, 2012 A Ricci surface is a Riemannian 2-manifold $(M,g)$ whose Gaussian curvature $K$ satisfies $K\Delta K+g(dK,dK)+4K^3=0$. Every minimal surface isometrically embedded in $\mathbb{R}^3$ is a Ricci surface of non-positive curvature.

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs
Advanced Healthcare Materials, Volume 15, Issue 5, 2 February 2026.Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

η-Ricci Solitons on Kenmotsu 3-Manifolds
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 In the present paper we study η-Ricci solitons on Kenmotsu 3-manifolds. Moreover, we consider η-Ricci solitons on Kenmotsu 3-manifolds with Codazzi type of Ricci tensor and cyclic parallel Ricci tensor.

Curvature estimates for the Ricci flow I [PDF]
Calculus of Variations and Partial Differential Equations, 2007 In this paper we present several curvature estimates and convergence results for solutions of the Ricci flow. The curvature estimates depend on smallness of certain local space-time integrals of the norm of the Riemann curvature tensor, while the convergence results require finiteness of space-time integrals of the norm of the Riemann curvature tensor.

Advanced Science, Volume 13, Issue 7, 3 February 2026.This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Some New results in Ricci Curvature
Irish Mathematical Society Bulletin, 1996 The main results of the author's Ph. D. thesis [University of Notre Dame (1995)] are announced: an improvement of a surgery theorem for positive Ricci curvature originally given by \textit{J.-P. Sha} and \textit{D.-G. Yang} [J. Differ. Geom. 33, No.
