Abstract

fetched live from OpenAlex

A two-round nested polymerase chain reaction assay detected Rous associated virus-1 (RAV-1), a prototype laboratory strain of avian leukosis virus of subgroup A (ALV-A). Surprisingly, the test failed to detect three field isolates of ALV-A but did detect virus in one commercial stock of chickens (stock F). The sequence analysis of a core of 290 nucleotides of the env gene gave evidence that the virus from stock F was closely related to avian myeloblastosis-associated virus type one (MAV-1). Other primers were used to amplify and sequence a 1491 nucleotide fragment of the env gene, and a 1245 nucleotide portion of this sequence used for a phylogenetic comparison. These analyses on 10 chickens gave evidence that six were infected with MAV-1-like virus and three with RAV-2 (subgroup B virus), and one chicken with a mixture of the two viruses. Tests with primers designed specifically for the MAV-1 sequence at a pre-determined target site and a second primer designed specifically for RAV-2 at the same site gave further evidence that the viruses isolated from stock F were closely related to one or other of these two viruses.

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.
