symmetric

All participants were tested for distal symmetric polyneuropathy.

"The key turned out to be structural instabilities that result in certain atoms, in this case the Ti atoms, to displace away from more symmetric positions in a disordered manner. Small anisotropic displacements showed up in high-resolution synchrotron experiments, then we knew to look closer at the atomic structure using an electron microscope."

In the end, "it turned out that yes, you can actually valley polarize bulk materials that are central symmetric, because of the symmetry conditions," concludes Poborska.

This body-first pathway is often associated with Lewy body dementia, a disease in the same family as Parkinson's, which is characterized by early constipation and sleep disturbance, followed by more symmetric slowing in movements and earlier dementia, as the disease spreads through both brain hemispheres.

While the head is generally radially symmetric -- it can be divided into two equal halves in multiple directions like a starfish or a pie -- the individual flowers can have different forms of symmetry.
