Yet, behind the scenes, a very strong assumption—or belief— resides: that there is a fixed single population parameter. In this case, the mean value of weights for teenagers in the city is a single value. Therefore, without a serious flaw in the sampling process, the parameter is constant, though unknown, across all possible samples [2]. However, what if the parameter is not fixed but rather ha...

Let us assume that some businessmen wish to have a meeting. For this to happen, they usually have to meet somewhere. If they cannot meet physically, then they can take part in a video (or audio) conference to discuss whatever needs to be discussed. But what if their meeting is meant to be private? In this case they need a cryptographic protocol that allows them to exchange their ideas remotely,...

Reputation concerns can discipline agents to take costly effort and generate good outcomes. But what if outcomes are not always observed? We consider a model of reputation with shifting observability, and ask how this affects agents’ incentives. We identify a novel and intuitive mechanism by which infrequent observation or inattention can actually strengthen reputation incentives and encourage ...

• Curvature-driven subgrain coarsening simulations mimic recrystallization in IF-steel. After the simulation, texture components appear, as also found experimentally. Subgrains near non-intergranular HAGBs do not have a size advantage. Shear/deformation band nucleation occurs by matrix subgrains invading bands. When deformation bands intersect abutting kinetic and A cellular automaton algorithm...
