Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

Symmetry detection represents a cornerstone in computer vision, fundamentally enhancing object recognition, reconstruction, and classification. Its significance lies in the capacity to identify ...

After identifying interlocking symmetries in mammalian cells, scientists can describe some tissues as liquid crystals — an observation that lays the groundwork for a fluid-dynamic theory of how ...
