Abstract
We report the use of optical coherence tomography (OCT) for measuring dextrorotatory-glucose (D-glucose) in liquid phantoms and in drawn blood based on temporal dynamics of light scattering. The presence of D-glucose alters the medium viscosity, thus affecting the Brownian motion of the scatterers (polystyrene microspheres (PMS) in phantoms, red blood cells (RBCs) in blood) as measured by OCT. To quantify the effect, the signal autocorrelation functions were measured from M-mode OCT data and exponentially fit to obtain the decorrelation times. These were then related to translational (and rotational, in case of asymmetric scatterers) diffusion coefficients which enabled the determination of D-glucose-controlled medium viscosity. Obtained viscosily values agreed well with the literature, and showed expected increase with D-glucose concentrations. Whole blood smears were imaged with microscope and another effect of added glucose, that of red blood cell deformation, was also observed. This phantom and blood OCT study demonstrates the technique’s ability to detect and quantify D-glucose presence in non-flowing liquid suspensions, and suggests several additional research routes necessary to determine its potential for in vivo applications.

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
