Abstract

fetched live from OpenAlex

Abstract While conducting overline surveys including Close Interval Survey (CIS), Alternating Current Voltage Gradient (ACVG), Direct Current Voltage Gradient (DCVG), Alternating Current Current Attenuation (ACCA) and Depth of Cover (DoC) in the Southeast Saskatchewan, Canada, a section of the cross Canada/US border Alliance pipeline, an unexpected CIS potential was encountered whereby potential measurements dipped, falling below the -850mV potential criteria, before rising again back into the range before the drop. The location of the potential drop occurred at a foreign crossing thus stray current was initially suspected. The field crew remained nearby while the foreign crossing owner representatives were notified of a possible interaction requiring further investigation. An interruption and influence analysis plan was put together to determine the nature of the influence on the Alliance DC Potential measurement circuit. This paper summarizes the preliminary analysis and test plan, the field measurements, and results.

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.
