    Investigating the formation and evolution of plant diversity patterns in the Qiangtang Plateau based on phylofloristics approach by Xiaoping Li, Yun Han, Lei Miao, Hao Xu, Jingya Yu, Shuang Han, Faqi Zhang

    Published 2025-04-01
    “…Furthermore, using fossil data, we deduced that the emergence of seed plant families in this region dates back to the Cretaceous period (145.00 Ma), with a significant acceleration in evolutionary rates observed since the onset of the Quaternary Ice Age (2.00 Ma). These findings underscore the pivotal role of the uplift of the Qiangtang Plateau and the climatic shifts during the Quaternary Ice Age as primary drivers shaping the region's contemporary distribution patterns of alpine plants.…”

    Partial fanout multicast switching model of reconfigurable foundation network by Bo ZHANG, Bin-qiang WANG, Sheng-ping ZHU

    Published 2012-05-01
    “…The multicast switching model using copying before scheduling and fanout copying modes had worse large-scale extensibility capability in traditional technology system.A partial fanout multicast switching model with basic switching fabric comprised by 2×2 Boolean cells and Boolean group concentrators was proposed facing to reconfigurable foundation network.Self-routing path selected was realized by partial fanout copying mode and quaternary symbols cut-through coding.Unicast blocking probability,multicast blocking probability and multicast fanout ratio iterative course was deduced based on unicast and multicast mixed business source.The simulation result shows that the value of multicast blocking probability is from 10<sup>-10</sup> to 10<sup>-2</sup> based on Bernoulli uniform business source when normalized unicast load 0.2,the model can meet time QoS requirement because the value of multicast time delay is less than hundred nano-second level limit.…”

    Study of the Sediment Pollutant Evaluation and Resource Utilization in the North Canal by YAN Yulin

    Published 2020-01-01
    “…To understand the physical properties and pollution degree of the sediment in the North Canal,this paper collects the sediment in sections of North Canal with a columnar sampling device,and determines the physical properties,nutrient salt and heavy metal content of sediment.The results indicate that the average value of organic matter,TN and TP were 30.39 g/kg,0.161% and 0.174%,respectively,and were primary section, tertiary section and quaternary section according to the evaluation criterion.The average value of Cd,Cr,Ni,Zn,Cu,Pb and As were 0.39、86.55、29.09、199.82、52.27、33.86 and 8.26 mg/kg,respectively,which exceeded the background values for soil in Beijing.The evaluation results of geo-accumulation index show that the upper reach was partial moderate pollution,among which Cd and Zn were moderate pollution,and the middle and lower reaches were mild pollution.The average content of heavy metals was below the light pollution,so the pollution is not serious.Besides,the sediment can be reused to agricultural land and used as levee material,which exploit the way of resource utilization.…”
