La gestion touristique des espaces littoraux de la station balnéaire de Cap-Skirring (Sénégal)

description: Les espaces littoraux représentent des milieux naturels mobiles qui sont soumis aux évolutions des phénomènes naturelles (lithosphère, hydrosphère, atmosphère) et des actions anthropiques, modifiant les équilibres anciens et augmentant les vulnérabilités sociétales. Modelés par le déferlement des vagues, adoucis ou endurcis par le climat, ils sont menacés par les forces de la nature et des êtres humains. Leur gestion durable est devenue une préoccupation majeure surtout dans les pays africains fragilisés par l’accélération des changements climatiques et sociétaux. Cette étude s’intéresse particulièrement à la problématique de la territorialisation et de la résidentialisation de la station balnéaire de Cap-Skirring, située à l’extrême Sud-ouest du Sénégal. Elle se penche sur l’occupation anarchique de ses espaces littoraux par le biais du tourisme, devenu une menace pour le littoral même s’il contribue au développement économique. L’objectif est d’analyser les enjeux politiques, socioéconomiques et environnementaux du développement touristique sur le littoral. La méthodologie utilisée est basée sur les recherches documentaires, les observations participatives et la collecte de données aussi bien quantitatives que qualitatives. Les résultats obtenus montrent que le développement du tourisme balnéaire a favorisé l’augmentation de la population locale, ce qui représente une menace pour les écosystèmes. Ils montrent aussi que le manque de gestion intégrée des zones côtières et l’absence de plan d’aménagement touristique ont engendré des pressions foncières dans la zone, pouvant causer une crise écologique.

description: A total synthesis of ß-carotene is described. First a C19-aldehyde was built up by condensation of ß-C14-aldehyde with a C5-ethinyl-oxy-ether. Then two molecules of the partially hydrogenated C19-aldehyde were condensed with acetylene-dimagnesiumbromide resulting in a C4o-acetylene-diol, which was dehydrated, giving rise to a ß-carotene-9,9'-ine or 9,9'-dehydro-ß-carotene. The last step consisted in the adding of two hydrogen atoms to the triple bond of the compound C40H54 furnishing a mixture of cis-trans-ß-carotene-isomers. From this mixture dark-red-violet crystals could be isolated which after recrystallisation melted at 178-179° and gave no depression of the melting point when mixed with natural ß-carotene, F. 179°.
On the parameters of Lewis metric for the Weyl class

description: We provide physical interpretation for the four parameters of the stationary Lewis metric restricted to the Weyl class. Matching this spacetime to a completely anisotropic, rigidly rotating, fluid cilinder, we obtain from the junction conditions that one of these parameters is proportional to the vorticity of the source. From the Newtonian approximation a second parameter is found to be proportional to the energy per unit of length. The remaining two parameters may be associated to a gravitational analog of the Aharanov-Bohm effect. We prove, using the Cartan scalars, that the Weyl class metric and static Levi-Civita metric are locally equivalent, i.e., indistinguishable in terms of its curvature.

description: We quantize a flat cosmological model in the context of $f(T)$ theory of modified gravity using the Dirac's quantization approach for Hamiltonian constraint systems. In this regard, first we obtain the Wheeler-DeWitt equation as the operator equation of the Hamiltonian constraint and solve it for some typical cosmological models of $f(T)=T-2Λ$, $f(T)= β\sqrt{-2T}$ and $f(T)= γT^2$. Then, in the context of classical-quantum correspondence, we interpret the obtained wavefunctions of the universe to describe an accelerating de Sitter universe which is found to be in good agreement with $f(T)=T-2Λ$ model. Finally, we study Bohm--de Broglie interpretation of the quantum model for $f(T)=T-2Λ$ model.

description: We discuss three measures of the degree of contextuality in contextual systems of dichotomous random variables. These measures are developed within the framework of the Contextuality-by-Default (CbD) theory, and apply to inconsistently connected systems (those with "disturbance" allowed). For one of these measures of contextuality, presented here for the first time, we construct a corresponding measure of the degree of noncontextuality in noncontextual systems. The other two CbD-based measures do not suggest ways in which degree of noncontextuality of a noncontextual system can be quantified. We find the same to be true for the contextual fraction measure developed by Abramsky, Barbosa, and Mansfield. This measure of contextuality is confined to consistently connected systems, but CbD allows one to generalize it to arbitrary systems.

