Processing of Nonlinear Optical Polymer Systems under Microgravity Conditions
Bibliographic record
Abstract
We report here the results of our microgravity experiments which were carried out at the ZARM drop tower facility at Bremen, Germany. Two systems were tested: (a) guest-host system using thermal processing and (b) cross-linked system using photocross-linking processing. Five drops of 4.75 sec of microgravity were made and for each drop 15 guest-host samples and 9 photo cross-linking samples were processed. The sample thickness was fixed at 2 μm, however poling field, UV intensity, chromophore type and concentration, poling temperature and cooling rate were varied. The relaxation behavior was monitored using second harmonic generation as a function of time for both the samples prepared at 10 -6 g and 1 g. Improvement of relaxation time was observed for certain samples. Simulations using a modified Robertson-Shimha-Curro (RSC) theory were also carried out. Qualitatively experimental results support the simulation hypothesis.
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
