1. Sexual size dimorphism (SSD) is a common phenomenon in animals. Rensch's rule states that larger species generally exhibit a higher male to female body size ratio than smaller ones. 2. Domesticated animals offer excellent opportunities for testing predictions of the functional explanations of Rensch's rule and this was tested in a meta-analysis of SSD in 38 breeds of domestic geese compared ...

Flexoelectricity, in which a dielectric material develops an electrical polarization response to mechanical strain, is important degree of freedom for designing actuators with simpler structure and higher performance. Its applications are usually limited the nanoscale, though, due phenomenon's inherent size dependence. This study presents $i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}v\phant...
