Abstract

fetched live from OpenAlex

Previous studies of mantle plume motions have assumed that any movement occurred within an Earth of fixed size. A comparison of distances between pairs of hot spots and their traces for different ages generally indicates less separation further back in time. The apparent changes in great circle distances between plumes may be consistent with constant separations in terms of geocentric angles, with an increase in the Earth's radius of up to 12 per cent over the past 120 My. The evidence for an expansion over the past 50 My may be inconclusive, due to the errors in the data for plume locations.

Full frame distilled prediction

Teacher imitation

Not 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.
