Abstract

fetched live from OpenAlex

From the master equation we derive the equation for the time evolution of the local density in terms of correlation functions. In the long-time and large-scale limit we use a gradient expansion together with the assumption of local equilibrium to derive an analytical expression for the density and temperature dependence of the diffusion coefficient. For various choices of the detailed kinetics and with the inclusion of first and second neighbor and trio interactions we show explicitly that the Reed-Ehrlich factorization holds exactly, we give explicit results and discuss their implications for the understanding of experimental results. We compare our method to existing analytic approaches and indicate its extensions.

Full frame distilled prediction

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.
