Abstract

fetched live from OpenAlex

The impact of feed processing and in vitro ruminal cultures on the persistence of recombinant and canola-specific endogenous DNA was studied using various canola substrates (whole seed, cracked seed, meal and diet). For both, parental and genetically modified substrates, ribulose-1,5-bisphosphate carboxylase/oxygenase gene was amplifiable up to varying time points. Persistence of recombinant DNA, encoding 5-enolpyruvylshikimate-3-phosphate synthase (1,363 bp) was detected up to 8 h for meal and 4 h for mixed diet. Upon processing of canola, DNA large enough to contain intact plant genes remains. In an in vitro environment, plant DNA was rapidly degraded upon its release into rumen fluid.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
