Graph Residual Flow for Molecular Graph Generation

open access: yesCoRR, 2019
Statistical generative models for molecular graphs attract attention from many researchers from the fields of bio- and chemo-informatics. Among these models, invertible flow-based approaches are not fully explored yet. In this paper, we propose a powerful invertible flow for molecular graphs, called graph residual flow (GRF).

Computing Edge Metric Dimension of One-Pentagonal Carbon Nanocone

open access: yesFrontiers in Physics, 2021
Minimum resolving sets (edge or vertex) have become an integral part of molecular topology and combinatorial chemistry. Resolving sets for a specific network provide crucial information required for the identification of each item contained in the ...

Comparing energy and Randic energy

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2013
The recently conceived Randić energy (RE) is examined, and its relation to the (earlier much studied) total π-electron energy (E) is investigated. Within classes of molecular graphs, there exists a relatively good (increasing) linear correlation between ...

Computing entire Zagreb indices of some dendrimer structures

open access: yesMain Group Metal Chemistry, 2020
Topological indices are numerical numbers associated to molecular graphs and are invariant of a graph. In QSAR/QSPR study, Zagreb indices are used to explain the different properties of chemical compounds at the molecular level mathematically.

Graph Transformation in Molecular Biology [PDF]

open access: yes, 2005
In the beginning, one of the main fields of application of graph transformation was biology, and more specifically morphology. Later, however, it was like if the biological applications had been left aside by the graph transformation community, just to be moved back into the mainstream these very last years with a new interest in molecular biology.

Graph-based implicit knowledge discovery from architecture change logs [PDF]

open access: yes, 2012
Service architectures continuously evolve as a consequence of frequent business and technical change cycles. Architecture change log data represents a source of evolution-centric information in terms of intent, scope and operationalisation to ...

Total Semirelib Graph [PDF]

open access: yes, 2013
In this paper, the concept of Total semirelib graph of a planar graph is introduced. Authors present a characterization of those graphs whose total semirelib graphs are planar, outer planar, Eulerian, hamiltonian with crossing number ...

Entropy comparison of benzothiadiazole-based covalent-organic frameworks

open access: yesFrontiers in Chemistry
Covalent Organic Frameworks (COFs) are popular photocatalysts that utilize solar energy to generate hydrogen peroxide and evolve hydrogen because of their intrinsic porosity, robust framework, and excellent structural regularity.

Computing the Ediz eccentric connectivity index of discrete dynamic structures

open access: yesOpen Physics, 2017
From the earlier studies in physical and chemical sciences, it is found that the physico-chemical characteristics of chemical compounds are internally connected with their molecular structures. As a theoretical basis, it provides a new way of thinking by
