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 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

The experiment was conducted in a fumigated soil which had been cropped with cereals in the previous year. The five treatments were: introduced arbuscular mycorrhizal (AM) fungi-inoculum dispersed; introduced AM fungi-inoculum placed; indigenous AM fungi-inoculum dispersed; indigenous AM fungi-inoculum placed; and uninoculated. Phaseolus vulgaris cv. Canadian Wonder was sown in furrows of standard spacing. Plants were harvested on three occasions. Inoculation with both introduced and indigenous AM fungi improved the growth and yield of beans. These fungi increased leaf area and differences were mantained until the final harvest. The shoot dry weight was also consistently higher in inoculated than in the uninoculated plants. Mycorrhizal infection was greatest when inoculum was placed below seeds at planting than dispersed, although the differences at individual harvests were not significant.

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.
