    Este estudio descriptivo tiene como objetivo analizar las estrategias de traducción de las referencias culturales en los subtítulos (francés-español) de la pelicula de animación de sombras chinas en 3D Los cuentos de la noche (2011) del escritor y director francés Michel Ocelot. El film conjuga las siluetas de los personajes con el relieve tridimensional en color lo que facilita la lectura de los subtitulos que reflejan una gran diversidad de estrategias de traducción de referencias culturales.Universidad de Málaga.

    Hasse-Schmidt Derivations and Coefficient Fields in Positive Characteristics

    We show how to express any Hasse-Schmidt derivation of an algebra in terms of a finite number of them under natural hypothesis. As an application, we obtain coefficient fields of the completion of a regular local ring of positive characteristic in terms of Hasse-Schmidt derivationsComment: 14 pages; A gap in the statement of Proposition (2.7) has been fixed and the proof of Theorem (3.14) has been adapte

    Nominally forbidden transitions in the interband optical spectrum of quantum dots

    We calculate the excitonic optical absorption spectra of (In,Ga)As/GaAs self-assembled quantum dots by adopting an atomistic pseudopotential approach to the single-particle problem followed by a configuration-interaction approach to the many-body problem. We find three types of allowed transitions that would be naively expected to be forbidden. (i) Transitions that are parity forbidden in simple effective mass models with infinite confining wells (e.g. 1S-2S, 1P-2P) but are possible by finite band-offsets and orbital-mixing effects; (ii) light-hole--to--conduction transitions, enabled by the confinement of light-hole states; and (iii) transitions that show and enhanced intensity due to electron-hole configuration mixing with allowed transitions. We compare these predictions with results of 8-band k.p calculations as well as recent spectroscopic data. Transitions in (i) and (ii) explain recently observed satellites of the allowed P-P transitions.Comment: Version published in Phys. Rev.

    On the logarithmic comparison theorem for integrable logarithmic connections

    Full text link
    Let XX be a complex analytic manifold, DXD\subset X a free divisor with jacobian ideal of linear type (e.g. a locally quasi-homogeneous free divisor), j:U=XDXj: U=X-D \to X the corresponding open inclusion, EE an integrable logarithmic connection with respect to DD and LL the local system of the horizontal sections of EE on UU. In this paper we prove that the canonical morphisms between the logarithmic de Rham complex of E(kD)E(kD) and RjLR j_* L (resp. the logarithmic de Rham complex of E(kD)E(-kD) and j!Lj_!L) are isomorphisms in the derived category of sheaves of complex vector spaces for k0k\gg 0 (locally on XX)Comment: Terminology has changed: "linear jacobian type" instead of "commutative differential type"); no Koszul hypothesis is needed in theorem (2.1.1); minor changes.

    An apparatus for characterizing the magnetic field of a device under test is discussed. The apparatus is comprised of five separate devices: (1) a device for nullifying the ambient magnetic fields in a test environment area with a constant applied magnetic field; (2) a device for rotating the device under test in the test environment area; (3) a device for sensing the magnetic field (to obtain a profile of the magnetic field) at a sensor location which is along the circumference of rotation; (4) a memory for storing the profiles; and (5) a processor coupled to the memory for characterizing the magnetic field of the device from the magnetic field profiles thus obtained

    Dependence of the electronic structure of self-assembled InGaAs/GaAs quantum dots on height and composition

    Full text link
    While electronic and spectroscopic properties of self-assembled In_{1-x}Ga_{x}As/GaAs dots depend on their shape, height and alloy compositions, these characteristics are often not known accurately from experiment. This creates a difficulty in comparing measured electronic and spectroscopic properties with calculated ones. Since simplified theoretical models (effective mass, k.p, parabolic models) do not fully convey the effects of shape, size and composition on the electronic and spectroscopic properties, we offer to bridge the gap by providing accurately calculated results as a function of the dot height and composition. Prominent results are the following. (i) Regardless of height and composition, the electron levels form shells of nearly degenerate states. In contrast, the hole levels form shells only in flat dots and near the highest hole level (HOMO). (ii) In alloy dots, the electrons' ``s-p'' splitting depends weakly on height, while the ``p-p'' splitting depends non-monotonically. In non-alloyed InAs/GaAs dots, both these splittings depend weakly on height. For holes in alloy dots, the ``s-p'' splitting decreases with increasing height, whereas the ``p-p'' splitting remains nearly unchaged. Shallow, non-alloyed dots have a ``s-p'' splitting of nearly the same magnitude, whereas the ``p-p'' splitting is larger. (iii) As height increases, the ``s'' and ``p'' character of the wavefunction of the HOMO becomes mixed, and so does the heavy- and light-hole character. (iv) In alloy dots, low-lying hole states are localized inside the dot. Remarkably, in non-alloyed InAs/GaAs dots these states become localized at the interface as height increases. This localization is driven by the biaxial strain present in the nanostructure.Comment: 14 pages, 12 figure
