Abstract
Abstract Linear and circular degree of polarization (DOP) trends are studied in microsphere suspensions ranging from the Rayleigh regime (sphere diameter << λ) to larger sizes (sphere diameter ≈ λ) through experimental measurements and computational modeling. In doing so, linkages between single‐scattering and multiple‐scattering effects of polarized light are investigated to gain mechanistic insight into the question of why linear DOP is often greater than circular DOP when light is backscattered from turbid media comprised of Rayleigh‐regime scatterers – a phenomenon which is not yet well understood. The findings of the study may indicate that linear DOP is enhanced by Rayleigh scatterers due to 1) increased direct backscattering pathways (via mirror‐like large‐angle reflections from scatterers) and 2) increased arc‐like‐pathway scattering along the plane that is perpendicular to the incident linear polarization vector. Both 1) and 2) result in higher co‐linear intensity, also resulting in overall higher linear DOP than circular DOP.

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
