The author establishes a property of supply for a competitive firm: Assuming differentiability of the production frontier, linearly independent price vectors have disjoint image sets under the supply ...

A new study has revealed how epithelial cells respond to the curvature of tissue gaps by changing the shape of an internal organelle, the endoplasmic reticulum (ER), to support different modes of ...

We study the conformal deformation equation Δu − 2kg + 2Keu = 0 on noncompact surfaces of finite topological type with K nonpositive. Sharp existence and nonexistence results are obtained. There are ...

Due to its overarching role in genome function, sequence-dependent DNA curvature continues to attract great attention. The DNA double helix is not a rigid cylinder, but presents both curvature and ...
