Abstract

fetched live from OpenAlex

The molecular in-plane and out-of-plane structure of dimyristoylphosphatidylcholine (DMPC) membranes containing up to 60 mol% of cholesterol was studied using X-ray diffraction. Up to 37.5 mol% cholesterol could be dissolved in the membranes, resulting in a disordered lateral membrane structure. Highly ordered cholesterol structures were observed at cholesterol concentrations of more than 40 mol% cholesterol. These structures were characterized as immiscible cholesterol plaques, i.e., bilayers of cholesterol molecules coexisting with the lipid bilayer. The cholesterol molecules were found to form a monoclinic structure at 40 mol% cholesterol, which transformed into a triclinic arrangement at the highest concentration of 60 mol%. Monoclinic and triclinic structures were found to coexist at cholesterol concentrations between 50 and 55 mol%.

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.
