Abstract

fetched live from OpenAlex

Cores of Cedrus deodara D. Don from two different sites of western Himalaya were subjected to densitometric analysis to obtain data for earlywood, latewood, minimum, maximum, and mean densities and total ring width. Most of these variables show moderately high values of common variance and signal to noise ratio except latewood and maximum densities. These analyses suggest density parameters of this species may be useful in dendro climatic studies. Response function analyses indicate significant relationships between pre-monsoon (March-April-May) summer climate and earlywood density parameters, as well as total ring width. Based on the relationships derived from response function analyses, the potential of tree-ring chronologies from this species to provide reconstructions of the pre-monsoon climate in western Himalayan region has been established.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
