After the first spike, the graph decays exponentially with apparently sinusoidal pattern to zero, indicating the possibility of two or more parameters in the denominator for the model.
The intensity of the R xx spike will depend on the relative value of the frequency term, ( w c 2 - ( w 2 ) 2 ), and the damping parameter γ in the denominator of the latter R xx expression.
Both of them lack the PLB inhibition of SERCA, i.e. we set value of parameter CaMK_reg to 1 in the denominator of equation (3).
This indicates the possibility of two or more parameters in the denominator transfer function model.
For the variable X 3t, a discrepancy of two lags and two parameters in the denominator is specified.
The situation is more difficult for reaction propensities involving for example rational terms with parameters in the denominator.
Here and are positive integers or zero (interpreting an empty product as ), and we assume (for simplicity) that the variable the numerator parameters and the denominator parameters take on complex values, provided that no zeros appear in the denominator of (1.1), that is, (1.3).
Here, p and q are positive integers or zero (interpreting an empty product as unity), and we assume for simplicity that the variable z, the numerator parameters α 1, …, α p and the denominator parameters β 1, …, β q take on complex values, provided that no zeros appear in the denominator of (1), that is, β j ∈ C ∖ Z 0 − ; j = 1, …, q. (3).
In what follows, the dimensionless Coulomb repulsive parameter μ* is therefore believed to severely reduce and, attributed to the scaling factor, ln εF/ω b appeared in the denominator of the expression of μ*.
It was found that self-substrate and cross-substrate inhibition terms which introduce nonlinearities in the denominator of the specific growth-rate expressions lead to regions of multistability in the operating parameter space.
