Nonmonotonic percolation threshold in correlated networks and hypergraphs
L. D. Valdez, C. E. La Rocca
We study the effect of assortative and disassortative mixing on the robustness of networks under random node failures. For ordinary (dyadic) networks, by using the generating funct…
Epidemic control in networks with cliques
L. D. Valdez, L. Vassallo, L. A. Braunstein
Social units, such as households and schools, can play an important role in controlling epidemic outbreaks. In this work, we study an epidemic model with a prompt quarantine measur…
Emergent networks in fractional percolation
L. D. Valdez, L. A. Braunstein
Real networks are vulnerable to random failures and malicious attacks. However, when a node is harmed or damaged, it may remain partially functional, which helps to maintain the ov…
Cascading Failures in Complex Networks
Lucas D. Valdez, Louis Shekhtman, Cristian E. La Rocca +5
Cascading failure is a potentially devastating process that spreads on real-world complex networks and can impact the integrity of wide-ranging infrastructures, natural systems, an…
Role of bridge nodes in epidemic spreading: Different regimes and crossovers
Jing Ma, Lucas D. Valdez, Lidia A. Braunstein
Power-law behaviors are common in many disciplines, especially in network science. Real-world networks, like disease spreading among people, are more likely to be interconnected co…
Epidemic spreading on modular networks: The fear to declare a pandemic
L. D. Valdez, L. A. Braunstein, S. Havlin
In the past few decades, the frequency of pandemics has been increased due to the growth of urbanization and mobility among countries. Since a disease spreading in one country coul…
Insights into bootstrap percolation: Its equivalence with k-core percolation and the giant component
M. A. Di Muro, L. D. Valdez, S. V. Buldyrev +2
K-core and bootstrap percolation are widely studied models that have been used to represent and understand diverse deactivation and activation processes in natural and social syste…
Cascading Failures in Interdependent Networks with Multiple Supply-Demand Links and Functionality Thresholds
M. A. Di Muro, L. D. Valdez, H. H. A. Rêgo +3
Various social, financial, biological and technological systems can be modeled by interdependent networks. It has been assumed that in order to remain functional, nodes in one netw…
Failure-recovery model with competition between failures in complex networks: a dynamical approach
L. D. Valdez, M. A. Di Muro, L. A. Braunstein
Real systems are usually composed by units or nodes whose activity can be interrupted and restored intermittently due to complex interactions not only with the environment, but als…
Triple point induced by targeted autonomization on interdependent scale free networks
L. D. Valdez, P. A. Macri, L. A. Braunstein
Many man-made networks support each other to provide efficient services and resources to the customers, despite that this support produces a strong interdependency between the indi…
Social distancing strategies against disease spreading
L. D. Valdez, C. Buono, P. A. Macri +1
The recurrent infectious diseases and their increasing impact on the society has promoted the study of strategies to slow down the epidemic spreading. In this review we outline the…
Triple Point in Correlated Interdependent Networks
L. D. Valdez, P. A. Macri, H. E. Stanley +1
Many real-world networks depend on other networks, often in non-trivial ways, to maintain their functionality. These interdependent "networks of networks" are often extremely fragi…
Temporal percolation of a susceptible adaptive network
L. D. Valdez, P. A. Macri, L. A. Braunstein
In the last decades, many authors have used the susceptible-infected-recovered model to study the impact of the disease spreading on the evolution of the infected individuals. Howe…
Temporal percolation of the susceptible network in an epidemic spreading
L. D. Valdez, P. A. Macri, L. A. Braunstein
In this work, we study the evolution of the susceptible individuals during the spread of an epidemic modeled by the susceptible-infected-recovered (SIR) process spreading on the to…
Intermittent social distancing strategy for epidemic control
L. D. Valdez, P. A. Macri, L. A. Braunstein
We study the critical effect of an intermittent social distancing strategy on the propagation of epidemics in adaptive complex networks. We characterize the effect of our strategy…
Effect of degree correlations above the first shell on the percolation transition
L. D. Valdez, C. Buono, L. A. Braunstein +1
The use of degree-degree correlations to model realistic networks which are characterized by their Pearson's coefficient, has become widespread. However the effect on how different…
