Nature Communications, 2018 The ability of proteins to sense membrane curvature is essential to cellular function. All known sensing mechanisms rely on protein domains with specific structural features such as wedge-like amphipathic helices and crescent-shaped BAR domains. Yet many

Vision Research, 1989 Hypercomplex or endstopped visual cortical neurons are usually supposed to be concerned with length or end point analysis. However, recent evidence demonstrates that endstopped neurons are curvature-selective, a connection that we explore here in some detail.

Period problems for mean curvature one surfaces in $H^3$ (with application to surfaces of low total curvature) [PDF]
Adv. Studies in Pure Math. 51 (2008), 335-387, Surveys on Geometry
and Integrable Systems, 2008 We review recent results on classifying complete constant mean curvature 1 (CMC 1) surfaces in hyperbolic 3-space with low total curvature. There are two natural notions of "total curvature" -- one is the total absolute curvature, which is the integral over the surface of the absolute value of the Gaussian curvature, and the other is the dual total ...

Curvature and transport inequalities for Markov chains in discrete spaces [PDF]
arXiv, 2015 We study various transport-information inequalities under three different notions of Ricci curvature in the discrete setting: the curvature-dimension condition of Bakry and \'Emery, the exponential curvature-dimension condition of Bauer \textit{et al.} and the coarse Ricci curvature of Ollivier.

Critical points and curvature in circular clamped plates
Electronic Journal of Differential Equations, 2014 In this article we investigate some qualitative properties of the solutions of the classical linear model for clamped plates on circular domains, under constant sign external loads.

Remark about scalar curvature and Riemannian submersions [PDF]
arXiv, 2005 We consider modified scalar curvature functions for Riemannian manifolds equipped with smooth measures. Given a Riemannian submersion whose fiber transport is measure-preserving up to constants, we show that the modified scalar curvature of the base is bounded below in terms of the scalar curvatures of the total space and fibers. We give an application
