Stability and Hopf Bifurcation in a Three-Component Planktonic Model with Spatial Diffusion and Time Delay

Abstract: Due to the different roles that nontoxic phytoplankton and toxin-producing phytoplankton play in the whole aquatic system, a delayed reaction-diffusion planktonic model under homogeneous Neumann boundary condition is investigated theoretically and numerically This model describes the interactions between the zooplankton and two kinds of phytoplanktons The long-time behavior of the model and existence of positive constant equilibrium solution are first discussed Then, the stability of constant equilibrium solution and occurrence of Hopf bifurcation are detailed and analyzed by using the bifurcation theory Moreover, the formulas for determining the bifurcation direction and stability of spatially bifurcating solutions are derived Finally, some numerical simulations are performed to verify the appearance of the spatially homogeneous and nonhomogeneous periodic solutions

Research on Revenue Insurance Premium Ratemaking of Jujube Based on Copula-Stochastic Optimization Model

Abstract: During the process of jujube planting, there are not only natural risks caused by natural disasters but also market risks caused by price factors. In the study, firstly, wavelet analysis method was used to stabilize the jujube yield per unit area and the jujube price from 1997 to 2018 in Aksu region, Xinjiang, China. Secondly, EasyFit software was used to fit the distribution functions of yield per unit area and price, respectively. Thirdly, the optimal Copula function which connects the marginal distribution functions and its joint distribution function was selected with the principle of “the minimum square distance from the empirical Copula function.” Finally, taking the premium rate and the insurance amount as two decision variables, the farmer’s risk minimization as the objective function, around the four constraints of functions and role of insurance, the nonspeculative nature of insurance, the sustainability of insurance, and the moral hazard factors and the farmers’ willing to participate in insurance, the Copula-stochastic optimization model was set up to determine the premium rate of jujube revenue insurance in Aksu region.

Does Stock Option Plan Induce Over-Investment? Evidence from Listed Companies of Manufacturing on SME Board Market in China

Abstract: Based on the sample of 257 listed companies of manufacturing industry on small-and-medium enterprise(SME) board market from 2005 to 2011,we examine whether implementing stock option plan will reduce the chance of over-investment and magnitude of executives' agency cost.We prove that the SME listed companies with a stock option plan are more likely to over-invest and the proportion of over-investment will result in a positive collection with free cash flows,at the same time,we also find that no evidence proves SME listed companies with stock option plan reduce the agency cost significantly.

Preconcerted wormhole routing algorithm for Mesh structure based on the network on chip

Abstract: In order to avoid the deadlock, congestion and high transmission delay of network on chip in the process of data exchange, this paper proposed a kind of preconcerted wormhole routing solution. First, the author put forward this idea based on the VC technology and wormhole routing technology. Secondly, design the Router structure, a flit format and the flit routing process according to the algorithm thought. Then, complete the algorithm based on the previous studies. Finally, simulate and apply this routing algorithm to the NoC of MESH topology structure by the NIRGAM simulator. The test results show that compared with the routing algorithms of XY, Odd-even, AntNet, the program in this paper has a lower average transmission delay under the premise of high-throughput rate.

Air quality effect on the hotel industry

Abstract: This article makes an original contribution to the hospitality research literature. It proposes a curvilinear impact of air quality (AQ) on hotel sales (HS) and then empirically tests this nonlinea...
