NiTi alloy exhibits superior superelastic properties but its wide application is limited by its poor workability. In this study, Ni-rich NiTi wire was used as the feedstock and a wall-shaped NiTi component with height of 130mm was deposited on Ti substrate by cold metal transfer (CMT) based wire...

Tankov (2011) improves the Fréchet bounds for a bivariate copula when its values on a compact subset of the unit square are given. He shows that the best possible bounds are quasi-copulas and gives a sufficient condition for these bounds to be copulas. In this note we give weaker sufficient...

The impact of hydraulic engineering works and human activities on hydrology has become a hot issue along with the economy and social development. The water cycle model of the upper reaches of the Yangtze River (URYR) is established based on the improved Soil and Water Assessment Tool (SWAT)...

We conduct an input--output analysis of China's employment changes due to changes in trade structure on a sectoral level. We find that between 2002 and 2007 China generated about 71 million jobs due to trade expansion. We also estimate the additional amount of trade that would be needed if China...

In conventional economic theories, population is determined outside of the economic system. However, classical political economists such as Adam Smith and Thomas Malthus have long argued for the endogenous determination of population, hence establishing a connection between economics and...
