Abstract

fetched live from OpenAlex

Pictures of an atmospheric pressure arc between two concentric copper electrodes at different external magnetic fields (B field) were taken using a charge-coupled device camera and a complementary metal-oxide-semiconductor camera. The pictures reveal splitting of the arc column into a column with multiple arc roots (i.e., cathode spots), repulsion of cathode spots due to their self-induced B fields, and grouping of cathode spots under the influence of B field. Power frequency spectra analysis of the voltage fluctuations was also performed.

Full frame distilled prediction

Teacher imitation

Not 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.
