    The anti-sigma factor TcdC modulates hypervirulence in an epidemic BI/NAP1/027 clinical isolate of Clostridium difficile. by Glen P Carter, Gillian R Douce, Revathi Govind, Pauline M Howarth, Kate E Mackin, Janice Spencer, Anthony M Buckley, Ana Antunes, Despina Kotsanas, Grant A Jenkin, Bruno Dupuy, Julian I Rood, Dena Lyras

    Published 2011-10-01
    “…This study provides evidence that a naturally occurring mutation in a negative regulator of toxin production, the anti-sigma factor TcdC, is an important factor in the development of hypervirulence in epidemic C. difficile isolates, presumably because the mutation leads to significantly increased toxin production, a contentious hypothesis until now. …”

    Analysis of Water and Sediment Characteristics in Rongjiang River Basin by AO Liangting

    Published 2023-01-01
    “…The Rongjiang River Basin is a tidal reach,where the movement of water and sediment is complicated.Over the years,sediment deposition and soil erosion are serious.Hence,the study of the variations of water and sediment in the Rongjiang River Basin is of great significance for water area management and river management in the basin.Upon the comprehensive analysis of the water and sediment data of Dongqiaoyuan Hydrological Station in the mainstream of Rongjiang River from 1953 to 2017,the trend analysis of the water and sediment sequence is carried out by the moving average method and Mann-Kendall trend test.The mutation analysis is made by the Mann-Kendall mutation test and ordered cluster analysis.Meanwhile,Morlet wavelet analysis is used to discuss the periodicity of the water and sediment process.The characteristics,variations,and influencing factors of water and sediment in the Rongjiang River Basin are obtained to provide theoretical support and a digital model for further study of the characteristics of water and sediment in the basin.…”

    Bayesian network structure learning algorithm based on hybrid binary salp swarm-differential evolution algorithm by Bin LIU, Ruixing FAN, Haoran LIU, Liyue ZHANG, Haiyu WANG, Chunlan ZHANG

    Published 2019-07-01
    “…Aiming at the disadvantages of Bayesian network structure learned by heuristic algorithms,which were trapping in local minimums and having low search efficiency,a method of learning Bayesian network structure based on hybrid binary slap swarm-differential evolution algorithm was proposed.An adaptive scale factor was used to balance local and global search in the swarm grouping stage.The improved mutation operator and crossover operator were taken into salp search strategy and differential search strategy respectively to renew different subswarms in the update stage.Two-point mutation operator was adopted to improve the swarm’s diversity in the stage of merging of subswarms.The convergence analysis of the proposed algorithm demonstrates that best structure can be found through the iterative search of population.Experimental results show that the convergence accuracy and efficiency of the proposed algorithm are improved compared with other algorithms.…”
