We investigate the dynamic relaxation of random walks on temporal networks by focusing in the recently proposed activity driven model [Perra et al. Sci. Rep. srep00469 (2012)]. For realistic activity distributions with a power-law form, we observe the presence of a very slow relaxation dynamics compatible with aging effects. A theoretical description of this processes in achieved by means of a ...

In delay tolerant networks (DTNs), broadcasting is an important routing function that supports the distribution of data to all users in the network. Efficient broadcasting in DTNs is a challenging problem due to the lack of continuous network connectivity. In this paper, we consider the limited bandwidth scenario for DTN broadcasting. Our scheme aims to provide a ticket-based multiple packet br...

Since a spatial distribution of communication requests is inhomogeneous and related to a population, in constructing a network, it is crucial for delivering packets on short paths through the links between proximity nodes and for distributing the load of nodes how to locate the nodes as base-stations on a realistic wireless environment. In this paper, from viewpoints of complex network science ...

Precursory fracture induced electromagnetic (EM) emissions, rooted in opening cracks and ranging from MHz to kHz, with the MHz appearing earlier, are produced and detected both at laboratory and geophysical scale. Recently, we have proposed the following two epochs/stages model of EQ generation: (i) The final kHz part is triggered by the fracture of high strength and large asperities that are d...

channel pores where no very long jumps are possible. For pores with an elevation that varies like a random walk (red) and alternating pores (blue) the scaled mean square displacement /t is asymp-totically constant. 1. Introduction In general, diffusion of gas particles depends on the collisions between the gas molecules as well as on the collisions of the gas with the pore walls. Of pa...

Analysis of dynamical phenomena in financial markets have revealed the existence of several features that appear to be invariant with respect to details of the specific markets being considered. While some of these “stylized facts”, such as the inverse cubic law distribution of price returns indeed seem to be universal, there is less consensus about other phenomena. In particular, there has bee...

Human mobility patterns (HMP) have become of interest to a variety of disciplines. The increasing availability of empirical data enables researchers to analyze patterns of people's movements. Recent work suggested that HMP follow a Levy-flight distribution and present regularity. Here, we present an innovative agent-based model that simulates HMP for various purposes. It is based on the combina...
