Business Process Modeling Based on Norm  [PDF]
Jun Zhao, Xixia Wang
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.411073
Abstract: As to the question that the current enterprise information system can not adapt quickly to shifting business, this paper mainly studied business process adaptability according to Norm and SOA and proposed a business process modeling method based on Norm. The purpose is to enable business change in the information systems more flexible and better meet the current market and customer demands.
Nondegeneracy of Solution to the Allen-Cahn Equation with Regular Triangle Symmetry  [PDF]
Yong Liu, Jun Wang
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.44017
Abstract:

The Allen-Cahn equation on the plane has a 6-end solution U with regular triangle symmetry. The angle between consecutive nodal lines of U is \"\". We prove in this paper that U is non-degenerated in the class of functions possessing regular triangle symmetry. As an application, we show the existence of a family of solutions close to U.

Scaling Transformation for Nonlocal Interactions  [PDF]
Hai-Jun Wang
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.65073
Abstract: In the light of their relationships with renormalization, in this paper we associate the scaling transformation with nonlocal interactions. On one hand, the association leads us to interpret the nonlocality with locally symmetric method. On the other hand, we find that the nonlocal interaction between hadrons could be test ground for scaling transformation if ascribing the running effects in renormalization to scaling transformation. The nonlocal interaction Lagrangian turns out to vary under scaling transformation, analogous to running cases in renormalization. And the total Lagrangian becomes scale invariant only under some extreme conditions. The conservation law of this extreme Lagrangian is discussed and a contribution named scalum appears to the spin angular momentum. Finally a mechanism is designed to test the scaling effect on nonlocal interaction.

Tingia unita sp. nov. (Noeggerathiales) with strobilus from the Lower Permian of Wuda, Inner Mongolia, China

Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-006-2162-5
Abstract: A number of specimens recently collected from the Early Permian Shanxi Formation of Wuda, Inner Mongolia demonstrate that the leafy shoot and strobilus of Tingia unita sp. nov. are both sprouting from a common stem, and consequently improve our understanding of the whole plant morphology of this enigmatic taxon of the Cathaysian flora. The strobili are cylinder-like, 1.7–2.5 cm in diameter and over 20 cm in length, with a basal stalk 7–8 mm in width and about 7 cm long. Sporophylls are verticillate, with approximately 8–10 in a whorl. On the adaxial side of each sporophyll a sporangium is attached. The strobilus is heterosporous and the microspores are of the Punctatisporites type. Large leaves vary from linear to oblong with entire lateral margins but are slightly lobed at the apex. Small leaves are generally the same as the large leaves but much narrower. The whole plant is probably a small arborescent tree with leafy shoots and strobili forming a crown, rather than a water plant with larger leaves floating on the surface of the water as previously understood. Features of the new species are in favor of the close affinity between Tingia Halle and Noeggerathiales, and accordingly the affinity of Noeggerathiales to Progymnospermophyta.
Discovery of a petrified noeggerathialean strobilus,Discinites sinensis sp. nov. from the Permian of Shizuishan, Ningxia, China

Chinese Science Bulletin , 2000, DOI: 10.1007/BF02887107
Abstract: A petrified strobilusDiscinites sinensis sp. nov. is discovered from the Lower Permian of Shizuishan in Ningxia, North China. The epidermal cells of sporophyll are long and narrow, with both ends pointed. Each sporangium is ellipsoid, with the basal part contracted and short, thick sporangiophore-like. The cells of tapetum and sporangial walls are arranged longitudinally. The annulus is not developed. Mega- and microsporangia are similar in shape. They can hardly be distinguished unless they are broken, and the spores are exposed.In situ mega- and microspores are also similar in shape and both of theDeltoidospora type. The new species supports the systematic placement ofDiscinites within Noeggerathiales, and the progymnosperm affinity of the Noeggerathiales.
A Scheduling Algorithm Based on Communication Delay for Wireless Network Control System
Jun Wang
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: In this study, a scheduling algorithm based on communication delay is proposed. This scheduling algorithm can tolerate delay of periodic communication tasks in wireless network control system. It resolves real-time problem of periodic communication tasks in wireless network control system and partly reduces overtime phenomenon of periodic communication tasks caused by delay in wireless network. At the same time, the nonlinear programming model is built for solving scheduling timetable based on the proposed scheduling algorithm. Finally, the performance of the proposed scheduling algorithm is evaluated by an application example. The statistics results show that it is more effective than traditional scheduling algorithms in wireless network control system.
Effects of Gymnadenia conopsea alcohol extract on collagen synthesis in rat lungs exposed to silica and its mechanism of antioxidative stress

Abstract: Objective: To explore the effects of Gymnadenia conopsea alcohol extract (GcAE) on the collagen synthesis in rat lungs exposed to silica and the influence on antioxidase activities, level of lipid peroxidation (LPO). Methods: One hundred and twenty rats were randomly divided into control group, silica group, and GcAE-treated group. Silicotic animal models were established by direct tracheal instillation of silica into rat lungs surgically. From the second day of model establishment, rats in GcAE-treated group were orally given GcAE [8 g/(kg·d) corresponding to raw herb]. At 7, 14, 21, 28 and 60 days after establishment of the animal model, eight rats in each group were sacrificed, and samples were collected. The malondialdehyde (MDA) content, superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in plasma were assayed by a spectrophotometer. Types Ⅰ and Ⅲ collagen were detected by Sirius red polarization and microscopy, and measuered by Image-Pro Plus Version 4.5 for Windows software. Results: GcAE could reduce the lung/body weight ratio of rats exposed to silica, the synthesis of types ⅠandⅢcollagen of the lungs and the level of lipid peroxidation, increase the activities of SOD and GPx. Conclusion: GcAE can ameliorate the silica-induced pulmonary fibrosis by increasing the activities of antioxidase and alleviating the damage of lipid peroxidation to the lungs.
The Stochastic Ising Model with the Mixed Boundary Conditions
Wang Jun
Boundary Value Problems , 2009,
Abstract: We estimate the spectral gap of the two-dimensional stochastic Ising model for four classes of mixed boundary conditions. On a finite square, in the absence of an external field, two-sided estimates on the spectral gap for the first class of (weak positive) boundary conditions are given. Further, at inverse temperatures , we will show lower bounds of the spectral gap of the Ising model for the other three classes mixed boundary conditions.
