Inequality between size and angular momentum for bodies
(20140131)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 ... 
Effect of the microtubuleassociated protein tau on dynamics of singleheaded motor proteins KIF1A
(201402)Intracellular transport based on molecular motors and its regulation are crucial to the functioning of cells. Filamentary tracks of the cells are abundantly decorated with nonmotile microtubuleassociated proteins, such ... 
The BrauerPicard group of the representation category of finite supergroup algebras
(2014)We develop further the techniques presented in a previous article (M. Mombelli. Abh. Math. Semin. Univ. Hamb. 82 (2012), 173–192), to study bimodule categories over the representation categories of arbitrary finitedimensional ... 
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 ... 
Singleparameter spinpumping in driven metallic rings with spinorbit coupling
(2014)We consider the generation of a pure spincurrent at zero bias voltage with a single timedependent potential. To such end we study a device made of a mesoscopic ring connected to electrodes and clarify the interplay between ... 
Nonmodal linear stability of the Schwarzschild black hole
(2014)A proof is given that the space L of solutions of the linearized vacuum Einstein equation around a Schwarzschild black hole is parametrized by two scalar fields, which are gauge invariant combinations of perturbed algebraic ... 
The generalization complexity measure for continuous input data
(2014)We introduce in this work an extension for the generalization complexity measure to continuous input data. The measure, originally defined in Boolean space, quantifies the complexity of data in relationship to the prediction ... 
Characterization, definability and separation via saturated models
(2014)Three important results about the expressivity of a modal logic L are the Characterization Theorem (that identifies a modal logic L as a fragment of a better known logic), the Definability theorem (that provides conditions ... 
Completeness in hybrid type theory
(2014)We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkinstyle completeness proofs even when the modal logic being hybridized is higherorder. The key ideas are ... 
Study of the characteristic parameters of the normal voices of Argentinian speakers
(2014)The voice laboratory permits to study the human voices using a method that is objective and noninvasive. In this work, we have studied the parameters of the human voice such as pitch, formant, jitter, shimmer and harmonicnoise ... 
Adaptación de un método pseudoespectral a condiciones de contorno nolibres
(2014)Se presenta la adaptación a condiciones de contorno no libres de un método pseudoespectral basado en transformada de Fourier compleja. El método se aplica a la integración numérica de las ecuaciones de OberbeckBoussinesq ... 
Study of lead levels in soils by weathering of metallic Pb bullets used in dove hunting in Córdoba, Argentina
(2014)A study of level of Pb in soils of the centernorth of the Province of Córdoba, a worldwide recognized tourist region for dove hunting, was performed in this work. The native forest of the region has a great population ... 
Geometrical guidance and trapping transition of human sperm cells
(2014)The guidance of human sperm cells under confinement in quasi2D microchambers is investigated using a purely physical method to control their distribution. Transport property measurements and simulations are performed with ... 
Strictly positive solutions for one dimensional nonlinear elliptic problems
(2014)We study the existence and nonexistence of strictly positive solutions for the elliptic problems  in a bounded open interval, with zero boundary conditions, where  is a strongly uniformly elliptic differential operator, ... 
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, ... 
Dose point kernel calculation and modelling with nuclear medicine dosimetry purposes
(2014)Monoclonal labeled antibodies are commonly used for radioimmunotherapy purposes in nuclear medicine. The procedure is based on the deposition of specific radiactivity concentrations on tumoral regions with the aim of ... 
Dosimetry optimization system and integrated software (DOSIS) : a comparison against Fluka code results over a standard phantom
(2014)Actually, dualimaging facilities allow obtainance of both mass and activity patientspecific distributions perfectly correlated, which are important to improve dose distributions estimations and radioimmunotherapy treatment ... 
Search for gravitational waves associated with gammaray bursts detected by the InterPlanetary Network
(2014)We present the results of a search for gravitational waves associated with 223 γray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 20052010 during LIGO´s fifth and sixth science runs and Virgo´s first, ... 
Spherical functions of fundamental Ktypes associated with the ndimensional sphere
(2014)In this paper, we describe the irreducible spherical functions of fundamental Ktypes associated with the pair (G, K) = (SO(n + 1), SO(n)) in terms of matrix hypergeometric functions. The output of this description is that ... 
Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGOVirgo data from 20052010
(2014)We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ...
