Abstract:The intensity and efficiency are two centrally technical indicator of the firewall. The function of state checking of network's fire wall is to check the coming data pack, to judge if those connected entities are accordant with the rule of TCP/IP exchange. Attacks of DoS/DDoS send large numbers of short data packs to firewall in a short time. Those attacks may make firewall's iptables overflow and refuse new connection. The traditional solutions often increase the burden of the firewall. This paper puts a new temporary way to solution this problem in emergent state.

Abstract:The basic characteristic of electric field is that the substance in the field is in operation by the stress. Under steep pulsed electric fields, there is strong distribution of electric fields on the inside and outside surfaces of cell membrane. In virtue of the difference of the permittivity among membrane, cytoplasm and extracellular medium, there must be the electric field stress on the surface of the membrane. The calculation results showe that cell membrane is stressed from two directions of cytoplasm and extracellular medium under external electric fields. The stress on tumor cell membrane is greatly larger than normal cell membrane, so the tumor cell is more sensitive than normal cell. Tumor cell membrane certainly will be destroyed by electric field stress, then its survival environment and germ plasm will be injured and accordingly the cell will be damaged.

Abstract:In order to decrease the consumption of the limited bandwidth resource and the electronic power of mobile battery, fixed paging area strategy is adopted in most mobile communication networks currently. Although its application is very simple, it cannot reach the best performance. In allusion to this problem, we introduce four kinds of improved mobile paging strategies, and analyze their concrete implementation methods briefly. Their performances are compared with fixed paging area strategy. Moreover, the benefits,the drawbacks and the range of application of each scheme are pointed out for future study.

To analyse the characteristic of different synthesis and the major parameters whose variety influence the product. The kinds and ratio of carbon source and catalyst influence the preparation of SWCNTS obviously.The factors such as current and voltage,the kind of inert gases and pressure and the cooling rate of electrodes play important roles in synthesis of SWCNTS by arc discharges. The intensity of laser bean,environmental temperature,the kind and the velocity of flow of catalyst and the frequency and interval of impulse act important parts in SWCNTS produced by laser evaporation. The flow rate of carbon resource, the grain sizes of catalyst,reaction temperature,the gases pressure and flux and matrix materials etc play key parts in SWCNTS synthesized by chemical vapor deposition.

Abstract:A novel coronavirus has been identified as the causative agent of severe acute respiratory syndrome (SARS). The viral main proteinase (M~(pro), also called 3CL~(pro)), controlling the activities of the coronavirus replication complex, represents an attractive target for therapy. A homology model for SARS coronavirus (SARS-CoV) M~(pro), which is based on crystal structures for human coronavirus (strain 229E) M~(pro) and for an inhibitor complex of porcine coronavirus (transmissible gastroenteritis virus, TGEV) M~(pro) are reviewed. The structures reveal a remarkable degree of conservation of the substrate-binding sites, which is further supported by recombinant SARS-CoV M~(pro)-mediated cleavage of a TGEV M~(pro) substrate. Molecular modeling suggests that available rhinovirus 3C~(pro) inhibitors may be modified to make them useful for SARS therapy.

Abstract:Cu is used as the mesosphere material in the experiment, and the diffusion-bonding experiment of Be/Cu/HR-1 stainless steel is made on the Greeble1500 hot stimulation test-machine. The interface characteristics of the diffusion bonding are studied by means of the Scanning Electron-Microscope, the X-ray Diffraction and the HV-1000 Micro-hardness Tester. The results show that Cu can countercheck the mutual diffusion between Be and Fe, as well as the diffusion of Ni and Cr from the stainless steel to Be, resultingly, restrain the formation of the intermetallic compounds among them, but the Be_(2)Cu is formed because of diffusion of Cu, and the intermetallic compounds is firstly formed along grain boundry and distributed as net-like, and the diffusion of elements is made along the grain boundry and their diffusion is non-uniform, and also does not form the layer of the single intermetallic compound. The fracture of the sample lies at the Be/Cu interface area.

The degree of the industrial difference's effects on the level of optimal cooperation and the change of other factor's effect on the level of the optimal cooperation with the change of the industrial difference are analyzed. Some profound results on cooperation are obtained. These results are momentous current significance to explaining some recent economic behavior of Chinese enterprise and leading them to further deepen reform.

Abstract:Project bidding and assessing aim at choosing the best bidder, and then achieve the best optimization of bidder's value aim. The current method of project bidding does not qualifiedly describe the connection among the quality, time limit for the project, and investment of engineering project, so it can not exactly evaluate the bidder's value aim. Consequently, this is not beneficial to achieve the best value. Value engineering is a function analysis method achieving the necessary functions at the lowest cost of total lifetime cycle. Based on the analysis of the existing issues in the valuating system, this paper provides some improvement on the current valuating methods and scientific basis for choosing the best bidder through calculating the value coefficient such as function, cost and value.
