Query: Finite Temperature Phase Behavior of Viral Capsids as Oriented Particle
  Shells   A general phase-plot is proposed for discrete particle shells that allows for
thermal fluctuations of the shell geometry and of the inter-particle
connectivities. The phase plot contains a first-order melting transition, a
buckling transition and a collapse transition and is used to interpret the
thermodynamics of microbiological shells.
