“…To extract useful information from the similarity matrix, let us construct from the similarities a network [7][8][9][10][11][12][13][14][15]. A simple fact is that each university is interested in only several universities being most similar with it.…”

“…A simple fact is that each university is interested in only several universities being most similar with it. Accordingly, a strategy called neighbor threshold method is used in this work, namely, we scan all the universities and link every university with a specified number of universities most similar with it [9,12]. If a pair of universities are linked twice by this procedure, we just record the link state and ignore the times.…”

A landscape of a complex system presents a quantitative measure of its global state. The profile of research strength in mainland China is investigated in detail, by which we illustrate a complex network based framework to extract a landscape from detailed records. First, a measure analogous to the Jaccard similarity is proposed to calculate from the presided funds similarities between the top-ranked universities. The neighbor threshold method is employed to reconstruct the similarity network of the universities. Second, the network is divided into communities. In each community the node with the largest degree and the smallest average shortest path length is taken as the representative of the community, called central node. The node bridging each pair of communities is defined to be a boundary. The central nodes and boundaries cooperatively give us a picture of the research strength landscape. Third, the evolutionary behavior is monitored by the fission and fusion probability matrices, elements of which are the percentage of a community at present time that joins into every community at the next time, and the percentage of a community at next time that comes from every present community, respectively. The landscapes in three successive 4-year durations are identified. It was found that some types of universities, such as the medicine&pharmacy and the finance&economy, conserve in single communities in the more than ten years, respectively. The agriculture&forest universities tend to cluster into one community. Meanwhile the engineering type distributes in different communities and tends to mix with the comprehension type. This framework can be used straightforwardly to analyze temporal networks. It provides also a new network-based method for multivariate time series analysis.

“…The algae is the primary producers in the water which is sensitive to environmental changes, can reflect the water quality changes in short time and is widely used in water quality monitoring [1].Lead (Pb) is one of the environmental pollutants, distribution range is wide, with persistent toxic [2].It can inhibit or completely terminate the growth of algae , affect the photosynthetic electron transport system, lead to the decrease of the content of chlorophyll.It makes the distortion of algae cells and changes the types and distribution characteristics of algae in water environment [3].…”

In the Pb2+ stress experiments, the concentrations of Pb2+ were 1, 5, 10, 50, and 80 mg/L respectively, BG11 culture medium was served as the control. The results showed that Pb2+ affected markedly on the growth and physiological characteristics of chlorella pyrenoidosa under certain concentration. As the exposure time, chlorella pyrenoidosa biomass is restrained gradually. Pb2+ also have significant inhibition to effect chlorophyll content and have an effect relationship with the malondialdehyde content of chlorella pyrenoidosa . Lead concentrations and the soluble protein content are time effect relationship . And the longer the inhibitory effect becomes more obvious. Superoxide dismutase (sod) activity increased first then decreased with the increase of the concentration of Pb2+.
