Vehicle stability control strategies can improve driving safety effectively; however, there is still a lack of unified evaluation criteria for different strategies. This paper proposes vehicle strategy method based on the region and analyzed by using direct yaw moment (DYC) four-wheel steering (4WS) as examples. Firstly, five-degree-of-freedom (5DOF) system models including DYC 4WS are establis...

Each subunit in a homopentameric Cys-loop receptor contains a specialized coupling region positioned between the agonist binding domain and the ion conductive channel. To determine the contribution of each coupling region to the stability of the open channel, we constructed a receptor subunit (α7-5-HT(3A)) with both a disabled coupling region and a reporter mutation that alters unitary conducta...

A system containing a pair of non-BPS D-strings of type IIA string theory on an orbifold, representing a single D2-brane wrapped on a nonsupersymmetric 2-cycle of a Calabi-Yau 3-fold with (h(1,1), h(1,2)) = (11,11), is analyzed. In certain region of the moduli space the configuration is stable. We show that beyond the region of stability the system can decay into a pair of non-BPS D3-branes. At...

A topological and dynamical characterization of the stability boundaries for a fairly large class of nonlinear autonomous dynamic systems is presented. The stability boundary of a stable equilibrium point is shown to consist of the stable manifolds of all the equilibrium points (and/or closed orbits) on the stability boundary. Several necessary and sufficient conditions are derived to determine...

We investigate the linear stability of a neural network with distributed delay, where the neurons are identical. We examine the stability of a symmetrical equilibrium point via the analysis of the characteristic equation both when the connection matrix is symmetric and when it is not. We determine a mean delay and distribution independent stability region. We then illustrate a way of improving ...