As a corollary, there are no polynomial relations among the Hodge numbers of n-dimensional smooth complex projective varieties besides the ones induced by the Hodge symmetries, which answers a question raised by Kollár in 2012.

Topological Invariants, Instantons and Chiral Anomaly on Spaces with Torsion

description: In a spacetime with nonvanishing torsion there can occur topologically stable configurations associated with the frame bundle which are independent of the curvature. The relevant topological invariants are integrals of local scalar densities first discussed by Nieh and Yan (N-Y). In four dimensions, the N-Y form $N= (T^a \wedge T_a - R_{ab} \wedge e^a \wedge e^b)$ is the only closed 4-form invariant under local Lorentz rotations associated with the torsion of the manifold. The integral of $N$ over a compact D-dimensional (Euclidean) manifold is shown to be a topological invariant related to the Pontryagin classes of SO(D+1) and SO(D). An explicit example of a topologically nontrivial configuration carrying nonvanishing instanton number proportional to $\int N$ is costructed. The chiral anomaly in a four-dimensional spacetime with torsion is also shown to contain a contribution proportional to $N$, besides the usual Pontryagin density related to the spacetime curvature. The violation of chiral symmetry can thus depend on the instanton number of the tangent frame bundle of the manifold. Similar invariants can be constructed in D>4 dimensions and the existence of the corresponding nontrivial excitations is also discussed.

description: We propose a finite element method for the numerical simulation of electroconvection of thin liquid crystals. The liquid is located in between two concentric circular electrodes which are either assumed to be of infinite height or slim. Each configuration results in a different nonlocal electro-magnetic model defined on a two dimensional bounded domain. The numerical method consists in approximating the surface charge density, the liquid velocity and pressure, and the electric potential in the two dimensional liquid region. Finite elements for the space discretization coupled with standard time stepping methods are put forward. Unlike for the infinite electrodes configuration, our numerical simulations indicate that slim electrodes are favorable for electroconvection to occur and are able to sustain the phenomena over long period of time. Furthermore, we provide a numerical study on the influence of the three main parameters of the system: the Rayleigh number, the Prandtl number and the electrodes aspect ratio.

Leonardite and biochar for mine impacted water and soils

description: Immobilization of metals using soil amendment processes is increasingly being considered as an effective and low cost remediation alternative in the mining industry. Both leonardite, a carbon-rich material rich in humic acids and biochar, an organic material that has undergone pyrolysis, have shown to adsorb heavy metals, such as Cd and Zn and promote plant growth. We examined the potential to use leonardite and biochar for metal sequestration in mining impacted water and soils, by determining their capacity to adsorb metals in water, sequester metals in tailings and promote plant growth. Biochar removed up to 95% Cd and 90% Zn from synthetic water and resulted in a 74% reduction of Cd and 18% of Zn leached from columns containing tailings. Whereas, leonardite only adsorbed 38% Cd and 29% Zn from synthetic water and resulted in column leachate with higher concentrations of heavy metals. Leonardite amendments caused decreases in pH and mobilization of metals from tailings may be due to acidification. Above and belowground growth of 2 different northern native herb species (Lupinus arcticus and Hedysarum alpinum) in amended tailings were examined. Amendments had little influence on growth with only the leonardite and lime treatment showing increased belowground biomass. This initial trial demonstrates that both amendments show potential for on-going management of contaminated waters and tailings, however, additional liming agents are likely necessary with leonardite.

