Open AccessThermodynamic analog of integrate-and-fire neuronal networks by maximum entropy modelling
Recent results have evidenced that spontaneous brain activity signals are organized in bursts with scale free features and long-range spatio-temporal correlations. These observations have stimulated a theoreti...

Correction to: Influence of cancer and acute inflammatory disease on taste perception: a clinical pilot study
The Acknowledgement Statement was incorrect in the original publication of this article [1] and the previous correction note [2]. The correct statement is as follows:

Open AccessThree cooperative mechanisms required for recovery after brain damage
Stroke is one of the main causes of human disabilities. Experimental observations indicate that several mechanisms are activated during the recovery of functional activity after a stroke. Here we unveil how th...

Correction to: Influence of cancer and acute inflammatory disease on taste perception: a clinical pilot study
The “Acknowledgment Statement” of the published paper is incorrect. The correct statement should be the below: Acknowledgements We thank Sarah Vogel for her support in taste test realization and Yvonne Sauermann ...

Open AccessA comparison of hydrological and topological watersheds
We introduce the hydrological watershed, a watershed where water can penetrate the soil, and compare it with the topological watershed for a two-dimensional landscape. For this purpose, we measure the fractal ...

Segregation of charged particles under shear
We study segregation of a binary mixture of differently charged particles under shear using particle-based simulations. We simulate particle dynamics using a discrete-element model including electrostatic inte...

Open AccessSchramm-Loewner evolution and perimeter of percolation clusters of correlated random landscapes
Motivated by the fact that many physical landscapes are characterized by long-range height-height correlations that are quantified by the Hurst exponent H, we investigate the statistical properties of the iso-hei...

Open AccessInfluence of cancer and acute inflammatory disease on taste perception: a clinical pilot study
Cancer patients are at high risk of malnutrition and tumor cachexia further increasing morbidity and mortality. Reasons for cachexia are not clear yet, but inflammatory processes as well as the occurrence of t...

Open AccessTargeted Recovery as an Effective Strategy against Epidemic Spreading
We propose a targeted intervention protocol where recovery is restricted to individuals that have the least number of infected neighbours. Our recovery strategy is highly efficient on any kind of network, sinc...

Open AccessThe influence of statistical properties of Fourier coefficients on random Gaussian surfaces
Many examples of natural systems can be described by random Gaussian surfaces. Much can be learned by analyzing the Fourier expansion of the surfaces, from which it is possible to determine the corresponding H...

Open AccessEnergy dissipation in flows through curved spaces
Fluid dynamics in intrinsically curved geometries is encountered in many physical systems in nature, ranging from microscopic bio-membranes all the way up to general relativity at cosmological scales. Despite ...

Open AccessFailure and recovery in dynamical networks
Failure, damage spread and recovery crucially underlie many spatially embedded networked systems ranging from transportation structures to the human body. Here we study the interplay between spontaneous damage...

Open AccessSelf-charging of identical grains in the absence of an external field
We investigate the electrostatic charging of an agitated bed of identical grains using simulations, mathematical modeling, and experiments. We simulate charging with a discrete-element model including electric...

Open AccessSynaptic plasticity and neuronal refractory time cause scaling behaviour of neuronal avalanches
Neuronal avalanches measured in vitro and in vivo in different cortical networks consistently exhibit power law behaviour for the size and duration distributions with exponents typical for a mean field self-organ...

Open AccessCrumpling Damaged Graphene
Through molecular mechanics we find that non-covalent interactions modify the fractality of crumpled damaged graphene. Pristine graphene membranes are damaged by adding random vacancies and carbon-hydrogen bon...

Analysis of the velocity field of granular hopper flow
We report the analysis of radial characteristics of the flow of granular material through a conical hopper. The discharge is simulated for various orifice sizes and hopper opening angles. Velocity profiles are...

Open AccessTemporal correlations in neuronal avalanche occurrence
Ongoing cortical activity consists of sequences of synchronized bursts, named neuronal avalanches, whose size and duration are power law distributed. These features have been observed in a variety of systems a...

Open AccessConformal Invariance of Graphene Sheets
Suspended graphene sheets exhibit correlated random deformations that can be studied under the framework of rough surfaces with a Hurst (roughness) exponent 0.72 ± 0.01. Here, we show that, independent of the ...

Open AccessEmergence of core–peripheries in networks
A number of important transport networks, such as the airline and trade networks of the world, exhibit a characteristic core–periphery structure, wherein a few nodes are highly interconnected and the rest of t...
