Modified Heider Balance on Sparse Random Networks
R. Masoumi, F. Oloomi, S. Sajjadi +2
The lack of signed random networks in standard balance studies has prompted us to extend the Hamiltonian of the standard balance model. Random networks with tunable parameters are…
Heider Balance under Disordered Triadic Interactions
M. Bagherikalhor, A. Kargaran, A. H. Shirazi +1
The Heider balance addresses three-body interactions with the assumption that triads are equally important in the dynamics of the network. In many networks, the relations do not ha…
Stability of Imbalanced Triangles in Gene Regulatory Networks of Cancerous and Normal Cells
Abbas Karimi Rizi, Mina Zamani, Amirhossein Shirazi +2
Genes communicate with each other through different regulatory effects, which lead to the emergence of complex structures in cells, and such structures are expected to be different…
Mean-field solution of structural balance dynamics in nonzero temperature
F. Rabbani, Amir H. Shirazi, G. R. Jafari
In signed networks with simultaneous friendly and hostile interactions, there is a general tendency to a global structural balance, based on the dynamical model of links status. Al…
Ginzburg-Landau Theory of Dark Energy: A Framework to Study Both Temporal and Spatial Cosmological Tensions Simultaneously
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
A dark energy model (DE) is proposed based on Ginzburg-Landau theory of phase transition (GLT). This model, GLTofDE, surprisingly provides a framework to study not only temporal te…
Ups and Downs in Dark Energy: phase transition in dark sector as a proposal to lessen cosmological tensions
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
Based on tensions between the early and late time cosmology, we proposed a double valued cosmological constant which could undergo a phase transition in its history. It is named "d…
Non-criticality of interaction network over system's crises: A percolation analysis
Amir Hossein Shirazi, Abbas Ali Saberi, Ali Hosseiny +2
Extraction of interaction networks from multi-variate time-series is one of the topics of broad interest in complex systems. Although this method has a wide range of applications,…
Fractional Dynamics of Network Growth Constrained by aging Node Interactions
Hadiseh Safdari, Milad Zare Kamali, Amirhossein Shirazi +3
In many social complex systems, in which agents are linked by non-linear interactions, the history of events strongly influences the whole network dynamics. However, a class of "co…
The emergence of pseudo-stable states in network dynamics
L. Hedayatifar, F. Hassanibesheli, A. H. Shirazi +2
In the context of network dynamics, the complexity of systems increases possible evolutionary paths that often are not deterministic. Occasionally, some map routs form over the cou…
History effects on network growth
Hadiseh Safdari, Milad Zare Kamali, Amir Hossein Shirazi +2
Growth dynamic of real networks because of emerging complexities is an open and interesting question. Indeed it is not realistic to ignore history impact on the current events. The…
Transparency effect in the emergence of monopolies in social networks
A. H. Shirazi, A. Namaki, A. A. Roohi +1
Power law degree distribution was shown in many complex networks. However, in most real systems, deviation from power-law behavior is observed in social and economical networks and…
Coupling between time series: a network view
Saeed Mehraban, Amirhossein Shirazi, Maryam Zamani +1
Recently, the visibility graph has been introduced as a novel view for analyzing time series, which maps it to a complex network. In this paper, we introduce new algorithm of visib…
