Land use change is a very complex process of evolution. On the basis of the principle of cellular automata, this article presents a kind of method that we can first mine state transition rule from historical map data, and then conduct forecast by virtue of Monte-Carlo method, achieving spatial...

The opal photonic crystals made of polystyrene microspheres with 155, 230, 270 or 410 nm in diameter were used to enhance upconversion (UC) emission of YF3:Yb3+, Er3+ nanoparticles, respectively. The red or green UC emission of YF3:Yb3+, Er3+ nanoparticles can be selectively enhanced when the...

Earlier studies have shown that Cosmophasis umbratica, a jumping spider from Singapore, is sexually dimorphic in the reflectance of ultraviolet (UV) (males, but not females, have UV-reflecting markings). Here we present the first experimental evidence that the male's UV markings influence mate...

We are surely faced with the unavoidable problem as an element of important restrictions of development of human beings. It must be required to be solved immediately. It also brought the economic concerns to academic fields long ago. The positive and negative impacts of environmental and...

The economy-wide implications of climate change on agricultural sectors in 2050 are estimated using a static computable general equilibrium model. Peculiar to this exercise is the coupling of the economic model with a climatic model forecasting temperature increase in the relevant year and with...

The paper analyses fiscal sustainability of public debt using a dynamic computable general equilibrium model. First, we identify the short-term risk for fiscal stress at country level; second, we investigate the assumption of convergence towards the government debt threshold (medium-term...

This study analyzes and evaluates the status and long-term trend of regional economic sustainability in eastern Anhui Province, China. Based on the triangle model and the definition of economic sustainable development, this study evaluates the interrelationship among regional economic...

We hypothesize that trust plays an important role in affecting the activeness and effectiveness of the global mutual fund industry. Empirically, trust is positively associated with the activeness of domestic funds, whereas for internationals mutual funds conducting cross-border investments...

Most clustering methods assume that the data can be represented by mutually exclusive clusters, although this assumption may not be the case in practice. For example, in gene expression microarray studies, investigators have often found that a gene can play multiple functions in a cell and may,...
