Teer 203
Speaker: Junier Oliva, Ph.D. candidate in the Machine Learning Department at the School of Computer Science, Carnegie Mellon University
A great deal of attention has been applied to studying new and better ways to perform learning tasks involving static finite vectors. Indeed, over the past century the fields of statistics and machine learning have amassed a vast understanding of various learning tasks like clustering,... Read More »

Physics 278
Speaker: Blake Burghgrave (Northern Illinois University)
The experimental observation of charged Higgs bosons, whose existence is predicted by several models with an extended Higgs sector, would be an unambiguous signal for physics beyond the Standard Model (SM). This presentation describes an ongoing search for charged Higgs bosons in 36 fb^-1 of... Read More »

Physics 128
Speaker: Wolfgang Losert (University of Maryland)
"Guided Cell Migration - A Dynamical Systems Perspective" - The guided migration of cells is a complex dynamical process involving carefully regulated polymerization and depolymerization of the elements of the cellular scaffolding, in particular actin. Recent work has shown that polymerizing and... Read More »

Physics 298
Speaker: James R. Williams (University of Maryland, College Park)
Josephson junctions are quantum circuit elements commonly associated with use as fundamental units in quantum computation. These junctions may also play a fundamental role in probing complex materials that have eluded characterization by conventional means. In this talk I'll be presenting some of... Read More »

Physics 128
Speaker: Elinor Medezinski (Princeton)
"Weighing Galaxy Clusters with Weak Lensing" - The most fundamental question in observational cosmology today is what is the nature of dark energy and dark matter. As the most massive gravitationally bound bodies in the Universe, clusters of galaxies serve as beacons to the growth of structure over... Read More »
