Abstract
ABSTRACT The preliminary results of a study on the applicability of using spectrophotometry of the culture medium toward understanding of cells' response to different environments is reported. The cells are cultivated on polydimethylsiloxane (PDMS) substrates and physicochemically manipulated by varying the substrate stiffness and the dose of surface plasma treatment. By growing cervical cancer (HeLa) cells on PDMS with varying stiffness and plasma treatment levels, we tested the hypothesis that the influence of substrate stiffness and treatment can be detected through the spectrophotometry of a microvolume of cell culture medium. The results imply an opportunity of using the spectrophotometry of culture media with an integrated minimal sample retention system as a practical and noninvasive alternative to traditional bioassays requiring cells detachment.

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
