Abstract

fetched live from OpenAlex

The purpose of this study was to determine if tonewood qualities of Interior spruce, a common name used to describe the grouping of Engelmann spruce (Picea engelannii [Parry] Engelm.) and white spruce (P. glauca [Moench]), were different between two stands. The two stands selected were near McBride, British Columbia, Canada (latitude 53.3053°; longitude -120.206°) and were approximately 20 km apart, with an elevation difference of approximately 700 m. There were 20 and 11 samples taken from the lower elevation and the higher elevation stands, respectively. Billets from the mature sapwood zone of the trees were equilibrated at about 6 percent moisture content. A sound wave timer was used to determine the velocity of the sound wave in the longitudinal direction and the ovendry density was determined. The acoustic constant (AC) value was determined and the results showed no statistical difference in the AC values between the two stands. However, there was a significant difference in the density between the two stands. The density was greater for the higher elevation stand, suggesting Engelmann spruce as the dominate species, and suggesting that white spruce, having a lower density, was at the lower elevation site. However, despite the density difference, the AC values were statistically the same.

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.
