Abstract

fetched live from OpenAlex

This case reports a rare proximal left middle cerebral artery occlusion caused by cardiac papillary fibroelastoma (CPF), successfully treated with endovascular thrombectomy (EVT) followed by surgical resection of the cardiac tumour. Histological analysis of the EVT-retrieved specimen matched the mass identified on transoesophageal echocardiogram, confirming the diagnosis of CPF-associated embolic stroke. Early identification of CPF through histopathology likely expedited definitive treatment for this patient, who eventually made a full functional recovery.

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.
