CD271 is an imperfect marker for melanoma initiating cells
Oncotarget, 2014 Understanding the molecular and cellular processes underlying melanoma plasticity and heterogeneity is of paramount importance to improve the efficiency of current treatment and to overcome resistance to chemotherapy drugs. The notion of plasticity and heterogeneity implies the existence of melanoma cell populations with different phenotypic and ...

Influence of Initial Imperfections on PMMA Spherical Shell
Advances in Materials Science and Engineering, 2022 This paper focused on the influence of initial imperfection on the critical load of PMMA pressure spherical shell by introducing buckling modes as the initial defect. Four types of pressure spherical shells including complete spherical shell, spherical shell with single penetration, spherical shell with double penetrations, and hyperspherical shell ...

Stability Analysis of Nonlocal Elastic Columns with Initial Imperfection [PDF]
Mathematical Problems in Engineering, 2013 Investigated herein is the postbuckling behavior of an initially imperfect nonlocal elastic column, which is simply supported at one end and subjected to an axial force at the other movable end. The governing nonlinear differential equation of the axially loaded nonlocal elastic column experiencing large deflection is first established within the ...
