Abstract

fetched live from OpenAlex

Unilateral absence of the pulmonary artery is a congenital disorder resulting from malformation of the sixth aortic arch during embryogenesis. This case report presents a unique instance of unilateral absence of the pulmonary artery, incidentally discovered in an individual with multiple myeloma. Despite a history of recurrent childhood pulmonary infections, the patient remained asymptomatic until presenting with symptoms of myeloma. Imaging revealed a right-sided aortic arch, absent left pulmonary artery, and left lung atrophy with atelectasis. Among various collateral arteries, a notable finding in this case is the left gastric artery supplying the left lower lobe.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
