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

Air-jet vacuum pump as the pneumatic source of a coach toilet provides the negative pressure to pump the sewage out of toilet bowl via the compressed air passing through the pump under cretain pressure.The software FLUENT was used for the unsteady numerical simulation of the flow field inside the vacuum toilet system to analyze the effects of ratio of areas,distance between De Laval nozzles,length of uniform-section mixing chamber,taper angle of diffusion segment and both lengths of the contraction and diffusion segments of nozzle throat on the remaining pressure in suction chamber.A reference is thus provided theoretically to the design of such air-jet vacuum pumps.

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.
