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 ... -
Decay bounds for nonlocal evolution equations in Orlicz spaces
(2016)We show decay bounds of the form ∫Rd φ(u (x, t)) dx ≤ Ct−μ for integrable and bounded solutions to the nonlocal evolution equation ut(x, t) = ∫Rd J(x, y)G(u(y, t) − u(x, t))(u(y, t) − u(x, t)) dy + f (u(x, t)). Here G is ... -
Depth distribution of martensite in plasma nitrided AISI H13 steel and its correlation to hardness
(2015)The depth distributions of hardness, nitrogen, and crystallographic phases in the diffusion zone of plasma nitrided AISI H13 steel were determined by microindentation, electron microprobe, grazing incidence X-ray diffraction, ... -
Directed search for gravitational waves from Scorpius X-1 with initial LIGO data
(2015)We present results of a search for continuously emitted gravitational radiation, directed at the brightest low-mass x-ray binary, Scorpius X-1. Our semicoherent analysis covers 10 days of LIGO S5 data ranging from 50–550 ... -
Dissolution properties, solid-state transformation and polymorphic crystallization: progesterone case study
(2014)Progesterone is a natural steroid hormone and a poor soluble drug which presents two polymorphs (forms 1 and 2). Different methods to obtain form 2 were tested and a complete solid-state characterization of both polymorphs ... -
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 ... -
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, dual-imaging facilities allow obtainance of both mass and activity patient-specific distributions perfectly correlated, which are important to improve dose distributions estimations and radioimmunotherapy treatment ... -
Dynamic characterization of crystalline and glass phases of deuterated 1,1,2,2 tetrachloroethane
(2015)A thorough characterization of the γ, β, and glass phases of deuterated 1,1,2,2 tetrachloroethane (C2D2Cl4) via nuclear quadrupole resonance and Molecular Dynamic Simulations (MDSs) is reported. The presence of molecular ... -
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 ... -

(2014)Este artículo tiene como objetivo presentar hallazgos de una investigación referida a la enseñanza de saberes matemáticos en la modalidad de Educación Permanente de Jóvenes y Adultos. Este estudio tuvo como objeto analizar ... -
Effect of the microtubule-associated protein tau on dynamics of single-headed motor proteins KIF1A
(2014-02)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 microtubule-associated proteins, such ... -
Effects of magnetic field gradients on the aggregation dynamics of colloidal magnetic nanoparticles
(2015)We have used low-field 1H nuclear-magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) to investigate the aggregation dynamics of magnetic particles in ionic ferrofluids (IFFs) in the presence of magnetic field ... -
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 ... -
Empoderamiento : una caracterización al interior de la educación matemática
(2016)El presente trabajo pone en juego un proceso analítico-constructivo con el fin de realizar una caracterización del empoderamiento para el ámbito de la educación matemática. Para llegar a tal caracterización se delimitan ... -
Enhancement of dissolution rate of furosemide using a solid dispersion with D-glucosamine HCl
(2016)Furosemide is a potent high ceiling (loop) diuretic mainly used in the treatment of edematous states associated with cardiac, renal, and hepatic failure, and the treatment of hypertension. Furosemide has been classified ... -
