Power-laws and Non-Power-laws in Dark Matter Halos
Simulated dark matter profiles are often modelled as a ‘NFW’ density profile rather than a single power law. Recently, attention has turned to the rather rigorous power-law behaviour exhibited by the ‘pseudo phase-space density’ of the dark matter halo, which is defined dimensionally in terms of the local density and velocity dispersion of the dark matter particles. The non-power-law behaviour ...
متن کاملPower laws in biology
Why live larger mammals longer than smaller ones? Why is the energy consumption per body mass of a mouse six times higher than that of a human? These questions and many others dealing with biological allometry kept and keep biologists busy since the second half of nineteenth century and as it seems, the ultimate answers have not yet been given. Analyzing allometry is particularly attractive sin...
متن کاملA Survey of Equilibrium Analysis in Spatial Models of Elections
Elections, as the institution through which citizens choose their political agents, are at the core of representative democracy. It is therefore appropriate that they occupy a central position in the study of democratic politics. The formal analysis of elections traces back to the work of Hotelling (1929), Downs (1957), and Black (1958), who apply mathematical methods to understand the equilibr...
متن کاملPower laws in biological networks
The rapidly developing theory of complex networks indicates that real networks are not random, but have a highly robust large-scale architecture, governed by strict organizational principles. Here, we focus on the properties of biological networks, discussing their scale-free and hierarchical features. We illustrate the major network characteristics using examples from the metabolic network of ...
