With, we denote the activity of a protein j under the experimental condition i, where and.
Let u be the node to be updated and let A t (i) denote the activity of node i as computed in the t-th iteration and let w i, j) be the weight of edge (i, j).
As shown in previous work, the striatal circuit appears almost silent in control conditions, with very little activity: each point represents the discharge of a neuron and each line denotes the activity of a neuron along time) [ 3, 8, 10, 11].
y (t ) = F liquid (x gas (t ) × ρ liquid → gas ), where y denotes the activity of the OSN, x gas the concentration in gaseous phase, and F liquid the predicted neural activity from the IFF+IFB (ODE) model introduced in Figure 4B.
where H s and H n denote the activity matrices of the source and noise dictionaries, respectively.
Each node is associated with a discrete logical state variable, which denotes the activity level of the corresponding regulatory component.
where γ denotes the activity coefficient and C the concentration of the analyte in the polymer (subscript P).
Let (C_{activity}) denote the activity type.
The quantities θ v θ s θ f and θ l denote the activities (the effective supersaturations) of group III element in the vapor (v), surface adatom (s), sidewall adatom (f) and liquid (l) phases, with the usual definition of θ i = exp(μ i /k B T), where μ i is the chemical potential in phase i (measured, e.g., with respect to the solid phase) and k B is the Boltzmann constant [6].
Relevant parameters are set as follows: A denotes the random activity of BS within a Poisson-Voronoi cell and takes values in [0,1], A i represents user activity within the cell that a BS covers, and A i and A satisfy A i ∼A.