description: The physical and geometrical meaning of the four parameters of Lewis metric for the Lewis class are investigated. Matching this spacetime to a completely anisotropic, rigidly rotating, fluid cylinder, we obtain from the junction conditions that the four parameters are related to the vorticity of the source. Furthermore it is shown that one of the parameters must vanish if one wishes to reduce the Lewis class to a locally static spacetime. Using the Cartan scalars it is shown that the Lewis class does not include globally Minkowski as special class, and that it is not locally equivalent to the Levi-Civita metric. Also it is shown that, in contrast with the Weyl class, the parameter responsible for the vorticity appears explicitly in the expression for the Cartan scalars. Finally, to enhance our understanding of the Lewis class, we analyse the van Stockum metric.

description: In this report, structural, electronic, magnetic and transport properties of quaternary Heusler alloys CoRuMnGe and CoRuVZ (Z = Al, Ga) are investigated. All the three alloys are found to crystallize in cubic structure. CoRuMnGe exhibits L2$_1$ structure whereas, the other two alloys have B2-type disorder. For CoRuMnGe and CoRuVGa, the experimental magnetic moments are in close agreement with the theory as well as those predicted by the Slater-Pauling rule, while for CoRuVAl, a relatively large deviation is seen. The reduction in the moment in case of CoRuVAl possibly arises due to the anti-site disorder between Co and Ru sites as well as V and Al sites. Among these alloys, CoRuMnGe has the highest T$\mathrm{_C}$ of 560 K. Resistivity variation with temperature reflects the half-metallic nature in CoRuMnGe alloy. CoRuVAl shows metallic character in both paramagnetic and ferromagnetic states, whereas the temperature dependence of resistivity for CoRuVGa is quite unusual. In the last system, $ρ$ vs. T curve shows an anomaly in the form of a maximum and a region of negative temperature coefficient of resistivity (TCR) in the magnetically ordered state. The ab initio calculations predict nearly half-metallic ferromagnetic state with high spin polarization of 91, 89 and 93 \% for CoRuMnGe, CoRuVAl and CoRuVGa respectively. To investigate the electronic properties of the experimentally observed structure, the Co-Ru swap disordered structures of CoRuMnGe alloy are also simulated and it is found that the disordered structures retain half-metallic nature, high spin polarization with almost same magnetic moment as in the ideal structure. Nearly half-metallic character, high T$\mathrm{_C}$ and high spin polarization make CoRuMnGe alloy promising for room temperature spintronic applications.

description: Here we present a theoretical investigation of the Floquet spectrum in multiterminal quantum dot Josephson junctions biased with commensurate voltages. We first draw an analogy between the electronic band theory and superconductivity which enlightens the time-periodic dynamics of the Andreev bound states. We then show that the equivalent of the Wannier-Stark ladders observed in semiconducting superlattices via photocurrent measurements, appears as specific peaks in the finite frequency current fluctuations of superconducting multiterminal quantum dots. In order to probe the Floquet-Wannier-Stark ladder spectra, we have developed an analytical model relying on the sharpness of the resonances. The charge-charge correlation function is obtained as a factorized form of the Floquet wave-function on the dot and the superconducting reservoir populations. We confirm these findings by Keldysh Green's function calculations, in particular regarding the voltage and frequency dependence of the resonance peaks in the current-current correlations. Our results open up a road-map to quantum correlations and coherence in the Floquet dynamics of superconducting devices.

The size of the potential is chosen so that the large, highly oscillatory, random field is producing non-trivial effects in the asymptotic limit. We prove either homogenization, i.e., the random potential is replaced by some deterministic constant, or convergence to a stochastic partial differential equation, i.e., the random potential is replaced by some stochastic noise, depending on the correlation property. When the limit is deterministic, we provide estimates of the error between the heterogeneous and homogenized solutions when certain mixing assumption of the random potential is satisfied. We also prove a central limit type of result when the random potential is Gaussian or Poissonian. Lower dimensional and time-dependent cases are also treated. Most of the ingredients in the analysis are probabilistic, including a Feynman-Kac representation, a Brownian motion in random scenery, the Kipnis-Varadhan's method, and a quantitative martingale central limit theorem.

