Abstract

fetched live from OpenAlex

A two-dimensional chromatographic detector, featuring rapidly acquired spectra and employing laser induced fluorescence with a CCD camera, is described. The detector response is linear over four orders of magnitude and features a detection limit of less than 10−9 M for anthracene. The normal wavelength range recorded is 250 nm, extending from about 335 to 585 nm using the 325 nm line of a He-Cd CW laser. Spectral acquisition times range from 1 to 10 seconds. An autoranging feature extends the linear dynamic range of the detector to over 5 million. The detector is most useful for the analysis of naturally fluorescing materials in complex mixtures.

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.
