Abstract

fetched live from OpenAlex

To understand electrical discharges in gases, and for accurate plasma chemistry modeling, the major input is reliable electron-neutral collision cross section data. To have accurate information assessment, analysis and review of data on cross section in the available literature have been carried out. Each set of data was utilized, and its influence on the swarm parameters such as electron drift velocity or mobility, ionization growth, and diffusion coefficients are investigated. The electric field to gas density ratios (E/N) cover the wide range of 1 to 1000 Td. In support of this effort, finally a set of collision cross sections data for argon was derived. This modified and recommended set of data consisting of momentum transfer, elastic, excitation and ionization cross sections can accurately reproduce the macroscopic observables that are relevant to the real plasmas. Calculation of transport coefficients was carried out by using the numerical solution of Boltzmann equation (Bolsig).

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.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Not 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.
