Abstract

fetched live from OpenAlex

Over the decades, a plethora of boundary integral equations (BIEs) have been formulated to tackle the increasingly challenging problems faced by o.a. design engineers of electronic circuits and components. Despite their clear advantages such as a reduced matrix size and automatic inclusion of unbounded background media, BIEs often suffer from detrimental characteristics, i.e. low-frequency or dense-mesh breakdown, and internal resonances. As this detrimental behavior can emerge inherently or due to a particular discretization scheme, it is important to investigate such properties of promising formulations thoroughly to devise breakdown-free solutions and alternatives. For single-source BIEs, these analyses are remarkably more sparsely populated compared to the more conventional BIEs.

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.

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.
