Cold argon plasmas for non-enzymatic digestion of proteins and peptides dataset
Bibliographic record
Abstract
Data from the paper 'Cold argon plasmas for non-enzymatic digestion of macromolecules' by McGill et al, 2025. Results were generated by exposure of standards to a cold argon plasma, followed by mass spectrometry analysis. Please see the associated article for experimental procedures.Beta-casein data:Beta-casein - LC-MS (control, 30 seconds exposure at 10% duty cycle)Haemoglobin data:Haemoglobin - LC-MS (control, 30 seconds exposure at 10% duty cycle)Haemoglobin - direct infusion ECD MS/MS (full spectrum, 1004 m/z isolated, 1004 m/z ECD, 1064 m/z isolated, 1064 m/z ECD)Peptide data:Leucine enkephalin - direct infusion (control, 5, 30, 60 seconds exposure)Bradykinin - direct infusion (control, 5, 30, 60 seconds exposure)Angiotensin I - LC-MS (control, 30 seconds exposure at 10% duty cycle)Ubiquitin data:Ubiquitin - LC-MS on Bruker solariX (control, 30 seconds exposure at 10% duty cycle)Ubiquitin - LC-MS on Bruker ImpactHD (control, 30 seconds exposure at 10% duty cycle)Ubiquitin - CID MS/MS after exposure to plasmaAll files are in Bruker .d format.
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
