Abstract

fetched live from OpenAlex

A Carcharodon carcharias (White Shark) was observed attacking and successfully taking a male Phocaena phocaena (Harbor Porpoise) in the Bay of Fundy, Canada at 44°52′93″N, 66°44′32″W at 1600 hours on 17 August 2012, between Grand Manan and The Wolves. The shark was estimated to be greater than 3 m in length. This observation is the first of such incident involving a Harbor Porpoise since 1952. This sighting further contributes to the notion that White Sharks prey upon Harbor Porpoise in the Bay of Fundy.

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.
