Abstract

fetched live from OpenAlex

Particle filled composite and interpetrating phase composite (IPC) structures are investigated for the production of a biodegradable composite for use as a fixation device in various osteosynthesis applications. The composites consist of calcium polyphosphate, present as either a dispersion of 106 – 150 µm particles or as a sintered scaffold-like structure having open porosity in the range of 18 – 35 volume percent, and a polyvinyl acid-carbonate copolymer that is cured in situ via free radical polymerization. The performance of each composite structure is evaluated in terms of its three-point bend strength and elastic constant. Plane strain fracture toughness values are also presented for IPC samples based on CPP sintered to have 30 volume percent porosity.

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.
