Abstract
To provide a new ideas for the study of the mechanism of porcine parvovirus replication,the experiment used PPV-BQ strain of porcine parvovirus vaccinated subculture ST cells,extracted the total RNA when the virus replicated in the process of ST cells,and then reversed transcription into cDNA.mRNA fragments of NS2 gene about 486 bp and Pre-mRNA fragment of the NS2 gene about 1 959 bp were amplified by RT-PCR.Each of the gene was cloned into the vector pMD18-T and sequenced.The results showed that mRNA fragments in NS2 gene of PPV-BQ strain shared 97.4%～99.4% and 94.4%～98.8% homology with published in GenBank at nucleotide sequence and amino acid level,respectively.According to phylogenetic analysis,PPV-BQ strain has a close genetic relationship with SR-1 strain isolated in Si-Chuan,Kresse strain isolated in Canada and NADL-2 strain isolated in USA.Acquired NS2 gene mRNA during replication lay the foundation for the research of gene expression in NS2 protein and its function.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
