Morpho butterflies are well known for their brilliant iridescent colors, which arise from periodic arrays of scales. These brilliant colors have a low angle dependence, in contrast to similar phenomena that are commonly caused by the periodic structures. We designed a structure with a low incident and viewing angle dependence inspired by Morpho butterflies. This structure was studied using the ...

In this paper, we present the XYZ Privacy mechanism. XYZ Privacy maintains constant error from the ground truth while each data owner submits multiple contradictory responses, achieves scalable non-attributable (privatized) writes, and it protects the aggregate answer against malicious data owners attempts to corrupt (e.g., pollution attacks). We show an optimization of a square root reduction ...
