Abstract

fetched live from OpenAlex

A narrow focus ultra-wideband dielectric-filled antenna has been designed for the purpose of near-field breast cancer detection without the use of coupling media. Instead of immersing the antenna in a lossy liquid coupling medium, direct matching of the substrate and antenna to the biological tissue is proposed here. The proposed feed structure was designed on low-cost printed-circuit-board (PCB) with alumina substrate and the antenna radiating section on HIK dielectric material. A design procedure for the antenna is outlined. The aperture size was 0.1 cm by 6.35 cm. A return loss less than 5 dB from 2 to 10.6 GHz and a minimum return loss of 10 dB was obtained from 4.6 to 10.6 GHz. The antenna had simulated near-field narrow beam with half-power beamwidth of 10.3deg.

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.
