In particular, agents acquire different roles with respect to communication, with a core of tightly connected agents and hubs, and a large periphery.
This is particularly important in the study of collective phenomena like protest coordination via social media: these communication networks tend to be large and complex, with distinct local affiliations, a small core of highly active actors, and a large periphery of lowly committed users [13] [16].
Secondly, orchid bees use only one core area extensively but have an extremely large periphery which they visit to gather rare resources, such as floral fragrances.
Compared to SCE, clusters have on average about the same size, but a slightly smaller core and a slightly larger periphery (recall that a periphery vertex may occur in more than one cluster).
The centres that participated are different centres: academic, nonacademic, large periphery hospitals, and a specialized cancer centre.
The global reduction of average degree is driven by the average degree reduction in the large periphery of the network.
One of the biggest problems, Rios says, is the tendency to lump all gang members together, when, in truth, there are two things going on: a tiny nucleus committing extreme acts of violence, and a much larger periphery that's just trying to fit in kids like Jenny.

Note that when comparing the number of detected complexes, then SCE is at a disadvantage, since it can use each protein as periphery only once, while having large peripheries makes it easier to count a complex as detected.
The main result was that the individual categories always presented a core of certainty where judgment was totally consistent, and large peripheries where judgment was inconsistent.
Therefore, a large volume at the periphery of the lung will not contribute to separating the healthy and COPD distributions.
