Fluctuations in Network Dynamics [PDF]
Physical Review Letters, 2004 Most complex networks serve as conduits for various dynamical processes, ranging from mass transfer by chemical reactions in the cell to packet transfer on the Internet. We collected data on the time dependent activity of five natural and technological networks, finding that for each the coupling of the flux fluctuations with the total flux on ...

Physics Reports, 2023 It is a fundamental challenge to understand how the function of a network is related to its structural organization. Adaptive dynamical networks represent a broad class of systems that can change their connectivity over time depending on their dynamical state.

hybridModels: An R Package for the Stochastic Simulation of Disease Spreading in Dynamic Networks
Journal of Statistical Software, 2020 Disease spreading simulations are traditionally performed using coupled differential equations. However, in the setting of metapopulations, most of the solutions provided by this method do not account for the dynamic topography of subpopulations ...

Influential Performance of Nodes Identified by Relative Entropy in Dynamic Networks
Vietnam Journal of Computer Science, 2021 For decades, centrality has been one of the most studied concepts in the case of complex networks. It addresses the problem of identification of the most influential nodes in the network.

Identifiability and transportability in dynamic causal networks [PDF]
, 2016 In this paper we propose a causal analog to the purely observational Dynamic Bayesian Networks, which we call Dynamic Causal Networks. We provide a sound and complete algorithm for identification of Dynamic Causal Networks, namely, for computing the ...

Frontiers in Sociology, 2022 The ongoing COVID-19 pandemic constitutes a critical phase for the transnationalization of public spheres. Against this backdrop, we ask how transnational COVID-19 related online discourse has been throughout the EU over the first year of the pandemic ...

Mathematical Biosciences and Engineering, 2022 Mathematical modeling of epidemic diseases is increasingly being used to respond to emerging diseases. Although conditions modeled by SIS dynamics will eventually reach either a disease-free steady-state or an endemic steady state without interventions ...

Optimal change point detection and localization in sparse dynamic networks [PDF]
Annals of Statistics, 2018 We study the problem of change point detection and localization in dynamic networks. We assume that we observe a sequence of independent adjacency matrices of given size, each corresponding to one realization from an unknown inhomogeneous Bernoulli model.

Tracking the Evolution of Communities in a Social Network of Intellectual Influences
Journal of Historical Network Research, 2022 The history of intellectuals consists of a long spanning entangled web of influences, interdependencies, and inspirations. In this paper, we con- strue the history of intellectuals with the means of a formalized network approach, and analyze ...

Frontiers in Computational Neuroscience, 2018 In spike-timing dependent plasticity (STDP) change in synaptic strength depends on the timing of pre- vs. postsynaptic spiking activity. Since STDP is in compliance with Hebb’s postulate, it is considered one of the major mechanisms of memory storage and
