Abstract
Abstract The ability of Bi n + cluster ion sources to provide information about the physical structure of an integrated film composed of oligonucleotides and non‐nucleic acid oligomers of poly(2‐hydroxyethyl methacrylate) (PHEMA) has been explored using static time‐of‐flight (ToF) SIMS (ToF‐SIMS). Fragment intensities from PHEMA and oligonucleotides were compared. Negative ion spectra indicated that the Bi 5 + source provided details that were either not apparent or at much reduced sensitivity when using Bi 3 + and Bi + sources. The Bi 3 + ion source provided higher secondary ion intensities for positive ion fragments, and more than 200‐fold selectivity for ionization of oligonucleotide in comparison to PHEMA when in mixture, even though the oligonucleotides were not immobilized as a coating superimposed on PHEMA.

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
