Abstract

fetched live from OpenAlex

A mathematical model for interpreting experimental data obtained from ramped voltage testing of transformer oil is presented. Current is perceived to flow alternately by convection and conduction when the electric field strength is high enough to initiate detrapping of electrons and field dissociation. Homopolar injection of electrons and positive ions is considered to delineate two regimes in which space-charge-limited current is directly related to a simple power of the applied potential. The injection process leads to the launching of solitary waves of the sine-Gordon type from each electrode and detrapping occurs within the wavefront of these. In direct response to this the remaining trapped electrons reorganize into a Beltrami flow field contained within small cells which coincide with the Debye spheres that are pertinent to the electrostatics of the free charge population. These cells act as quasiparticles passing through the dielectric liquid with which they interact to sustain the electrohydrodynamic flow which constitutes their drift motion as carriers in the applied field.>

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.
