Abstract
The two-plasmid rescue method of constructing Ad vectors, which relies on either homologous or Cre-mediated recombination between two plasmids cotransfected into 293 or 293Cre4 cells, respectively, offers advantages over other approaches because of its simplicity. We have improved the efficiency of vector construction by both homologous and Cre-mediated recombination by replacing the single ITR in the shuttle plasmid with a head-to-head ITR junction. We have also expanded the versatility of this method by incorporating a Cre expression cassette into the plasmids to permit high-efficiency Cre-mediated vector rescue using 293 cells, abrogating the need for Cre-expressing cell lines. This new system retains the simplicity of the original but results in an approximately 100-fold increase in the number of recombinant viruses produced, all of which contain the foreign DNA insert, and allows high-efficiency Cre-mediated vector isolation using any E1-complementing cell line.

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
