    The Nonlinear Stability Prediction and FEM Modeling of High-Speed Spindle System with Joints Dynamic Characteristics by Bo Wang, Wei Sun, Kunpeng Xu, Junyong Zhang, Bangchun Wen

    Published 2014-01-01
    “…In this paper, the distribution spring model of spindle-holder-tool joints was built with the consideration of its dynamic characteristics; the five-DOF dynamic model of the angle contact ball bearing was also established to study the influence of speed and preload on the spindle-bearing joint, both of which were used in the general whole complete spindle system FEM model. The rationality of the model was verified by comparison with the FRF of traditional rigid model and experiments. …”

    The Fem cell-surface signaling system is regulated by ExsA in Pseudomonas aeruginosa and affects pathogenicity by Yanqi Li, Anjali Bhagirath, Sara Badr, Pansong Zhang, Lin Chen, Maryam Dadashi, Michael G. Surette, Kangmin Duan

    Published 2025-01-01
    “…Summary: Bacterial interspecies interactions shape microbial communities and influence the progression of polymicrobial infections. FemI-FemR-FemA, a cell-surface signaling system, in Pseudomonas aeruginosa, is involved in the uptake of iron-chelating mycobactin produced by Mycobacterium spp. …”
