Abstract

fetched live from OpenAlex

Due to the finite sizes of the patches in the patch array of a microstrip reflectarray, the phase errors attributed to this size factor is generally significant at large subtended feed angles, since a large difference in the phase delay exists across the dimension of each patch. The larger the patch dimension is, the larger the phase error becomes, especially at large subtended feed angles. This will degrade the reflectarray performance. Nevertheless, such phase errors are reduced by increasing the F/D ratios, and by employing small patch dimensions as much as possible.

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.

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.
