The genus Arthrospira comprises filamentous cyanobacteria in which the trichomes form an open helix and contain gas vacuoles. The gas vesicle gene cluster of five Arthrospira strains was amplified by PCR and sequenced. The genes are organized in one operon, in the order gvpA1–gvpC1–gvpA2–gvpC2–gvpA3–gvpC3–gvpN. In Arthrospira sp. strain PCC 8005, the genes gvpJ, gvpK, gvpV and gvpW were also identified. Each of the three copies of gvpA encodes a protein of 71 amino acids. In the case of gvpC, there are two different length variants. Each of the two shorter genes, gvpC1 and gvpC2, encodes a putative protein of 151 amino acids, while the longer one, gvpC3, codes for a putative protein of 284 residues. The amino acid sequences of GvpC1 and GvpC2 are identical to the N-terminal part of GvpC3. In spite of the presence of stop codons downstream of gvpC1 and gvpC2, the deduced amino acid sequences in these regions are highly similar to the C-terminal part of GvpC3 (residues 160 to 229). The GvpC1, GvpC2 and GvpC3 proteins contain contiguous repeats of 33 amino acids as previously reported for other cyanobacteria. The sequences of the gvpA1, gvpC1, gvpA2 and gvpC2 genes were not found in the genome data of Arthrospira sp. PCC 8005, A. maxima CS-328, and A. platensis NIES-39 as a result of incomplete assembly. The genes gvpN and gvpJ located downstream of gvpC3, encode putative proteins of 394 and 127 amino acids, respectively. The deduced amino acid sequences of gvpK, gvpV and gvpW contain 151, 112 and 227 residues, respectively. The analysis of gvp sequences of five strains of Arthrospira revealed the presence of polymorphic positions, which distinguished the strains in agreement with their previous assignments to ITS clusters I and II. This is the first report of gvp genes in members of the genus Arthrospira. [less ▲]

We use the tools of hybrid intranuclear-cascade/nuclear-deexcitation models to evaluate the sensitivity of several physical observables to the inclusion of a multifragmentation stage in the deexcitation chain and assess the need for a multifragmentation model in the quantitative description of p + 56Fe and p + 136Xe reactions at 1-GeV incident energy. We seek clear signatures of multifragmentation by comparing different state-of-the-art deexcitation models coupled with intranuclear-cascade models and by focusing on discriminating observables such as correlations and fragment longitudinal-velocity distributions. None of the considered observables can be unambiguously interpreted as a multifragmentation footprint. The experimental data are best described as originating from sequential binary decays. However, no deexcitation model can reproduce the experimental longitudinal-velocity distributions from 1-GeV p + 136Xe. © 2011 American Physical Society. [less ▲]

Enième avatar de la bataille juridique opposant les opérateurs alternatifs de communications électroniques à l’ancien monopole public Belgacom1, la décision commentée constitue une première pour Conseil de la concurrence (« le Conseil ») à plus d’un titre : première condamnation de l’opérateur historique, première caractérisation d’un ciseau tarifaire abusif, première décision infligeant une amende aussi élevée en Belgique. Après des années de carence dans l’application des règles de concurrence au secteur des communications électroniques le Conseil parait vouloir renverser la vapeur. Sonne peut-être – comme nous l’avons écrit précédemment – la « fin de la récréation pour l’opérateur historique ». Il faut sans doute s’en féliciter, la Belgique figurant depuis longtemps parmi les mauvais élèves de l’ouverture à la concurrence des industries de réseaux. [less ▲]

The W-Arly-Pendjari (WAP) ecosystem, shared among Benin, Burkina Faso and Niger, represents the last lion stronghold of West Africa. To assess the impact of trophy hunting on lion populations in hunting areas of the WAP, we analyzed trends in harvest rates from 1999 to 2014. We also investigated whether the hunting areas with higher initial hunting intensity experienced steeper declines in lion harvest between 1999 and 2014, and whether lion densities in hunting areas were lower than in national parks. Lion harvest rate remained overall constant in the WAP. At initial hunting intensities below 1.5 lions/1000km2, most hunting areas experienced an increase in lion harvest rate, although that increase was of lower magnitude for hunting areas with higher initial hunting intensity. The proportion of hunting areas that experienced a decline in lion harvest rate increased at initial hunting intensities above 1.5 lions/1000km2. In 2014, the lion population of the WAP was estimated with a spoor count at 418 (230–648) adults and sub-adult individuals, comparable to the 311 (123–498) individuals estimated in the previous 2012 spoor survey. We found no significant lion spoor density differences between national parks and hunting areas. Hunting areas with higher mean harvest rates did not have lower lion densities. The ratio of large adult males, females and sub-adults was similar between the national parks and the hunting areas. These results suggested that the lion population was not significantly affected by hunting in the WAP. We concluded that a quota of 1 lion/1000km2 would be sustainable for the WAP. Based on our results, an import embargo on lion trophies from the WAP would not be justified. It could ruin the incentive of local actors to conserve lions in hunting areas, and lead to a drastic reduction of lion range in West Africa. [less ▲]

