Data-Driven Reconstruction of Spatially Resolved Electron and Ion Energy Distributions from Macroscopic Plasma Quantities with Deep Neural Networks

Aug 17, 2026

This study addresses the challenge of measuring kinetic energy distributions in low-temperature plasmas by proposing a deep learning-based nonlinear inverse mapping method. Utilizing 2D-3V PIC-MCC data, U-Net, FNO, and MeshGraphNet models were trained to reconstruct microscopic energy distributions from macroscopic observables. This work validates for the first time that macroscopic quantities contain sufficient information to infer kinetic properties, establishing a new paradigm for surrogate kinetic modeling. Results demonstrate that the reconstructed distributions accurately reproduce bulk and sheath characteristics, with FNO exhibiting superior performance and key physical parameters aligning closely with reference data. These findings offer a novel pathway for next-generation plasma diagnostics.

ChainLearn: A Blockchain-Based Capacity-Aware Framework for Federated Ensemble Learning

May 23, 2026

This work addresses the challenge of heterogeneous computational resources across hospitals in medical imaging federated learning, which often renders standard algorithms ineffective. The authors propose a heterogeneous federated ensemble learning framework that does not require a unified model architecture. By evaluating each participant’s computational throughput, the system dynamically assigns tailored models—such as MobileNetV3-Small, EfficientNet-B0, or ResNet-50—and performs weighted ensemble inference off-chain. A blockchain-based mechanism, implemented via Solidity smart contracts, manages participant registration, performance metrics, and ensemble weights, while only uploading hashes and scalar values to preserve privacy and efficiency. Experiments on PneumoniaMNIST and DermaMNIST demonstrate that the method achieves calibration error no worse than uniform-weight ensembles and accuracy comparable to FedAvg, with a per-round communication overhead of merely 224 bytes—over 910,000 times lower than FedAvg.
