	1. A multi-local-world model for complex networks

	Abstract:The nodes in a community within a network are much more connected to each other than to the others outside the community in the same network. This phenomenon has been commonly observed from many real-world networks, ranging from social to biological even to technical networks. Meanwhile, the number of communities in some real-world networks, such as the Internet and most social networks, are evolving with time. To model this kind of networks, the present paper proposes a multi-local-world (MLW) model to capture and describe their essential topological properties. Based on the mean-field theory, the degree distribution of this model is obtained analytically, showing that the generated network has a novel topological feature as being not completely random nor completely scale-free but behaving somewhere between them.

	2. The heterogenous models of the AS-level Internet may not fit to sustain its functioning

	Abstract:A variety of topological metrics have been proposed to determine whether or not a proposed model is suitable for modeling the AS-level Internet topology, which have led to a common belief that the average degree, degree distribution and joint degree distribution are sufficient for reproducing most fundamental structural characteristics. Rather than discussing such structural characteristics, in this paper we focus on the performance comparison of different AS-level Internet models, which allows us to determine whether or not the currently proposed AS-level Internet models can sustain a certain Internet function of interest. By taking the network performances in resisting random failures and intentional attacks as an indicator, we show that some models with almost same values in their average degree, degree distribution and joint degree distribution can exhibit very different behaviors. Our findings provide good insights on how to improve the resistibility of the Internet and a complex heterogeneous network in general. More importantly, our observations suggest that there are risks when applying new protocols and algorithms to the real Internet.

	3. Mass Is Not Constant in a Gravitational Field
	Zhan Likui
	Physics 30 November 2010
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Various gravitation theories predict that a star with large enough mass will shrink down to a final point, gravitational singularity. The gravitational singularity is always one of the difficult problems in the world. This work reviews some kinds of difficulties which relates to gravitational fields. Based on experimental analysis and theoretical verification, a new hypothesis regarding mass in gravitational fields is presented. In this case, the gravitational singularity no longer appears and the meaning of gravitation is simple to determine. The hypothesis is also the result that various facts and theories have been repeatedly weighed. In the end, a method for verification of the hypothesis is proposed.

	4. Area spectrum of large AdS black hole from quasinormal modes

	Abstract:Using the new physical interpretation of quasinormal modes proposed by Maggiore, we calculate the area and entropy spectra for the 3-dimensional and 5-dimensional large Ads black hole. The spectra are obtained by imposing the Bohr-Sommerfeld quantization condition and the adiabatic invariant quantity. With this semiclassical method, we find that the spacings of the area and entropy spectra aare equidistant and independent of the Ads radius of the black hole for both the casess. However, the spacings of the spectra are not the same for different dimension of space-time. The equidistant area spectra will be broken when the black hole has other paprameters (i.e., charge and angular momentum) of in a non-Einstein's gravity theory.

	5. Temperature and Energy of 4-dimensional Black Holes from Entropic Force

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:We investigate the temperature and energy on holographic screens for 4-dimensional black holes with the entropic force idea proposed by Verlinde. We find that the “Unruh-Verlinde temperature” is equal to the Hawking temperature on the horizon and can be considered as a generalize Hawking temperature on the holographic screen outside the horizons. The energy on the holographic screen is not the black hole mass $M$ but the reduced mass $M_0$, which is related to the black hole parameters. With the replacement of the black hole mass $M$ by the reduced mass $M_0$, the entropic force can be written as $F= frac{GmM_0}{r^2}$, which could be tested by experiments.

	6. Cooperative Behavior in a Model of Evolutionary Snowdrift Games with N-person Interactions
	Zheng Dafang,Yin Haiping,Chan ChunH,Hui Poming
	Physics 26 March 2010
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:We propose a model of evolutionary snowdrift game with $N$-person interactions and study the effects of multi-person interactions on the emergence of cooperation. An exact $N$-th-order equation for the equilibrium density of cooperators $x^$ is derived for a well-mixed population using the approach of replicator dynamics. The results show that the extent of cooperation drops with increasing cost-to-benefit ratio and the number $N$ of interaction persons in a group, with $x^{}sim1/N$ for large $N$. An algorithm for numerical simulations is constructed for the model. The simulation results are in good agreements with theoretical results of the replicator dynamics.

	Abstract:We investigate how the density operator of a squeezed chaotic field (a mixed state) evolves in the amplitude dissipative channel. We demonstrate that the evolved density operator ρ(t) is in a Gaussian quadratic form, and the Q-function of ρ(t) is derived, which manifestly exhibits the dissipation.

	8. Probabilistic and controlled teleportation of an arbitrary single-qubit state via one-dimensional four-qubit cluster-type state

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:We propose a tripartite scheme for probabilistically teleporting an arbitrary single-qubit state with one-dimensional four-qubit cluster-type state as the quantum channel. In the scheme, Alice and Bob both perform a Bell-state measurement (BSM) on their respective qubit pair in their hands and announce the measurement results via classical communication. With the help of the sender and the controller, the receiver can reconstruct the original state with a certain probability by introducing an auxiliary qubit and making appropriate unitary operations and positive operator-valued measure (POVM). Moreover, the total success probability and classical communication cost of the present scheme are also calculated

	9. Stable matter-wave packets in a traveling lattice potential

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:We consider a Bose-Einstein condensate (BEC) driven by a traveling lattice potential and derive an exact traveling-wave solution of the one-dimensional (1D) Gross-Pitaevskii equation (GPE), which satisfies a balance condition between the optical potential and interatomic interaction. The balance condition means the conservation of the total potential, and the exact solution contains some Bloch-like states and shows that the matter-wave has spatial profile in the form of sinusoid wave and propagates like a quasi-free particle with the lattice velocity.

	10. Synchronization in Nearest-neighbor Coupled Oscillators with A Few Shortcuts

	Physics 12 February 2010
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Synchronous dynamics in nearest-neighbor coupled chaotic oscillators with a few shortcuts is explored. The existence and stability of the partially synchronous states are studied. It is revealed that different topology of connections among oscillators gives rise to synchronized or unsynchronized dynamics. The criterion for the emergence of the partially synchronized states on a given network is theoretically discussed and proposed. The synchronization for the two-shortcut case are studied in detail, i.e., we prove that partial synchronization is always achievable for parallel networks, while the stability of partial synchronization depends crucially on the topology of connections for crossed and lambda networks. The phase diagram for the transition to partial synchronization is given for different cases. The manifestations for the transition to partial synchronization in relating to the Lyapunov exponent spectra are found and interpreted. These explorations indicate that the microscopic topology of the network have a profound effect on the macroscopic dynamical features of the system.
