Unravel the rotational and translational behavior of a single squirmer in flexible polymer solutionsat different Reynolds numbers
Microorganisms such as bacteria and algae navigate complex fluids, where their dynamics are vital for medical and industrial applications. However, the influence of the Reynolds number (Re) on the transport and rotational ...
Protocol for tailored in vitro neuronal networks on high-density microelectrode arrays with polydimethylsiloxane microstructures
Complementary metal-oxide-semiconductor (CMOS)-based high-density microelectrode arrays (HD-MEAs) enable neuronal recordings with high spatiotemporal resolution. However, integrating polydimethylsiloxane (PDMS) microstructures ...
Multiscale Field Theory for Network Flows
Network flows are pervasive, including the movement of people, transportation of goods, transmission of energy, and dissemination of information; they occur on a range of empirical interconnected systems, from designed ...
Mapping the structure and function of whole-mount retinal organoids
Cell therapy is a therapeutic avenue for retinal degenerative diseases. Photoreceptortransplantation faces challenges in obtaining high-quality and mature photoreceptors that caneffectively integrate and function, facilitating ...
Tunable dynamics of flexible magnetic microcrosses: synchronous rotation, breathing and out-of-plane arm overtaking
We combine colloidal self-assembly and soft-lithography techniques to realize flexible magnetic microcrosses that can be manipulated via external, time dependent magnetic fields. The crosses are characterized by a central ...
Role of connectivity anisotropies in the dynamics of cultured neuronal networks
An inherent challenge in designing laboratory-grown, engineered living neuronal networks lies in predicting the dynamic repertoire of the resulting network and its sensitivity to experimental variables. To fill this gap, ...
Citizen Science initiatives in climate-vulnerable neighbourhoods: a new transdisciplinary approach to tackle sustainability challenges?
According to the Spanish State Meteorological Agency (AEMET), the summer of 2025 (June 1-August 31) was exceptionally warm across Spain, with an average temperature of 24.2°C on the mainland. This value is 2.1°C above the ...
Modular architecture confers robustness to damage and facilitates recovery in spikingneural networks modeling in vitro neurons
Impaired brain function is restored following injury through dynamic processes that involve synaptic plasticity. This restoration is supported by the brain’s inherent modular organization, which promotes functional separation ...
Discounting the Distant Future: What Do Historical Bond Prices Imply about the Long-Term Discount Rate?
We present a thorough empirical study on real interest rates by also including risk aversion through the introduction of the market price of risk. From the viewpoint of complex systems science and its multidisciplinary ...
Influence of topology in the mobility enhancement of pulse-coupled oscillator synchronization
In this work we revisit the nonmonotonic behavior (NMB) of synchronization time with velocity reported for systems of mobile pulse-coupled oscillators (PCOs). We devise a control parameter that allows us to predict in which ...
Quasi-symmetries in complex networks: a dynamical model approach
The existence of symmetries in complex networks has a significant effect on network dynamic behaviour. Nevertheless, beyond topological symmetry, one should consider the fact that real-world networks are exposed to ...
Public libraries embrace citizen science: Strengths and challenges
Can public libraries become hubs for citizen science? In line with the principles of citizen science, this question was answered collaboratively with librarians from the Barcelona Network of Public Libraries who performed ...
Novel mechanism for oscillations in catchbonded motor-filament complexes
Generation of mechanical oscillations is ubiquitous to a wide variety of intracellular processes, ranging from activity of muscle fibers to oscillations of the mitotic spindle. The activity of motors plays a vital role in ...
Magnetically driven confined colloids: From enhanced diffusion to bidirectional transport
Inspired by previous experimental results, we use numerical simulations to investigate the collective dynamics of paramagnetic colloidal particles confined between two plates closer than twice the particle diameter and ...
Linear response theory and Green-Kubo relations for active matter
We address the question of how interacting active systems in a nonequilibrium steady state respond to an external perturbation. We establish an extended fluctuation-dissipation theorem for active Brownian particles (ABP), ...
Aligning active particles py package
The package performs molecular-dynamics-like agent-based simulations for models of aligning self-propelled particles in two dimensions such as e.g. the seminal Vicsek model or variants of it. In one class of the covered ...
Three-State Opinion Model on Complex Topologies
We investigate opinion diffusion on complex networks and the interplay between the existence of neutral opinion states and non-trivial network structures. For this purpose, we apply a three-state opinion model based on ...
Noise focusing in neuronal tissues: Symmetry breaking and localization in excitable networks with quenched disorder
We introduce a coarse-grained stochastic model for the spontaneous activity of neuronal cultures to explain the phenomenon of noise focusing, which entails localization of the noise activity in excitable networks with ...
Inferring structure of cortical neuronal networks from activity data: A statistical physics approach
Understanding the relation between cortical neuronal network structure and neuronal activity is a fundamental unresolved question in neuroscience, with implications to our understanding of the mechanism by which neuronal ...
Noise-induced polarization switching in complex networks
The combination of bistability and noise is ubiquitous in complex systems, from biology to social interactions, and has important implications for their functioning and resilience. Here we use a simple three-state dynamical ...
