Sun, P. (author), Kooij, Robert (author), Van Mieghem, P.F.A. (author)In this paper, we propose closed-form analytic approximations for the number of controllable nodes in sparse communication networks from the aspect of network controllability, considering link-based random attack, targeted attack, as well as random attack under the protection of critical links. We compare our approximations with simulation...journal article 2021

(author), Hillebrand, Arjan (author), Daffertshofer, Andreas (author), Coombes, Stephen (author), Van Mieghem, P.F.A. (author)Large-scale neurophysiological networks are often reconstructed from band-pass filtered time series derived from magnetoencephalography (MEG) data. Common practice is to reconstruct these networks separately for different frequency bands and to treat them independently. Recent evidence suggests that this separation may be inadequate, as there...journal article 2021

This paper proposes an approach on network modeling and robustness assessment for multimodal freight transport networks, where the nodes represent junctions, terminals and crossings, and the links represent...journal article 2021

(author), Idema, Sander (author), Baayen, Johannes C. (author), Velis, Demetrios (author), Van Mieghem, P.F.A. (author), Hillebrand, Arjan (author)The success of epilepsy surgery in patients with refractory epilepsy depends upon correct identification of the epileptogenic zone (EZ) and an optimal choice of the resection area. In this study we developed individualized computational models based upon structural brain networks to explore the impact of different virtual resections on the...journal article 2021

Prasse, B. (author), Devriendt, K.L.T. (author), Van Mieghem, P.F.A. (author)Infectious diseases typically spread over a contact network with millions of individuals, whose sheer size is a tremendous challenge to analyzing and controlling an epidemic outbreak. For some contact networks, it is possible to group individuals into clusters. A high-level description of the epidemic between a few clusters is considerably...journal article 2021

Van Mieghem, P.F.A. (author)The -susceptible-infected-susceptible (SIS) epidemic model on a graph adds an independent, Poisson self-infection process with rate to the "classical" Markovian SIS process. The steady state in the classical SIS process (with =0) on any finite graph is the absorbing or overall-healthy state, in which the virus is eradicated from the network....journal article 2020

Pizzuti, Clara (author), Socievole, Annalisa (author), Prasse, B. (author), Van Mieghem, P.F.A. (author)Initially emerged in the Chinese city Wuhan and subsequently spread almost worldwide causing a pandemic, the SARS-CoV-2 virus follows reasonably well the Susceptible–Infectious–Recovered (SIR) epidemic model on contact networks in the Chinese case. In this paper, we investigate the prediction accuracy of the SIR model on networks also for...journal article 2020

(author)We study the electrodynamic impedance of percolating conductors with a predefined network topology using a scanning microwave impedance microscope at gigahertz frequencies. For a given percolation number we observe strong spatial variations across a sample that correlate with the connected regions (clusters) in the network when the...journal article 2020

Time dependence of susceptible-infected-susceptible epidemics on networks with nodal self-infectionsVan Mieghem, P.F.A. (author), Wang, F. (author)The average fraction of infected nodes, in short the prevalence, of the Markovian ɛ-SIS (susceptible-infected-susceptible) process with small self-infection rate ɛ>0 exhibits, as a function of time, a typical "two-plateau" behavior, which was first discovered in the complete graph KN. Although the complete graph is often dismissed as an...journal article 2020

Achterberg, M.A. (author), Dubbeldam, J.L.A. (author), Van Mieghem, P.F.A. (author), Stam, Cornelis J. (author)In the classical susceptible-infected-susceptible (SIS) model, a disease or infection spreads over a given, mostly fixed graph. However, in many real complex networks, the topology of the underlying graph can change due to the influence of the dynamical process. In this paper, besides the spreading process, the network adaptively changes its...journal article 2020

Prasse, B. (author), Achterberg, M.A. (author), Ma, L. (author), Van Mieghem, P.F.A. (author)At the moment of writing, the future evolution of the COVID-19 epidemic is unclear. Predictions of the further course of the epidemic are decisive to deploy targeted disease control measures. We consider a network-based model to describe the COVID-19 epidemic in the Hubei province. The network is composed of the cities in Hubei and their...journal article 2020

(author), Van Mieghem, P.F.A. (author), Hillebrand, Arjan (author)Functional brain networks are shaped and constrained by the underlying structural network. However, functional networks are not merely a one-to-one reflection of the structural network. Several theories have been put forward to understand the relationship between structural and functional networks. However, it remains unclear how these...journal article 2020

Prasse, B. (author), Van Mieghem, P.F.A. (author)The majority of epidemic models are described by non-linear differential equations which do not have a closed-form solution. Due to the absence of a closed-form solution, the understanding of the precise dynamics of a virus is rather limited. We solve the differential equations of the N-intertwined mean-field approximation of the susceptible...journal article 2020

Devriendt, Karel (author), Van Mieghem, P.F.A. (author)Graphs are a central object of study in various scientific fields, such as discrete mathematics, theoretical computer science and network science. These graphs are typically studied using combinatorial, algebraic or probabilistic methods, each of which highlights the properties of graphs in a uniqueway. Here, we discuss a novel approach to study...review 2019

Sun, P. (author), Van Mieghem, P.F.A. (author), Kooij, Robert (author), He, Z. (author), Van Mieghem, Piet (author)In this paper, we propose closed-form analytic approximations for the minimum number of driver nodes needed to fully control networks, where links are removed according to both random and targeted attacks. Our approximations rely on the concept of critical links. A link is called critical if its removal increases the required number of driver...conference paper 2019

Çetinay Iyicil, H. (author), Koc, Y. (author), Kuipers, F.A. (author), Van Mieghem, P.F.A. (author)Direct connections between nodes usually result in efficient transmission in networks. Such electric power transmission is governed by physical laws, and an assessment purely based on direct connections between nodes and shortest paths may not capture the operation of power grids. Motivated by these facts, in this chapter, we investigate the...book chapter 2019

Prasse, B. (author), Van Mieghem, P.F.A. (author)The majority of research on epidemics relies on models which are formulated in continuous-time. However, processing real-world epidemic data and simulating epidemics is done digitally and the continuous-time epidemic models are usually approximated by discrete-time models. In general, there is no guarantee that properties of continuous-time...journal article 2019

This paper proposes a general topological approach and recoverability indicators to measure the network recoverability in two scenarios: 1) recovery of damaged connections and 2) any...conference paper 2019

Wang, X. (author), Kooij, Robert (author), Moreno, Yamir (author), Van Mieghem, P.F.A. (author)Networks are often made up of several layers that exhibit diverse degrees of interdependencies. An interdependent network consists of a set of graphs G that are interconnected through a weighted interconnection matrix B, where the weight of each intergraph link is a non-negative real number p. Various dynamical processes, such as...journal article 2019

Ma, L. (author), Liu, Q. (author), Van Mieghem, P.F.A. (author)Dynamical processes running on different networks behave differently, which makes the reconstruction of the underlying network from dynamical observations possible. However, to what level of detail the network properties can be determined from incomplete measurements of the dynamical process is still an open question. In this paper, we focus on...journal article 2019
