    Abstract:

    The last decade has seen the growth of data sets that are not only extremely large, but also often unstructured and very dynamic, with the desire to extract not just specific facts about specific entities but also relationships between possibly arbitrary entities. Graphs have emerged as a valuable and productive paradigm for expressing such problems, and there has been an explosion in new graph algorithms, graph query languages, and graph engines that perform such computations. However, to da…

    Abstract:

    Various migration-related controversies in the United States and the 2015 migrant crisis in Europe have raised questions about destination countries’ treatment of migrants. This report, produced in collaboration with the department of Migration and Refugee Services of the United States Conference of Catholic Bishops, considers the post-arrival side of immigration enforcement in the United States, Greece, and Germany through a normative lens. It asks: What does it mean for immigration enfo…

    Description:

    A common computational problem is to compute topological information about a real surface defined by a system of polynomial equations. Our software, called polyTop, leverages numerical algebraic geometry computations from Bertini and Bertini_real with topological computations in javaPlex to compute the Euler characteristic, genus, Betti numbers, and generators of the fundamental group of a real surface. Several examples are used to demonstrate this new software.

    Description:

    Three key aspects of applying homotopy continuation to parameterized systems of polynomial equations are investigated. First, for parameterized systems which are homogenized with solutions in projective space, we investigate options for selecting the affine patch where computations are performed. Second, for parameterized systems which are overdetermined, we investigate options for randomizing the system for improving the numerically stability of the computations. Finally, since one is typica…

    Description:

    Matlab code that computes the effective point spread functions (EPSF) that results from exciting a two level fluorescence system with modulated excitation in saturation. The model is based on solving the rate equation for the two level system accounting for two photon absorption, stimulated and spontaneous emission. Each PSF is solved for every time pulse and point in 3 dimensional space in a series of loops over sinusoidally modulated excitation signals.
