Abstract

fetched live from OpenAlex

During a diaper change, a previously healthy six-week-old boy was noted to have new left leg swelling involving the foot, ankle, and calf. Over the next two days, the swelling remained unchanged. There was no redness, warmth, or bruising and no history of trauma. He was otherwise well without changes to his feeding or the functioning of his leg. He was brought to the hospital because of the persistently swollen limb. On examination in the Emergency Department, he was afebrile, vitally stable, and non-dysmorphic. Weight was 6.0 kg (97th percentile). His left leg measured 17 cm at the widest point in the calf, and the right measured 15 cm. There was no pitting edema, erythema, tenderness, warmth, bruising, or nodules. The remainder of the general physical exam was normal (Figure 1). ... He was born term via vaginal delivery without complications and required one day of phototherapy. Family history was negative for malignancy, clotting or bleeding disorders.

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.
