Incremental Cycle Detection, Topological Ordering, and Strong Component Maintenance
Bernhard Haeupler, Telikepalli Kavitha, Rogers Mathew +2
We present two on-line algorithms for maintaining a topological order of a directed -vertex acyclic graph as arcs are added, and detecting a cycle when one is created. Our first…
From Linked Data to Relevant Data -- Time is the Essence

Sitaram Asur, Bernardo A. Huberman, Gabor Szabo +1
Social media generates a prodigious wealth of real-time content at an incessant rate. From all the content that people create and share, only a few topics manage to attract enough…
Strong Optical Confinement between Non-periodic Flat Dielectric Gratings
Jingjing Li, David Fattal, Marco Fiorentino +1
We present a novel design of optical micro-cavity where the optical energy resides primarily in free space, therefore is readily accessible to foreign objects such as atoms, molecu…
