Tree of hubs location problem (THLP): Another related problem with a tree-star topology is the tree of hubs location problem proposed by Contreras et al. [11].
The architecture of the MN is scale-free, where hub trees are highly connected relative to other trees in the forest (Beiler et al. 2010), and this is characteristic of a complex adaptive system (Simard et al. 2013; Beiler et al. 2015).
Targeted loss of hub trees, however, can cross thresholds that destabilize ecosystems.
Considering the special role of hubs in a scale-free network, Cho and Zhang restructured a complex interactome network into a hub-oriented hierarchical tree based on the path strength model, and then identified structural hubs and functional modules on the basis of hub confidence scores [ 6].
Fonolo, a startup that won the top prize at today's GigaOM Mobilize Conference, provides users not only with a way to bypass the irritating and inefficient trees, but also a central hub to help monitor previous conversations for future reference.
This park is divided into about six lands around one central hub area/monument called The Tree of Life.
In one video clip from 2011, Khorasan fighters are seen searching traffic under a cluster of palm trees outside Mir Ali, a notorious militant hub.
Across the road is Portcullis House, a modern office block whose tree-lined atrium is increasingly the hub of Westminster life; the place to see and be seen.
LULEA, SWEDEN — At the edge of this small northern city, in a thicket of trees and hardened snow, a future hub of Facebook's global data traffic is taking shape.
The social hub is a central tree-lined street where people stroll back and forth, saying hello to one another umpteen times a day.
The island's main hub, Horseshoe Bay, with its palm trees, clear blue water and gentle lapping waves, is a great spot to swim or just sip beer while watching the sun disappear into the sea.
