Abstract

fetched live from OpenAlex

The interaction of like-charged walls immersed in aqueous solutions with monovalent counterions is investigated at the McMillan–Mayer (MM) level of description. The net pressure acting between the walls is obtained by applying the anisotropic hypernetted-chain theory. The MM approach requires solvent-averaged ion–ion potentials of mean force as input. Results based on “realistic” models for Na+ and Cl− in water are available in the literature and these are used in the present calculations. The wall–wall interactions obtained can differ dramatically from the primitive model (dielectric continuum solvent) case. For some models attractive wall–wall forces are observed at small separations. The MM theory is found to be rather sensitive to details of the counterion–counterion potential of mean force, and different models for the same counterion can give qualitatively different results. At present it is difficult to evaluate the relative accuracy of the different models that have been proposed. However, the results presented here give at least an idea of the interesting possibilities that lie in the physically realistic range.

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.
