Abstract

fetched live from OpenAlex

Two series of mesogenic molecules have been simulated using molecular dynamics with a full atomistic representation. The two series differ from each other only with the orientation of an ester linker inside the rigid core. Experimentally, this small difference leads to drastically different polymorphisms: one displays the smectic A phase while the other exhibits the smectic C and the smectic A phase. From molecular dynamics trajectories, intermolecular potentials are extracted and analyzed. It is then found that the minor difference inside the rigid core can be related to these various interactions. Finally, experimental and simulation results are integrated in a coherent analysis. The correlation between both types of data offers interesting insights in the role of the Coulomb and van der Waals interactions in the molecular origin of the smectic C phase.

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.
