Let's read the reference papers above this weekend and discuss what exactly we should measure at the next meeting. The next meeting will be at 02:30pm on Monday 06/16/2014 (after my tutorial[http://tuvalu.santafe.edu/events/workshops/index.php/Complex_Systems_Summer_School_2014-Tutorials#Tutorial:_Rotors.2C_Spirals_and_Scroll_Waves]) in the lecture hall. If you have any questions I will be around this weekend. You will most certainly find me in the student lounge (or wherever TV is available) at 7pm on Saturday 06/14/2014 for FIFA World Cup Japan vs. Côte d'Ivoire | Let's read the reference papers above this weekend and discuss what exactly we should measure at the next meeting.

Thank you for your interest in our project. Please join us any time and share your thoughts!
06/12/2014 Brainstorming Session
Why: To identify adaptive mechanisms leading to cardiac arrhythmia in diseased hearts. Then localize the origin of arrhythmia (= wavebreak) and treat it before it happens.
Hypothesis: Arrhythmias result from an adaptive mechanism to optimize information transmission in abnormal hearts.
Challenge: Wavebreaks can occur in normal heart tissue.
How: Time series from a cellular automata model of the 2-D heart tissue. ?Time series of invasive electrogram from animal or human
What: To quantify information transmission within the heart
Potential Metrics
Mutual information - Calculate mutual information of two separate locations from binary time series (0–resting, 1–excited). A high mutual information suggests electrical coupling.
Permutation Entropy - Temporal uncertainty
Transfer Entropy - Spatial uncertainty

Let's read the reference papers above this weekend and discuss what exactly we should measure at the next meeting. The next meeting will be at 02:30pm on Monday 06/16/2014 (after my tutorial[1]) in the lecture hall. If you have any questions I will be around this weekend. You will most certainly find me in the student lounge (or wherever TV is available) at 7pm on Saturday 06/14/2014 for FIFA World Cup Japan vs. Côte d'Ivoire!
