Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

This study uses electrical resistivity tomography (ERT), recently introduced as a means of detecting contaminants in the subsurface, to detect oil pollution of sand. A total of 28 stainless steel stakes were placed in a tank filled with Ottawa sand having a moisture content of 2.5%. The stakes were connected to the electrodes of the Advanced Geosciences Inc. (AGI) Supersting R1. Several control surveys were run to obtain the electrical resistivity of the sand before and after application of the contaminant. Engine oil was poured at the surface point to observe changes in the electrical characteristics at the entry spot. Several tests were performed on different days to investigate how the contamination affected resistivity. Locations with oil concentration showed no major changes in electrical resistivity over a period of 7 days. ERT surveys were found useful in detecting oil plumes and their flow in sand.

Full frame distilled prediction

Teacher imitation

Not 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.
