We relate the entropy of entanglement of ensembles of random vectors to their generalized fractal dimensions. Expanding the von Neumann entropy around its maximum we show that the first order only depends on the participation ratio, while higher orders involve other multifractal exponents. These results can be applied to entanglement behavior near the Anderson transition. [less ▲]

The low quality of service provided by wireless networks does not facilitate the setup of long-awaited services, such as video conversations. In a cellular network, handoffs are an important cause of packet losses and delay jitter. These problems can be mitigated if proactive measures are taken. This requires each cell to guess the next handoff of each mobile terminal, a problem known as mobility prediction. This prediction can occur thanks to some clues (such as signal strength measurements) giving information about the terminals motion. For example, a clue that locates on which road a mobile is moving is likely to be interesting for all the prediction-enabled cells along that road ---and should therefore be sent to them. This paper proposes a new method aimed at selecting the most relevant clues and finding where to propagate those clues so as to optimize mobility predictions. The pertinence of a clue is measured using information theory and by means of decision trees. This pertinence estimation is exchanged between the cells and allows to build a"relevance map" that helps determine where clues should be sent. It is adapted to the characteristics of wireless terminals such as low bandwidth and processing power. [less ▲]

We show that various aspects of k-automatic sequences — such as having an unbordered factor of length n — are both decidable and effectively enumerable. As a consequence it follows that many related sequences are either k-automatic or k-regular. These include many sequences previously studied in the literature, such as the recurrence function, the appearance function, and the repetitivity index. We also give some new characterizations of the class of k-regular sequences. Many results extend to other sequences defined in terms of Pisot numeration systems. [less ▲]

This paper is based on Derrida’s deconstruction of significance, and focuses on how media-based discourses organize the audience in a public space. In audience studies, the text/reader relationship remains a difficult point because it remains unclear how to account for the fact that the media structure perception, although they do not determine it. To solve this contradiction, we need to link together facts and possibilities (empirical and transcendental levels) in a way that keeps alive this relationship between a text and a reader. This is what Jacques Derrida’s work makes possible. We’ll mainly use his concepts of “address” and “destination”. The “address” might be considered as an attempt to translate the linguistic “enunciation” into phenomenological terms: the address modifies reference and thus inscribes the reader in a “world”. As for the “destination”, it refers to a model where communication is indeterminate (“incalculable”). This model gives readers the opportunity to create previously unseen kinds of worlds, or communities of “common sense”. In this way, this model is political. Our analysis allows us to account for both representations of the world and places given to readers in this world, so that we can describe, with this “sharing of the sensory”, mediated experience as political.

In 2004, the Butgenbach lake reservoir (Warche river) has been emptied for the first time since 1932. The sediments deposited have been studied with a double objective : on the one hand to determine the volume of sediment deposits, and on the other hand to estimate mean soil erosion rate in the catchment. Some five hundreds manual augerings were made using a thin auger (15 mm) throughout the wet and soft sediments (mud) in order to identify the lake deposits that have overlain the previous soft material (flood silts in the flood plain of the river Warche, silty soils on the slopes). Since the expected boundary between both types of materials could not be identified by the naked eye, a qualitative analysis of diatoms, magnetic susceptibility, grain-size distribution and calcination has been made for fifteen thicker cores (3.6 mm across) taken at representative sites. Mean annual area-specific sediment yield amounts to 28 – 33 t.km-².y-1 [less ▲]

The amplitude modulation of magnetic field-aligned circularly polarized electromagnetic (CPEM) waves in a magnetized pair plasma is reexamined. The nonlinear frequency shifts include the effects of the radiation pressure driven density and compressional magnetic field perturbations as well as relativistic particle mass variations. The dynamics of the modulated CPEM wave packets is governed by a nonlinear Schrodinger equation, which has attractive and repulsive interaction potentials for fast and slow CPEM waves. The modulational stability of a constant amplitude CPEM wave is studied by deriving a nonlinear dispersion from the cubic Schrodinger equation. The fast (slow) CPEM mode is modulationally unstable (stable). Possible stationary amplitude solutions of the modulated fast (slow) CPEM mode can be represented in the form of bright and dark/gray envelope electromagnetic soliton structures. Localized envelope excitations can be associated with the microstructures in pulsar magnetospheres and in laboratory pair magnetoplasmas. (C) 2005 American Institute of Physics. [less ▲]
