Abstract
Abstract African swine fever (ASF) continues to cause outbreaks throughout regions of Africa, Europe and Asia. The disease can cause severe morbidity and mortality resulting in serious economic losses. Since there is no vaccine available to control ASF, early detection is critical to contain and control the disease. The aim of this study was to develop a novel real‐time PCR assay based on highly conserved ASFV gene E183L (p54). The limit of detection of the assay, VNUA‐p54 real‐time PCR, was 2.63 copies/reaction and 2 Log 10 HAD 50 /ml. The VNUA‐p54 real‐time PCR was able to detect fifteen different ASFV reference strains representing p72 genotypes I, II and V. The assay was specific and did not amplify other swine viruses including CSFV, FMDV, PRRSV and PEDV. The diagnostic sensitivity of the real‐time PCR assay was evaluated using 200 field clinical specimens collected from swine farms located in different provinces in Vietnam. The VNUA‐p54 real‐time PCR assay is an additional tool for ASF diagnostics and can be used in combination with other p72 based ASFV real‐time PCR assays as a rapid confirmatory assay.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
