Table 1. Summary of variables.

Input variables Function (variable name used in program)
rows # rows (rows)
columns # columns (columns)
time steps # time iterations used for the simulation (timesteps)
starting pressure initial pressure used to calculate the initial activities (initialpressure)
minimum pressure minimum pressure within the uterus (minpressure)
maximum burst duration maximum # time iterations for each burst (timeburst)
refractory duration maximum # time iterations of the refractory period (timerefractory)
Action potential multiplier factor that increases act(i,j) during an action potential (burstmultiplier)
refractory multiplier multiplier used when tissue is in refractory period (refractorymultiplier)
weibullvar1 shape of the Weibull distribution for anatomy sensitivity (anatomysens)
weibullvar2 scope of the Weibull distribution for anatomy sensitivity
weibullvar3 start of the Weibull distribution for anatomy sensitivity
weibullvar4 shape of the Weibull distribution for action potential threshold (burstthreshold)
weibullvar5 scope of the Weibull distribution for action potential threshold
weibullvar6 start of the Weibull distribution for action potential threshold
Calculation/output variables
pressure intrauterine pressure at each time step
act(i,j) contractile activity of the i,j region at a given time
activity(i,j,t) the tensor of act(i,j), remembers all act(i,j) at all times
anatomysens(i,j) sensitivity of the i,j region because of physical shape
anatomysenstensor(i,j,t) the tensor that holds anatomysens(i,j)
burstthreshold(i,j) action potential threshold for the i,j region
burst(i,j) applies burstmultiplier if above threshold
refractoryfactor(i,j) applies refractorymultiplier if in refractory period
refractory(i,j,t) the tensor that holds refractoryfactor(i,j)
pressurevector(t) the vector that remembers the pressure at all times
