Abstract

fetched live from OpenAlex

Fraxinus pennsylvanica is distributed in the central and eastern USA and Canada. It is assessed as Critically Endangered (CR). In this study, the complete chloroplast (cp) genome sequence of F. pennsylvanica was determined using next-generation sequencing. The entire cp genome was determined to be 155,543 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 86,389 and 17,806 bp, respectively, which were separated by a pair of 25,674 bp inverted repeat (IR) regions. The genome contained 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall AT content of the genome is 37.8%. A phylogenetic tree reconstructed by 10 chloroplast genomes reveals that F. pennsylvanica is most related with F. chiisanensis.

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.
