Nonlinear buckling behavior of a complete spherical shell under uniform external pressure and homogenous natural curvature

Matteo Pezzulla

In this work, we consider the stability of a spherical shell under combined loading from a uniform external pressure and a homogenous natural curvature. Nonmechanical stimuli, such as one that tends to modify the rest curvature of an elastic body, are prev ...

Mammalian membrane trafficking as seen through the lens of bacterial toxins

Françoise Gisou van der Goot Grunberg, Francisco De Magalhães Sarmento Ribeiro De Mesquita, Oksana Andrei Sergeeva

A fundamental question of eukaryotic cell biology is how membrane organelles are organised and interact with each other. Cell biologists address these questions by characterising the structural features of membrane compartments and the mechanisms that coor ...
