Títol: Searching for all gene networks capable of pattern formation.
Resum: Development is the process by which the complex anatomy of multicellular organisms is built in each generation. Not many other natural processes lead to so much complexity in such a short period of time.
Morphological transformations during development are regulated by what we call gene regulatory networks, that is, the specific activatory and inhibitory interactions between gene products at a molecular level. In this talk, under the framework of reaction-diffusion models, we attempt a mathematical approach to these developmental transformations by asking ourselves a very simple question: “which gene regulatory networks are actually capable of pattern formation?” More specifically, we wonder whether the immense number of patterning gene networks that we can think of – especially when the number of genes involved in the network is very large – can all be sorted into some few fundamental classes sharing the same topological features and resulting in similar final patterns.

and bitwise operators, e.g. 
. State-of-the-art software protection mechanisms leverage MBA semantics-preserving transformations to obfuscate code. This possibility is motivated by the fact that the combination of operators from these different fields do not interact well together. Moreover, computer algebra systems do not support bitwise operators with symbolic variables (let alone combining them with arithmetic expressions).
