Abstract

fetched live from OpenAlex

The mitochondrial genome of Ophiostoma himal-ulmi, a species endemic to the Western Himalayas and one of the fungi that cause Dutch elm disease, has been sequenced and characterized. The mitochondrial genome was compared with other available genomes for members of the Ophiostomatales, including other agents of Dutch elm disease (Ophiostoma ulmi, Ophiostoma novo-ulmi subspecies novo-ulmi, and Ophiostoma novo-ulmi subspecies americana), and it was observed that gene synteny is highly conserved, and variability among members of the fungi that cause Dutch-elm disease is primarily due to the number of intron insertions. Among the fungi that cause Dutch elm disease that we examined, O. himal-ulmi has the largest mitochondrial genomes (ranging from 94 934 to 111 712 bp), owing to the expansion of the number of introns.

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.
