Abstract

fetched live from OpenAlex

The combination of liquid chromatography and mass spectrometry LC-MS) is a powerful tool for the detection and quantitation of phycotoxins in plankton and shellfish at trace levels, the identification of new toxins, the investigation of toxin production by plankton, and the study of toxin metabolism in shellfish. Progress in development of LC-MS as a “universal” toxin analysis method for the comprehensive analysis of a wide range of toxins is now described. Two basic methods have been developed: lipophilic toxins are separated on a reversed phase column using gradient elution, while the paralytic shellfish poisoning (PSP) toxins are separated on a hydrophilic interaction LC column using isocratic elution.

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.
