Abstract

fetched live from OpenAlex

The purpose of this study was to characterize emulsion preparations made of perfluorooctyl bromide (PFOB) and egg yolk phospholipid (EYP) and their cytotoxicity. Dynamic light scattering and transmission electron microscopy revealed that freshly prepared emulsions stored at different temperatures for a 24-h period have a unimodal particle size distribution with an average particle size of ca. 200 nm. The emulsion displayed a broader particle size distribution following a 14-day storage. Primary human fibroblasts exposure to PFOB/EYP emulsions permanently inhibited cell proliferation and decreased mitochondrial activity. Scanning electron microscopy pictures reveal the presence of spherical particles on the fibroblasts following exposure to the emulsions after thorough rinsing with culture media.

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.

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.
