Abstract

fetched live from OpenAlex

In this work, a reversed-phase monolithic column was permanently coated with didodecyldimethylammonium bromide (DDAB) to perform ultrafast separations of iodate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate in as little as 30 s. Separations were performed using 6 mM o-cyanophenol (pH 7.0) at flow rates up to 10 ml/min and suppressed conductivity detection. Detection limits in the parts-per-billion range were observed for all anions studied (e.g., ranging from 30 ppb for phosphate to 4 ppb for sulfate). The reproducibility was 0.7 and 0.4% RSD for retention time and peak area, respectively. Coated columns were stable for up to 12 h of continuous use at 5 mL/min (i.e., 1-min separations).

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.
