A methodology to determine natural radioactivity by γ spectrometry without using calibrated standard samples
(2017)When determining the radioactivity in materials by γ spectra, different processes are involved difficulting the fit. Besides, calibrated standard samples are necessary. In this work we propose a methodology to determine ... -
Una mirada sobre el operativo aprender
(2017)El artículo presenta algunas reflexiones en torno al operativo de evaluación "Aprender". -
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 ... -
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 ... -
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 ... -
SiNaRaMe : integración de una red de radares hidro-meteorológicos en latinoamérica
(2017)Pocos países en Latinoamérica poseen radares meteorológicos operativos y, menos aún, han logrado la integración de estos mediante una red, junto a otros instrumentos y sensores remotos para monitoreo hidro-meteorológico. ... -
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 ... -
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 ... -
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 ...
