Abstract

fetched live from OpenAlex

The running diffusion coefficients are evaluated using Langevin equations in order to describe the transport of guiding centers of charged particles perpendicularly to the main magnetic field in the case of a two-temperature plasma. The stochastic transition between the two temperature states is described by a randomly interrupted noise. The radial variation of the running diffusion coefficients is discussed for two cases of the radial profile of the two temperatures for different collisional regimes. The values of the diffusion coefficient depend not only on the features of the two temperature profiles but also on the parameters of the random transition.

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.

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.
