Abstract
The effect of PFI separate refining and co-refining on paper properties was investigated for aspen bleached CTMP (BCTMP) and eucalyptus kraft pulp (EKP). The results showed that for a given freeness, separate BCTMP/EKP PFI refining required more energy than BCTMP/EKP co-refining; compared with BCTMP/EKP separate refining, BCTMP/EKP co-refining produced handsheets with improved surface smoothness and physical strength, while there was no significant difference in opacity and light scattering between these two refining processes. The results indicate that, in paper mill practice, it is possible to choose an appropriate addition level of BCTMP in KP and an appropriate refining process to maintain acceptable paper bulk and paper smoothness.

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
