A tree topology, or star-bus topology, is a hybrid network topology in which star networks are interconnected via bus networks. [ 1 ] [ 2 ] Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.
A fat tree A 2-level fat tree with 8-port switches. The fat tree network is a universal network for provably efficient communication. [1] It was invented by Charles E. Leiserson of the MIT in 1985. [1] k-ary n-trees, the type of fat-trees commonly used in most high-performance networks, were initially formalized in 1997. [2]
A hypertree network is a network topology that shares some traits with the binary tree network. [1] It is a variation of the fat tree architecture. [2]A hypertree of degree k depth d may be visualized as a 3-dimensional object whose front view is the top-down complete k-ary tree of depth d and the side view is the bottom-up complete binary tree of depth d.
Although some methods produce unrooted networks that can be interpreted as undirected versions of rooted networks, which do represent a phylogeny. Rooted phylogenetic network Let X be a set of taxa. A rooted phylogenetic network N on X is a rooted directed acyclic graph where the set of leaves is bijectively labeled by the taxa in X.

[1] [2] SplitsTree implements published methods such as split decomposition, [3] neighbor-net, consensus networks, [4] super networks methods or methods for computing hybridization or simple recombination networks. It uses the NEXUS file format. The splits graph is defined using a special data block (SPLITS block).
The countries in which the French Wikipedia is the most popular language version of Wikipedia are shown in dark blue. Page views by country over time on the French Wikipedia. The audience measurement company Médiamétrie questioned a sample of 8,500 users residing in France with access to Internet at home or at their place of work.
Arbuscular mycorrhizal networks are those in which fungal hyphae not only enter the plant's roots but also penetrate into the cells themselves. Ectomycorrhizal networks send hyphae into the roots where they thread their way between the plant cells but do not penetrate cell walls. The arbuscular type is the most common among land plants and is ...
