This paper suggests a new methodology based on the Lattice Boltzmann Method for the modelling of complex biomechanical systems. The LBM can be applied for different operations due to the matching of the pixels of medical images with the nodes of the lattice used by the Lattice Boltzmann method. This allows the optimisation and reduction of the computation time when solving multiphysics complex phenomena...
Turning non-autonomic ventricular cells into pacemaking cells is believed to hold the key for making a bio-pacemaker that could potentially treat patients with cardiac conduction diseases. In this article, we analyze the effects of various membrane ion channel currents on ventricular automaticity induced by reducing the inward-rectifier K+ current (IK1). It was found that the L-type calcium current...
This paper studies a delayed singular prey-predator economic model, which is described by differential-algebraic equations due to a economic theory. Local stability and Hopf bifurcation condition are described on the delayed singular prey-predator economic model. It reveals the sensitivity of the model dynamics on gestation time delay. A phenomenon of Hopf bifurcation occurs as the gestation time...
Differential-algebraic bioeconomic systems are a new research field in differential-algebraic systems; there has been little research about bifurcations and fuzzy control of differential-algebraic bioeconomic systems. Bifurcations analysis and feedback controller design of the system offers an important basis for the research of differential-algebraic system theory applied to bioeconomic systems....

Secondly, key technologies involving terrain model optimization, large area database management...
Individual heterogeneity is important information but has not yet been considered in most researches on software outsourcing. This paper makes explicit of individual heterogeneity by using linear mixed model (LMM) based on dataset of Japan software outsourcing. Estimates prove the existence of individual heterogeneity. We also find well-defined and easy-to-monitor software are preferred in Japanese...
3D equipment operation simulation training system (3D-EOSTS) for solving difficult training problem is presented. System building based on 3D modeling can greatly improve the efficiency for the trooppsilas daily training. According to the equipment training requirement, the system architecture and functions are put forward. The whole system includes six simulators such as network simulator, headquarters...
Oversampling is a widely applied sampling method in default risk modeling. Although arbitrarily increased portions of the defaulted in sampling makes logistic estimation more efficiently, it will bring biased estimation results at the same time. We present a simple Bayesian analysis method to derive the offset logistic modeling to correct oversampling bias. It is pointed out that the real value of...
