China is already an important global actor in the fields of research and innovation, and has the potential of becoming a leading force in the next few decades. The shift in Chinas strategy focusing towards R&I and transforming the essence of its economy has been complimented with massive public investments in research and technology. The EU having recognised the leading role China is expected to play, and having adopted a strategic position for becoming a knowledge-based economy, is required to collaborate with China in areas of mutual interest, and for common benefit and prosperity. Moreover for critical global issues which demand close scientific and technological cooperation at an international level, EU has identified in China a natural partner able to contribute and complement its own capacity. The proposed initiative aims to provide support services to European and Chinese researchers, and a flexible platform to facilitate policy discussions between European and Chinese stakeholders. Moreover, DRAGON-STARPLUS will provide the EC and the Member States with a toolset for setting a long term cooperation strategy in research and innovation with China. The project aims to provide efficient services on three levels (priority areas): - Support the European and Chinese research communities to establish collaborations under Horizon 2020 and beyond. -Provide a cooperation platform and tools to policy makers, aiming ultimately to support and enhance the bilateral cooperation, through the concept of mutual benefit. -Provide an ERA-NET style platform to funding agencies for exchanging best practices and planning joint activities. The proposed activities take into account the current on-going policy dialogue and the peculiarities of the research and innovation environment in China, and are based upon the outputs and the established mechanisms of the previous DRAGON-STAR project, as well as upon the sound results of previous related projects (e.g. OPEN-ICT, CO-REACH).

With the help of the similarity transformation connected the variable-coefficient nonlinear Schrödinger equation with the standard nonlinear Schrödinger equation, we firstly obtain first-order and second-order rogue wave solutions in two dimensional graded-index waveguides. Then, we investigate the nonlinear tunneling of controllable rogue waves when they pass through nonlinear barrier and nonlinear well. Our results indicate that the propagation behaviors of rogue waves, such as postpone, sustainment and restraint, can be manipulated by choosing the relation between the maximum value of the effective propagation distance Z m and the effective propagation distance corresponding to maximum amplitude of rogue waves Z 0. Postponed, sustained and restrained rogue waves can tunnel through the nonlinear barrier or well with increasing, unchanged and decreasing amplitudes by modulating the ratio of the amplitudes of rogue waves to barrier or well height. © 2013 Springer Science+Business Media Dordrecht.

In the standard approach to cosmological modeling in the framework of general relativity, the energy conditions play an important role in the understanding of several properties of the Universe, including singularity theorems, the current accelerating expansion phase, and the possible existence of the so-called phantom fields. Recently, the f(T) gravity has been invoked as an alternative approach for explaining the observed acceleration expansion of the Universe. If gravity is described by a f(T) theory instead of general relativity, there are a number of issues that ought to be reexamined in the framework of f(T) theories. In this work, to proceed further with the current investigation of the limits and potentialities of the f(T) gravity theories, we derive and discuss the bounds imposed by the energy conditions on a general f(T) functional form. The null and strong energy conditions in the framework of f(T) gravity are derived from first principles, namely the purely geometric Raychaudhuri equation along with the requirement that gravity is attractive. The weak and dominant energy conditions are then obtained in a direct approach via an effective energy-momentum tensor for f(T) gravity. Although similar, the energy condition inequalities are different from those of general relativity, but in the limit f(T)=T, the standard forms for the energy conditions in general relativity are recovered. As a concrete application of the derived energy conditions to locally homogeneous and isotropic f(T) cosmology, we use the recent estimated value of the Hubble parameter to set bounds from the weak energy condition on the parameters of two specific families of f(T) gravity theories. © 2012 American Physical Society.

In this paper, we investigate the non-Markovian dynamics of a model to mimic the excitation energy transfer (EET) between chromophores in photosynthesis systems. The numerical path integral method is used. This method includes the non-Markovian effects of the environmental affects, and it does not need the perturbation approximation in solving the dynamics of systems of interest. It implies that the coherence helps the EET between chromophores through lasting the transfer time rather than enhancing the transfer rate of the EET. In particular, the non-Markovian environment greatly increases the efficiency of the EET in the photosynthesis systems. © 2010 The American Physical Society. Source

Current energy designs for a building in China focus on the energy efficiency of the whole building and thus often neglect the energy difference between different housing units in apartment buildings. The best design technique in terms of energy savings is not only to decrease whole building energy demand, but also to reduce the energy difference between different housing units to a relatively low level. This paper introduces an important index "energy performance difference between housing units" (EDH) to evaluate the drawbacks of conventional designs on a typical residential building in hot summer and cold winter zone. Then nine improved design options were considered as the possible strategies to diminish the EDH, based on a number of building simulations with the program DeST-h. Results show that the option 9 (add movable shading for the east facing windows and west facing windows, and reduce the U-values of the east walls and west facing windows), an improved design strategy according to the EDH of the current design, reduces the EDH to less than 4% that is much lower than other options and meanwhile ensures a decrease in whole building energy demands. A case study was carried out to validate the effectiveness of this index in optimization. As a conclusion, EDH is a very useful index for optimizing energy designs of apartment buildings and can be used in China to improve conventional building designs. © 2012 Elsevier Ltd. Source
