Abstract

fetched live from OpenAlex

Summary form only given, as follows. High-energy-density laser-produced plasmas offer an unique window for the investigation of high pressure phenomena. From observations of the intensity of optical emission from and the reflectivity of a plasma generated by a laser-driven shock wave, one learns about not only the rate of thermal equilibriation between electrons and ions in a strongly coupled plasma but also the state of two-temperature nonequilibrium that exists in a shock wave. Or, one may use the K-shell photoabsorption spectrum in similar plasmas to test our understanding of pressure ionization processes. Alternatively, a plasma produced by the isochoric heating of an ultrathin foil using an ultrashort pulse laser can be used to assess the equation of state at high pressure.

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.
