Abstract
Substituting BCTMP for chemical pulps,such as bleached hardwood kraft pulp in many paper grades is in rising demand for reducing cost and improving product performance.In this paper we investigated the effect of substituting aspen BCTMP for hardwood kraft pulp(varying from 10% to 30%)on product performance of light weight coated paper.The results showed that the tensile index increases and other strength properties are essentially unchanged as the substitution level increases.The surface roughness of the base paper increases slightly with the BCTMP substitution level,while coating coverage of the base paper is not affected significantly.The increased BCTMP substitution results in an increase in porosity of the base paper,but does not change the average pore diameter.Increasing BCTMP substitution level leads to a slight decrease in gloss and,an increase in surface roughness of the coated paper,however the latter can be compensated by a higher nip-load calendaring.

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
