Abstract
Asthmatic individuals typically experience exaggerated decrements in their ability to breathe after receiving standardized doses of smooth muscle agonist, a phenomenon known as airways hyperresponsiveness (AHR). Breathing difficulties are caused by excessive narrowing of the pulmonary airways, which is instigated by shortening of the airway smooth muscle (ASM). Exactly why many asthmatic individuals are hyperresponsive, however, remains controversial because of the many varied mechanisms that could possibly be involved. Nevertheless, much of the understanding of AHR comes down to a matter of considering the spatial configuration of the components that make up the airway, and the static and dynamic physical forces these components experience. In this review, we consider these mechanical factors, which are conveniently subdivided into three groups involving (i) the active forces construing to narrow the airways, (ii) the mechanical loads against which these forces must work, and (iii) the geometric transformation of a given degree of ASM shortening into airway narrowing. Each of these groups of factors has potent potential to influence AHR. It is likely, however, that they operate together to produce the AHR characteristic of severe asthma.

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
