Abstract

fetched live from OpenAlex

A simple system capable of measuring the distribution of single molecule activities of a population of E. coli β-galactosidase was developed. This system utilized a modified disposable syringe, a narrow bore capillary tube and an in-laboratory constructed laser-induced fluorescence detection system. Once started, the experiment can continue to collect data without any operator input for more than 24 h. The relative catalytic rates of 138 individual molecules of the enzyme were determined. The distribution of activities was found to be indistinguishable from that reported using more complicated methodologies.

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.
