Flutter-type dynamic instability induced by friction is a highly nonlinear phenomenon and computationally expensive to model through transient analysis.An efficient way to make inference of such instabilities in a dynamical system is through analyzing the first-order effect of a perturbation at one of its equilibrium with eigenvalue analysis.The co
ABSTRACT Enterovirus genome replication occurs at virus-induced structures derived from cellular membranes and lipids.However, the origin of these replication organelles (ROs) remains uncertain.Ultrastructural evidence of the membrane donor is lacking, suggesting that the sites of its transition into ROs are rare or fleeting.To overcome this challe
