Reproducible Dataset for "A General Intensity-Structure Separation Principle: Persistent Response-Mode Locking under Spatiotemporal Forcing"

This reproducible dataset accompanies the following study: Doijiri, O. (2026). A General Intensity-Structure Separation Principle: Persistent Response-Mode Locking under Spatiotemporal Forcing. Zenodo. DOI: 10.5281/zenodo.21987360. This package provides the data and computational materials required to reproduce the principal numerical findings reported in the study. It includes the original sandstone-impact audio recordings, numerical source code, reproduction scripts, reference numerical outputs, and figures. The study investigates a General Intensity-Structure Separation Principle, in which forcing amplitude primarily controls response intensity, whereas normalized spatiotemporal forcing structure and fluid conditions primarily determine the selected response structure. Across acoustic and non-acoustic forcing, peak enstrophy remained approximately quadratic with forcing amplitude, while effective vortex scale and dominant wavenumber remained comparatively insensitive to amplitude. This persistent structural behavior is termed Persistent Response-Mode Locking. The reproducibility package includes the dedicated transition analysis spanning amplitudes from 0.1 to 204.8, corresponding to a 2,048-fold amplitude range, across 16 forcing/mapping/viscosity conditions, together with a separate smaller-time-step extreme-amplitude sensitivity analysis extending to 1638.4. The purpose of this dataset is to enable independent reproduction, verification, and falsification of the reported numerical findings. The proposed intensity-structure separation and persistent response-mode locking should be regarded as a numerical law candidate within the tested model class, rather than an established universal physical law of turbulence.
