In vivo EDXRF scanning analysis of human nail
(2014-09)This paper presents the results of a new technique forin vivoenergy dispersive X-rayfluorescence (EDXRF) scan analysis, applied to humanfingernails. The scan employs a specially designed EDXRF spectrometer, which allows a ... -
The index of symmetry of compact naturally reductive spaces
(2014)We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ... -
Inequality between size and angular momentum for bodies
(2014-01-31)A universal inequality that bounds the angular momentum of a body by the square of its size is presented and heuristic physical arguments are given to support it. We prove a version of this inequality, as consequence of ... -
Influence of β-cyclodextrin on the Properties of Norfloxacin Form A
(2014-12-16)Cyclodextrins are able to form host-guest complexes with hydrophobic molecules to result in the formation of inclusion complexes. The complex formation between norfloxacin form A and β-cyclodextrin was studied by exploring ... -
Initial dynamics of initial solid-liquid interface in presence of a thermal gradient
(2014)In directional solidification experiments an alloy is placed in the thermal gradient assembly and kept stationary to achieve a steady-state thermal profile. During this time an interface motion occurs that is experimentally ... -
Interfaz visual para un Autocolimador Nikon 6D mediante procesamiento de imágenes con precisión sub-píxel : un caso de estudio
(2014)Este documento tiene el objetivo de describir el potencial de una interfaz visual básica en un Autocolimador del tipo Nikon 6B/6D, para reemplazar al operario en una medición de calidad metrológica. La interfaz visual ... -
Internal dosimetry for alpha emitters radiopharmaceuticals in biological tissue studied with the FLUKA code
(2014)Nuclear medicine clinical practices for neoplasic disease diagnose and treatment are based on the incorporation of α, β and γ radiotracers and radiopharmaceuticals, which might be associated with potential damage. Thus, ... -
Interpreting natural language instructions using language, vision and behavior
(2010)We define the problem of automatic instruction interpretation as follows. Given a natural language instruc- tion, can we automatically predict what an instruction follower, such as a robot, should do in the environment to ... -
Intrinsic angular momentum for radiating spacetimes which agrees with the Komar integral in the axisymmetric case
(2014)Here, we present a new definition of intrinsic angular momentum at future null infinity, based on the charge-integral approach. This definition is suitable for the general case of radiating spacetimes without symmetries, ... -
Inverse transition in the dipolar frustrated Ising ferromagnet : the role of domain walls
(2014)We present a theoretical study aimed at elucidating the origin of the inverse symmetry-breaking transition observed in ultrathin magnetic films with perpendicular anisotropy. We study the behavior of the dipolar frustrated ... -
Invertible bimodule categories over the representation category of a Hopf algebra
(2014-02-12)For any finite-dimensional Hopf algebra H we construct a group homomorphism BiGal (H) → BrPic(Rep(H)), from the group of equivalence classes of H-biGalois objects to the group of equivalence classes of invertible exact ... -
Irradiated graphene as a tunable Floquet topological insulator
(2014)In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge ... -
Isomorphism and disorder in o-chlorohalobenzenes studied by NQR
(2014)In this work we present experimental results that allow to characterize different solid modifications found in o-chlorohalobenzenes. Three disordered phases have been found in o-chlorobromobenzene. The stable phase at ... -
Kerma and photons absorbed-dose from Ir-192 HDR seeds
(2014)Precise calculations of absorbed dose (AD) are a difficult task involving physical phenomena such as emission, transport, and absorption of radiation. We used the Monte Carlo method to calculate Kerma as well as AD in water ... -
Landau-Zener and Rabi oscillations in the spin-dependent conductance
(2014)We describe the spin-dependent quantum conductance in a wire where a magnetic field is spatially modulated. The changes in direction and intensity of the magnetic field acts as a perturbation that mixes spin projections. ... -
Lifting via cocycle deformation
(2014)We develop a strategy to compute all liftings of a Nichols algebra over a finite dimensional cosemisimple Hopf algebra. We produce them as cocycle deformations of the bosonization of these two. In parallel, we study the ... -
Lightning in Western Patagonia
(2014)On the basis of 8 years (2005-2012) of stroke data from the World Wide Lightning Location Network we describe the spatial distribution and temporal variability of lightning activity over Western Patagonia. This region ... -
Magnetite NPs@C with highly-efficient peroxidase-like catalytic activity as an improved biosensing strategy for selective glucose detection
(2014)This work reports the novel application of carbon-coated magnetite nanoparticles (mNPs@C) as catalytic nanomaterial included in a composite electrode material (mNPs@C/CPE) taking advantages of their intrinsic peroxidase-like ... -
Magnitude modelling of HRTF using principal component analysis applied to complex values
(2014)Principal components analysis (PCA) is frequently used for modelling the magnitude of the head related transfer functions (HRTFs). Assuming that the HRTFs are minimum phase systems, the phase is obtained from the Hilbert ... -
Memory and long-range correlations in chess games
(2014)In this paper we report the existence of long-range memory in the opening moves of a chronologically ordered set of chess games using an extensive chess database. We used two mapping rules to build discrete time series and ...
