Two phase coexistence in ternary mixtures of saturated and polyunsaturated phosphatidylcholines with cholesterol
Bibliographic record
Abstract
Combining 2 H and 14 N nuclear magnetic resonance measurements on ternary lipid/cholesterol mixtures it is possible to quantitate the phase separation into coexisting ℓ o and ℓ d domains using a single sample whose composition is within the two phase region. Mixtures of each of the unsaturated phospholipids dioleoyl phosphatidylcholine, dilinoleoyl phosphatidylcholine and dilinolenoyl phosphatidylcholine with the saturated dipalmitoyl phosphatidylcholine and cholesterol all exhibit ℓ o and ℓ d phase coexistence over a substantial range of compositions and temperatures. A higher degree of unsaturation broadens the temperature range of two phase coexistence and results in the ℓ d phase domains actually being significantly more ‘fluid’ at lower temperatures than they are at higher temperatures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
