    Threshold model for hot events spreading based on relative impact weight of the user by De-yang ZHANG, Yi-liang HAN, Xiao-long LI, Feng PAN, Yi-xing ZHOU

    Published 2017-09-01
    “…A new relative influence weight function was proposed in combination with the existing linear threshold model.Combining with the information itself sensitivity and the threshold characteristic of the node itself,a threshold model(URLT model) was proposed,which can measure the information communication ability.By simulating the spread of different networks,different sensitivity information and different node thresholds,and comparing the final propagation situation,the experimental results show that the final influence range is consistent with the real spread situation.Therefore,the model has some reference value for the discovery and suppression of the law of information dissemination.…”

    PIDDosome Expression and the Role of Caspase-2 Activation for Chemotherapy-Induced Apoptosis in RCCs by Sebastian Heikaus, Igor Pejin, Helmut Erich Gabbert, Uwe Ramp, Csaba Mahotka

    Published 2010-01-01
    “…Background: The importance of caspase-2 activation for mediating apoptosis in cancer is not clear and seems to differ between different tumour types. Furthermore, only few data have been obtained concerning the expression of caspase-2, which can be alternatively spliced into caspase-2L and caspase-2S, and the other PIDDosome members PIDD and RAIDD in human tumours in vivo. …”

    Analysis of energy consumption of two kinds of edge caching strategies in heterogeneous networks by Yi SUN, Hong WANG, Rongfang SONG

    Published 2018-01-01
    “…The energy consumption of a two-tier heterogeneous network under two different caching strategies was analyzed.Firstly,the energy consumption of each network components was modelled,and the relationship between the energy consumption of heterogeneous networks and the distribution density of small cell,user load per cell and caching capacity was investigated.The simulation results show that edge caching can effectively reduce the energy consumption of heterogeneous networks and the performance of the two caching strategies are different under different density of small base station and user load.Specifically,the energy consumption of both the network and per user under the two caching strategies are reduced with the increase of the density of small base station and the user load per cell,respectively.Furthermore,the influence of small base station’s caching capacity can not be neglected in total energy consumption.…”

    Research on Rainfall Infiltration Characteristics of Loess Slopes Based on Different Rainfall Intensities by GUAN Xiaodi, YAO Yifan

    Published 2023-01-01
    “…In this paper,a homogeneous loess slope in Qingyang,Gansu Province is used as a reference prototype.An indoor model slope that satisfies similar conditions is built.Rainfall infiltration experiments are carried out on the slope under different rainfall intensities,and the corresponding rainfall infiltration rules and scour laws are obtained.The research results show that the rainfall infiltration rate is different at different positions of the slope,which is in descending order of the top,the foot,and the middle of the slope.The rainfall infiltration depth is the largest at the foot of the slope,followed by that at the top of the slope,and the smallest value is observed at the middle of the slope.The rainfall infiltration depth of the slope is 10~15 cm,15~25 cm,18~35 cm,and 20~40 cm in the cases of light rain,moderate rain,heavy rain,and rainstorm,respectively.…”
