Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, EarlyView.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

A Smooth Curve as a Fractal Under the Third Definition
, 2018 It is commonly believed in the literature that smooth curves, such as circles, are not fractal, and only non-smooth curves, such as coastlines, are fractal.
