Holditch’s Envelope

Communications in Optimization Theory, 2022
Summary: An implicit assumption in the original version of Holditch's theorem is \(C^1\)-regularity and strict convexity of the envelope generated by a chord traveling around a convex curve \(\mathbb{C}\). We establish that this holds when \(\mathbb{C}\) is \(C^2\)-regular with positive curvature and the chordlength is sufficiently small.

Enveloped Viruses

2003
A distinguishing physical feature of many viruses is the presence of a host-derived lipid bilayer. This feature of the virus particle has important consequences for the assembly and release as well as the entry pathway for a particular virus. Significant advances have been made in our understanding of enveloped viruses.
