biocircuits.ar_or_single

biocircuits.ar_or_single(x, y, nx, ny)

Dimensionless production rate for a gene regulated by one activator and one repressor with OR logic in the absence of leakage with single occupancy.

Parameters:

• x (float or NumPy array) – Concentration of activator.

• y (float or NumPy array) – Concentration of repressor.

• nx (float) – Hill coefficient for activator.

• ny (float) – Hill coefficient for repressor.

Returns:

output – (1 + x**nx) / (1 + x**nx + y**ny)

Return type:

NumPy array or float
