Abstract

fetched live from OpenAlex

The basis of the measurement is the reflected signal from the Earth in response to the injected electromagnetic (EM) waveform. The detection of natural resources (such as oil and gas) and pre-earthquake indications by EM signals was pioneered in Canada and the former USSR in 1958. Today this method is used worldwide. The transmitter generates the EM signal, by switching the current into a double pole. The shape of the EM signal determines the amount of information received in the reflected wave from the target area. Detection starts after decay of the transient in the double pole, which means that the transient time-constant should be minimal. The time response is determined principally by the inductive reactance of the double pole. To the best of our knowledge, no electric system that handles more than 200 amperes exists, because of the self induced voltage caused by the transient phenomena in the double pole. We suggest a new circuit to overcome the 200 ampere limit, and thus extend the detected depth.

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.
