Abstract

fetched live from OpenAlex

In this paper, a cavity backed spiral antenna is introduced. The antenna is a four-arm Archimedean spiral antenna. To effectively direct the radiation in the upper half space region, the spiral antenna is backed by a conducting cavity, which is peripherally filled by an absorber ring. Antenna radiates circularly polarized waves. The height of the surrounding cavity is only 7mm, which leads to an extremely low profile structure. The polarization purity and antenna gain are investigated over a wide frequency bandwidth of near 1 to 8GHz.

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.
