Abstract

fetched live from OpenAlex

A computational model is proposed to analyze the nanoscale self-assembling phenomenon of monolayers on heterogeneous surfaces. Morse potential is used to describe the pairpotential between molecules or atoms. Minimization of free energy is used to regulate different phases and lattices to form optimized heterogeneous structures of different sizes with periodical patterns. A representative volume element (RVE) is first defined and an optimization algorithm is developed to adjust the positions of particles in it to reduce its potential until global equilibrium is reached. The pair-potential distribution in the monolayer and the substrate layers are studied. It is interesting to observe that the pair-potential distribution in the substrate layers resumes uniformity just a few layers away from the interfacial boundary.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
