Nodes having a major influence to break cooperation define a novel centrality measure: game centrality. [PDF]
PLoS ONE, 2013 Cooperation played a significant role in the self-organization and evolution of living organisms. Both network topology and the initial position of cooperators heavily affect the cooperation of social dilemma games.

An Analysis of Centrality’s Features as a New Measure for Network Analysis, Risk Measurement & Portfolio Selection [PDF]
تحقیقات مالی, 2021 Objective: In network theory, centrality is a measure to estimate importance and influence of a special node to the whole network structure. The aim of this research is to investigate the characteristics of stock centrality and its reliability in risk ...

X-index: A novel flow-based locational measure for quantifying centrality
International Journal of Applied Earth Observations and Geoinformation, 2023 The centrality of a place reflects its relative importance in serving other places, and quantifying centrality is a prerequisite for assessing the urban spatial structure and facilitates policy-making of sustainable urban development.

Scale-dependent measure of network centrality from diffusion dynamics
Physical Review Research, 2020 Classic measures of graph centrality capture distinct aspects of node importance, from the local (e.g., degree) to the global (e.g., closeness). Here we exploit the connection between diffusion and geometry to introduce a multiscale centrality measure. A

A measure of centrality in cyclic diffusion processes: Walk-betweenness.
PLoS ONE, 2021 Unlike many traditional measures of centrality based on paths that do not allow any repeated nodes or lines, we propose a new measure of centrality based on walks, walk-betweenness, that allows any number of repeated nodes or lines.

Functional centrality in graphs [PDF]
, 2006 In this paper we introduce the functional centrality as a generalization of the subgraph centrality. We propose a general method for characterizing nodes in the graph according to the number of closed walks starting and ending at the node.

A study of the stability of information and telecommunication networks under conditions of stochastic percolation of nodes [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2021 In-depth studies of the topological properties of information and telecommunication networks contribute to the understanding of their functional capabilities, including stability.

Flowthrough Centrality: A Stable Node Centrality Measure
Journal of Data Science, 2022 This paper introduces flowthrough centrality, a node centrality measure determined from the hierarchical maximum concurrent flow problem (HMCFP). Based upon the extent to which a node is acting as a hub within a network, this centrality measure is defined to be the fraction of the flow passing through the node to the total flow capacity of the node ...

A Time-Ordered Aggregation Model-Based Centrality Metric for Mobile Social Networks
IEEE Access, 2018 How to measure the centrality of nodes is a significant problem in mobile social networks (MSNs). Current studies in MSNs mainly focus on measuring the centrality of nodes in a certain time interval based on the static graph that do not change over time.

Measuring node centrality when local and global measures overlap
Physical Review E, 2022 Centrality metrics aim to identify the most relevant nodes in a network. In literature, a broad set of metrics exists, either measuring local or global centrality characteristics. Nevertheless, when networks exhibit a high spectral gap, the usual global centrality measures typically do not add significant information with respect to the degree, i.e ...
