Abstract

fetched live from OpenAlex

As the ability to quantify contaminant uptake and clearance from individual organisms improves and modeling efforts are devoted to describing transport in increasingly complex food webs, including vegetation, there is a need to establish a consistent framework within which contaminant sources and transfer in food webs can be characterized. It is shown that a convenient and general framework is established by compiling the set of mass balance equations describing uptake in each organism by food and respiration in a matrix format using the fugacity concept. The matrices and vectors can be manipulated to gain valuable insights into how contaminant concentrations in the four abiotic media of air, water, soil, and sediment translate into concentrations in organisms throughout a food web. The framework is illustrated for a simple six organism food web including aquatic, terrestrial, and avian species. Methods of obtaining input parameters are outlined, and advantages of the approach are discussed.

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.
