What determines the number of dominant species in forests?

In this work, the difference in number of dominant species in a community on global scale and successional trajectories was analyzed based on the published data. We explained the reasons of these differ-ences using a resource availability hypothesis, proposed in this work, that the distribution of available resource determined the pattern of commu-nity dominance. The results showed that on global scale the number of dominant species of community varied across latitudinal forest zone, namely from single-species dominance in boreal and temperate forest to multi-species codominance, even no dominant species in tropical forest. This was consistent with the pattern of resource distribution on global scale. Similarly, in successional trajectories, the number of dominant species gradually radiated from single-species dominance to multi-species codominance, even no dominant species in tropical forest. The changing available resources in trajectories were responsible for this difference. By contrary, a community was often dominated by single species in temperate or boreal forest. This was determined by the low available resource, especially low available water and temperature. In boreal forest, low temperature greatly reduced availability of water and nutrient, which were responsible for the single-species dominance. In addition, the conclusion that high available resources sustained low dominance of community might be deduced, based on the fact that the dominance of community declined with the increasing of species diversity. To sum up, the richer the available resources were, the lower the dominance of community was, and vice versa. The hypothesis that the resource availability controlled the dominance of community could well elucidate the difference of community dominance on global and community scale.

CONTROL STRUCTURE AND IMPLEMENTATION OF CELL CONTROL SYSTEM

Cell control system(CCS) plays an important role in the hierarchical control structure of computer integrated manufacturing system(CIMS). It links up workshop controller and CAD/CAPP/CAM down to production facilities, and directly influences flexibility and efficiency of production. The hierarchical control structure and the key technical problems of the CCS are mainly described. The CCS controls the job schedule, the resource allocation and the operation of facilities in the manufacturing procedure according to the production plan and target coming from the workshop controller. The key technologies are discussed in this paper as follows: the application of client/server system structure in the production control and management; production planning and scheduling; the handling of exceptional incidents in production and the DNC interface control as well.

Novel prognostic score for patients with gastric carcinoma

Objective:The lack of a simple criterion for gastric carcinoma creates a persistent challenge for clinicians trying to provide patients with useful prognostic information.The aim of this study was to identify baseline prognostic factors,and use this information to establish a simple criterion to predict outcome in gastric carcinoma.Methods:Between 2005 and 2010, 155 patients with gastric carcinoma,were enrolled.Clinicopathologic prognostic factors were evaluated by univariate and multivariate analysis.Results:Of the 155 patients,48(30.9%)died.Three independent poor prognostic factors were identified by multivariate analysis:gross type>or=3(hazard ratio[HR],1.564;95%CI,1.067 to 2.294),peritoneal dissemination (HR,3.750;95%CI,1.760 to 7.989)and lymphatic duct invasion(HR,3.578;95%CI,1.422 to 9.004).One point was added for each category among three independent prognostic factors.Prognostic score(PS)was determined by an aggregate of these points for each category.There existed a significant difference between survival of patients with PS 0 or 1 and 2(P< 0.0001).Conclusion:Three poor prognostic factors were identified and a simple criteria was devised.Information from this analysis can be used to predict prognosis of gastric carcinoma with a strict stratification.

Coordination of Urbanization and Water Ecological Environment in Shayinghe River Basin,China

During the rapid industrialization and urbanization of China,urban agglomeration in river basin areas raises the problems of over-use of water resources and pollution of the water environment.Related research in China has mainly focused on the conflicts among economic growth,urban expansion and water resource shortages within admin-istrative boundaries.However,water environments are much more dependent on their physical boundaries than their administrative boundaries.Consistent with the nature of water environment,this study aims at analyzing coordination relationships between urban development and water environment changes within physical river basin boundaries.We chose the Shayinghe River Basin,China,as our case study area which is facing serious challenges related to water en-vironment protection.Then we classified 35 county-level administrative units into upstream,midstream and down-stream regions based on their physical characteristics;analyzed the coordination degree of urban agglomeration using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method;and constructed cooperative models using the Linear Programming (LP function) to simulate four scenarios of the coordination relationship be-tween urban population increase and water environment protection based on existing water resources and water pollu-tion data.The results show that the present coordinative situation in Shayinghe River Basin is not sustainable.In gen-eral,more than 50% administrative units are in the bad coordinative situation.In particular,the downstream region is under worse condition than the upstream and midstream regions.Cooperative models in scenario analyses indicate that the population scale set in existing urban master plannings is not coordinated with the water environment protection.To reach the goal of regional sustainable development,the total population needs to be controlled such that it will re-main at 4.5×10 7 or below by 2020 given the capacity of water environment.

Model of Optimal Forest Management Unit Area for a Sustainable Forest Resource Administration

Deforestation is one of the most crucial problems in Indonesia. It creates a number of environmental problems, e.g., landslides, loss of biological diversity, and decrease of carbon sequestration which are impacting human lives, There are a number of underlying causes, often stemmed from the emphasis on a particular forest management objective. Despite numerous forest policies and regulations established by the government, deforestation continues to happen. Quite often, the policies and regulations remain ＂paper tiger＂, which means ineffectual on the ground. One of the contributing factors to deforestation is the lack of custodian for the management of the forests. The regulation, such as law No. 41/1999, stipulates that all state forests must be managed under a FMI3 （forest management unit） as the custodians. The objective of this research is to develop an optimal model for FMU. Using the LGP （linear goal programming）, this research attempts to develop an optimum model for conservation areas. It assumes that the existing zoning approach implemented by the government in conservation areas is inappropriate. The optimum zoning model is expected to improve forest management and restore the forest function as a life supporting system and biological diversity conservation.

A fuzzy logic resource allocation and memory cell pruning based artificial immune recognition system

In order to improve the resource allocation mechanism of artificial immune recognition system(AIRS) and decrease the memory cells,a fuzzy logic resource allocation and memory cell pruning based AIRS(FPAIRS) is proposed.In FPAIRS,the fuzzy logic is determined by a parameter,thus,the optimal fuzzy logics for different problems can be located through changing the parameter value.At the same time,the memory cells of low fitness scores are pruned to improve the classifier.This classifier was compared with other classifiers on six UCI datasets classification performance.The results show that the accuracies reached by FPAIRS are higher than or comparable to the accuracies of other classifiers,and the memory cells decrease when compared with the memory cells of AIRS.The results show that the algorithm is a high-performance classifier.

EFFICIENT ALGORITHMS FOR IDENTIFYING ORTHOLOGOUS SIMPLE SEQUENCE REPEATS OF DISEASE GENES

Dynamic mutations of simple sequence repeats （SSRs） have been demonstrated to affect normal gene function and cause different genetic disorders. Several conserved and even partial functional SSR patterns are discovered in inherited orthologous disease genes. To explore a wide range of SSRs in genetic diseases, a comprehensive system focusing on identifying orthologous SSRs of disease genes through a comparative genomics mechanism is constructed and accomplished by adopting online Mendelian inheritance in man （OMIM） and NCBI HomoloGene databases as the fundamental resources of human genetic diseases and homologous gene information. In addition, an efficient and effective algorithm for searching SSR patterns is also developed for providing annotated SSR information among various model species. By integrating these data resources and mining technologies, biologists and doctors can systematically retrieve novel and important conserved SSR information among orthologous disease genes. The proposed system, Orthologous SSR for Disease Genes （OSDG）, is the first comprehensive framework for identifying orthologous SSRs as potential causative factors of genetic disorders and is freely available at http：//osdg.cs.ntou.edu.tw/.
