ScatterPrism: convergence for generative simulation and inverse problems in particle and nuclear physics
Zeyu Xia, Tyler Kim, Trevor Reed +3
The paper introduces ScatterPrism, a generative surrogate that exposes shortcomings of the standard Conditional Flow Matching loss in particle‑physics simulations and proposes mult…
Accurate identification and measurement of the precipitate area by two-stage deep neural networks in novel chromium-based alloys
Zeyu Xia, Kan Ma, Sibo Cheng +7
The performance of advanced materials for extreme environments is underpinned by their microstructure, including the size and distribution of reinforcing phases. Chromium-based sup…
PyTorchFire: A GPU-Accelerated Wildfire Simulator with Differentiable Cellular Automata
Zeyu Xia, Sibo Cheng
Accurate and rapid prediction of wildfire trends is crucial for effective management and mitigation. However, the stochastic nature of fire propagation poses significant challenges…
FireDataForge: A Unified Framework for Multi-Source Wildfire Data Retrieval and Integration
Zeyu Xia, Lexie Chen, Ye Liu +1
Wildfire research, modeling, and education require geospatial data from multiple sources that vary in formats, coordinate systems, spatial resolutions, and temporal cadences. This…
Cosmo3DFlow: Wavelet Flow Matching for Spatial-to-Spectral Compression in Reconstructing the Early Universe
Md. Khairul Islam, Zeyu Xia, Ryan Goudjil +3
Reconstructing the early universe from the evolved present-day universe is a challenging and computationally demanding problem in modern astrophysics. We devise a novel generative…
