Abstract: A part of the pyrazolo[1,5-a]pyridines as novel P13K inhibitors. To build the quantitative structure activity relationships (QSAR) between the molecular structures and the inhibitory activities of 16 compounds, and to further discuss the structural factors that influence activity of compounds. The topological, constitutional, geometrical, electrostatic and quantum-chemical descriptors of 16 compounds were calculated by CODESSA, and these descriptors were preselected with the heuristic method (HM). As a result, the five descriptor linear model was developed to describe the relationship.

Abstract:Two ultra cool different ions are considered as a unique quantum mechanical system in a harmonic trap. The properties of the system are investigated as a model of laser Cooling fluorescence mass analysis. The energy flow between the sample molecular ion and the atomic probe ion through the Coulomb interaction is analyzed as a process of Ferni resonant interaction of different states of the system. Using first order perturbation theory the translational energy efficiency between laser cooling atomic ion and the sample molecular ion is given, accordingly, signal strength distribution of mass spectra relative to mass number of sample molecular ions is discussed.

Li Zhou, Shaohua Chen and Xiao Cheng

¡¡

J. Comput. Sci. Eng. 14 (2014) 514-518 ¡ª Published October 21, 2014

¡¡ Abstract:The quarterly data of 2006-2013 premium income and GDP is used in the paper, using the ADF test and cointegration test and Granger causality test on the relationship between the development of insurance and economic growth in China by empirical analysis and test of the two. The results show that in the sample interval, China insurance development is the Granger cause of economic growth, while promoting economic growth on the development of insurance is not obvious.
¡¡ Keywords:Insurance; GDP; ADF test; Co-integration test; Granger causality test.
