Abstract

fetched live from OpenAlex

The Acknowledgements in the article, ‘The accuracy and reproducibility of SPECT target volumes and activities estimated using an iterative adaptive thresholding technique,’ which published in the December 2012 issue of the journal, were stated incorrectly 1. The correct Acknowledgements should read as follows: Acknowledgements This work is supported in part by a scholarship from the province of British Columbia through the Ministry of Advanced education (Pacific century Graduate Scholarship) and by a grant from the Polish Ministry of Science and Higher Education no. NN4 02 456738/no. agreement 3664/B/PO1/2010/38.

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.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
