Canada: Capitalizing on a 50-Year Legacy
Bibliographic record
Abstract
Canada has an exceptional history of advancing the eld of stem cell research. In fact, a strong case can be made that it all started here in 1961 when Drs. James Till and Ernest McCulloch, a physicist and a hematologist at the Princess Margaret Hospital in Toronto, were the rst in the world to identify and characterize stem cells. Over the next few years, they published a series of seminal papers (Becker et al. 1963) that dened the lexicon of stem cell research still in use 50 years later. It is an achievement for which they were recognized with the Lasker Prize in 2005.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
