Abstract

fetched live from OpenAlex

Fundamental wood and fibre properties determine end product quality potential. They are affected by silvicultural practices. Initial stand stocking density has significant economic implications for both forest managers and industrial end users. An evaluation of the wood density and fibre properties of 38-year-old coastal western hemlock (Tsuga heterophylla (Raf.) Sarg.) planted at five different spacings was completed. We determined that the wood density was not affected by spacing. At the widest spacing, the outer wood fibre length was significantly shorter than at the four tighter spacings. Fibre coarseness and cell wall properties were similar at all spacings. This implies that wood chips prepared from a range of small-diameter thinnings material will not adversely affect kraft pulp fibre properties.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
