Abstract

fetched live from OpenAlex

Short rotation woody crops are grown to be used as feedstock for energy and industrial purposes in many countries of Europe, and in the USA and Canada. Wood biomass is acquired from forests, the wood industry, and as a by-product of trimming trees and bushes. In future, considerable amounts of wood biomass should be supplied by dedicated energy crops (willow, poplar, black locust). The aim of this study was to determine the morphological features, yield and energy value of the yield of three species of plants grown at a site with poor soil quality and low usability for edible crops. The study has shown that the species of willow and poplar can be grown on poor quality agricultural land because they provide high yield, high energy, and high coal equivalent. However, the biomass of black locust may fail to provide sufficient yield to justify setting up a plantation using this species.

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.
