Abstract
There is now increasing evidence that ionizing radiation generates complex DNA damage, i.e. two or more lesions--single-strand breaks or modified nucleosides--located within one to two helical turns on the same strand or on opposite strands. Double-strand breaks are the most readily recognizable clustered lesions, but they may constitute a relatively minor fraction of the total. It is anticipated that clustered lesions may play a significant role in cellular response to ionizing radiation since they may present a major challenge to the DNA repair machinery. The degree of lesion complexity increases with increasing LET. This has potential implications for space travel because of exposure to high-LET cosmic radiation. It is therefore critical that we begin to understand the consequences of such damaged sites, including their influence on DNA repair enzymes. This paper presents a short review of our current knowledge of the action of purified DNA repair enzymes belonging to the base excision repair pathway, including DNA glycosylases and apurinic/apyrimidinic endonucleases, on model complex lesions.

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
