker- Planck equation and show that the solution to the Cauchy problem enjoys an analytic Gelfand-Shilov regularizing effect…
Port-Hamiltonian formulations of the incompressible Euler equations with a free surface
Xiaoyu Cheng, J. J. W. Van der Vegt, Yan Xu +1
In this paper, we present port-Hamiltonian formulations of the incompressible Euler equations with a free surface governed by surface tension and gravity forces, modelling e.g. cap…
