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

A cover for Scintag's six and twelve-position sample changers was designed and constructed to provide an inert atmosphere for samples during diffraction batch runs. The cover is equipped with inlet and outlet gas ports and fits over the top of the sample changer. Using dry nitrogen gas fed into the inlet of the cover, a sample of lithium bromide was protected from atmospheric moisture for greater than 18 h. The cover uses a thin Mylar window that gives greater than 95% transparency for copper K -alpha X-rays. The cover is a simple device that allows our lab to run multiple moisture-sensitive samples in a batch mode. The simple approach and materials used in the construction of the cover could be applied to other brands of powder diffractometers.

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.

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.
