Abstract
The enzymatic degradation of hyaluronic acid (HA) and carboxyl-modified chitosan (CC) polymers in aqueous dispersions can be controlled by dynamic covalent cross-linking. Unlike un-cross-linked HA, dynamic covalent cross-linking preserves the viscoelastic behavior of HA dispersions when exposed to hyaluronidase enzyme. Among the dynamic covalent cross-linked CC dispersions, only dispersions with degrees of deacetylation of 98% (CC98) partially upheld the viscoelastic behavior under lysozyme-mediated degradation. Overall, our results suggest that dynamic covalent cross-linking can produce injectable HA and CC dispersions with partial enzymatic degradation resistance.

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
