Abstract
Effects of tungsten material used as high voltage needle electrode on the production of hydrogen peroxide and degradation of dimethylsulfoxide by the pulsed corona discharge in water have been investigated. Reactor of needle-plate electrode geometry was used. Erosion of tungsten electrodes by the discharge was evaluated. The yields of H2O2 production and decomposition of DMSO by the discharge obtained using tungsten electrodes were compared with that determined for titanium electrodes. The electrode erosion increased significantly with the increasing solution conductivity. Large fraction of the tungsten material released from the tungsten electrode by erosion in the discharge was determined in the solution in dissolved form as tungstate ions. Tungstate ions were shown to play dominant role in the decomposition of H2O2 produced by the discharge with tungsten electrode. Higher degradation of DMSO determined for tungsten was attributed to the tungstate-catalyzed oxidation of DMSO by H2O2

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
