PstpNet: Dual-Branch Physics-Guided U-Net With Multiscale Spatiotemporal Disentanglement for Precipitation Nowcasting

Precipitation nowcasting remains challenging because precipitation systems exhibit strong nonlinear evolution, rapid development, and complex long-range spatiotemporal dependencies. Existing deep learning methods are still limited in characterizing precipitation dynamics and improving model interpretability. To address...

Event-Guided Spatiotemporal Transformer with Conditional Diffusion Refinement for High-Intensity Precipitation Nowcasting

Accurate nowcasting of high-intensity precipitation is critical for urban flood control and short-term hydrological risk management. However, the high stochasticity of convective systems poses a significant challenge for traditional deep learning models in generating accurate predictions. Existing regression-based mode...

VOLE-CPSI Meets Paillier Aggregation: Practical Private Intersection Cardinality with Linear-Scale Performance

Private set intersection (PSI) and its circuit variant (Circuit-PSI, CPSI) are core tools for privacy-preserving analytics. Unlike plain PSI that directly reveals intersecting elements, CPSI outputs secret shares of intersection indicators (and associated-value shares), which can be reused in subsequent MPC tasks witho...
