AI Surrogate Modeling for Real-Time Tokamak Equilibrium Prediction: Benchmarking Neural Architectures and Validation on EXL-50U

Fast and reliable plasma equilibrium prediction is essential for real-time tokamak operation and control, but conventional Grad-Shafranov (GS) solvers are often too costly for real-time deployment. We develop an AI surrogate framework and benchmark five architectures (MLP, CNN, FNO, Transformer, and KAN) on a numerical...

Mecury: Integrating Account Allocation and Scheduling for Enhancing Blockchain Sharding Performance

Existing sharded blockchain systems suffer from excessive cross-shard communication overhead and workload imbalance. Although state-of-the-art account allocation schemes partially alleviate these problems, they still fail to simultaneously achieve effective cross-shard transaction reduction and balanced workload distri...
