Abstract
Abstract All‐atom molecular dynamics (MD) simulation combined with chemical shifts was performed to investigate the interactions over the entire concentration range of the ethanol (EtOH)‐water system. The results of the simulation were adopted to explain the NMR experiments by hydrogen bonding analysis. The strong hydrogen bonds and weak C–H···O contacts coexist in the mixtures through the analysis of the radial distribution functions. And the liquid structures in the whole concentration of EtOH‐water mixtures can be classified into three regions by the statistic analysis of the hydrogen‐bonding network in the MD simulations. Moreover, the chemical shifts of the hydrogen atom are in agreement with the statistical results of the average number hydrogen bonds in the MD simulations. Interestingly, the excess relative extent of η rel E calculated by the MD simulations and chemical shifts in the EtOH aqueous solutions shows the largest deviation at x EtOH ≈0.18. The excess properties present good agreement with the excess enthalpy in the concentration dependence.

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
