No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

The aim of this work was to assess the mixing, transfer and handling, properties, injectability, set time, wash-out characteristics, acceptance of hardware (i.e. stainless screws), and their delivery/transfer systems of self hardening synthetic bone cements made from calcium phosphate and calcium sulphate. Surgical procedures (i.e. cranioplasty) were performed on adult Labrador dogs using seven different bone cements from various manufacturers. Direct comparison of the defined intraoperative properties were evaluated and recorded. There is considerable variability with respect to application properties among commercially available injectable synthetic bone cements. Only one product was rated good to excellent in seven of the eight categories evaluated (6-excellent, 1-good, 1-fair) based on in-vivo tests. This study outlines the critical parameters required for successful implantation of cements that have to be understood when designing new injectable bone cements for the future.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
