Abstract

fetched live from OpenAlex

Beamforming using a microphone array mounted on the surface of a rigid or impedance sphere and cylinder is discussed. The introduction of a structure into the space occupied by or immediately adjacent to the array gives the array an effectively larger aperture and the possibility of enhanced performance. Additional improvements can be obtained through the introduction of a surface that permits air-coupled surface waves to propagate. Since surface waves travel at a speed less than the speed of sound in free space, the aperture of the array can be effectively further increased.

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.
