Abstract

fetched live from OpenAlex

A 31-year-old male presented with transient numbness of the right hand, progressing to involve the forearm. The symptoms lasted for around 30 minutes without any associated weakness or positive motor phenomena. An evaluation in the emergency room revealed no focal deficits.Acomputer tomogram (CT) scan performed in the emergency room suggested a few abnormal vascular structures in relation to the left hemisphere, with no evidence of hemorrhage. The patient was referred for magnetic resonance imaging (MRI) and conventional angiography. The MRI showed a diffuse network of densely enhancing vascular spaces involving the left middle cerebral artery (MCA) and anterior cerebral artery (ACA) territories without a clear nidus or abnormal parenchymal signal change (Figure 1). There was no involvement of the basal ganglia or thalami. Given the size and extent of the abnormality, there was a relative paucity of draining vessels, which were only moderately enlarged.

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.
