Abstract
In this paper we investigate the effectiveness of an alternative design scheme to reduce the AC losses in high temperature superconducting (HTS) power transmission cables made of non-ferromagnetic HTS coated conductors. With this design, the adjacent tapes of each layer of the cable overlap each other up to a certain distance from their edges, typically 1 or 2 mm. Using two different numerical methods, an integral technique and a finite element method, we performed a parametric investigation of the idea of overlapping the tapes in the case of a single layer HTS power cable. Through the simulation results, we show that overlapping the tape leads to an important reduction in the AC losses of the cable (typically two to five times), mostly due to an advantageous redistribution of the current in the tapes.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
