We demonstrate that a simple solar dynamo model, in the form of a Parker migratory dynamo with random fluctuations of the dynamo governing parameters and algebraic saturation of dynamo action, can at least qualitatively reproduce all the basic features of solar Grand Minima as they are known from direct and indirect data. In particular, the model successfully reproduces such features as an abru...

In this position paper, we argue that usable privacy and security is a grand challenge that needs more attention from the HCI community. We also discuss benefits to and new challenges for HCI, and use our research experiences to provide a critique of HCI. Usable Privacy and Security: A Grand Challenge for HCI Jason I.

We study interacting Bose gases in thermal equilibrium on a lattice. establish convergence of the grand-canonical Gibbs states such to their mean-field (classical field) and large-mass particle) limits. The former is classical field theory for complex scalar with quartic self-interaction. latter point particles two-body interactions. Our analysis based representations terms ensembles random loo...
