With the popularization of network and the continuous development of computer technology, as a "nuisance" in modern society, the computer virus has brought the threat to computer users. As a special computer program, the computer viruses have the characteristics of offensive and prone. Using the law prevention and control method can help us to carry out the computer virus prevention and treatment. In this paper, based on the synergetic theory of computer virus prevention and control, the legal countermeasure of computer virus prevention and control was analyzed, furthermore, according to increase the strike strength on computer virus transmission, the computer virus was prevented effectively.

Cyclin-dependent kinase 5 (Cdk5) is an important serine/threonine kinase that plays critical roles in many physiological processes. Recently, Cdk5 has been reported to phosphorylate TRPV1 at threonine 407 (Thr-407) in humans (Thr-406 in rats), which enhances the function of TRPV1 channel and promotes thermal hyperalgesia in the complete Freund's adjuvant (CFA)-induced inflammatory pain rats. However, the underlying mechanisms are still unknown. Here, we demonstrate that Cdk5 phosphorylates TRPV1 at Threonine 406 and promotes the surface localization of TRPV1, leading to inflammatory thermal hyperalgesia. The mutation of Thr-406 of TRPV1 to alanine reduced the interaction of TRPV1 with the cytoskeletal elements and decreased the binding of TRPV1 with the motor protein KIF13B, which led to reduced surface distribution of TRPV1. Disrupting the phosphorylation of TRPV1 at Thr-406 dramatically reduced the surface level of TRPV1 in HEK 293 cells after transient expression and the channel function in cultured dorsal root ganglion (DRG) neurons. Notably, intrathecal administration of the interfering peptide against the phosphorylation of Thr-406 alleviated heat hyperalgesia and reduced the surface level of TRPV1 in inflammatory pain rats. Together, these results demonstrate that Cdk5-mediated phosphorylation of TRPV1 at Thr-406 increases the surface level and the function of TRPV1, while the TAT-T406 peptide can effectively attenuate thermal hyperalgesia. Our studies provide a potential therapy for inflammatory pain. © 2015 Elsevier Inc.

In this paper, an adaptive sliding mode control method is introduced to ensure robust synchronization of two different fractional-order chaotic systems with fully unknown parameters and external disturbances. For this purpose, a fractional integral sliding surface is defined and an adaptive sliding mode controller is designed. In this method, no knowledge of the bounds of parameters and perturbation is required in advance and the parameters are updated through an adaptive control process. The proposed scheme is global and theoretically rigorous. Two examples are given to illustrate effectiveness of the scheme, in which the synchronizations between fractional-order chaotic Chen system and fractional-order chaotic Rössler system, between fractional-order hyperchaotic Lorenz system and fractional-order hyperchaotic Chen system, respectively, are successfully achieved. Corresponding numerical simulations are also given to verify the analytical results. © 2012 Springer Science+Business Media Dordrecht.

This letter investigates the stabilization of three-dimensional fractional-order chaotic systems, and proposes a single state adaptive-feedback controller for fractional-order chaos control based on Lyapunov stability theory, fractional order differential inequality, and adaptive control theory. The present controller which only contains a single state variable is simple both in design and implementation. Simulation results for several fractional-order chaotic systems are provided to illustrate the effectiveness of the proposed scheme. © 2011 Springer Science+Business Media B.V.

Chaotic systems in practice are always influenced by some uncertainties and external disturbances. This paper investigates the problem of practical synchronization of fractional-order chaotic systems. Based on Lyapunov stability theory and a fractional-order differential inequality, a modified adaptive control scheme and adaptive laws of parameters are developed to robustly synchronize coupled fractional-order chaotic systems with unknown parameters and uncertain perturbations. This synchronization approach is simple, global and theoretically rigorous. Simulation results for two fractional-order chaotic systems are provided to illustrate the effectiveness of the proposed scheme. © Springer Science+Business Media B.V. 2011.

A novel method for texture image classification was proposed by using dual-tree complex wavelets transform and support vector machines. The dual-tree complex wavelets transform was used to decompose texture image with four levels, feature vector was first used for training and later on for testing the support vector machine classifier. The experimental setup consists of twenty texture images from the Brodatz image database, results of experimental indicate that the presented method provide superior texture classification accuracy over other methods under the condition of limited training samples, and show the validity and the best generalization ability. © 2014 IEEE.

Mutual information (MI) is always used as the indicator of nonlinear correlation between the variables. The computation of MI can be finished only the continuous-value variables are discretized. In this paper, one new strategy of computing the MI between variables is proposed. The probability density estimation (PDE) is used to determine the density functions in our method. An approximate technology is applied to replace the computation of integral. Finally, MI based on PDE can be obtained. Through the artificially experimental simulations, the performance and rationality of our new method are demonstrated. The experimental results show that our method is feasible, effective and efficient. © 2011 IEEE.

Security of landscape engineering includes ecological security and personal safety. In this paper, two aspects of qualitative risk will be assessed in landscape engineering. In terms of ecological security, it has some major risks which includes department of community stability, soil quality which cannot meet the requirements of plant growth and plant pest disasters. In the process of construction, risks include fall from high-altitude, mechanical injury, electric shock and improper use of pesticides. In response to these security, we raise landscape engineering safety to measure and increase the diversity of plant communities, which emphasis on application of native plant species improve community stability. Plant quarantine, soil testing and other methods are employed to control plant pests and soil quality. Safety training and education and standardize operations are used to ensure the personal safety. © 2015 IEEE.
