Habitat fragmentation promotes spatial scale separation under resource competition Open
Habitat fragmentation, often driven by human activities, alters ecological landscapes by disrupting connectivity and reshaping species interactions. In such fragmented environments, habitats can be modeled as networks, where individuals di…

The Frequency Response of Networks as Open Systems Open
Many biological, technological, and social systems are effectively networks of interacting individual systems. Typically, these networks are not isolated objects, but interact with their environment through both signals and information tha…

Mesoscale community organization governs epidemic onset and spread in metapopulations Open
Understanding how internal community structure shapes the course of epidemics remains a fundamental challenge in modeling real-world populations. Standard metapopulation models often assume uniform mixing within communities, overlooking ho…

Extreme vulnerability to intruder attacks destabilizes network dynamics Open
Consensus, synchronization, formation control, and power grid balance are all examples of virtuous dynamical states that may arise in networks. Here we focus on how such states can be destabilized from a fundamental perspective; namely, we…

Reply to Comment on "Synchronization dynamics in non-normal networks: the trade-off for optimality" Open
We reply to the recent note "Comment on Synchronization dynamics in non-normal networks: the trade-off for optimality", showing that the authors base their claims mainly on general theoretical arguments that do not necessarily invalidate t…

Hierarchical route to the emergence of leader nodes in real-world networks Open
A large number of complex systems, naturally emerging in various domains, are well described by directed networks, resulting in numerous interesting features that are absent from their undirected counterparts. Among these properties is a s…

A minimally invasive neurostimulation method for controlling abnormal synchronisation in the neuronal activity Open
Many collective phenomena in Nature emerge from the -partial- synchronisation of the units comprising a system. In the case of the brain, this self-organised process allows groups of neurons to fire in highly intricate partially synchronis…
