Abstract

fetched live from OpenAlex

Antiviral and anti-inflammatory activities are important for the prevention and treatment of respiratory tract infections. These activities can be found in the herbal medicinal plant Echinacea purpurea (EP). However different commercial preparations of EP vary greatly in chemical composition and the manufacturing procedures used, and consequently differ significantly in their antiviral potencies. As a result, there is no standard procedure for the preparation of consistent high potency extracts. In this study we evaluated different types of EP extracts for relative antiviral activities.

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.
