Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

<abstract> <b><sc>Abstract.</sc></b> For effective use of manure as fertilizer, manure properties must be known. However, there is a lack of information on the quantity and nutrient contents of as-removed feedlot manure. Few studies have measured the amount of manure produced by feedlot cattle, and consequently nutrient loss between as-excreted and as-removed feedlot manure is poorly understood. In Saskatchewan, a calf fed from 386 to 590 kg (850 to 1300 lbs) in 150 days can have manure production of 13.6 kg d<sup>-1</sup>, and the manure can have nitrogen content of 7.5 kg t<sup>-1</sup> and phosphorus content of 2.0 kg t<sup>-1</sup>. Nitrogen loss between as-excreted and as-removed manure can range between 50% and 60%, and phosphorus loss can range between 10% and 30%. The model presented in this article allows feedlot operators, nutrient management specialists, and regulatory agencies to predict the properties of manure, as long as the diet, bedding usage, and moisture content are known.

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.
