Abstract

fetched live from OpenAlex

Using the methods described herein, we have demonstrated how scaffolds can be designed for a number of applications including tissue engineering, biomedical devices and injectable tissues. Details on the methods of polymerization and physical and chemical characterization of poly(octamethylene maleate (anhydride) citrate (POMaC) are described. Two POMaC polymer recipes with different monomer ratios of maleic anhydride and citric acid were synthesized and compared. Mechanical testing was performed on scaffolds of two distinct anisotropic designs to show how scaffold design influences the apparent elasticity in the long and short axis. POMaC scaffolds of various patterns and geometries were fabricated to demonstrate: (1) scaffold function can be determined by scaffold design (e.g., inherent shape-memory or self-assembling tubular structures), and (2) the soft lithography approach to fabricating biodegradable elastomers described here can be used to suit a number of different potential applications.

Full frame distilled prediction

Teacher imitation

Not 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.
