Modeling the Zinc Chelating Rosette Nanotube
Bibliographic record
Abstract
Hybrid Guanine/Cytosine (G/spl and/C) is a well-established motif that forms nanotubular architectures via self-assembly process. Six G/C motifs form the rosette through hydrogen bonding and the rosettes stack on top of each other through /spl pi/ interaction to form the nanotubes. The chemo-physical properties of the tube are featured by the arrangement of the substituents on the G/C motifs. A zinc chelating pyridyl group attached to G/C motif has been synthesized and the metallated compound showed linearly aggregated bundles of nanotubes. Extensive molecular modeling work using molecular orbital theory at the PM5 semi-empirical level has been performed on the motif. It is found that nanotubes of the 3-pyridyl substituted G/spl and/C motif traps zinc ions between the pyridyl groups of two adjacent rosettes of a single tube. A model has been suggested to explain the linear aggregation of the nanotubes.

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.
