Abstract

fetched live from OpenAlex

This paper examines and compares research activities in the field of lake sediment analysis for the period 2000-2009. The scientometric data is collected from 79 articles published in major journals included in the Science Citation Index (SCI). The most commonly used journals were Science of the Total Environment, Chemosphere, Microchemical Journal, Applied Geochemistry and Environment International. The trace elements which are analyzed in most cases are Pb, Cu, Ni, Cr, Co, Mn and Zn. None of countries show research effort activity that would be outstandingly higher than the majority, although some of them, eg Sweden, The United States, Canada and China have shown activity above the average level.

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.

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.
