Abstract
A spectral inversion method adopting new functional model of damping factor with its lower limit is proposed for identifying more sophisticated attenuation characteristics of rock sites. The proposed model is applied to borehole array data recorded at hard rock sites. The identified lower limits of damping factor agree well with experimental material damping factors derived from laboratory test of rock samples. Therefore it can be interpreted that the lower limit of proposed model may be corresponding to actual material damping factor. Moreover, we indicate that frequency dependent characteristics of the damping factor at rock sites could be interpreted as a theoretical damping due to scattering of inhomegeneous rock.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
