ring-shaped

The ring-shaped laser beam played a key role in this breakthrough -- as did critical "in-situ" experiments, says Jiandong Yuan, the lead author of the paper and a PhD student in Chen's group.

The connectors bonded to specific sites on the poles, creating a sheet with ring-shaped voids, a bit like a chain-link fence.

Serra's predictions suggested that with a particular distribution of myosin, they could make a ring-shaped short-time attractor.

The emitters create 3D acoustic vortex fields that can pass through barriers such as bone and tissue, crossing over one another to form tiny ring-shaped acoustic traps.

Light can also help heat the plasma within ring-shaped devices known as tokamaks as scientists worldwide strive to harness the fusion process to generate green electricity.
