- | "Growth curves were measured for all of the mutants, and their log-phase doubling times were calculated. In general, more extreme vesiculation phenotypes corresponded to longer doubling times" (Outer Membrane Vesicle Production by Escherichia coli Is Independent of Membrane Instability)

- | * <s>Issue with bacteria 'escaping' the boundaries</s> r61
| |
- | ** When the bacteria have a large enough force and the time step is not small enough the bacteris are able to 'escape' the boundary.
| |
- | ** Fix this by checking the distance and direction of all the bacteria close to the boundary. This will catch those that have crossed the boundary in one time step.
| |
- | ** THIS COULD BE IMPROVED FURTHER - it allows for far greater forces however does not fix this problem in all cases.
| |
- |
| |
- | * <s>Understand how bacteria "tumble" under magnetic force</s>
| |
- | ** It is believed that the magnetic force causes the bacteria to orientate in line with the field and so the tumble phase will not occur.
| |
- |
| |
- | * Implement directed bateria (bacteria under constant magnetic field)
| |
- | ** <s>Control only the direction of the bacteria - not the force.</s> r116
| |
- | ** Add some variation in the direction of each bacterium
| |
- | *** The average alignment of the population is described by Langevin function for classical paramagnetism. [http://arjournals.annualreviews.org/doi/pdf/10.1146/annurev.mi.36.100182.001245]
| |
- | *** The interaction of the population with a magnetic field is affected by the temperature.
| |
- |
| |
- | * Finish coding the magnetic force for variable magnetic force
| |
- | ** <s>Code the magnetic force as an additional force on the bacteria along with the internal and external forces.</s> r82
| |
- | ** Find realistic values for the magnetic force acting on the bacteria.
| |
- |
| |
- | * Code half-coated bead
| |
- | ** Apply two different potentials to each half of the bead - one side has a potential well (the bacteria attach here) and the other side has no well (the bacteria will interact normally here).
| |
- |
| |
- | * Control which objects are affected by the magnetic force
| |
- | ** Magnetotactic bacteria in a constant magnetic field
| |
- | ** Magnetotactic bacteria in a variable magnetic field
| |
- | ** E. coli attaching to a magnetic bead under a variable magnetic field

- | ** <s>Proof of concept to check functionality.</s> [http://www.pnas.org/content/101/30/10955 Something like this]
| |
- | *** Update: it works! (r140) Need to run large scale simulation to check for long term synchronization...
| |
- | *** Compare chemical field with degradation to vesicular transport.
| |
- | *** <s>Refactor ODEs from an interface to an abstract class if necessary.</s> EDIT: [https://2009.igem.org/Team:BCCS-Bristol/Modeling/Antos/ODE_intefaces interface] seems sufficient so far, however need to generalise ODEs to just one interface.
| |
- | ** <s>Investigate other options in terms of external libraries (eg odeToJava - good but seems overcomplicated for current purposes; hundreds of lines of code for one solver routine)</s>[https://2009.igem.org/Team:BCCS-Bristol/Modeling/Antos#ODE_Solvers_and_Libraries_already_in_existence done]
| |
- | ** Extend to Stochastic ODEs. However, how much stochasticity is inherent in our system? autoinducer chemical field is intrinsically random due to motion of bacteria.

| |
- | *GRNs and vesicles

- | ** Read more about the mechanics switch, bistable and 'counter' GRNs and methods of modelling them.
| |
- | ** Investigate the mechanics of our GRNs with respect to vesicle budding and communication.
| |
- | ** Investigate methods for numerically solving stochastic ODEs.
