The Complex Systems and Networks Lab (COSNET) is part of the Institute for Biocomputation and Physics of Complex Systems (BIFI) of the University of Zaragoza, and is mainly devoted to investigate the laws governing the structure and dynamics of complex networked systems.
The group was constituted and introduced as one of BIFI’s research lines in 2003 by Dr. Yamir Moreno after returning from a postdoctoral stay at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. The main goal was to promote the scientific research in a promising subject with multiple applications to various scientific fields such as: synchronization phenomena, epidemic spreading, analysis of biological, economic and social systems, communication networks, etc. The group gradually took shape during the first years with the support and collaboration of other members of the Department of Condensed Matter and Theoretical Physics and grew up later to reach its actual status. Nowadays, the group has consolidated at BIFI and at the University of Zaragoza and has also the recognition of many researchers within and outside our borders. Currently, the line is one of the most prolific of our Institute according to the number of high-impact scientific publications in international journals and the projection of our group in the field of Complex Systems and Networks.
During all these years, our research has been aimed at uncovering the mechanisms behind diverse complex phenomena in various scientific fields. The work carried out includes several studies about synchronization processes, disease contagion, and the analysis of biological, economic and socio-technological systems. Lately, we have also focused our interest in Systems Biology of TB and the network approach to brain and cognitive sciences.

The Transcriptional Regulatory Network of Mycobacterium Tuberculosis
In this study, we present an updated version of the TR network of Mycobacterium tuberculosis (M.tb), which incorporates newly characterized transcriptional regulations coming from 31 recent, different experimental works available in the literature. As a result of the incorporation of these data, the new network doubles the size of previous data collections, incorporating more than a third of the entire genome of the bacterium. We also present an exhaustive topological ...
Structural and dynamical patterns on Online Social Networks: the Spanish May 15th Movement as a case study
This work represents our first contribution to a subject that has attracted a lot of interest in the last few years: the analysis of online social networks. The number of people using online social networks in their everyday life is continuously growing at a pace never saw before. This new kind of communication has an enormous impact on opinions, cultural trends, information spreading and even in the commercial success of ...
Impact of Human Behavioral Changes in Large-Scale Disease Spreading
Current modeling of infectious diseases allows for the study of realistic scenarios that include population heterogeneity, social structures, and mobility processes down to the individual level. The advances in the realism of epidemic description call for the explicit modeling of individual behavioral responses to the presence of disease within modeling frameworks. Here we formulate and analyze a metapopulation model that incorporates several scenarios of self-initiated behavioral changes into the mobility ...
Modeling Hyperpriming in Alzheimer's Disease
This work has to do with the application of Network Science to study several aspects of a degenerative disease: the Alzheimer. Alzheimer's Disease irremediably alters the proficiency of word search and retrieval processes even at its early stages. Such disruption can sometimes be paradoxical in specific language tasks, for example semantic priming. In this study, we focus on the striking side-effect of hyperpriming in Alzheimer's Disease patients, which has been ...
New Heterogeneous Mean-field Approach to epidemic spreading in complex networks
This work deals with the problem of how the spreading of diseases depends on structural patterns. The study contributes to further advance our understanding of epidemic spreading processes by proposing a non-perturbative formulation of the heterogeneous mean field approach that has been commonly used in the physics literature to deal with this kind of spreading phenomena. We propose non-perturbative equations without making any assumption about the proximity of the system ...
