Leveraging Different Distance Functions to Predict Antiviral Peptides with Geometric Deep Learning from ESMFold-Predicted Tertiary Structures [PDF]

open access: yesAntibiotics
Background: Machine learning models have been shown to be a time-saving and cost-effective tool for peptide-based drug discovery. In this regard, different graph learning-driven frameworks have been introduced to exploit graph representations derived ...

On Eccentricity Version of Zagreb Coindices [PDF]

open access: yesMathematics Interdisciplinary Research, 2021
The eccentric connectivity coindex has recently been introduced (Hua and Miao, 2019) as the total eccentricity sum of all pairs of non-adjacent vertices in a graph.

Szeged-type indices of subdivision vertex-edge join (SVE-join)

open access: yesMain Group Metal Chemistry, 2021
In this article, we compute the vertex Padmakar-Ivan (PIv) index, vertex Szeged (Szv) index, edge Padmakar-Ivan (PIe) index, edge Szeged (Sze) index, weighted vertex Padmakar-Ivan (wPIv) index, and weighted vertex Szeged (wSzv) index of a graph product ...

A Quasi-Hole Detection Algorithm for Recognizing k-Distance-Hereditary Graphs, with k < 2

open access: yesAlgorithms, 2021
Cicerone and Di Stefano defined and studied the class of k-distance-hereditary graphs, i.e., graphs where the distance in each connected induced subgraph is at most k times the distance in the whole graph. The defined graphs represent a generalization of

The Generalized Distance Spectrum of the Join of Graphs [PDF]

open access: yes, 2020
Let G be a simple connected graph. In this paper, we study the spectral properties of the generalized distance matrix of graphs, the convex combination of the symmetric distance matrix D(G) and diagonal matrix of the vertex transmissions Tr(G) .

Status connectivity indices and co-indices of graphs and its computation to some distance-balanced graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The status of a vertex , denoted by , is the sum of the distances between and all other vertices in a graph . The first and second status connectivity indices of a graph are defined as and respectively, where denotes the edge set of .

The Threshold Dimension and Irreducible Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2023
Let G be a graph, and let u, v, and w be vertices of G. If the distance between u and w does not equal the distance between v and w, then w is said to resolve u and v.

Weiner Polynomials to Generalize the Distance of Some Composite Graphs from Special Graphs [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2008
It is not easy to find the Wiener polynomials for generalized distance of  compound graphs constructed in the form and  for any two disjoint connected graphs and .Therefore, in this paper, we obtain Wiener polynomials for generalized distance of and ...

Dualizing Distance-Hereditary Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Distance-hereditary graphs can be characterized by every cycle of length at least 5 having crossing chords. This makes distance-hereditary graphs susceptible to dualizing, using the common extension of geometric face/vertex planar graph duality to cycle ...
