Abstract

fetched live from OpenAlex

J amestown Canyon orthobunyavirus (JCV) is a neg- ative-sense RNA virus in the California serogroup. Its tripartite genome comprises small (nucleocapsid), medium (glycoprotein), and large (polymerase) segments. JCV is distributed throughout the United States and Canada and has been isolated from multiple mammals and mosquitoes (1,2). Most infections occur in adults, during the summer, and are asymptomatic, but manifestations can include fever and acute meningoencephalitis (2). Cerebrospinal fluid (CSF) typically shows a lymphocytic pleocytosis with elevated protein and normal glucose. Diagnosis is made by detection of JCV IgM in serum or CSF and confirmed by plaque-reduction neutralization testing to rule out cross-reactivity with other California serogroup viruses (3). Detection of viral RNA in human CSF has rarely been described, with viremia presumed to be of short duration, so reverse transcription PCR (RT-PCR) is not routinely used for diagnosis No specific treatments are available, although intravenous ribavirin has been reported to improve seizures (6). Because of the limited number of cases described, the full range of findings associated with JCV infection is unknown. No fatal cases were reported to the Centers for Disease Control and Prevention (CDC) before 2017, and no autopsy reports have been published (7).

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.
