Introduction Proteins that can regulate seemingly disparate mechanisms do so by engaging in multiple distinct protein interaction networks. Such multifunctional activities are characteristic of a protein in mammalian cells known as 'Alix' or 'AIP1'. Both names derive from its original discovery as an interaction partner of ALG-2, a Ca 2+-binding protein implicated in apoptotic signaling (Missot...

Believable agents designed for long-term interaction with human users need to adapt to them in a way which appears emotionally plausible while maintaining a consistent personality. For short-term interactions in restricted environments, scripting and state machine techniques can create agents with emotion and personality, but these methods are labor intensive, hard to extend, and brittle in new...

We discuss oxygen and cation diffusion processes in oxygen ion conductors. While the high oxygen diffusivity determines the proper oxygen ion conductivity, slow cation diffusion processes are important for sintering and degradation processes. In the first part of the paper we discuss an analytical model for the ionic conductivity of a strongly acceptor doped, fluorite-type oxygen ion conductor,...
