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

Normal ankle flexion and extension was inhibited in neonatal rats by applying an adhesive cast on the day of birth such that the tibialis anterior (TA) muscle of one hindlimb was immobilized in a shortened position. Casts were changed daily for 3 weeks, at which time animals were sacrificed. Immobilized TA muscles were significantly lighter in weight, and whole muscle and teased fiber fascicular lengths were significantly shorter. No effects were seen on fiber diameter profiles, total muscle fiber number or muscle cross-sectional area. Immobilized TA muscles had significantly lower phosphofructokinase activities, and lower slow-twitch fibers than contralateral muscles. The mitochondrial enzyme succinic dehydrogenase was unaffected by the reduced activity. It is apparent that, in a developing fast-twitch muscle such as the TA, myofibrillar ATPase histochemical patterns and glycolytic enzyme activity (phosphofructokinase) may be regulated by factors dependent upon neuromuscular activity. Mitochondrial enzymes, such as succinic dehydrogenase, seem to be regulated during development by factors which are not as sensitive to activity.

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.
