Abstract

fetched live from OpenAlex

Subalpine fir (Abies lasiocarpa (Hook.) Nutt.) is the fir species in the spruce-pine-fir (SPF) group harvested in British Columbia and Western Alberta. Due to preferential logging of lodgepole pine, the availability of subalpine fir is projected to increase significantly, in some regions to as high as 30 percent of the SPF mix. Examination of the properties of subalpine fir suggested opportunities for new higher margin products in applications where durability and dimensional stability are important such as decking. An experiment was designed to compare the dimensional stability of flat decking to ribbed decking using three copper-based preservatives: alkaline copper quat (ACQ-D), copper azole (CA), and chromated copper arsenate (CCA). Preservative treated and non-treated decks were installed at Forintek's western test site. After 17 months of exposure, the preservative-treated ribbed decks looked significantly better than the preservative-treated flat decking in terms of size of checks and visibility of checks.

Full frame distilled prediction

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.
