Line of Investigation
Our main line of investigation uses unconventional computing as a means of building novel computing paradigms, such as in biology, physics and chemistry.
We are attempting to construct discrete dynamical systems capable of simulating cellular computation. Therefore, our work focuses on molecular computation. We thus have three models using cellular automata theory (you can see our original contributions [http://uncomp.uwe.ac.uk/genaro/ click here]).
Cellular automata (CA) operate over a scales ranging from the molecular level to n-dimensions and are massively parallel. Also, they are capable of supporting universal computation, self-repair and self-reproduction.
We wish contribute to the iGEM project development various protein based bio-components. We will work along three main lines: complex and reversible dynamical systems and formal languages, that support particles and multiple reactions, related to the molecular transformations.
We aim to develop CA software for a specific bio-simulation and gradually implement broader real biological scenarios.
iGEM México Project
EXPERIMENT PROPOSAL: Engineering a genetic signaling cascade to produce a green flourescence protein expression/repression system in Escherichia coli.
IN THIS PART OF THE PROJECT: We intend to emulate some genetic networks already identified in Arabidopsis responsible for the formation of hair in root and leaves. These networks lead to simple genetic circuits of the repression/expression type. We would like to show that these systems support Turing patterns.
MODELLING PROPOSAL: Developing models to describe inside-the-cell metabolic events
through a cellular automata approach.
We study two-dimensional cellular automaton, where every cell takes states 0 and 1 and updates its state depending on sum of states of its 8 closest neighbors as follows. Cell in state 0 takes state 1 if there are exactly two neighbors in state 1, otherwise the cell remains in state
0. Cell in state 1 remains in state 1 if there are exactly seven neighbors in state 1, otherwise the cell switches to state 0. CA governed by such cell-state transition rule exhibits reaction-diffusion like pattern dynamics, so we call this Diffusion Rule.
Using the diffusion rule we can generate a dynamical pattern over a system, like turn on/off
ligth with alive o dead cells that shows a luminescence, examples include fluorescence,
bioluminescence and phosphorescence.
Starting with any configuration, the cells alive are represented in yellow (the activator) and dead in black (the inhibitor), see figure 4. The system is created defining an inicial state over the base configuration (see figure 3). The luminescence is obtained by the evolution of this initial pattern.
