This paper studies an inverse problem of recovering the first-order coefficient in parabolic equation when the final observation is given. Such problem has important application in a large field of applied science. The original problem is transformed into an optimal control problem by the...

With global climate change, the extreme flood disasters which are characterized with low frequency but huge economic losses occur more frequently. The management of the extreme flood disasters mainly depends on the administrative means of the governments at all levels in China. When the extreme...

We estimate the labor market consequences of corporate diversification using worker-firm matched data from the U.S. Census Bureau. We find evidence that workers in diversified firms have greater cross-industry mobility. Displaced workers experience significantly smaller losses when they move to...

We propose serial correlation robust asymptotic confidence bands for the receiver operating characteristic (ROC) curves estimated by quasi-maximum likelihood in the binormal model. Our simulation experiments confirm that this new method performs fairly well in finite samples. The conventional...

A sequential grouping heuristic (SGH) that supports parallel computing is presented for solving the two-dimensional cutting stock problem with pattern reduction, where a set of rectangular items with given demand are cut from rectangular stock plates of the same size, considering both...

Inventory managers often group inventory items into classes to manage and control them more efficiently. The well-known ABC inventory classification approach categorizes inventory items into A, B and C classes according to their sales and usage volume. In this paper, we present an optimization...

Cross-sectional analysis is problematic when examining the determinants of migration as well as its impacts. Panel data may potentially solve the problem by tracking households over different time periods. Using panel data from household surveys in six provinces in rural China over 1986 to 1999,...

Based on a five-letter model of the 20 amino acids, we propose a new 3-D graphical representation of protein sequence. Then we derive from the graphical representation, numerical indices called 3-D coupling numbers, to characterize protein sequences. The examination of the...

This passage mainly deals with the problem of why different transition countries have different transition mode and different economic performance. According to this research, it has been found that the economic system of the traditional socialist countries played an important role in their...

The pricing issue of supply chain options is generally considered in the Stackelberg game framework in the literature. Such a pricing scheme, however, is usually unacceptable to the follower in the game since it serves only the leader's interest. Different from the existing literature, we...
