Abstract

fetched live from OpenAlex

The complete mitochondrial genome of hybrid F2 from Acanthopagrus schlegelii (♀) × Pagrus major (♂) was obtained using high-throughput sequencing technology. The circular genome was 16,648 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. Overall, nucleotide composition was A: 28.02%, T: 27.88%, C: 27.93%, G: 16.17%. Nine genes were encoded on the light strand and the remaining 28 genes were encoded on the heavy strand. All protein initiation codons are ATG except for COI that begins with GTG. The phylogenetic analysis suggested that hybrid F2 of A. schlegelii (♀) × P. major (♂) was closest to A. schlegelii. The newly described mitochondrial genome may provide valuable data for the genetic and taxonomic research on artificial hybrid seabream.

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.
