Abstract

fetched live from OpenAlex

This paper presents a new hybrid node that is used with the diakoptic method for the frequency-domain transmission line matrix (FD-TLM) modeling. The new node is derived directly from the conventional symmetrical condensed node but without stubs that account for medium permittivity and permeability. Therefore, it has the same numerical properties as those of the frequency-domain symmetrical condensed node (SCN) method but requires less memory. Together with the diakoptic method, it allows a structure to be decomposed into several sub-domains which can be simulated and stored separately. Preliminary numerical examples are presented to demonstrate the efficiency of the proposed node and the diakoptic method.

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.
