    An Overview of LISA Data Analysis Algorithms

    Full text link
    The development of search algorithms for gravitational wave sources in the LISA data stream is currently a very active area of research. It has become clear that not only does difficulty lie in searching for the individual sources, but in the case of galactic binaries, evaluating the fidelity of resolved sources also turns out to be a major challenge in itself. In this article we review the current status of developed algorithms for galactic binary, non-spinning supermassive black hole binary and extreme mass ratio inspiral sources. While covering the vast majority of algorithms, we will highlight those that represent the state of the art in terms of speed and accuracy.Comment: 21 pages.

    Small-Dollar Lending: Is There A Responsible Path Forward?

    This report examines the problem of access to credit for low- and moderate- income households. It notes that this problem has two dimensions. On the one hand, there are millions of consumers without access to mainstream sources of consumer credit. On the other hand, many of these same consumers do obtain high-cost credit that ends up harming rather than helping them

    Introduction to dynamical large deviations of Markov processes

    Full text link
    These notes give a summary of techniques used in large deviation theory to study the fluctuations of time-additive quantities, called dynamical observables, defined in the context of Langevin-type equations, which model equilibrium and nonequilibrium processes driven by external forces and noise sources. These fluctuations are described by large deviation functions, obtained by solving a dominant eigenvalue problem similar to the problem of finding the ground state energy of quantum systems. This analogy is used to explain the differences that exist between the fluctuations of equilibrium and nonequilibrium processes. An example involving the Ornstein-Uhlenbeck process is worked out in detail to illustrate these methods. Exercises, at the end of the notes, also complement the theory.Comment: 19 pages.

    Interpodes: Poland, Tom Keneally and Australian Literary History

    Get PDF
    Poland features in a number of Keneally’s books and is one of the leading sources of translation for his work. The article explores possible causes and effects around this fact, and surveys some reader responses from Poland. It notes the connections that Keneally’s Catholic background and activist sympathies allow to modern Polish history and assesses the central place of his Booker-winning Schindler’s Ark filmed as Schindler’s List

    This paper presents individual country notes for the paper "Trends in Rentier Shares in OECD Countries, 1966-2000 (Power, Epstein and Abrena, 2003). Meant for the specialist, these notes explain data sources and methods for each country in our sample.

    Organic Centre Wales Technical Note 5: Biology and management of wireworms

    Get PDF
    Wireworms are the larvae of a group of beetles commonly known as click beetles. After falling on their backs they right themselves by flicking themselves into the air and produce a “clicking” sound. There are about 60 species of click beetle in the UK, but the majority of attacks are caused by three Agriotes species (lineatus, obscurus and spuator). This technical notes lists natural enemies of wireworms, nature of damage, life history and control measures, and a list of sources of further information
