Abstract

fetched live from OpenAlex

Exposure to PM 2.5 pollution in Hanoi at the WHO threshold of 15 μg/m 3 led to significantly more premature deaths than under Vietnam's 50 μg/m 3 standard, especially from respiratory diseases. In 2023, economic losses reached 6.3 % of the city's GRDP, highlighting serious health and financial impacts. The study revealed seasonal, gender, and district-level differences, with mortality peaking in Quarter 1 and a slight female predominance. These findings underscore the urgent need for stricter air quality standards and effective pollution control to protect public health and reduce economic burden.

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.
