Invading forces

Space Invading Systems Code

Space Invader is a static analysis tool that aims to perform accurate, automatic verification of the way that programs use pointers. It uses separation logic assertions [10,11] to describe states, and works by performing a proof search, using abstract interpretation to enable convergence. As well as having roots in separation logic, Invader draws on the fundamental work of Sagiv et. al. on shap...

Knock twice before invading

Knock twice before invading eisseria meningitidis , also known as meningococcus, is a pathogen with a nasty habit of forcing normally nonphagocytic endothelial cells to engulf it, allowing the bacterium to penetrate cellular barriers. Hoffmann et al. now demonstrate on page 133 that N. meningitidis activates two distinct signaling pathways in host cells to cause actin cytoskeleton reorganizatio...

p53 cuts off invading cells

In Focus • THE JOURNAL OF CELL BIOLOGY p53 cuts off invading cells T he tumor suppressor p53 does all it can to prevent oncogenes from inducing tumorigenesis, killing defective cells or pushing them into senes-cence. Sometimes, oncogenes manage to initiate tumor development in the presence of p53, but, even then, the tumor suppressor doesn't give up and focuses its efforts instead on limiting t...

Invading the Ideal Free Distribution

Recently, the ideal free dispersal strategy has been proven to be evolutionarily stable in the spatially discrete as well as continuous setting. That is, at equilibrium a species adopting the strategy is immune against invasion by any species carrying a different dispersal strategy, other conditions being held equal. In this paper, we consider a two-species competition model where one of the sp...
