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.

fundA Canadian funder is recorded on the work.
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

For reasons that are not well understood, there are permanent enhancements in the neutral mass density in Earth's thermosphere in the vicinity of the northern and southern geomagnetic cusps, and at altitudes of around 400 km. Such enhancements are expected to cause small but important and currently unpredictable perturbations to the orbits of spacecraft flying through them. Here we report on a NASA sounding rocket mission to study mechanisms responsible for establishing and maintaining these enhancements. On November 24, 2014, a Black-Brant 12 sounding rocket was launched from Andoya Space Center out over the Greenland Sea, and into the enhancement region associated with the ionospheric footprint of the northern geomagnetic cusp. It released ten rocket-propelled "grenades" that dispersed barium strontium tracer clouds into the thermosphere throughout a 3D volume extending over many tens of km around the main trajectory, and spanning heights from 190 to 400 km. Subsequent motions of the ionized barium and neutral barium/strontium components of the clouds were determined by photographic triangulation, using cameras based at Longyearbyen, Ny-Alesund, and aboard a NASA aircraft flying just south of Svalbard. Initial results of this analysis will be presented, and the implications for the mechanism(s) responsible for the density anomaly will be discussed.

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.
