Abstract
In the present paper, we report a comprehensive study of the effect of the annealing temperature in the ultra-high vacuum on icosahedral (i)-Al-Pd-Mn surface using low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). The preparation of the i-Al-Pd-Mn surface is important for growing elemental quasiperiodic layers. The LEED pattern of i-Al-Pd-Mn shows diffraction spots with a high background after annealing at 823 K whereas sharp spots with less background are observed when annealed at 923 K. On the other hand, STM shows the presence of clusters with diameters of 5 to 40 nm and heights of 1 to 10 nm after annealing at 823 K whereas cluster-free wide and flat terraces are observed after annealing at 923 K. Thus the importance of annealing at the higher temperature of 923K is shown.

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
