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

When geriatrician Thomas Perls treated his first centenarians in 1992, he expected to find them debilitated by illness and dementia. But he instead discovered that some extremely old individuals can escape Alzheimer's disease and other age-related disorders. In 1994 at Harvard Medical School, he started the New England Centenarian Study (NECS), a survey that has grown into an international investigation with data on 1000 centenarians from the United States, Canada, Germany, Japan, and Australia. Now based at the Boston University School of Medicine, the study has toppled several misconceptions about extremely old age and suggests a genetic basis to exceptional longevity. The work led to the founding of a biotech company called Centagenetix, which subsequently merged with Elixir Pharmaceuticals.

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.
