title: Thermomechanical oscillations in hybrid nematic liquid crystals.
abstract: Thermomechanical oscillations observed previously in hybrid oriented nematic liquid crystals (NLCs) are explained theoretically. The effect is conditioned by the hydrodynamic flow tendency to reduce the curvature of the "flexible ribbon" of hybrid NLCs. There is qualitative agreement between the theoretical calculations and the experimental results.
