Abstract
Summary Form only given, as follows. The problem of describing the evolution of the particle size distribution is considered. The authors use a statistical model, and they describe the evolution of the moments of the distribution instead of the distribution itself. Applying a macroscopic population balance to the moments equations leads to the formulation of conservation equations in terms of the moments of the distribution. Using psi -z coordinates reduces the problem to a one-dimensional problem in the direction of a stream line. This procedure is applicable when the ultrafine particles do not cross the stream lines, so that their lateral mobility is small with respect to the flow. The calculated temperature and average ultra-fine-particle diameter fields are presented for a simplified case, where a hot flow of argon with 10% iron vapor at 4000 K mixes with a pure argon flow at 2000 K.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
