Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Full frame distilled prediction
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)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
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.

Abstract
Abstract A continuum‐atomistic adaptive multiscale method is developed for the simulation of the dynamics of dislocations. Two key features of the method are (i) methods for both refining and coarsening the model, where coarsening refers to a continuum to atomistic transition and refinement to the opposite and (ii) error criteria for refining and coarsening. In coarsening of edge dislocation solutions, it is crucial to capture the discontinuities across the glide plane, which is accomplished here by the extended finite element method. Error criteria are developed in terms of energies so that the atomistic model tends to follow the core, where continuum models are generally quite inaccurate. The method is applied to two‐dimensional problems involving dislocations emitted from a void and from a crack tip. The results show good agreement with other multiscale methods and result in a large savings in computational effort. Copyright © 2011 John Wiley & Sons, Ltd.
