Current Operating Systems and user applications provide several security tools that are designed to automatically handle a set of well-known events and threats, whereas they inform the user that something potentially dangerous is happening an ask her to take a decision. Since we believe that this learning process could have a relevant educational value for children, we present, in this paper, a...

In this article, we present a continuous model for tumor growth . This model describes the evolution of three cellular densities: the density of sane tissue, cancer cells and extracellular medium. In order to render correctly the cellular division, this model use a discrete description of the cell cycle (the set of steps a cell has to undergo in order to divide) presented in [7]. To render cell...

Many programs producing EPS graphics do not allow the inclusion of LATEX commands. While there exist several solutions to work around these difficulties, they all have various drawbacks. (See [1] for a discussion of several methods and an alternative approach to overcome these difficulties.) In this article, we will focus on a particular existing solution, the PSfrag package [2], which provides...

However, this is not always possible, and when a tear becomes chronic or when a subacute tear has poor tissue quality, a graft can facilitate reconstruction. Purpose The primary aim was to evaluate the clinical outcomes of PM reconstruction with dermal allograft augmentation for chronic ...
