Relation between diffusion constant and particle density in TiO 2 suspended solutions
Bibliographic record
Abstract
We present time-resolved measurements of pulse transmission at wavelength 532 nm (60 ps pulse width, 10 Hz repetition rate) on samples of titanium powders suspended in methanol. The average particle diameter of the powders is 80 nm. We used a streak camera with 2 ps time revolution to record the transmitted signals. When the particle density is low, the results agreed with the diffusion theory and we obtained the time-independent diffusion constants. By adding the titanium powders gradually in methanol, we obtained the relationship between the diffusion constant and the particle density of TiO<sub>2</sub> in the suspended solution. When using the TiO<sub>2</sub> powders as the sample with a particle density of 1.36x10<sup>15</sup> cm<sup>-3</sup>, the experimental result showed a little deviation from the diffusion theory, which may be the signature of localization in the random media.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
