Abstract

fetched live from OpenAlex

The template effect in the formation of a trimer carceplex using 1-3 molecules as templates is explored. Thirteen different templates were studied and template ratios were measured for templates of like and unlike molecularity. Five transition-state models were studied for their binding abilities to see if these mirror the template ratios. The chemical shifts of the guests and the thermodynamic and kinetic values for templation suggest that binding is key, often tight, and that the guest determining step is formation of the last covalent bond. The molecular dynamics of guests as well as the conformational dynamics of both hosts and guests further addresses nature of the recognition between host and guest. Finally, we were surprised to discover that water can bind reversibly to the trimer carceplexes, which will have ramifications to any inner phase reactions conducted inside the cage.

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.

Not 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.
