Abstract

fetched live from OpenAlex

Genomic inbreeding coefficients (Fi) were estimated for 1515 Angus (AN), 1387 Charolais (CH), 549 Simmental (SM), and 430 Hereford (HE). Fi in this sample of AN and CH remained relatively stable at around 12.48% and 11.95%, respectively, between 2001 and 2013. AN and CH from the research centres had slightly lower Fi compared to those from their respective breed associations. The SM animals born between 2001-2013 had higher Fi (15.32%) than AN and CH year mates. The HE animals had the highest Fi at all times, averaged at 28.91%. Inbreeding depression for average daily gain (ADG) was also investigated in a multibreed and crossbred population of beef cattle. No statistically significant dependence between ADG and Fi was found.

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.

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.
