Abstract
Abstract A finite‐dimensional, state‐space model of the discrete distribution function bypasses discretization of the continuous population balance, and facilitates simple modeling and fast numerical integration. An analytical expression describes the steady‐state, average particle diameter as a function of parameters such as nucleation, agglomeration, breakage, seed rate, and average seed particle diameter. The discrete population balance model is used to evaluate the analytical expression sensitivity to growth and decay phenomena such as nucleation, agglomeration, and breakage. The analytical expression is validated against data obtained from an industrial‐scale, fluidized bed, pilot reactor designed to produce solar‐grade silicon. The results indicate how the analytical expression describes a CVD‐type growth process, and also how the growth process may deviate due to the operating conditions.

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
