Pervasive mobility and an exponential increase in the number of connected devices are adding to IT complexity. Users are bypassing traditional IT to access cloud-based services. Boundaries between computing systems, people, and things are disappearing. New approaches are required to manage today’s and tomorrow’s increasingly connected and heterogeneous ecosystems of people, computing processes,...

Various models of tumor growth are available in the litterature. A first class describes the evolution of the cell number density when considered as a continuous visco-elastic material with growth. A second class, describes the tumor as a set and rules for the free boundary are given related to the classical Hele-Shaw model of fluid dynamics. Following the lines of previous papers where the mat...

The Young's modulus E of ice is an important parameter in models of tidal deformation [1, e.g] and in converting flexural rigidities to ice shell thicknesses [2, e.g.]. There is a disagreement of an order of magnitude between measurements of E in the laboratory (9 GPa) and from field observations (≈1 GPa). Here I use a simple yielding model to address this discrepancy, and conclude that E = 9 G...
