Abstract

fetched live from OpenAlex

Surface acoustic wave devices can be used to implement matched filters in direct-sequence code division multiple access systems, where they can provide the equivalent of over 1 Tflop computation power. In particular, they are naturally able to process long sequences employing real-valued components. In this paper, we describe the derivation of families of real-valued sequences that offer the benefits of improved auto-correlation and cross-correlation performance, while offering a larger number of codes than traditional binary sequences.

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.
