    Spread Spectrum Magnetic Resonance Imaging

    The authors propose a novel compressed sensing technique to accelerate the Magnetic Resonance Imaging (MRI) acquisition process. The method, coined spread spectrum MRI or simply s2MRI, consists of pre-modulating the signal of interest by a linear chirp before random k-space under-sampling, and then reconstructing the signal with non-linear algorithms that...

    ScaleStream - An Adaptive Replication Algorithm for Scalable Multimedia Streaming

    In this paper, the authors propose ScaleStream, a new algorithm to support scalable multimedia streaming in peer-to-peer networks, under strict resources constraints. With the growth of multimedia consumption over the Internet, achieving scalability in a resource-constrained environment is indeed becoming a critical requirement. Intuitively, their approach consists in dynamically replicating...

    The Demand For Liquid Assets, Corporate Saving, And Global Imbalances

    In the recent decade, capital outflows from emerging economies, in the form of a demand for liquid assets, have played a key role in the context of global imbalances. In this paper, the authors model the demand for liquid assets by firms in a dynamic open-economy macroeconomic model. They find...

    Globalization And Inflation In Europe

    What is the impact of import competition from other Low-Wage Countries (LWCs) on inflationary pressure in Western Europe? This paper seeks to understand whether laborintensive exports from emerging Europe, Asia, and other global regions have a uniform impact on producer prices in Germany, France, Italy, Sweden, and the United Kingdom....

    Financial Liberalization And Allocative Efficiency Of Capital

    Financial liberalization may have a positive effect on growth not only through the increase in the quantity of the available funds, but also through a more efficient allocation of resources across firms and sectors. Despite this intuitive appeal, there is little empirical evidence on the positive effect of financial liberalization...
