Abstract

fetched live from OpenAlex

Abstract We present the first experiments on electrohydrodynamic convection with a superposed Couette shear in freely suspended annular smectic C* films. Similar experiments on smectic A films have been carried out previously. In those experiments, surface-charge driven electro-convection in combination with shear leads to a pattern of travelling convective vortices. Travelling vortex patterns are also observed in smectic C* films. In contrast to smectic A films, however, the flow field in C* films is coupled to c-director orientation effects that allow a direct visualization of the periodic flow pattern. The critical voltage for the onset of convection was determined by electric current measurements and compared with corresponding results for smectic A films. Measurements at various shear rates show that the onset is suppressed by the shear.

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.
