Abstract
In this paper, the effect of different pulse and system parameters on the killing efficiency of PEF treatment was investigated. Escherichia Coli bacteria inoculated in apple juice was treated. The results showed that an electric field higher than 4 kV/mm is required to enhance the killing efficiency using PEF that has sufficient log reductions in the microbial numbers. The temperature rise during pulse application was found to be around 20degC, and it is observed that this rise in medium temperature has synergistic effect and has resulted in high inactivation. As the temperature rise can be limited to a value below the pasteurization temperature, the synergistic effect can be highly beneficial. While high killing rate was achieved for inoculated bacteria (3-4 log reduction), less than 2 log reduction was achieved for naturally growing bacteria in apple juice under the test conditions used.

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
