Abstract
I nuit infants in Qikiqtaaluk (Baffin) Region, Nunavut, Canada, have the highest reported rate of hospital admissions because of severe respiratory syncytial virus infection in the world, with annualized rates of up to 306 per 1000 infants. 1 High rates of hospital admission because of lower respiratory tract infections have also been reported among Native infants in Alaska 2 and Inuit infants in Greenland. Invasive Streptococcus pneumoniae infection, including pneumonia, is also relatively frequent. Respiratory syncytial virus infection is also unusually severe in this population: 12% of infants admitted to the Baffin Regional Hospital in Iqaluit (Qikiqtaaluk Region's regional hospital) required intubation and mechanical ventilation, necessitating costly and difficult air transport to tertiary care hospitals in southern Canada. 1 Inuit and Alaska Native infants also have disproportionately high rates of permanent chronic lung disease after a lower respiratory tract infection. 5 7] Their immune function appears to be normal, 6,9 and cystic fibrosis and primary ciliary dyskinesia are rare. Overcrowding and exposure to environmental tobacco smoke are believed to play important roles. entilation is the process by which fresh air is introduced and stale air removed from an occupied space. 11 Adequacy of ventilation can be evaluated directly or indirectly: directly, by measuring air change rates and occupancy and then calculating ventilation per person; indirectly, or by monitoring the indoor concentration of carbon dioxide (CO 2 ), which is a function of the number of occupants (the primary source of indoor CO 2 ) and the amount of airflow available to clear CO 2 from the building. 12 In the winter of 2003, we completed a pilot study evaluating indoor air quality in the homes of 20 Inuit infants in Cape Dorset, Nunavut. These homes were single-storey dwellings, raised above ground, and had no basements because of permafrost. 13 They were small relative to houses in southern Canada. Many of the houses were found to have inadequate ventilation, determined either directly or by evaluating indoor CO 2 . Exposure to environmental tobacco smoke was nearly

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
