Degradation during ARXPS measurements of polystyrene treated with an oxygen plasma
Bibliographic record
Abstract
Abstract Thin polystyrene films, deposited on glass substrates, were exposed to an oxygen / helium plasma for 3s, 7s, 15s or 30s. Following exposure to air for four weeks, the samples were analyzed by ARXPS in a VG ESCALAB 220i X‐ray photoelectron spectrometer and in a VG Theta Probe instrument. Comparison of the results obtained demonstrates the effect of the oxygen loss during analysis in the VG ESCALAB 220i, which flattens the angle‐resolved profiles obtained and leads to the calculation of an oxygen depth profile which extends deeper into the surface and in which the oxygen concentration is lower. A simple procedure for the correction of the data obtained in the VG ESCALAB 220i is only partially successful at reconciling the derived oxygen depth profile with that calculated from the Theta Probe data.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
