A concept of generalized discrepancy, which involves pseudodiierential operators to give a criterion of equidistributed pointsets, is developed on the sphere. A simply structured formula in terms of elementary functions is established for the computation of the generalized discrepancy. With the help of this formula ve kinds of point systems on the sphere,(More)
OBJECTIVE The objective of this study was to investigate the effects of the intravenous transplantation of bone marrow mesenchymal stromal cells (BM-MSCs) on the repair of glomerular endothelia and angiogenesis in rats with chronic renal failure (CRF). Furthermore, the mechanism of BM-MSCs promoting angiogenesis was explored by detection of Akt and P-Akt(More)

The Web Service Business Process Execution Language (WS-BPEL, BPEL for short) is now the de facto standard for specifying and executing business process for web service composition and orchestration. As mo- re and more web services are composed using BPEL, the reliability of BPEL process becomes increasingly important. This paper presents a novel approach(More)
In this study, the influence of temperature and light intensity on the growth of seedlings and adults of four species of green tide algae (Ulvaprolifera, Ulvacompressa, Ulva flexuosa and Ulvalinza) from the Yellow Sea was evaluated. The results indicated that the specific growth rate (SGR) of seedlings was much higher than that of adults for the four(More)
The accuracy of geometric structure plays a key role to guarantee high quality of the nano function device and electronic device. In June 1998, the Consultative Committee for Length (CCL) of International Committee for Weights and Measures decided to carry out international comparisons of five different types of artifacts: Step height standards,(More)
The integration of services in heterogeneous, distributed Grid environment is dynamic and diverse because of the disparate resources. Hence, this integration can be technically challenged due to the need of achieving various service when running on different platforms. So, in a Grid environment, implementations of GIS (Geographic Information System) should(More)
