Linking the network centrality measures closeness and degree

TS Evans, B Chen - Communications Physics, 2022 - nature.com
Measuring the importance of nodes in a network with a centrality measure is an core task in
any network application. There many measures available and it is speculated that many …

Exploring scientific trajectories of a large-scale dataset using topic-integrated path extraction

EHJ Kim, YK Jeong, YH Kim, M Song - Journal of Informetrics, 2022 - Elsevier
Main path analysis (MPA) is the most widely accepted approach to tracing knowledge
transfer in a research field. In this study, we extracted multiple longest paths from the …

[HTML][HTML] Power laws, the Price model, and the Pareto type-2 distribution

G Siudem, P Nowak, M Gagolewski - Physica A: Statistical Mechanics and …, 2022 - Elsevier
We consider a version of D. Price's model for the growth of a bibliographic network, where in
each iteration, a constant number of citations is randomly allocated according to a weighted …

[HTML][HTML] Cycle analysis of directed acyclic graphs

V Vasiliauskaite, TS Evans, P Expert - Physica A: Statistical Mechanics and …, 2022 - Elsevier
In this paper, we employ the decomposition of a directed network as an undirected graph
plus its associated node meta-data to characterise the cyclic structure found in directed …

Making communities show respect for order

V Vasiliauskaite, TS Evans - Applied Network Science, 2020 - Springer
In this work we give a community detection algorithm in which the communities both
respects the intrinsic order of a directed acyclic graph and also finds similar nodes. We take …

PGJ Persoon - 2021 - research.tue.nl
Mitigating global climate change requires, amongst other measures, the replacement of
Fossil Fuel based Energy Technologies (FFETs) by Renewable Energy Technologies …

Developing an evaluation framework for screen doors on railway platforms

UT Abdurrahman - 2021 - etheses.bham.ac.uk
Platform Screen Doors (PSDs) are physical barriers installed at the edges of platforms in
train stations. Such doors are widely used in modern metro stations and some heavy rail …

Cumulative structure and path length in networks of knowledge

PGJ Persoon - arXiv preprint arXiv:2106.10480, 2021 - arxiv.org
An important knowledge dimension of science and technology is the extent to which their
development is cumulative, that is, the extent to which later findings build on earlier ones …

Growth of Random Trees by Leaf Attachment

N Sibisi - arXiv preprint arXiv:2010.05589, 2020 - arxiv.org
We study the growth of a time-ordered rooted tree by probabilistic attachment of new vertices
to leaves. We construct a likelihood function of the leaves based on the connectivity of the …

Fundamental complexity and networks

T Links, UO Days - imperial.ac.uk
In the Centre for Complexity Science, we study a range of different systems to find general
principles behind the dynamics and the emergent structures we see. We use concepts and …
