Abstract
The water uptake of poly( dl -lactide) (PLA) and its copolymer with glycolic acid (PLGA 50:50) has been studied using a quartz crystal microbalance (QCM). The polymers were swollen in humid atmospheres at 20 °C in order to probe both the kinetics of adsorption and the equilibrium amount of water taken up at low concentrations. The relative humidity of the air was controlled using saturated salt solutions. By equating the chemical potentials of the water vapor and the polymer/water mixture at equilibrium, it was possible to extract the Flory−Huggins interaction parameter χ from a simple binary mixing theory. Studies were also performed on the formulations of these materials with a model polypeptide active ingredient. The kinetics of swelling were described using a model based on the Thomas−Windle model of penetrant diffusion in glassy polymers.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
