Distance-Based Topological Descriptors on Ternary Hypertree Networks
Complexity, 2022 Topological indices are numeric parameters which portray the topology of a subatomic structure. In QSAR/QSPR analysis, topological descriptors play a vital role to examine the topology of a network.

Topological Descriptors of Histology Images [PDF]
, 2014 The purpose of this study is to investigate architectural characteristics of cell arrangements in breast cancer histology images. We propose the use of topological data analysis to summarize the geometric information inherent in tumor cell arrangements.

Topological localization using optical flow descriptors
2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011 We propose a topological localization method based on optical flow information. We analyse the statistical characteristics of the optical flow signal and demonstrate that the flow vectors can be used to identify and describe key locations in the environment.

Novel Degree-Based Topological Descriptors of Carbon Nanotubes
Journal of Chemistry, 2021 The most significant tool of mathematical chemistry is the numerical descriptor called topological index. Topological indices are extensively used in modelling of chemical compounds to analyse the studies on quantitative structure activity/property ...

On Topological Descriptors of Certain Metal-Organic Frameworks
Journal of Chemistry, 2020 Topological indices are numerical numbers that represent the topology of a molecule and are calculated from the graphical depiction of the molecule. The importance of topological indices is due to their use as descriptors in QSPR/QSAR modeling.

GTI-space : the space of generalized topological indices [PDF]
, 2008 A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

How the parts organize in the whole : a top-downview of molecular descriptors and properties for QSARand drug design [PDF]
, 2008 Sometimes the complexity of a system, or the properties derived from it, do depend neither on the individual characteristics of the components of the system nor on the nature of the physical forces that hold them together.

Topological Sholl descriptors for neuronal clustering and classification [PDF]
PLOS Computational Biology, 2021 Neuronal morphology is a fundamental factor influencing information processing within neurons and networks. Dendritic morphology in particular can widely vary among cell classes, brain regions, and animal species. Thus, accurate quantitative descriptions allowing classification of large sets of neurons is essential for their ...

Inequalities Among Topological Descriptors
Kragujevac Journal of Mathematics, 2023 A topological index is a type of molecular descriptor that is calculated based on the molecular graph of a chemical compound. Topological indices are used for example in the development of QSAR QSPR in which the biological activity or other properties of molecules are correlated with their chemical structure.
