Abstract

fetched live from OpenAlex

Romer and Price (1940) proposed a standard of unit measurement that they used in studying a group of fossil reptiles, the Pelycosauria. The basis for the system is the orthometric linear unit (r13, where r is half the transverse width of a dorsal vertebral centrum). In a re-examination of the pelycosaurian genus Haptodus, it became apparent that it is necessary to restrict the use of the orthometric linear unit to linear dimensions of the skeleton that do not show interspecific allometry. Under this condition, differences in the unit measurements have quantitative, biological significance. Furthermore this system cannot be used directly with immature animals. Otherwise, unit measurement, based on the orthometric linear unit, would be a useful system within any group of animals where the backbone is encountering the same types of gravitational and propulsive forces.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
