Abstract: This article addresses the problem of multiagent communication in networks with a regular directed ring structure. These can be viewed as hierarchical extensions of the classical cyclic ...

The words drifted down the path and over the wooden bridge, accompanied by the thud of running shoes hitting the dirt: “So what did the C-13 show?” The two runners were past me before I could catch ...

Topological matter refers to systems in which topology is required for their characterisation. This includes materials with topological defects such as skyrmions, or topologically-protected edge modes ...
