Abstract

fetched live from OpenAlex

Joint orientations were measured in the mountains of Western Albertaand British Columbia. These were then evaluated statistically accordingto the standard method of Kohlbeck and Scheidegger. If the bisectricesof the preferred joint orientations are interpreted as principal directionsof the neotectonic stress field, the maximum compression in the latteris found to be from NE-SW (in the South) to NNE-SSW (in the North).This agrees well with data regarding the neotectonic intraplate stressesobserved from oil-well break-out data.

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.
