Abstract

fetched live from OpenAlex

A "lung point" is the interface between present and absent lung sliding artifacts identified by point of care ultrasound (POCUS). This finding has long been considered highly specific for pneumothorax, with certain studies citing a specificity as high as 100%. More recently, multiple cases that mimic the lung point have been reported. Here, we present a patient case with bilateral lung points in the absence of pneumothorax. We reviewed lung point mimics and explored the conditions that caused this finding without pneumothorax.

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.
