A high-pressure fixed bed reactor was used to study the formation condition of K2CO3·1.5H2O and the significance of K2CO3·1.5H2O in reducing the regeneration energy required for potassium-based sorbents. The reaction heat of K2CO3 converted into KHCO3 in the following reaction:...

It seems a universal phenomenon of networks that the attacks on a small number of nodes by an adversary player Alice may generate a global cascading failure of the networks. It has been shown (Li et al., 2013) that classic scale-free networks (Barabási and Albert, 1999, Barabási, 2009) are...

This paper compares the productivity and efficiency of large banks and community banks in the United States over the period 1997–2006. This comparison is performed by estimating a true random effects stochastic distance frontier model—a model that is capable of disentangling unobserved...

The 2013 World Trade Organization ministerial in Bali produced a comprehensive framework agreement on trade facilitation. If fully implemented, the agreement should increase the speed and reduce the cost of moving goods across international borders. But which reforms are most likely to improve...

The stochastic frontier model used for continuous dependent variables is extended to accommodate output measured as a discrete ordinal outcome variable. Conditional on the inefficiency error, the assumptions of the ordered probit model are adopted for the log of output. Bayesian estimation...
