Galerkin finite element approximation for semilinear stochastic time-tempered fractional wave equations with multiplicative white noise and fractional Gaussian noise

To model wave propagation in inhomogeneous media with frequency-dependent power-law attenuation, it is needed to use the fractional powers of symmetric coercive elliptic operators in space and the Caputo tempered fractional derivative in time. Expand abstract.

Avalanches on the Complex Network of Rigan Earthquake, Virtual Seismometer Technique, Criticality and Seismic Cycle

We base our study on the statistical analysis of the Rigan earthquake 2010 December 20, which consists of estimating the earthquake network by means of virtual seismometer technique, and also considering the avalanche-type dynamics on top of this complex network. Expand abstract.

On the Strong Attraction Limit for a Class of Nonlocal Interaction Energies

This note concerns the problem of minimizing a certain family of nonlocal energy functionals over measures on $\mathbb{R}^n$, subject to a mass constraint, in a strong attraction limit. Expand abstract.

Engel's law in the commodity composition of exports

The export shares of commodity categories of a country are related to its GDP by a power-law with the exponents characterizing the GDP-elasticity of their export shares. Expand abstract.

Universal power law decay in the dynamic hysteresis of an optical cavity with non-instantaneous photon-photon interactions

Our results offer new perspectives for exploring non-Markovian dynamics of light using arrays of bistable cavities with low quality factors, driven by low laser powers, and at room temperature. Expand abstract.

Non-standard anomalous heat conduction in harmonic chains with correlated isotopic disorder

We address the general problem of heat conduction in one dimensional harmonic chain, with correlated isotopic disorder, attached at its ends to white noise or oscillator heat baths. Expand abstract.

Generating large scale-free networks with the Chung-Lu random graph model

Being able to produce synthetic networks by means of generative random graph models and scalable algorithms is a recurring tool-of-the-trade in network analysis, as it provides a well founded basis for the statistical analysis of various properties in real-world networks. Expand abstract.

Out-of-equilibrium phase diagram of long-range superconductors

We construct the rich dynamical phase diagram of free-fermionic chains with power-law hopping and pairing, and provide analytic and numerical evidence showing a direct connection between nonanalyticities of the return rate and zero crossings of the string order parameter. Expand abstract.

Renormalization group approach to power-law modeling of complex metabolic networks

As we shall see, according to the renormalization group point of view the answer is positive, as far as power-laws are the critical solutions of the renormalization group transformation, namely power-law rate-laws are the renormalization group invariant solutions. Expand abstract.

Power-Law Dynamics in Cortical Excitability as probed by Early Somatosensory Evoked Responses

As these dynamics covaried with pre-stimulus alpha oscillations, we establish a functional link between ongoing and evoked activity and argue that the co-emergence of similar temporal power-laws may originate from neuronal networks poised close to a critical state, representing a parsimonious organizing principle of...
