Abstract

fetched live from OpenAlex

Plasmas were produced by laser-induced breakdo wn in nitrogen, oxygen and air at 1 atm using the 1.06 μm beam from an YAG la ser .The spectra of these plasmas in the range of 400-800 nm were obtained. The preliminary result shows that all the spectra consist of a strong continuous ba ckground and some line structures. With delay sampling, the spectra vary remarka bly. By sampling at the different position of the plasmas, the spectra change in a special way. The quantitative analysis is in progress.

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.

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.
