Abstract
Hydrogels with tunable hydrophilic and mechanical properties were synthesized by the free radical polymerization of 2-hydroxyethyl methacrylate (HEMA) and 2-methacryloyloxyethyl N-butylcarbamate. The resulting hydrogels were investigated for their equilibrium water content, sessile drop water contact angles, gel fraction, mechanical properties and protein adsorption. Results indicated that co-polymer hydrogels have good hydrophilicity and that, with the incorporation of the 2-methacryloyloxyethyl N-butylcarbamate, mechanical properties could be improved significantly. without affecting other important properties. Lysozyme and albumin adsorption experiments demonstrated that, similar to most hydrogel materials, the co-polymer hydrogels adsorb more lysozyme than albumin and that the adsorption was dependent on hydrophilicity. The control poly(HEMA) hydrogels were found to adsorb more protein than the co-polymer hydrogels; this is thought to be primarily a consequence of protein absorption rather than protein adsorption.

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
