A unified approach to protein domain parsing with inter-residue distance matrix. [PDF]

open access: yesBioinformatics, 2023
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]

open access: yesDiscrete Mathematics Letters, 2022
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.

Is Distance Matrix Enough for Geometric Deep Learning? [PDF]

open access: greenNeural Information Processing Systems, 2023
Graph Neural Networks (GNNs) are often used for tasks involving the 3D geometry of a given graph, such as molecular dynamics simulation. While incorporating Euclidean distance into Message Passing Neural Networks (referred to as Vanilla DisGNN) is a ...

Spectral properties of the exponential distance matrix [PDF]

open access: greenInvolve. A Journal of Mathematics, 2019
Given a graph $G$, the exponential distance matrix is defined entry-wise by letting the $(u,v)$-entry be $q^{\text{dist}(u,v)}$, where $\text{dist}(u,v)$ is the distance between the vertices $u$ and $v$ with the convention that if vertices are in ...

Eigenvalues of the resistance-distance matrix of complete multipartite graphs. [PDF]

open access: yesJ Inequal Appl, 2017
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 ...
