Representing OT hierarchies in terms of weighted sums of violations requires in the general case exponential growth of weights; and any such weight system will only work for finite fragments of grammars in which the quantity of violations incurred by optima does not grow without bound (typically, those fragments in which input size is bounded). This conclusion is based on a worst-case analysis,...

Synthesis and patterning of nanostructures of (almost) anything on anything

A necessary and very challenging condition for progress in nanoscience is being able to synthesize the requisite material. While there has been substantial success for some materials, one would like to develop protocols to fabricate structures of a wide variety of materials on an equally wide range of supports, preferably with size selection and the ability to pattern on large areas at low cost...
