This paper reviews the author's recent works on the basic physics of cold fusion by the TSC (tetrahedral symmetric condensate) theory. Models of TSC formation conditions in condensed matter are first proposed. Secondly formulas for cold fusion rates per D(H)-cluster are explained with typical quantitative results. The 4D/TSC fusion and the 4H/TSC WS fusion are underlying mechanisms, respectively for the D (deuterium)-system and the H (protium)-system. 展开更多

Apart from spontaneous market force, the development of industrial clusters is indispensable from government role in that their development entails the guidance and support from local governments. During the development process, local governments play an extremely important role. On the basis of former research results, the author raises that while developing industrial clusters, local governments should play their important role by formulating a scientific and complete policy supporting system. 展开更多

Industrial cluster has become an important part of regional economy,which status of global industry value chain is critical in the future, Innovation-based Cluster is the industrial cluster theory research at home and abroad made to deepen the difference between the lower part of the Industrial cluster. Promoting innovative industrial cluster formation not only is one of the important means and carrier to cultivate strategic emerging industries, but also an important booster construction of national innovation system. According to the connotation,evolution process and characteristics of the Innovation-based Cluster, This paper from the perspective of three to analysis Innovation-based Clusters' innovative influence factors to find reasonable explanation to the creative industry cluster formation and more in-depth research. 展开更多

Consensus can be achieved under some circumstances. But when the group reach consensus with a convergent opinion value which is not what we expect, how can we intervene the system and change the convergent value? In this paper a mechanism named soft control is first introduced in opinion dynamics to guide the group's opinion when the population are given and evolution rules are not allowed to change. According to the idea of soft control, one or several special agents,called shills, are added and connected to one or several normal agents in the original group. Shills act and are treated as normal agents. The authors prove that the change of convergent opinion value is decided by the initial opinion and influential value of the shill, as well as how the shill connects to normal agents. An interesting and counterintuitive phenomenon is discovered: Adding a shill with an initial opinion value which is smaller(or larger) than the original convergent opinion value dose not necessarily decrease(or increase) the convergent opinion value under some conditions. These conditions are given through mathematical analysis and they are verified by the numerical tests. The authors also find out that the convergence speed of the system varies when a shill is connected to different normal agents. Our simulations show that it is positively related to the degree of the connected normal agent in scale-free networks. 展开更多
