Abstract
In this paper, we consider a thermoelastic contact problem in which the heat exchange boundary condition is affected by normal displacement on contact boundary, and the operator in the nonlinear thermoelastic constitutive law is considered to rely on temperature field.First, we deliver the weak formulation of the thermoelastic contact problem which is a coupled system formulated by two variational inequalities with constraints.Then, by employing the Tychonoff fixed point theorem for multivalued operators, an existence theorem for the thermoelastic contact problem is established.Finally, a family of approximate penalized problems corresponding to the thermoelastic contact problem is introduced, and a convergence result is proved.The latter indicates that the solution set of the thermoelastic contact problem can be approached by the solution sets of approximate penalized problems in the sense of the upper semicontinuity property of Kuratowski.

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
