Abstract
Molecular dynamics simulations are carried out in a systematic manner to develop a coarse grain model for multiple-of-three carbon n-alkanes. The procedure involves optimizing harmonic bond and bend parameters, and Lennard-Jones nonbonded parameters, to match observables taken from fully atomistic simulations and from experiment. The experimental values used consist of surface tension and bulk density data. Scaling relations are introduced to allow for the representation of the remaining n-alkanes. As n increases these relations converge to the multiple-of-three carbon values. The model is assessed by comparing it to both fully atomistic simulation and experimental data which was not used in the fitting procedure.

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
