Surface Energy of Curved Surface Based on Lennard-Jones Potential
Nanomaterials, 2021 Although various phenomena have confirmed that surface geometry has an impact on surface energy at micro/nano scales, determining the surface energy on micro/nano curved surfaces remains a challenge.

Liquid harvesting and transport on multiscaled curvatures
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Although various creatures possess different structural gradients to gather water from fog, such as spider silk and cactus cluster, their gradient surfaces can only drive the motion of harvested water droplets over only a limited drop-sized ...

Chern-Ricci curvatures, holomorphic sectional curvature and Hermitian metrics [PDF]
Science China Mathematics, 2019 We present some formulae related to the Chern-Ricci curvatures and scalar curvatures of special Hermitian metrics. We prove that a compact locally conformal Kähler manifold with constant nonpositive holomorphic sectional curvature is Kähler. We also give

International Journal of Modern Physics D, 2002 The issues of quintessence and cosmic acceleration can be discussed in the framework of higher order theories of gravity. We can define effective pressure and energy density directly connected to the Ricci scalar of curvature of a generic fourth order theory and then ask for the conditions to get an accelerated expansion.

Scalar curvatures in almost Hermitian geometry and some applications [PDF]
Science China Mathematics, 2019 On an almost Hermitian manifold, there are two Hermitian scalar curvatures associated with a canonical Hermitian connection. In this paper, two explicit formulas on these two scalar curvatures are obtained in terms of the Riemannian scalar curvature ...

Curvatures, graph products and Ricci flatness [PDF]
Journal of Graph Theory, 2019 In this paper, we compare Ollivier–Ricci curvature and Bakry–Émery curvature notions on combinatorial graphs and discuss connections to various types of Ricci flatness.

Sensing Membrane Curvature [PDF]
Developmental Cell, 2003 AbstractTransport vesicle formation and fusion are highly regulated processes that require the sequential assembly and disassembly of proteinacious membrane coats. Recent work suggests that one of the coat proteins senses the local changes in lipid packing that accompany membrane bending during vesiculation, and thus acts as a timer for coat ...

SSRN Electronic Journal, 2021 In a Mirrleesian environment, a monopsonist sets hourly wages and individuals choose how many hours to work. Labor market outcomes do not only depend on the level and slope of the income tax function, but also on its curvature. A more concave tax schedule raises the elasticity of labor supply, which boosts wages.
