    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...

    Reliable Communication Infrastructure for Adaptive Data Replication

    In this paper, the authors propose a data replication algorithm adaptive to unreliable environments. The data replication algorithm, named Adaptive Data Replication (ADR), has already an adaptiveness mechanism encapsulated in its dynamic replica placement strategy. Their extension of ADR to unreliable environments provides a data replication solution that is adaptive...

    Resource-Aware Multimedia Content Delivery: A Gambling Approach

    In this paper, the authors propose a resource-aware solution to achieving reliable and scalable stream diffusion in a probabilistic model, i.e., where communication links and processes are subject to message losses and crashes, respectively. Their solution is resource-aware in the sense that it limits the memory consumption, by strictly scoping...

    The Dynamics Of Sovereign Credit Risk

    This paper provides a model for sovereign default risk valuation in which a sovereign country endogenously determines the timing of default on its external debt. The theoretical relationships between credit spreads and the macroeconomic factors considered in the model are consistent with the empirical literature. The model explains the variation...

    QuoCast: A Resource-Aware Algorithm for Reliable Peer-to-Peer Multicast

    This paper presents QuoCast, a resource-aware protocol for reliable stream diffusion in unreliable environments, where processes may crash and communication links may lose messages. QuoCast is resource-aware in the sense that it takes into account memory, CPU, and bandwidth constraints. Memory constraints are captured by the limited knowledge each process...

    RASM: A Reliable Algorithm for Scalable Multicast

    Recently there has been an effort to build scalable and reliable application-level multicast solutions that combine the resilience of pure gossip-based with the efficiency of tree-based schemes. However, such solutions assume that participants have unlimited resources, for instance, that they can send an unbounded number of messages to mask network...

    Some Common Issues On Business To Business Marketing Organization Confronted To Empirical Evidence

    This communication can be considered as a follow-up of two previous IMP communications. During the 2006 IMP Conference the status of the organizational aspect of the marketing function in the business markets was discussed (Pardo and Ivens, 2006). At this occasion, it was stressed that this issue was to be...
