Some of the most dramatic engineering feats accomplished with layered materials are enabled by properties that emerge only at the single or few-layer limit and are not found in bulk forms. I will discuss our efforts to elucidate useful emergent properties of monolayer and few-layer materials, including our predictions and several recent experimental observations of substantive electromechanical coupling in the form of piezoelectric1–3 and flexoelectric-like effects,4 unlike their bulk forms.

We describe a mathematical framework for dimensional reduction, learning and organization of databases . The database could be a matrix of a linear transformation for which the goal is to reorganize the matrix so as to achieve compression and fast algorithms. Or the database could be a collection of documents and their vocabulary, an array of sensor measurements such as EEG , or financial a time series or segments of recorded music.
