Abstract

fetched live from OpenAlex

Polarization characteristics and spectra of photoluminescence in CdSe nanorods suspended in liquid were investigated. Experiments demonstrated the presence of the polarization memory related to the mismatch of nanorods and solvent dielectric constants, as well as to anisotropy of optical matrix elements. Luminescent spectra contained two peaks corresponding to interband transitions between the ground and excited size-quantized states and having essentially different values of polarization memory, presumably due to different anisotropy of corresponding matrix elements. The amplitude of polarization memory decreased with the increase in concentration of nanorods confirming the hypothesis of their mutual influence.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
