Abstract
With data from in vitro and in situ investigations, we developed a mathematical model to describe cellular uptake of uranium and arsenic in solution by living Lemna gibba under homeostatic regulation. The model considers the ability of healthy cells to resist accumulation of toxic metal species by regulating physicochemical properties of the cell membrane. In the bulk solution, the ratio of the total amounts of bioavailable metal ions to the metal ions uptake by the cells is very high. Consequently, the main rate-limiting processes of uptake are the biosorption kinetics on both external and internal surfaces at the biological interface, and the transport of the metal ions across the cell membrane. The model prediction correlates well with uptake results from field and microcosm experiments for uranium and arsenic by L. gibba, a model ecotoxicological test organism.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
