N-Alkylacrylamide copolymers with (meth)acrylamide derivatives of cholic acid: Solution properties and aggregation
Bibliographic record
Abstract
Abstract Solution properties of a series of thermosensitive copolymers based on acrylamide and methacrylamide derivatives of cholic acid and N-alkylacrylamides such as N,N-diethylacrylamide, N-ethylacrylamide, and N-isopropylacrylamide have been studied by various techniques including fluorescence and turbidimetry. These copolymers contained 1 - 5 mol-% of the (meth)acrylamide derivatives of cholic acid as determined by NMR spectroscopy. A two-stage aggregation process was observed for the copolymers of N-isopropylacrylamide when the number of cholic acid residues was sufficiently high. The presence of the copolymers lowered the critical micellar concentration of sodium dodecyl sulfate but had little effect on the micellization of sodium cholate. The critical micellar concentration of these copolymers decreased with increasing content of cholic acid residues in the polymers.

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.