description: Neutrino interactions beyond the Standard Model (BSM) are theoretically well motivated and have an important impact on the future precision measurement of neutrino oscillation. In this work, we study the sensitivity of a multi-ton-scale liquid Xenon dark matter detector equipped with an intense radiative neutrino source to various BSM neutrino-electron interactions. We consider the conventional Non-Standard Interactions (NSIs), other more generalized four-fermion interactions including scalar and tensor forms, and light-boson mediated interactions. The work shows that with realistic experimental setups, one can achieve unprecedented sensitivity to these BSM neutrino-electron interactions.

description: Cet article donne une histoire de la vallée de I'Oker. Les terrasses de la vallée sont datées par les formes de la solifluction, de la cryoturbation et les vallées dissymetriques et des formes éoliennes. On distingue une Terrasse Moyenne, formée par l'accumulation rissienne, une Basse-Terrasse supérieur, formée par l'accumulution würmienne, et une Basse-Terrasse inférieur dégagée par l'érosion tardiglaciale. Aujourd'hui la Basse-Terrasse inférieur est couverte par des alluvions limoneuses. Elles se sont probablement formées seulement depuis la déforestation par l'homme. L'Oker conflue dans l'Aller. Les terrasses de l'Oker convergent entre elles et se raccordent avec le fond de la vallée de l'Aller (Urstromtal). Ce fait prouve l'origine climatique de l'érosion tardiglaciaire.

description: Consider the space B of complex $p\times q$ matrces with norm <1. There exists a standard one-parameter family $S_a$ of unitary representations of the pseudounitary group U(p,q) in the space of holomorphic functions on B (i.e. scalar highest weight representations). Consider the restriction $T_a$ of $S_a$ to the pseudoorthogonal group O(p,q). The representation of O(p,q) in $L^2$ on the symmetric space $O(p,q)/O(p)\times O(q)$ is a limit of the representations $T_a$ in some precise sence. Spectrum of a representation $T_a$ is comlicated and it depends on $α$. We obtain the complete Plancherel formula for the representations $T_a$ for all admissible values of the parameter $α$. We also extend this result to all classical noncompact and compact Riemannian symmetric spaces.

description: We study the geometry and cohomology of semiample hypersurfaces in toric varieties. Such hypersurfaces generalize the MPCP-desingularizations of Calabi-Yau ample hypersurfaces in the Batyrev mirror construction. We study the topological cup product on the middle cohomology of semiample hypersurfaces. In particular, we obtain a complete algebraic description of the middle cohomology of regular semiample hypersurfaces in 4-dimensional simplicial toric varieties what would be interesting for physics.

description: We consider two exact solutions of Einstein's field equations corresponding to a cylinder of dust with net zero angular momentum. In one of the cases, the dust distribution is homogeneous, whereas in the other, the angular velocity of dust particles is constant [1]. For both solutions we studied the junction conditions to the exterior static vacuum Levi-Civita spacetime. From this study we find an upper limit for the energy density per unit length $σ$ of the source equal ${1\over 2}$ for the first case and ${1\over 4}$ for the second one. Thus the homogeneous cluster provides another example [2] where the range of $σ$ is extended beyond the limit value ${1\over 4}$ previously found in the literature [3,4]. Using the Cartan Scalars technics we show that the Levi-Civita spacetime gets an extra symmetry for $σ={1\over 2}$ or ${1\over 4}$. We also find that the cluster of homogeneous dust has a superior limit for its radius, depending on the constant volumetric energy density $ρ_0$.
Graceful Exit and Energy Conditions in String Cosmology

description: String cosmology solutions are examined in a generalized phase-space including sources representing arbitrary corrections to lowest order string-dilaton-gravity effective action. We find a set of necessary conditions for a graceful exit transition from a dilaton-driven inflationary phase to a radiation dominated era. We show that sources allowing such a transition have to violate energy conditions similar to those appearing in singularity theorems of general relativity. Since familiar classical sources, excepting spatial curvature, obey these energy conditions we conclude that a generic graceful exit in string cosmology requires a new effective phase of matter. Our results clarify and generalize previous analyses and enable us to critically reexamine proposed non-singular cosmologies.

