Abstract:
In a recent work [R. Shojaei et al., Phys. Rev. E 100, 022303 (2019)2470-004510.1103/PhysRevE.100.022303] the authors calculate numerically the critical temperature T_{c} of the balanced-imbalanced phase transition in a fully connected graph. According to their findings, T_{c} decreases with the number of nodes N. Here we calculate the same critical temperature using the heat-bath algorithm. We show that T_{c} increases with N as N^{γ}, with γ close to 0.5 or 1.0. This value depends on the initial fraction of positive bonds.

Stability of Equilibrium Configuration
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
BIBO stability of continuous and discrete -time systems
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....
Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...
Theories of Dissolution: Diffusion Layer Model
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
