Abstract

fetched live from OpenAlex

Earlywood (E) and latewood (L) are arbitrary concepts, by consequence, the E/L demarcation method is as well. The threshold method has been widely used in wood anatomy as well as wood density. Because of the presence of the intra-annual variation in tree-ring structure, however, the conventional threshold method needs adjustment in an objective and effective way. We suggest the analysis of the error zone method for this adjustment. The method was tested with 500 radial cell files of mature balsam fir, and showed its potential as an objective, robust and easily applicable adjustment tool. multiple intra-ring demarcation / intra-ring variation / wall-lumen ratio / Mork's definition / wood anatomy Rsum -Une mthode pour la dmarcation intra-cerne multiple de conifre. Le bois initial et le bois final sont des concepts arbitraires, de mme que leur dmarcation. La mthode de seuil est applique gnralement dans le domaine de l'anatomie et de la densit du bois. Mais, la mthode conventionnelle du seuil ncessite des ajustements parce qu'il y a des variations dans la structure du cerne. Nous suggrons la mthode de l'analyse de la zone d'erreur pour effectuer cet ajustement. La mthode suggre a t vrifie avec 500 files radiales de cellules de sapin baumier matures, et elle a dmontr son potentiel comme un moyen objectif, robuste et facile appliquer. dmarcation intra-cerne multiple / variation intra-cerne / ratio parois-lumen / dfinition de Mork / anatomie du bois

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.
