SUMMARY:Film Screening:T.REX
DESCRIPTION:With stunning CGI visuals and the latest research from leading paleontologists\, the film offers audiences a fresh perspective on the GOAT (Greatest Of All Tyrants): Tyrannosaurus rex. Anchored by the true story of the young fossil hunters who made the discovery of a lifetime when they spotted a large fossilized leg bone on a walk on public lands in North Dakota\, T. REX intercuts the remarkable fossil dig\, with cutting edge computer graphics that bring the iconic T. rex to life—from hatchling to hulking adult. Narrated by Jurassic Park actor Sam Neill\, T. REX explores the newest science that has helped reinvent our understanding of the iconic predator.

SUMMARY:Workshop / Seminar:A reflection principle for nonintersecting paths and lozenge tilings with free boundaries (Combinatorics seminar)
DESCRIPTION:Okada and Stembridge's Pfaffian formula for the enumeration of families of nonintersecting paths with fixed starting points and unfixed ending points has been widely used to resolve many challenging problems in enumerative combinatorics. In this talk\, we present a new formula that complements Okada and Stembridge's Pfaffian formula. The combinatorial interpretation of the new formula gives a reflection principle for nonintersecting paths. It implies that the enumeration of families of nonintersecting paths with unfixed ending points can be resolved by enumerating families of nonintersecting paths with fixed ending points instead. Using this formula\, we also show that the enumeration of lozenge tilings of a large family of regions with free boundaries can be deduced from those without free boundaries and present several applications of this result.
