A general variational principle for fluid-structure interactions is obtained from a purely Lagrangian point of view, thus avoiding any difficulty at the fluid-structure interaction. This rather general variational principle is shown to degenerate, when suitable restrictions are made, in two known formulations, whose range of applicability is defined with the aid of three nondimensional numbers.

Based on the tensor method, a $q$-analogue of the spin-orbit coupling is introduced in a $q$-deformed Schr\" odinger equation, previously derived for a central potential. Analytic expressions for the matrix elements of the representations $j = \ell \pm 1/2$ are derived. The spectra of the harmonic oscillator and the Coulomb potential are calculated numerically as a function of the deformation parameter, without and with the spin-orbit coupling. The harmonic oscillator spectrum presents strong analogies with the bound spectrum of an Woods-Saxon potential customarily used in nuclear physics. The Coulomb spectrum simulates relativistic effects. The addition of the spin-orbit coupling reinforces this picture. [less ▲]

Recently it has been argued that a three-body colour confinement interaction can affect the stability condition of a three-quark system and the spectrum of a tetraquark described by any constituent quark model. Here we discuss the role of a three-body colour confinement interaction in a simple quark model and present some of its implications for the spectra of baryons, tetraquarks and six-quark systems.

Abstract—In power system dynamic models the complex network equations and the various phasors are projected onto reference axes. After a short critical review of commonly chosen reference axes, this letter proposes to use the center-of-inertia at the previous integration time step. This approach is shown to combine the advantages of the center-of-inertia with a sparser Jacobian structure and an easier handling of network splits. [less ▲]

This paper focuses on BGP communities, a particular BGP attribute that has not yet been extensively studied by the research community. It allows an operator to group destinations in a single entity to which the same routing decisions might be applied. In this paper, we show that the usage of this attribute has increased and that it also contributes to routing table growth. In addition, we propose a taxonomy of BGP community attributes to allow operators to better document their communities. We further manually collect information on BGP communities and tag it according to our taxonomy. We show that a large propor- tion of the BGP communities are used for traffic engineering purposes.

A new hydraulic boundary condition modelling the hydraulic transfers between porous medium and ambient atmosphere occurring during gallery excavations is described. It combines two modes of water exchanges in partial saturation: seepage and evaporation flows. Numerical simulations of a gallery excavation in dilatant geomaterial are carried out in isothermal conditions. The results show the influence of hydric boundary condition on the convergence of the gallery and the importance of the determination of vapour transfer coeffi-cient between atmosphere and porous medium.

Numerical simulations of a CCD flat-fielding calibration procedure on stellar fields have been performed in the monochromatic case. The relations between the photometric conditions, the observational procedure and the calibration accuracy are explored. This analysis shows how and why one must establish high-quality standard sequences in clusters or moderately crowded fields. The advantages of a long-term management of the reduction procedures is stressed. [less ▲]

Let k >= 2 be an integer. A set X of integers is k-recognizable if the language of k-ary representations of the elements in X is accepted by a finite automaton. The celebrated theorem of Cobham from 1969 states that if a set of integers is both k-recognizable and ℓ-recognizable, then it is a finite union of arithmetic progressions. We present several extensions of this result to nonstandard numeration systems, we describe the relationships with substitutive and automatic words and list Cobham-type results in various contexts.

Osteoporosis is a problem that is relevant to public health from the clinical, economic and social viewpoints. Except in a handful of industrialized countries, there is a considerable void in our knowledge of the magnitude of the problem. By exploring both the epidemiological and the economic impact of osteoporosis and the fractures associated with it in a particular country, studies of the 'burden of illness' (BOI) can fill that void. BOI analysis raises many questions at both the conceptual and the practical level. The purpose of this paper is to review the methodology underlying analyses of this type, to discuss its limitations and to provide a general format to improve their implementation in the field of osteoporosis. Investigators involved in BOI analysis should be very clear and explicit regarding the methods they adopt, so that studies in different countries can be interpreted and compared appropriately by interested parties.
