The real core model and its scales

Daniel W. Cunningham
1995 Annals of Pure and Applied Logic  
This paper introduces the real core model K(R) and determines the extent of scales in this inner model.  ...  K(R) is an analog of Dodd-Jensen's core model K and contains L(R), the smallest inner model of ZF containing the reals R. We define iterable real premice & and show that C, (.  ...  We call R the set of reals and regard R as a topological space by giving it the product topology, using the discrete topology on CO. In this paper we study the inner model K(R), the real core model.  ...

Core Percolation on Complex Networks

Yang-Yu Liu, Endre Csóka, Haijun Zhou, Márton Pósfai
2012 Physical Review Letters  
We derive the condition for core percolation and find that purely scale-free networks have no core for any degree exponents.  ...  We also apply our theory to real-world directed networks and find, surprisingly, that they often have much larger core sizes as compared to random models.  ...  We also apply our theory to real-world directed networks and find, surprisingly, that they often have much larger core sizes as compared to random models.  ...

Dynamic power management (DPM) and dynamic voltage scaling (DVS) are effective control techniques to reduce the energy consumption.  ...  We present a realtime energy saving scheduling (RESS) algorithm using DPM and DVS to reduce the energy cost for chip multiprocessor (CMP) systems.  ...  If PM observes there are idle cores and cores with very long queue at same time, it will migrate jobs from the busy core to the idle one.  ...

Percolation on random networks with arbitraryk-core structure

2013 Physical Review E  
We then solve exactly the bond percolation problem on the HRN model and produce fast and precise analytical estimates for the corresponding real networks.  ...  The k-core decomposition of a network has thus far mainly served as a powerful tool for the empirical study of complex networks. We now propose its explicit integration in a theoretical model.  ...  Adding clustering to the HRN is expected to shift its prediction toward higher values of T , i.e., closer to the results from the real network.  ...

The fraction of the total mass in the star cluster which ends up in a single massive object scales with the total mass of the cluster and its relaxation time.  ...  Wild extrapolation from the relatively small masses of the studied systems to the cores of galactic nuclei may indicate that the massive black holes in these systems have formed in a similar way.  ...  Drexel University and the University of Tokyo are deeply acknowledged for their hospitality and the use of their GRAPE hardware.  ...
