Vertex-Edge-Degree-Based Topological Properties for Hex-Derived Networks
Complexity, 2022 A topological index can be focused on uprising of a chemical structure into a real number. The degree-based topological indices have an active place among all topological indices.

Topological Descriptors of M-Carbon Mr,s,t
Journal of Chemistry, 2021 We have studied topological indices of the one the hardest crystal structures in a given chemical system, namely, M-carbon. These structures are based and obtained by the famous algorithm USPEX. The computations and applications of topological indices in

From Trees to Barcodes and Back Again: Theoretical and Statistical Perspectives
Algorithms, 2020 Methods of topological data analysis have been successfully applied in a wide range of fields to provide useful summaries of the structure of complex data sets in terms of topological descriptors, such as persistence diagrams.

Multiplicative topological descriptors of Silicon carbide [PDF]
Applied Mathematics and Nonlinear Sciences, 2019 Abstract Topological indices helps us to collect information about algebraic graphs and gives us mathematical approach to understand the properties of chemical structures. In this paper, we aim to compute multiplicative degree-based topological indices of Silicon-Carbon Si 2

Chemical applicability of Sombor indices [PDF]
Journal of the Serbian Chemical Society, 2021 Recently, a novel class of degree-based topological molecular descriptors was proposed, the so-called Sombor indices. Within this study, the predictive and discriminative potentials of the Sombor index, the reduced Sombor index, and the average Sombor ...

TCDesc: Learning Topology Consistent Descriptors
CoRR, 2020 Triplet loss is widely used for learning local descriptors from image patch. However, triplet loss only minimizes the Euclidean distance between matching descriptors and maximizes that between the non-matching descriptors, which neglects the topology similarity between two descriptor sets.
