Research and Application of Importance Degree Evaluation Method of Complex Network Cascade Connection Node Based on Load Redistribution
Authors: Zhang Yun Peng
Published: August 2014

This paper presented a model with overload function for cascading failure. The main differences with respect to previous models are as follows: overload function is defined for each node, according to the value of overload function, one node has th ree states: success, overload, failure. After the load decreases, an overloaded node can be success again. The evolution of topology is replaced by the evolution of value of overload function during the process of cascading failure. It’s needless to delete the failure nodes and its edges, the load will avoid the failure nodes automat ically and the decrease of network performance will be reflected by network efficiency. An evaluation method of node importance considering cascading failure is proposed, and its algorithm is presented. A new definition of node importance is proposed. The most important node is the one who see failure results in the largest decrease of networks efficiency at the end of cascading. The evaluation method can help us to find some potential critical nodes which are sensitive to the efficiency of networks but not so important intuitively. Final example verifies its efficiency and feasibility.

Authors: Zhang Jian Nan , Tian Jia Yin , Yang Cheng , Liu Jian Bo
Published: August 2014

The EG scheme also had some shortcomings: the node could not resist attack effectively, and only one routing path was used during the communication. To solve these problems, this scheme proposed to use the multi-path routing to replace the one routing, and the pairwise key was established after the hash function. The connectivity of the system was improved by the multi-path routing, if one routing path was broken, there were also some other alternative paths. Due to the hash function, the attackers could not get any useful information. So the proposed scheme can not only develop the connectivity of the WSNs, but also improve the security of the system.

Authors: Li Yan Hua
Published: August 2014

Using the empirical formula with three free parameters recently proposed, ionization cross sections are given for the representation of cross sections for single ionization of free atoms from the ground stages by electron impact. Almost all experimental results can be approximated by this formula with 20% over the whole energy range between the threshold and 1 . All experimental results can be approximated with experimental error. The formula proposed is not suitable to regenerate the exact contour of fine structure in the ionization cross section curve. The probable error is estimated to be approximately 20%, but the error is larger than 40% and no fine structures are accounted for near the threshold.

Published: August 2014

To understand the influence of vertical dynamics of soil enzyme activities on the active carbon pool in Calamagrostis angustifolia wetland, the vertical distribution in 0-30cm depth of soil cellulase and amylase activities and active organic carbon fractions (microbial biomass carbon /MBC, easily oxidizable carbon/EOC) were measured and the relationship between soil enzyme activities and active organic carbon were analyzed. The results show that the enzyme activities and EOC and MBC contents in topsoil are the greatest. The soil cellulase and amylase activities and EOC and MBC contents show descending trends from surface layer to 30cm. The soil enzyme activities are significantly positive related to EOC and MBC contents. Therefore, with the increase of soil depth, the activities of cellulase and amylase obviously affect the soil active carbon pool. Furthermore, the cellulase activity of marsh soil has the strongest influence on soil active carbon pool.

Authors: Yu Fa Rong , Lian Xiu Zhen , Xie Ming Ren , Li Zuo Ping
Published: August 2014

The present study examined the effects of the immediate stimuli on the levels of catecholamine and single nucleotide of Chinese tree shrew by using RIA approach. When tree shrews were under immediate stimulation, compared to the control animals, the levels of the epinephrine (E), norepinephrine (NE), adenosine monophosphate (cAMP), and cyclic guanosine phosphate (cGMP) in blood were significantly increased. Also, the acute stimulation could significantly enhance the cAMP and cGMP levels of the midbrain ventral tegmental area (VTA), prefrontal cortex (PFC), hippocampus (Hipp), and testis (Testicle), and the dopamine (DA) levels in PFC, Hipp, striatum, and nucleus accumbens (NAc). However, when tree shrews were treated with reserpine, both the E and NE levels were significantly reduced (P< 0.01), indicating that the reserpine interventions could reduce or prevent those stress-related damages. Also, the mitochondrial index (the volume density, surface density and density) in hippocampus cells were significantly increased by 55.21%, 55.21% and 55.21% respectively (P<0.01), compared to those of the control animals housed. Our results demonstrated that the immediate stimulus can significantly affect the synthesis and release of epinephrine, norepinephrine, DA, cMAP, and cGMP in Chinese tree shrews. This study was supported by the following Chinese funding agencies: the National Natural Science Foundation of China (31060283), the National Social Science Fund (07BSH054), the Lanzhou Social Science Fund (07-1-64), and the Academic Innovation Team Building Program Management of Gansu Institute of Political Science and Law (GZF2013CXTD003).

The objective of this study was to investigate the antioxidant capability and preventive effect of probiotics on high fat diet induced oxidative damage. Thirty male rats were randomly divided into three groups.The control group consumed a normal standard diet (5% fat, w:w), the high fat diet group received a high fat diet (20% fat, w:w), and probiotics group received a high fat diet supplemented with 2% probiotics. After 6 weeks, antioxidant capability of liver was determined and DNA fragmentation of liver cell was determined using a comet assay. The results showed that high fat diet could induce oxidative stress, shown as significant increases in lipid peroxidation and nitric oxide free radical, significant decrease in activities of superoxide dismutase and glutathione peroxidase, the percentage of DNA fragmentation was markedly increased, compared with control group. These alterations were significantly reversed in probiotics supplemented group and had no significant difference in antioxidant capability, lipid peroxidation and DNA damage compared with control group. Present observation indicated the probiotics had antioxidant property, which could scavenge free radical and enhance antioxidant defense system, and had the positive protective function on oxidative damage.

In this work, the rheological behavior of uncured natural rubber with different initial moisture contents dried by microwave was studied using RPA under frequency sweep and strain sweep modes. It can be seen from the results that the variation trend of viscous torque S`` versus sweep frequency kept with the trend of elastic torque S` versus sweep frequency. Moreover, the viscous torque S`` values were lower than those for elastic torque S`, a good linear relation curve was obtained by plotting elastic torque S` versus sweep frequency. The curve of storage shear modulus G` versus sweep strain presented a linear relationship, showed a linear viscoelastic behavior of uncured natural rubber with different initial moisture contents. This may be explained by the degradation of molecular chains of natural rubber and the van der waals forces between them.

In order to obtain higher levels of surface form accuracy, it adopted rotational averaging method, analyzed the supporting position and rotation-angle deviation of the model via the finite element analysis technology. You can see that the mirror surface Peak Valley Value and Root Mean Square Value, increase with the increase of supporting and angle deviation. Thus, to realize high precision mirror surface detection, it should guarantee the supporting position and rotation-angle deviation of the model at the same time. The measurement precision of rotational averaging method absolute measurement can achieve one percent wavelength (λ=632.8nm),it is far superior to the other detection technology in absolute measurement.

Published: August 2014

Marine oil spill often forms oil droplets in stormy conditions. Based on the dimensional analysis Rayleigh method, the relationship is established between entrainment rate of oil droplets and statistical physical quantities such as the energy dissipation rate, intrusion depth et al. An expression of size spectrum of oil droplets is derived based on theorem and relationship between the capillary number, the dimensionless intrusion time and viscosity ratio. Preliminary results show that the slope of the derived spectrum is-2.29, which agrees well with the measured slope-2.3 in laboratory. Shear rate, surface tension, droplet radius, oil and water viscosity is the main factors controlling the total number of the oil droplets.