description: We study the Dyson rank function $N(r,t;n)$, the number of partitions with rank congruent to $r$ modulo $t$. We first show that it is monotonic in $n$, and then show that it equidistributed as $n \rightarrow \infty$. Using this result we prove a conjecture of Hou and Jagadeeson on the convexity of $N(r,t;n)$.

description: Forty years ago E. Altenkirch had developed a theory concerning the use of the electrothermic Peltier effect for refrigerating purposes. This theory is too much simplified in comparison with the practical difficulties and the present authors give a more detailed calculation here. First they consider the influence of non cylindric forms of the thermoelements. Secondly the new calculations demonstrate the great influence even of small contact resistances on the maximal temperature diminuition and efficiency of electrothermic cooling plants. In conclusion the authors discuss the diminuition of the practical chances of the electrothermic cooling method from the standpoint of the new detailed theory.
Pro-p-Iwahori-Hecke Algebras in the mod-p Local Langlands Program

Publisher: name: Columbia University
Year: 2014
Subjects: subject: Mathematics
subject: FOS: Mathematics

description: Let p be a prime number, and F a nonarchimedean local field of residual characteristic p. This thesis is dedicated to the study of the pro-p-Iwahori-Hecke algebra H_{F_p}(G, I(1)) in the mod-p Local Langlands Program, where G is the group of F-points of a connected, reductive group, and I(1) is a pro-p-Iwahori subgroup of G.
      When G = U(2,1)(E/F) is an unramified unitary group in three variables, we first describe the structure and simple modules of the algebra H_{F_p}(G, I(1)). We then adapt methods of Schneider-Stuhler and Paskunas to construct, for each supersingular H_{F_p}(G, I(1))-module, a supersingular representation of G. These are exactly the representations which are expected to correspond to irreducible Galois parameters.
      When G = U(1,1)(Q_{p^2} /Q_p) is an unramified unitary group in two variables, we use the pro-p-Iwahori-Hecke algebra H_{F_p}(G_S , I_S(1)) of the derived subgroup G_S to classify the supersingular representations of G. Combining this with previous results, we obtain a classification of all irreducible representations of G, and then construct a correspondence between representations of G and Galois parameters.
      Finally, when G = GL_n(F) and G_S = SL_n(F), we show how to relate the two algebras H_{F_p}(G, I(1)) and H_{F_p}(G_S, I_S(1)). Using this interplay, we prove a numerical correspondence between L-packets of supersingular H_{F_p}(G_S , I_S(1))-modules and irreducible projective n-dimensional Galois representations, and prove that this correspondence is induced by a functor when F = Q_p.

Iterated Extended Kalman Smoother-based Variable Splitting for $L_1$-Regularized State Estimation

description: In this paper, we propose a new framework for solving state estimation problems with an additional sparsity-promoting $L_1$-regularizer term. We first formulate such problems as minimization of the sum of linear or nonlinear quadratic error terms and an extra regularizer, and then present novel algorithms which solve the linear and nonlinear cases. The methods are based on a combination of the iterated extended Kalman smoother and variable splitting techniques such as alternating direction method of multipliers (ADMM). We present a general algorithmic framework for variable splitting methods, where the iterative steps involving minimization of the nonlinear quadratic terms can be computed efficiently by iterated smoothing. Due to the use of state estimation algorithms, the proposed framework has a low per-iteration time complexity, which makes it suitable for solving a large-scale or high-dimensional state estimation problem. We also provide convergence results for the proposed algorithms. The experiments show the promising performance and speed-ups provided by the methods.

description: Aluminium and copper are successfully upset-welded within a cylindric form between the melting points of aluminium and of the eutecticum, Al-Al2Cu, i. e. 548°C. The liquid eutecticum is formed through the contact of the two specimens only. The aluminium rod ends in the form of a flat hollow cone and the copper rod, as a pointed cone, is fitted into it. A ring-shaped sIot inside the press cylinder surrounds the contact lines. Under a hammer-blow the oxydefilm is torn, aluminium and the newly formed eutecticum fill the snotch. The tensile strength of the joint exceeds that of the aluminium rod.
