Abstract

fetched live from OpenAlex

Seven cuticle chitin-binding proteins (Ld-CP1v1 to 7) were deduced from antenna cDNAs of adult Colorado potato beetles, Leptinotarsa decemlineata (Say), based on their consensus sequences. The mature proteins consisted of 87-188 residues. Ld-CP1v1 formed a distinct orthologous protein cluster (OP1) along with four proteins from other insect species in a neighbor-joining phylogenetic tree. These proteins also contained a proline glutamine-rich (PQ-rich) region and a highly conserved C-terminal motif (Phr). Their consensus region lacked the defined aromatic triad. Ld-CP2 to 6 clustered with those bearing RR-1 consensus and Ld-CP7 with RR-2 consensus. Ld-CP1v1 to 4 were expressed at the post-ecdysial period in all the developmental stages whereas Ld-CP5 to 7 were expressed mainly in adults.

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.
