WebFig. 4.1. The modified potential G for α > α∗ (solid) and α = α∗ (dotted). At α = α∗ the potential G has a double zero at u = φ∗m(b). Increasing the value of α above α∗ lowers G about its pivot point at u = b, where it maintains a double zero. The double zero at u = φ∗m breaks into two zeros of G, the smaller of which, denoted φm , is also the maximum of … WebDec 31, 2016 · We investigate the stability and slow geometric evolution of multicomponent bilayer interfaces within the context of an \(H^{-1}\) gradient flow of the mFCH, addressing the impact of aspect ratio of the amphiphile (lipid or copolymer unit) on the intrinsic curvature and the codimensional bifurcation. In particular we derive a Canham–Helfrich ...

WebDec 1, 2024 · Continuum or hybrid modeling of bilayer membrane morphological dynamics induced by embedded proteins necessitates the identification of protein-membrane interfaces and coupling of deformations of two surfaces. In this article we developed (i) a minimal total geodesic curvature model to describe thes … WebSep 22, 2024 · Many of the curvature generating aspects in membranes can be attributed to interactions between proteins and membranes. These interactions include protein diffusion and formation of aggregates due to protein-protein interactions in the plane of the membrane. Recently, we developed a model that couples the in-plane flow of lipids and … brown bear 747
