Abstract
Abstract The purpose of this study is to determine the electromyogram response of the cervical muscles to a right lateral impact when the trunk is flexed. Twenty healthy volunteers were subjected to right lateral impacts of 4.1, 8.0, 11.1, and 13.3 m/s2, and were seated ȁout-of-positionȁ with the trunk flexed forward by 45 degrees and also either right or left laterally by 45 degrees. Muscle responses were of low magnitude, all muscles generating less than 39% of their maximal voluntary contraction electromyogram. The splenius capitis muscle contralateral to the impact direction showed a greater EMG response than its counterpart. Electromyographic and kinematic variables showed trends towards being affected by the levels of acceleration. Time to onset of the electromyogram for the muscles decreased with increasing levels of acceleration. Overall, a right lateral impact with subjects ȁout-of-positionȁ reduces the muscle activity and perhaps the risk of muscle injury as compared to when subjects are in neutral (driving) posture.

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
