Abstract

fetched live from OpenAlex

The quantification and reporting of the analytical uncertainty that accompanies all stable isotope measurements is critical, providing a mechanism for assessing their comparability against other datasets. The ability to compare isotopic datasets generated across many labs is especially important as there has been a proliferation in the number of stable isotope databases across a range of disciplines, facilitating large scale metanalyses of a rapidly expanding library of isotopic measurements. This paper presents a simple and automated spreadsheet-based approach for quantifying and reporting analytical uncertainty of stable isotope measurements. • Automated spreadsheet for determining analytical uncertainty. • Uncertainty robustly captures random and systematic error. • Highly expedient, requiring minimal copying and pasting.

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.

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.