It is generally assumed that Janet Frame suspended the publication of some of her work in her lifetime because it was felt to be deeply personal, or potentially embarrassing for people who might recognize themselves in the portraits provided. These rationalizations fail to persuade, first because all of Frame’s published oeuvre anyway consists of a fictionalization of private existential matter, and the posthumous corpus hardly differs in this respect; and also because both Towards Another Sum- mer (2007) and In the Memorial Room (2013) feature a Kafkaesque concern with metamorphosis which serves to enhance the unrealistic tenor of the narratives, so that the novels again seem on a par with previously published self-conscious material. What is more distinctive about the new/old novels is less their allegedly embarrassing nature than their unusual degree of frontal engagement with the experience of embarrassment itself – their pondering of the pros and cons of shyness. This theme is addressed in aesthetic terms mostly. Frame’s artistic characters blush and squirm and writhe in ways which confirm the role played by embarrassment as an inadvertent recognition of, and an unwilling subscription to, an oppressive societal norm. Yet it can be shown that Frame, true to her customary dialectical mode of conceptualization, simultaneously uses embarrassment as a decentring strategy allowing the novels to work towards an exposure of so-called social normality. This exposure is achieved through a systematic policy of borrowing from, and testily reproducing, those very limited and limiting expressive codes which were found mortifying in the first place.

Embedded interface methods bring a significant simplification of the modelling process before analysis. Complex geometries and moving boundaries may be described with great flexibility, reducing the meshing step to that of a simple bounding box. Following this idea – to dissociate the field approximation from the geometric description – manifolds of different dimensions may be embedded in the same bulk mesh. However, special attention should be given to the difference of dimensions between that of problem domain and that of bulk mesh (the codimension). Whereas the direct use of the shape functions of the bulk mesh is possible for a problem domain of codimension zero, this approach is no longer possible in other configurations, for instance a beam in a 3D mesh. Unlike approaches introducing independent overlapping meshes for each subdomain, function spaces may be built from the traces of higher dimensional spaces built upon the bulk mesh. For closed curves in 2D and closed surfaces in 3D, the resulting discrete method based on P1 FE have already been studied in the literature. To avoid badly conditioned linear systems, specific treatments are required, e.g. preconditioning approaches or stabilization techniques. Here, we propose to deplete wisely the trace space. We investigate higher-order function spaces to solve the diffusion equation in embedded solids of any codimension. A new space-reducer algorithm is introduced to design the dedicated spaces that avoids ill-conditionning while treating boundary conditions. We present the results of several numerical experiments with convergence analyses. To conclude, applications of this technique to embedded beams or shells is discussed. [less ▲]

This paper focuses on the design of a dedicated P1 function space to model elliptic boundary value problem on a manifold embedded in a space of higher dimension. Using the traces of the linear P1 shape functions, it introduces an algorithm to reduce the function space into an equivalent space having the same properties than a P1 Lagrange approximation. Convergence studies involving problems of codimension one or two embedded in 2D or 3D show good accuracy with regard to classical finite element and analytical solutions. The effects of the relative position of the domain with respect to the mesh are studied in a sensitivity analysis; it illustrates how the proposed solution allows to keep the condition number bounded. A comparative study is performed with the method introduced by Olshanskii et al. 2009 on a closed surface to validate our approach. The robustness of the proposed approach is investigated with regard to their method and that of Burman et al. 2016. This paper is the first in a series of two, on the topic of embedded solids of any dimension within the context of the extended finite element method. It investigates problems involving borderless domains or domains with boundary subject to Dirichlet constraint defined only on the boundaries of the bulk mesh, while the forthcoming paper overcomes this limitation by introducing a new stable Lagrange multiplier space for Dirichlet boundary condition (and more generally stiff condition), that is valid for every combination of the background mesh and manifold dimensions. The combination of both algorithms allows to handle any embedding i.e. 1D, 2D and 3D problems embedded in 2D or 3D background meshes. [less ▲]
