Degree distributions of growing networks.
The in-degree and out-degree distributions of a growing network model are determined. The in-degree is the number of incoming links to a given node (and vice versa for out-degree). The network is built by (i) creation of new nodes which each immediately attach to a preexisting node, and (ii) creation of new links between preexisting nodes. This process naturally generates correlated in-degree a...
متن کاملDegree-degree correlations in directed networks with heavy-tailed degrees
In network theory, Pearson’s correlation coefficients are most commonly used to measure the degree assortativity of a network. We investigate the behavior of these coefficients in the setting of directed networks with heavy-tailed degree sequences. We prove that for graphs where the inand out-degree sequences satisfy a power law, Pearson’s correlation coefficients converge to a non-negative num...

We investigate the behavior of these coefficients in the setting of directed networks with heavy-tailed degree sequences. We prove that for graphs where the inand out-degree sequences satisfy a power lawwith realistic parameters, Pearson’s correlation coefficients conve...
متن کاملGrowing degree-days: one equation, two interpretations
Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [(T,,, + TM,,)/2] T,,,,, where T, and T,,, are daily maximum and minimum air temperature, respectively, and T,, is the base temperature. Two methods of interpreting this equation for calculating GDD are: (1) if the daily mean temperature is les...
متن کاملDegree Correlations in Directed Scale-Free Networks
Scale-free networks, in which the distribution of the degrees obeys a power-law, are ubiquitous in the study of complex systems. One basic network property that relates to the structure of the links found is the degree assortativity, which is a measure of the correlation between the degrees of the nodes at the end of the links. Degree correlations are known to affect both the structure of a net...
