Abstract

fetched live from OpenAlex

Coronavirus disease 2019 (COVID–19), reported pandemic in March 2020, is the current health problem with no definite prevention or treatment. As a newly emerging disease, new cases are reported each day to add to the physician’s knowledge about the best clinical approach. One of the controversies in this regard is the gold standard diagnostic method. Evidence suggests that polymerase chain reaction (RT–PCR) for Coronavirus nucleic acid has a low sensitivity and computed tomography (CT) has been suggested for more accurate diagnosis. Yet, CT has the disadvantage of radiation and is not safe in all patients. Here, we present a case series of 23 patients who underwent both RT–PCR and CT and report the outcome.

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.
