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

From November 1992 to March 1993 fourteen patients received the Toronto SPV stentless porcine xenograft as aortic valve replacement. Median age was 56 years (range 32-70 years). 7 patients were male and 7 female. Implanted valve sizes ranged from 23 mm to 29 mm, the majority of patients received valves with 27 and 29 mm tissue diameter. A learning process was evident by aortic crossclamp time decreasing with experience. No valve-related mortality or morbidity occurred. Postoperatively echocardiography showed near normal valve performance in most patients. The longevity of the valve, however, still has to be established. Meanwhile we continue the implant of stentless bioprostheses as aortic valve substitutes in selected patients.

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.
