    Building on the assumptions that decadence is a complex and transnational phenomenon, this volume proposes fresh understandings of the theory and practice of translation. Icelandic poetry and a Japanese novel rub shoulders with Latvian translations of Oscar Wilde’s The Picture of Dorian Gray and early twentieth-century translations of Baudelaire by Cyril Scott, who also set some of Ernest Dowson’s verse into song. Strindberg’s ‘Sensations dĂ©traquĂ©es’, one of the few texts he wrote in French, and G. B. Shaw’s recent translation of Widower’s Houses into Italian reveal how decadence was received in different countries and different periods, from the late nineteenth century to contemporary times, as well as demonstrate the flexibility of translation practice, which no longer signifies mere linguistic equivalence. On the contrary, translation appears as a mode of reception, attentive to cultural geographies and historical transformations, as a means of practising intermediality, or as a creative activity, sometimes dangerously close to appropriation and rewriting, thereby raising ethical questions. With its focus on hitherto neglected areas and artists and its insistence on the centrality of translation, this volume is a timely addition to the now well-established field of decadence studies

    Local regularity for parabolic nonlocal operators

    Full text link
    Weak solutions to parabolic integro-differential operators of order α∈(α0,2)\alpha \in (\alpha_0, 2) are studied. Local a priori estimates of H\"older norms and a weak Harnack inequality are proved. These results are robust with respect to α↗2\alpha \nearrow 2. In this sense, the presentation is an extension of Moser's result in 1971.Comment: 31 pages, 3 figure

    Spatial Mixing and Non-local Markov chains

    Full text link
    We consider spin systems with nearest-neighbor interactions on an nn-vertex dd-dimensional cube of the integer lattice graph Zd\mathbb{Z}^d. We study the effects that exponential decay with distance of spin correlations, specifically the strong spatial mixing condition (SSM), has on the rate of convergence to equilibrium distribution of non-local Markov chains. We prove that SSM implies O(log⁥n)O(\log n) mixing of a block dynamics whose steps can be implemented efficiently. We then develop a methodology, consisting of several new comparison inequalities concerning various block dynamics, that allow us to extend this result to other non-local dynamics. As a first application of our method we prove that, if SSM holds, then the relaxation time (i.e., the inverse spectral gap) of general block dynamics is O(r)O(r), where rr is the number of blocks. A second application of our technology concerns the Swendsen-Wang dynamics for the ferromagnetic Ising and Potts models. We show that SSM implies an O(1)O(1) bound for the relaxation time. As a by-product of this implication we observe that the relaxation time of the Swendsen-Wang dynamics in square boxes of Z2\mathbb{Z}^2 is O(1)O(1) throughout the subcritical regime of the qq-state Potts model, for all q≄2q \ge 2. We also prove that for monotone spin systems SSM implies that the mixing time of systematic scan dynamics is O(log⁥n(log⁥log⁥n)2)O(\log n (\log \log n)^2). Systematic scan dynamics are widely employed in practice but have proved hard to analyze. Our proofs use a variety of techniques for the analysis of Markov chains including coupling, functional analysis and linear algebra

    Using the hydrographic and nutrient data from the R/V Jean Charcot CINECA-V cruise and Broenkow\u27s (1965) mixing model, we have calculated the biologically induced changes in the oxygen, nitrate and ammonium distribution patterns of the upwelling system off Cape Blanc, N .W. Africa...

    Synthesis by the polyol process and ionic conductivity of nanostructured La2Mo2O9 powders

    Get PDF
    International audienceLa2Mo2O9 nanostructured powders were synthesized by the polyol process. The effects of the nature of the polyol, the refluxing time, the hydrolysis ratio, the metal concentration and the addition of hydroxide ions, on the purity and morphology of the powders are determined. Two main morphologies are observed, the particles being in the shape of platelets or spheres, with respectively diethylene glycol or ethylene glycol as solvent. A specific surface area of 24 m2/g was reached by varying the metal concentration. The conductivity measurements were recorded on pellets that present in some cases a closed porosity, the relative density reaching 95% without any milling step. According to the synthesis parameters, the grain conductivity can be slightly increased, the total conductivity remaining only slightly lower than that of pellets made of powders synthesized by solid state reaction

    Uncertainty inequalities on groups and homogeneous spaces via isoperimetric inequalities

    Full text link
    We prove a family of LpL^p uncertainty inequalities on fairly general groups and homogeneous spaces, both in the smooth and in the discrete setting. The crucial point is the proof of the L1L^1 endpoint, which is derived from a general weak isoperimetric inequality.Comment: 17 page

    Quantitative Timed Analysis of Interactive Markov Chains

    Get PDF
    Abstract This paper presents new algorithms and accompanying tool support for analyzing interactive Markov chains (IMCs), a stochastic timed 1 1 2-player game in which delays are exponentially distributed. IMCs are compositional and act as semantic model for engineering for-malisms such as AADL and dynamic fault trees. We provide algorithms for determining the extremal expected time of reaching a set of states, and the long-run average of time spent in a set of states. The prototypical tool Imca supports these algorithms as well as the synthesis of Δ-optimal piecewise constant timed policies for timed reachability objectives. Two case studies show the feasibility and scalability of the algorithms.

    Power-Laws in Nonlinear Granular Chain under Gravity

    Full text link
    The signal generated by a weak impulse propagates in an oscillatory way and dispersively in a gravitationally compacted granular chain. For the power-law type contact force, we show analytically that the type of dispersion follows power-laws in depth. The power-law for grain displacement signal is given by h−1/4(1−1/p)h^{-1/4(1-1/p)} where hh and pp denote depth and the exponent of contact force, and the power-law for the grain velocity is h−1/4(1/3+1/p)h^{-1/4({1/3}+1/p)}. Other depth-dependent power-laws for oscillation frequency, wavelength, and period are given by combining above two and the phase velocity power-law h1/2(1−1/p)h^{1/2(1-1/p)}. We verify above power-laws by comparing with the data obtained by numerical simulations.Comment: 12 pages, 3 figures; Changed conten

    Abstract Argumentation / Persuasion / Dynamics

    Full text link
    The act of persuasion, a key component in rhetoric argumentation, may be viewed as a dynamics modifier. We extend Dung's frameworks with acts of persuasion among agents, and consider interactions among attack, persuasion and defence that have been largely unheeded so far. We characterise basic notions of admissibilities in this framework, and show a way of enriching them through, effectively, CTL (computation tree logic) encoding, which also permits importation of the theoretical results known to the logic into our argumentation frameworks. Our aim is to complement the growing interest in coordination of static and dynamic argumentation.Comment: Arisaka R., Satoh K. (2018) Abstract Argumentation / Persuasion / Dynamics.

    Architecture for Integrated Mems Resonators Quality Factor Measurement

    Get PDF
    In this paper, an architecture designed for electrical measurement of the quality factor of MEMS resonators is proposed. An estimation of the measurement performance is made using PSPICE simulations taking into account the component's non-idealities. An error on the measured Q value of only several percent is achievable, at a small integration cost, for sufficiently high quality factor values (Q > 100).Comment: Submitted on behalf of EDA Publishing Association (http://irevues.inist.fr/EDA-Publishing
