This paper studies a generalized nonlinear evolution equation. Using the homotopic mapping method, it constructs a corresponding homotopic mapping transform. Selecting a suitable initial approximation and using homotopic mapping, it obtains an approximate solution with an arbitrary degree of accuracy for the solitary wave. From the approximate solution obtained by using the homotopic mapping method, it possesses a good accuracy.

The new-generation of E-government systems should be able to integrate large amounts of heterogeneous data sources located in distributed networks like the Internet. Web Services technologies are an increasingly popular way of building distributed systems. Therefore, the advantages of Web Services orchestration in E-government processes integration and services come into perspective. In this paper, Web Services system structure and stack are presented, and we describe the Web Services-based E-government architecture, that is designed as a holistic service framework for the deployment of E-government services.

In this paper, we consider the following second order three-point boundary value problem u″（t）＋a（t）f（u（t））=0,0〈t〈1,u（0）-u（1）=0,u＇（0）-u＇（1）=u（1/2）,where a ：（0, 1） → [0, ∞） is symmetric on （0, 1） and may be singular at t = 0 and t = 1, f ： [0, ∞） → [O, ∞） is continuous. By using Krasnoselskii＇s fixed point theorem ia a cone, we get some existence results of positive solutions for the problem. The associated Green＇s function for the three-point boundary value problem is also given.

Security of wireless sensor networks has received considerable attention. It is a critical challenge to find out suitable encryption schemes for wireless sensor networks due to limitations of power, computation capability and storage resources of these networks. Many encryption schemes based on asymmetric and symmetric have been investigated. In this paper, we present an authenticated identity-based key encryption scheme for wireless sensor networks. We first review briefly about identity-based encryption and decryption, particularly, the Boneh-Franklin algorithms, then describe an authenticated identity-based key encryption scheme based on Boneh-Franklin algorithms, and finally show the integrity of our scheme and discuss its efficiency and security by comparing it with other asymmetric and symmetric encryption schemes.

Using bosonization and phase shift representation, we rigorously treat backward scattering of electrons on an impurity in a one-dimensional interacting electronic system, and demonstrate that correlation exponents of the system depend on a phase shift induced by the backward scattering, and usual exponent duality of the correlation functions between ultraviolet and infrared fixed points comes from the phase shift dependence of the correlation exponents. Finally, we study the tunnelling conductance of the system at zero temperature and obtain a modified Landauer-Bütiker formula.
