Abstract

fetched live from OpenAlex

A Josephson oscillator array was investigated through both DC and AC experiments. The simulations and analysis of Yukon and Lin suggested that arrays with three junctions per cell might have unique advantages as high frequency oscillators. These triangular arrays operate with a bias flux of half a flux quantum and power is coupled from the horizontal junctions. This configuration allows one to couple from a whole series of junctions that oscillate in-phase. The power was successfully measured from the horizontal junctions by two different methods. In collaboration with Dr. Cawthorne and Professor Lobb at University of Maryland, an on-chip detector junction was used and Shapiro steps were measured. Also, in collaboration with Dr. Caputo and Professor Ustinov at KFA in Juelich, Germany, a finline antenna was placed across the horizontal row of junctions and coupled power off-chip, to a room temperature receiver. Both experiments demonstrated a proof-of-concept, and future work should include improved matching to measure the maximum available power.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
