Based on a non-competitive input-output model capturing China’s processing exports, this paper establishes a goal programming model to optimize China’s export structure. In this model, China’s domestic production is divided into three parts: Production for domestic use, processing exports, and non-processing exports and production for other foreign invested enterprises. This division enables di...

We present an approach for process conceptualization in hillslope hydrology. We develop and implement a series of virtual experiments, whereby the interaction between water flow pathways, source and mixing at the hillslope scale is examined within a virtual experiment framework. We define these virtual experiments as ‘numerical experiments with a model driven by collective field intelligence’. ...

foreign direct investment (fdi) plays a crucial role in the economic literature, especially in developing countries. it is also an important factor for policy makers to analyze the relation between foreign direct investment and other important economic variables. one of these variables is export which is always mentioned in iran's economic development programs. in this study, the relation betwe...

BACKGROUND The AIDS and Cancer Specimen Resource (ACSR) is an HIV/AIDS tissue bank consortium sponsored by the National Cancer Institute (NCI) Division of Cancer Treatment and Diagnosis (DCTD). The ACSR offers to approved researchers HIV infected biologic samples and uninfected control tissues including tissue cores in micro-arrays (TMA) accompanied by de-identified clinical data. Researchers i...

Limited and uneven distributed water resources have become one of the main obstacles to China's sustainable development, “virtual hypothesis” (VWH) is expected help mitigate stress. This study discusses virtual transfer pattern stress in China from VWH perspective. Economic sectors are divided into land-dependent non-land-dependent according their dependence on specific local land types. Furthe...

[1] Surface waters of the Arctic Ocean have the highest concentrations of dissolved organic carbon (DOC) and terrigenous dissolved organic matter (DOM) of all ocean basins. Concentrations of dissolved lignin phenols in polar surface waters are 7-fold to 16-fold higher than those in the Atlantic and Pacific oceans, and stable carbon isotopic compositions of DOM are depleted in C by 1–2% relative...
