Persistent Right Aortic Arch and Cribiform Plate Aplasia in a Northern Elephant Seal (Mirounga angustirostris)
Bibliographic record
Abstract
A female weanling northern elephant seal (Mirounga angustirostris) presented to The Marine Mammal Center in Sausalito, California, USA, in poor body condition. An esophageal obstruction was diagnosed by contrast radiography and esophagoscopy, but despite extensive diagnostics and supportive care, the seal died 6 days later. On postmortem examination, the right aortic arch was persistent, forming a vascular ring anomaly with a patent ductus arteriosus that compressed the distal esophagus. Aplasia of the right cribiform plate and hypoplasia of the right olfactory nerve was also identified. A review of necropsy reports from January 1988 to December 2003 revealed 16 severe congenital anomalies in 454 juvenile northern elephant seals that stranded in northern California.
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
