Squared distance matrix of a weighted tree [PDF]
Let T be a tree with vertex set {1, …, n} such that each edge is assigned a nonzero weight. The squared distance matrix of T, denoted by Δ, is the n × n matrix with (i, j)-element d(i, j)2, where d(i, j) is the sum of the weights of the edges on the ...

A unified approach to protein domain parsing with inter-residue distance matrix. [PDF]
Motivation It is fundamental to cut multi-domain proteins into individual domains, for precise domain-based structural and functional studies. In the past, sequence-based and structure-based domain parsing was carried out independently with different ...

Entropy measures of distance matrix [PDF]
Bonchev and Trinajstic defined two distance based entropy measures to measure the molecular branching of molecular graphs in 1977 [Information theory, distance matrix, and molecular branching, J. Chem. Phys., 38 (1977), 4517–4533]. In this paper we use these entropy measures which are based on distance matrices of graphs.

Eigenvalues of the resistance-distance matrix of complete multipartite graphs. [PDF]
Let G=(V,E)$G=(V, E)$ be a simple graph. The resistance distance between i,j∈V$i,j\in V$, denoted by rij$r_{ij}$, is defined as the net effective resistance between nodes i and j in the corresponding electrical network constructed from G by replacing ...

FastTree: Computing Large Minimum Evolution Trees with Profiles instead of a Distance Matrix
Gene families are growing rapidly, but standard methods for inferring phylogenies do not scale to alignments with over 10,000 sequences. We present FastTree, a method for constructing large phylogenies and for estimating their reliability.
