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

The distribution of Manganese bacteria(MnB)in 10 sediment cores from the Canada Basin and the Chukchi Sea were analyzed by the methods of MPN and plate culture.The cores were sliced in 1 cm intervals from 0~10 cm and at 2 cm intervals below 10 cm on board as subsamples.Retrievability of MnB cultivated in both 4℃ and 25℃ ranged from non-detectable levels(ND)to 3.3×108 CFU·g-1 of wet sample.The occurrence percentages and average numbers of MnB cultivated at 4℃ and 25℃ were 77.78%,5.60×106 CFU·g-1 wet samples,and 86.03%,7.91×106 CFU·g-1 wet samples,respectively.The contents of MnB in sediment cores were higher than those in sediment from the deep Pacific Ocean or in water from Alaska Lake,similar to the results reported in water from the Carlsberg Ridge in the Indian Ocean.The result showed that a tendency of the MnB content increasing from low latitude to high latitude,or from the shallower continental shelf to deeper basin in the south of 78 N.From the surface to deeper sediment,the content of MnB in sediment changed irregularly,depending on the sedimentary environment.It seems that the variability of MnB content was larger at 25℃ than at 4℃.

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.
