The fractal organization of ultradian rhythms in avian behavior
(2017)Living systems exhibit non-randomly organized biochemical, physiological, and behavioral processes that follow distinctive patterns. In particular, animal behavior displays both fractal dynamics and periodic rhythms yet ... -
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
(2017)Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ... -
Un camino hacia la derivada : secuencia de actividades para construir el concepto de velocidad instantánea empleando la velocidad media
(2017)La siguiente propuesta tiene por objetivo introducir conceptos básicos del análisis diferencial. Está destinada a estudiantes de los últimos años de nivel secundario, de nivel terciario o de los primeros años de nivel ... -
d-Dimensional KPZ equation as a stochastic gradient flow in an evolving landscape : interpretation and time evolution of its generating functional
(2017)The deterministic KPZ equation has been recently formulated as a gradient flow. Its non-equilibrium analog of a free energy—the “non-equilibrium potential” Φ[h], providing at each time the landscape where the stochastic ... -
Positivity results for indefinite sublinear elliptic problems via a continuity argument
(2017)We establish a positivity property for a class of semilinear elliptic problems involving indefinite sublinear nonlinearities. Namely, we show that any nontrivial nonnegative solution is positive for a class of problems the ... -
Distinguishability notion based on Wootters statistical distance : application to discrete maps
(2017)We study the distinguishability notion given by Wootters for states represented by probability density functions. This presents the particularity that it can also be used for defining a statistical distance in chaotic ... -
Effects of rainfall on Culex mosquito population dynamics
(2017)The dynamics of a mosquito population depends heavily on climatic variables such as temperature and precipitation. Since climate change models predict that global warming will impact on the frequency and intensity of ... -
Very fast dissolving acid carboxymethylcellulose-rifampicin matrix : development and solid-state characterization
(2017)One of the main obstacles to the successful treatment of tuberculosis is the poor and variable oral bioavailability of rifampicin (RIF), which is mainly due to its low hydrophilicity and dissolution rate. The aim of this ... -
Selección de parcelas control para estudios de la dinámica post-incendio : desempeño de rutinas no paramétricas y autorregresivas
(2017)Los regímenes naturales de incendios han sufrido modificaciones; consecuentemente, es indispensable disponer de herramientas robustas para el seguimiento post-fuego de la vegetación. Los satélites de alta resolución temporal ... -
Estudio experimental del efecto de la turbulencia sobre el espectro de tamaño de gotas de nube
(2017)El propósito de este trabajo es estudiar empíricamente el efecto sobre el espectro de tamaños de gotas en una nube cálida, sometida a perturbaciones que afectan el movimiento de la parcela de aire en donde se encuentra. ... -
Una mirada sobre el operativo aprender
(2017)El artículo presenta algunas reflexiones en torno al operativo de evaluación "Aprender". -
Problem of quantifying quantum correlations with non-commutative discord
(2017)In this work we analyze a non-commutativity measure of quantum correlations recently proposed by Y. Guo [Sci. Rep. 6, 25241 (2016)]. By resorting to a systematic survey of a two-qubit system, we detected an undesirable ... -
Structure constrained by metadata in networks of chess players
(2017)Chess is an emblematic sport that stands out because of its age, popularity and complexity. It has served to study human behavior from the perspective of a wide number of disciplines, from cognitive skills such as memory ... -
Unified framework to determine Gaussian states in continuous-variable systems
(2017)Gaussian states are the backbone of quantum information protocols with continuous-variable systems whose power relies fundamentally on the entanglement between the different modes. In the case of global pure states, knowledge ... -
Spherical analysis on homogeneous vector bundles of the 3-dimensional euclidean motion group
(2018)We consider R3 as a homogeneous manifold for the action of the motion group given by rotations and translations. For an arbitrary τ∈SO(3)ˆ, let Eτ be the homogeneous vector bundle over R3 associated with τ. An interesting ... -
Una experiencia vivida en aula : enseñar y aprender a trabajar con estadística desde una perspectiva crítica
(2015)En este artículo se presenta una descripción de una experiencia escolar realizada en una escuela secundaria de una localidad de la provincia de Córdoba donde la segunda autora se desempeña como profesora de matemática. La ... -
Dynamic heterogeneity in the monoclinic phase of CCl4
(2016)Carbon tetrachloride (CCl4) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuclear quadrupolar resonance (NQR) experiments ... -
Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ... -
Non-strongly isospectral spherical space forms
(2016)In this paper we describe recent results on explicit construction of lens spaces that are not strongly isospectral, yet they are isospectral on p-forms for every p. Such examples cannot be obtained by the Sunada method. ... -
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(2016)The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ...
