Admissible Reconstruction of Reaction-Channel Levels on Fixed Subgroup Support for Cross-Section-Space Probability Table Constructions
Beichen Zheng, Lili Wen
In cross-section-space probability table constructions, reaction-channel levels are reconstructed on fixed total-subgroup nodes and probabilities. Although the standard full-matchi…

A finite-precision Lanczos-Golub-Welsch route to probability-table construction in resonance self-shielding
Beichen Zheng
This work reformulates Chiba's affine-order prescription as a polynomial-moment problem for a transformed positive measure, and develops an alternative finite-precision constructio…

Robust Subgroup Method Using DE Algorithm for Resonance Self-Shielding Calculation
Beichen Zheng, Ying Chen, Lili Wen +1
This paper presents an enhanced version of the subgroup method for resonance self-shielding treatment, termed the robust subgroup method, which integrates Robust Estimation (RE) wi…
