摘要：
In this paper, the scale-free network discovery is reviewed and the scale-free characteristic of complex networks is described, based on the strategies which are proposed against vulnerability of hubs in scale-free networks. The strategies show how hierarchy is formed by controlling hubs and how nodes generate super-cube consists of virtual nodes in detail. The hierarchy of nodes has better flexibility and fault tolerance;besides, the super-cube structure has fault reconfiguration compared with hubs. Both have higher robustness and steadiness shown by simulation.
摘要：
This paper proposes an energy efficient clustering formation algorithm for wireless sensor network, which is called ACE-CILP algorithm according to considering the energy consumption as an optimization parameter. The algorithm can divide a sensor network into a few clusters and select a cluster head base on weight value that leads to more uniform energy dissipation evenly among all sensor nodes. The simulation results show that ACE-CILP algorithm achieves its intention of consuming less energy, equalizing the energy consumption of all the nodes, as well as extending the network lifetime perfectly.

摘要：
With the energy constrained nature of wireless sensors, it is a substantial design issue to make efficient use of battery power in order to increase their lifetime. An optimal routing approach is critical to prolong the lifetime of the network. This paper presents a novel clustering scheme integrating hierarchical method on the basis of classical routing algorithm. Simulation results show that the new scheme efficiently mitigates the hot spot problem in WSN and achieves much improvement in network lifetime and load balance compared to the old algorithm LEACH, which is the most promising hierarchical routing algorithm to date.

摘要：
The decays of J/psi ->omega K (K) over bar pi and J/psi ->phi K (K) over bar pi are studied using 5.8x10(7) J/psi events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider (BEPC). The K(S)(0)K(+/-)pi(-/+) and K(+)K(-)pi(0) systems, produced in J/psi ->omega K (K) over bar pi, have enhancements in the invariant mass distributions at around 1.44 GeV/c(2). However, there is no evidence for mass enhancements in the K (K) over bar pi system in J/psi ->phi K (K) over bar pi. The branching fractions of J/psi ->omega K(S)(0)K(+/-)pi(-/+), phi K(S)(0)K(+/-)pi(-/+), omega K*(K) over bar +c.c., and phi K*(K) over bar +c.c. are obtained, and the J/psi ->eta K(S)(0)K(+/-)pi(-/+) branching fraction is measured for the first time.

摘要：
In this paper, we propose a new dual-band filtering method for performance enhancement of the chirp spread spectrum (CSS) system in the IEEE 802.15.4a standard. The CSS signals are composed of low- and high-band signals which are alternatively transmitted in time. If we use only one conventional channel filter, the signal-to-noise ratio (SNR) performance in the receiver is degraded, because the low- and high-band signals have a different frequency characteristics. The dual-band filtering method proposed in this paper is based on two filters which are designed to be matched well with alternatively received CSS signals and excludes the undesired noise.
