- | * <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

- | *GRNs and vesicles
| |
- | ** Read more about the mechanics of different GRNs (specifically switches).
| |
- | ** Find out how they interact with the external environment.
| |
- | ** Investigate the possiblity of using a different time-step to the fixed one in BSim.
| |
- | ** Investigate the effect of different time steps (GRNs operate on a time scale relatively long compared to that of BSim).
| |
- | ** Investigate the mechanics of our GRNs with respect to vesicle budding and communication.
| |
- | ** Investigate methods for numerically solving stochastic ODEs.
| |
- |
| |
- | *BSim GRNs
| |
- | ** <s>Java implementation of Runge-Kutta 4th order solver.</s> r70
| |
- | *** Refactor ODEs from an [https://2009.igem.org/Team:BCCS-Bristol/Modeling/Antos/ODE_intefaces interface] to an abstract class if necessary.
| |
- | ** <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]
| |
- | ** Implement the solvers into BSim.
| |
- | ** <s>Implement other solvers (more efficient).</s> r70
| |
- | *** The ability to choose between solvers (in BSim, not hard-coded).
| |
- | *** Investigate possibility of using javax/vecmath and matrix ops to maybe make the larger routines more efficient.
| |
- | ** Extend to Stochastic ODEs.
| |
- | ** Interface BSim with external parameters (maybe similar to current parameter files) used to define an ODE system.
| |
- | *** Investigate the feasibility of SBML parameters or a similar XML based format.
| |
- | *** Similarly investigate the format used by XPP (may be more succinct, also is specifically for ODEs).
| |
- | ** Investigate and implement GRN (ODE) and chemical field interaction.
| |
- | *** Study implementation of 3D diffusion in BSim.
| |
- | *** Implement diffusion in/out terms for membrane diffusion.
| |
- | ** GRN interaction with vesicle budding and chemical transport (on the surface of the vesicle and inside it).
| |
- | ** Incorporate a method for seeing the effects of GRN activity (eg colour changes, pop-out time series).
