Abstract

fetched live from OpenAlex

Based on four remote sensing images (MSS in 1978 and TM in 1990,2000 and 2006),the spatial-temporal changes of woodlands in the Shangluo section of the Qinling Mountains were analyzed with the support of ERDAS and GIS.Over the past 30 years,the total area of the woodlands increased from 12584.55 km2 to 14479.44 km2.The area of coniferous forests and shrubs both increased,while the area of coniferous-broad mixed forests and latifoliate forests decreased.The change of various woodlands in the low-elevation regions was more serious than that in high-elevation regions.The woodlands became fragmented and their internal structure has fundamentally altered,i.e.most of the latifoliate forests have been replaced by coniferous forests.The major driving forces for such changes are from regional socio-economic resources,farmers' incomes and the demands for arable land.

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.

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.
