Abstract
Abstract An impedimetric method of detection of gadolinium(III) free species has been developed using gold electrodes functionalized by terpyridine ligands. Two chemical attachment processes, on an acidic thiol and on an aminothiol, were designed and the sensitized surfaces were then characterized by chemical analyses, physicochemical and electrochemical methods. The detection of Gd 3+ was investigated by impedance spectroscopy. A linear calibration curve was obtained from the variation of the polarization resistance versus pGd 3+ in the range 10 −8 M to 10 −3 M. The impedimetric sensor presented a shelf life of more than six months. Moreover, Gd 3+ detection in spiked diluted real urine samples was satisfactorily performed.

Full frame distilled prediction
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
