Abstract

fetched live from OpenAlex

Abstract The arsenic species in male and female sea scallop gonads ( Placopecten magellanicus ) at pre‐spawning and post‐spawning stages, collected near Newfoundland, Canada, were characterized by using high‐performance liquid chromatography–inductively coupled plasma‐mass spectrometry. All samples contain arsenobetaine (0.5–3.0 µg g −1 ) and a dimethylarsinoylriboside derivative as the major water‐soluble arsenic compounds. Male pre‐spawning gonads contain 0.35–2.4 µg g −1 of the dimethylarsinoylriboside. Female pre‐spawning gonads contain 0.47–9.64 µg g −1 of the same compound. Post‐spawning gonads, both male and female, contain higher concentrations of this compound (3.7–11.4 µg g −1 ). The total concentrations of water‐soluble arsenic compounds are different in male and female pre‐spawning gonads. These differences are not obvious in post‐spawning gonads. Post‐spawning gonads contain higher total concentrations of water‐soluble arsenic compounds than pre‐spawning gonads. Copyright © 2001 John Wiley & Sons, Ltd.

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.
