The nonverbal transmission of information between social animals is a primary driving force behind their actions and, therefore, an important quantity to measure in animal behavior studies. Despite its key role in social behavior, the flow of information has only been inferred by correlating the actions of individuals with a simplifying assumption of linearity. In this paper, we leverage inform...

Euclidean wormholes---geometries which connect disconnected boundaries---present a challenge to standard quantum mechanical interpretation of the theory. One potential resolution is that gravitational path integral computes ensemble average many theories. The connected topologies contribute simplest possible observable: free energy, computed using replica trick. This distinct from trick used co...

In this study, we examined the fine structure of the compound eyes of a household fly and precisely replicated its entire structure using a low-temperature atomic layer deposition technique. The surface of the fly eye is found to be covered by highly packed protuberances, which potentially increases visual efficiency through increased photon capture for a given stimulus. The alumina replica was...
