    Changes in the stiffness of human mesenchymal stem cells with the progress of cell death as measured by atomic force microscopy by Nikolay Nikolaev, Torsten Muller, David Williams, Yang Liu

    Published 2013
    “…This note reports observations of the change of stiffness of human mesenchymal stem cells (hMSCs) with the progress of cell death as measured by AFM. hMSC with impaired membrane, dead and viable cells were labelled with Annexin V and Propidium Iodide after 24 h cold storage, followed by AFM measurement and Young's modulus of cells was derived. Viable hMSCs have a Young's modulus (E) in the range of 0.81-1.13 kPa and consistent measurement was observed when different measurement locations were chosen. …”

    Rough path properties for local time of symmetric α stable process by Qingfeng Wang, Huaizhong Zhao

    Published 2017
    “…In this paper, we first prove that the local time associated with symmetric α-stable processes is of bounded p-variation for any View the MathML source partly based on Barlow’s estimation of the modulus of the local time of such processes. The fact that the local time is of bounded p-variation for any View the MathML source enables us to define the integral of the local time View the MathML source as a Young integral for less smooth functions being of bounded q-variation with View the MathML source. …”
