Preliminary Radiological Assessment of Age‐related Change in the Trabecular Structure of the Human<i>Os Pubis</i>*
Bibliographic record
Abstract
This preliminary study examines correlations between age-at-death and changes in the trabecular architecture of the human os pubis, utilizing continuous, quantitative data from plain film radiography, computed tomography (CT), and micro-CT scans of 65 male innominates. Radiography provides nondestructive options for assessment, digital preservation, and presentation of human skeletal remains; important for forensic and culturally sensitive archaeological materials, which must remain unmodified for opposing experts, future researchers, or repatriation and reburial. Radiographic techniques permit analysis of remains that cannot be disarticulated (e.g., religious proscription, mummies), and trabecular measures provide data where traditional surface indicators are obscured or damaged. Potentially, robust predictive models derived herein achieve R-values of 0.522, 0.447, and 0.731, respectively. Further testing of these methods may validate these techniques as further lines of evidence in age estimation, with the potential to improve on the accuracy of traditional qualitative techniques by providing quantitative, continuous variables in predicting skeletal age-at-death.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
