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.

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

In this paper , the basic principle,application,progress in development and reseach of various quantum magnetometers, have been reviewed briefly. In authors' opinion, the quantum magnetometers include nuclear precession magnetometer(proton, He3) , Overhauser - Abraham proton magnetometer , optical pumping magnetometer (He4、K、Cs、Rb), atomic magnetometer and superconducting magnetometer. This paper is involved with five kinds of magnetometers in more details. 1) Overhauser - Abraham proton magnetometers made in France and Canada , would be successor of common proton magnetometer. 2) New He4 optically pumping magnetometer, developed by french J. M. Leger et al, using laser with D0 line as light source (Dr. R. E. Slocm et al. in America have done similar work independently. ) , offers good sensitivity and accuracy. The deviation from omni -directionality is small. It is suggested to ESA to use this type of magnetometer for satellite magnetic measurement.3) Alkali vapour magnetometers(K、Cs、Rb), using lamps with D1 line as light source, are widely applied in geophysical survey. 4) The all -optical magnetometer developed by M. V. Romalis, J. C. Allred et al. , sensitivity of 0. 54fT/Hzl/2(lfT=10-15T) has already been a-chieved, and 10-18 T could be reached. 5) Superconducting magnetometer (SQUID) when working below 4°K, is the most sensitive, and the HTC SQUIDs , recently made in America and Europe, are portable, and can be used for magnetic and EM surveying.

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.
