Abstract
Abstract Experimental minimum burning pressures (MBP) of emulsions with solution phase containing ammonium nitrate/water, ammonium nitrate/sodium nitrate/water, and ammonium nitrate/sodium nitrate/sodium perchlorate/water are investigated. A correlation is proposed to relate the MBP’s with the combustion temperatures. The formulations containing sodium nitrate or sodium perchlorate have much lower MBP’s and can be accounted for by an activation energy of 150.7 kJ mol −1 obtained from literature for ingredients having catalyzing effects on the reaction of ammonium nitrate, e.g. sodium nitrate. The ammonium nitrate/water formulations have a higher activation energy of 173.4 kJ mol −1 deduced from an analysis of the data. The MBP vs. combustion temperature plot is linearized by a multiplication factor to the MBP that includes the activation energy of the corresponding system. This allows the MBP to be predicted from combustion temperatures determined from the formulations and the corresponding activation energy.

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
