Increasing power-law range in avalanche amplitude and energy distributions
Power-law-type probability density functions spanning several orders of magnitude are found for different avalanche properties. We propose a methodology to overcome empirical constraints that limit the range of truncated ...
Spontaneous chiralization of polar active colloids
Polar active particles constitute a wide class of active matter that is able to propel along a preferential direction, given by their polar axis. Here, we demonstrate a generic active mechanism that leads to their spontaneous ...
Quantifying human engagement into playful activities
Engaging in playful activities, such as playing a musical instrument, learning a language, or performing sports, is a fundamental aspect of human life. We present a quantitative empirical analysis of the engagement dynamics ...
Chitinase 3-like 1 is neurotoxic in multiple sclerosis patient-derived cortical neurons
We are pleased to present our latest findings regarding the neurotoxic role of Chitinase 3-like 1 (CHI3L1) in multiple sclerosis (MS). CHI3L1, a 40 kD glycoprotein, is primarily produced by activated astrocytes and microglia ...
Parallel hybrid simulations of block copolymer nanocomposites using Coarray Fortran
Computer simulations of experimentally comparable system sizes in soft matter often require considerable elapsed times. The use of many cores can reduce the needed time, ideally proportionally to the number of processors. ...
Dynamics and interactions of magnetically driven colloidal microrotors
We study the pair interactions between magnetically driven colloidal microrotors with an anisotropic shape. An external precessing magnetic field induces a torque to these particles spinning them at a fixed angular frequency. ...
Citizen science for social physics: digital tools and participation
Social physics is an active and diverse field in which many scientists with formal training in physics study a broad class of complex social phenomena. Social physics investigates societal problems but most often does not ...
Stationary patterns in star networks of bistable units: theory and application to chemical reactions
We present theoretical and experimental studies on pattern formation with bistable dynamical units coupled in a star network configuration. By applying a localized perturbation to the central or the peripheral elements, ...
Fluctuation-Dissipation Relations in the absence of Detailed Balance: formalism and applications to Active Matter
We present a comprehensive study about the relationship between the way Detailed Balance is broken in non-equilibrium systems and the resulting violations of the Fluctuation-Dissipation Theorem. Starting from stochastic ...
Food-Bridging: A New Network Construction to Unveil the Principles of Cooking
In this manuscript we propose, analyse, and discuss a possible new principle behind traditional cuisine: the Food-bridging hypothesis and its comparison with the food-pairing hypothesis using the same dataset and graphical ...
Impact of Physical Obstacles on the Structural and Effective Connectivity of in silico Neuronal Circuits
Scaffolds and patterned substrates are among the most successful strategies to dictate the connectivity between neurons in culture. Here, we used numerical simulations to investigate the capacity of physical obstacles ...
Non-spherical nanoparticles in block copolymer composites: nanosquares, nanorods and diamond
A hybrid two-dimensional block copolymer (BCP) nanocomposite computational model is proposed to study nanoparticles (NPs) with a generalized shape including square, rectangle, and rhombus. Simulations are used to study the ...
Neuronal Cultures: Exploring Biophysics, Complex Systems, and Medicine in a Dish
Neuronal cultures are one of the most important experimental models in modern interdisciplinary neuroscience, allowing to investigate in a control environment the emergence of complex behavior from an ensemble of interconnected ...
Functionability in complex networks: Leading nodes for the transition from structural to functional networks through remote asynchronization
Complex networks are essentially heterogeneous not only in the basic properties of the constituent nodes, such as their degree, but also in the effects that these have on the global dynamical properties of the network. ...
Multiscale voter model on real networks
We introduce the Multiscale Voter Model (MVM) to investigate clan influence at multiple scales—family, neighborhood, political party…—in opinion formation on real complex networks. Clans, consisting of similar nodes, are ...
Network Geometry
Networks are finite metric spaces, with distances defined by the shortest paths between nodes. However, this is not the only form of network geometry: two others are the geometry of latent spaces underlying many networks ...
Elastic and dynamic properties of membrane phase-field models
Phase-field models have been extensively used to study interfacial phenomena, from solidification to vesicle dynamics. In this article, we analyze a phase-field model that captures the relevant physical features that ...
Reconstructing social networks of Late Glacial and Holocene hunter-gatherers to understand cultural evolution
Culture is increasingly being framed as a driver of human phenotypes and behaviour. Yet very little is known about variations in the patterns of past social interactions between humans in cultural evolution. The archaeological ...
Interplay between social infuence and competitive strategical games in multiplex networks
We present a model that takes into account the coupling between evolutionary game dynamics and social influence. Importantly, social influence and game dynamics take place in different domains, which we model as different ...
Large-scale citizen science provides high-resolution nitrogen dioxide values and health impact while enhancing community knowledge and collective action
We present outcomes from a large-scale air quality citizen science campaign (xAire, 725 measurements) to demonstrate its positive contribution in the interplay between advances in exposure assessment and developments in ...
