Abstract

fetched live from OpenAlex

Abstract In this report, two softwood kraft pulps, one originating from chips and the other from sawdust, and a hardwood kraft pulp originating from chips were fractionated individually with regard to fibre length using a Bauer-McNett apparatus. The fibre length, the coarseness, the 0.5% viscosity and the intrinsic viscosity were measured on all fractions and whole pulps. For every pulp, there was a unique positive relation between fibre length and viscosity, and also between fibre length and coarseness. Since fibre length has a direct impact on pulp strength, viscosity measurement can provide an indirect method to predict pulp strength. This relationship between the two datasets increases the value of viscosity as an analytical tool.

Teacher imitation

Not 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.
