A Review Concerned to Research on System Paradigm of Innovation
In the research of innovation, the technique innovation, enterprise innovation, national innovation, and regional innovation, they all can be considered as a system that is made up of a lot of elements and correlation, namely innovation system. Up to the present of the development of innovation theory, the integration, network and systematization have been proved to be a trend of development of innovation theory. The article mainly discusses theory of evolution and the specific characteristics of research on the System Paradigm of innovation. Key words: innovation system; System Paradigm; synergistic evolutio
Dark Energy and Fate of the Universe
We explore the ultimate fate of the Universe by using a divergence-free
parametrization for dark energy .
Unlike the CPL parametrization, this parametrization has well behaved, bounded
behavior for both high redshifts and negative redshifts, and thus can genuinely
cover many theoretical dark energy models. After constraining the parameter
space of this parametrization by using the current cosmological observations,
we find that, at the 95.4% confidence level, our Universe can still exist at
least 16.7 Gyr before it ends in a big rip. Moreover, for the phantom energy
dominated Universe, we find that a gravitationally bound system will be
destroyed at a time , where
is the period of a circular orbit around this system, before the big rip.Comment: 5 pages, 3 figures; typos corrected, publication version, Sci

Evaluation on Integrated Innovation Capability of Regions Based on Principal Component Analysis
The main carriers of national innovation capacity are the regions which gather the technology, economy, and culture, and the strength of regional innovation capacity indicates the strength of the national innovation capability, so the key to the improvement of the national innovation capacity is to enhance the innovation capacity of every region. Using statistics and statistical software SPSS V17.0 Statistics for principal component analysis, and to analyze and sort the innovation capability for our country’s 15 provinces and municipalities, evaluate the results and put forward policy recommendations related, to provide better ideas for economic development of every region.Key words: comprehensive evaluation; innovation capability of regions; integrated innovation capability; principal component analysis The title, abstract and keywords are being translated into French at present and the French version will be added into the paper later
