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 ...
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 ...
Navigable maps of structural brain networks across species
Connectomes are spatially embedded networks whose architecture has been shaped by physical constraints and communication needs throughout evolution. Using a decentralized navigation protocol, we investigate the relationship ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Degeneracy and hysteresis in a bidisperse colloidal ice
We use numerical simulations to investigate the low-energy states of a bidisperse colloidal ice, realized by confining two types of magnetic particles into double wells of different lengths. For this system, theoretical ...
