| Carbon nanotubes are conductors or semiconductors, based on coiling helicity. |
| As a result of the weak interaction, each helicity state propagates with a different phase so that the transverse polarization vector rotates. |
| When tornadoes occur, however, it has been noted that they are generally accompanied by helicity values above a certain threshold. |
| Consequently, helicity is an indicator of the presence of tornadoes in an environment where severe thunderstorms are forecast. |
| This reduced its helicity and increased its average tilt, thereby presumably reducing fusion efficiency. |
| One peptide was designed to maximize helicity and the other, having the same composition but a different sequence, was designed to minimize helical formation. |
