We report the observation of beatings of the coincidence event rate in a Hong-Ou-Mandel interference (HOMI) between signal and idler photons from a parametric downconversion (PDC) process inside a multimode KTP waveguide. As an explanation we introduce biphotonic states entangled in their broadband frequency modes generated by waveguide mode triples and propose a suitable entanglement detection...

After a wild chimpanzee encounters a model of a dangerous snake, whether or not he gives an alarm call depends on his perception of another individual's knowledge.

Today scientists are producing large volumes of data that they wish to explore and visualize. In this paper we describe a system that combines range-based queries with fast lookup to allow a scientist to quickly and efficiently ask “what if?” questions. Unique to our system is the ability to perform “cumulative queries” that work on both an intraand inter-time step basis. The results of such qu...

Facebook has established itself as one of the major players in social networking, claiming that it helps members connect and share with the people in their lives. But what if the people you want to connect and share with are your artistic collaborators? Can Facebook be used creatively, as a collaborative artistic environment? This paper explores the creative use of Facebook as a tool for creati...

We derive the first three terms of the ε− expansion of the scalar one-loop Bhabha box function from a representation in terms of three generalized hypergeometric functions, which is valid in arbitrary dimensions.

This electron/positron identification variable summary will check our understanding of these particles’ behavior in the isolated Radiative Bhabha environment versus the highdensity hadronic environment of the CLEO detector.
