Large Deviations for the SSEP with slow boundary: the non-critical case
(2023) [Journal article]We prove a large deviations principle for the empirical measure of the one dimensional symmetric simple exclusion process in contact with reservoirs. The dynamics of the reservoirs is slowed down with respect to the dynamics ... -
Large-deviation theory for dilutedWishart random matrices
(2018) [Journal article]Wishart random matrices with a sparse or diluted structure are ubiquitous in the processing of large datasets, with applications in physics, biology, and economy. In this work, we develop a theory for the eigenvalue ... -
Large resistivity change and phase transition in the antiferromagnetic semiconductors LiMnAs and LaOMnAs
(2013) [Journal article]Antiferromagnetic semiconductors are new alternative materials for spintronic applications and spin valves. In this work, we report a detailed investigation of two antiferromagnetic semiconductors AMnAs (A = Li, LaO), which ... -
Large scale evaluation of differences between network-based and pairwise sequence-alignment-based methods of dendrogram reconstruction
(2019) [Journal article]Dendrograms are a way to represent relationships between organisms. Nowadays, these are inferred based on the comparison of genes or protein sequences by taking into account their differences and similarities. The genetic ... -
Las imágenes en los textos de física : entre el optimismo y la prudencia
(2004) [Journal article]Este trabajo se propone discutir acerca de las potencialidades y limitaciones de las imágenes externas en la Enseñanza de la Física a partir de referenciales cognitivos, y formular algunas implicaciones para el uso de ... -
Las opiniones de los profesores de física sobre el concepto de interacción en la enseñanza de la física
(2002) [Journal article]En este trabajo presentamos el análisis del contenido de entrevistas realizadas a Profesores en ejercicio de la enseñanza de la Física del nivel Polimodal. El propósito de las entrevistas estuvo ligado a indagar la importancia ... -
Las situaciones de una propuesta didáctica sobre la interación gravitatoria
(2005) [Journal article]Desde hace más de dos décadas la investigación en e nseñanza de la ciencia se viene ocupando de generar estrategias para acortar la bre cha entre los conceptos que construyen los estudiantes y los que los científicos emplean ... -
Latent ion tracks in amorphous silicon
(2013) [Journal article]We present experimental evidence for the formation of ion tracks in amorphous Si induced by swift heavy-ion irradiation. An underlying core-shell structure consistent with remnants of a high-density liquid structure was ... -

La teoría de los modelos mentales de Johnson-Laird y sus principios : una aplicación con modelos mentales de célula en estudiantes del curso de orientación universitaria
(2001) [Journal article]Previa discusión de la idoneidad como teoría de la mente adecuada explicativamente de la Teoría de los Modelos Mentales de Johnson-Laird, se presenta una investigación relativa a las representaciones mentales de célula de ... -
Late sodic metasomatism evidences in bimodal volcanic rocks of the Acampamento Velho Alloformation, Neoproterozoic III, souther Brazil
(2007) [Journal article]Um estudo mineralógico de detalhe foi realizado nas rochas vulcânicas da Aloformação Acampamento Velho nos Cerros do Bugio, Perau e Serra de Santa Bárbara (Bacia do Camaquã), sudeste do Brasil. Este evento bimodal é ... -
Late-time interacting cosmologies and the Hubble constant tension
(2022) [Journal article]In this manuscript we reassess the potential of interacting dark matter–dark energy models in solving the Hubble constant tension. These models have been proposed but also questioned as possible solutions to the H0 problem. ... -
Latex and natural rubber : recent advances for biomedical applications
(2022) [Journal article]Recently, latex (NRL) and natural rubber (NR) from Hevea brasiliensis have emerged as promising biomaterials from renewable sources for biomedical applications. Although some attempts at commercial applications have been ... -
Lattice dynamics and spin-phonon coupling in CaMn2O4 : a raman study
(2014) [Journal article]We present polarized Raman spectra of CaMn2O4 (marokite) measured in several exact scattering configurations from oriented single crystals. Most of the 11Ag + 12B1g + 10B2g + 9B3g Raman-allowed modes are identified and ... -
Lattice-gas model of a charge regulated planar surface
(2021) [Journal article]In this work, we consider a lattice-gas model of charge regulation with electrostatic interactions within the Debye–Hückel level of approximation. In addition to long-range electrostatic interactions, the model incorporates ... -
Lattice model of ionic liquid confined by metal electrodes
(2018) [Journal article]We study, using Monte Carlo simulations, the density profiles and differential capacitance of ionic liquids confined by metal electrodes. To compute the electrostatic energy, we use the recently developed approach based ... -
Lattice site investigation of F in preamorphized Si
(2007) [Journal article]The lattice location of F atoms in Si was experimentally studied. Si single crystals were amorphized, implanted with F, and afterwards the amorphous layer was recrystallized. Some of the samples prepared in this way were ... -
Lattice strain distribution resolved by X-ray Braggsurface diffraction in an Si matrix distorted by embedded FeSi2 nanoparticles
(2013) [Journal article]Out-of-plane and primarily in-plane lattice strain distributions, along the two perpendicular crystallographic directions on the subsurface of a silicon layer with embedded FeSi2 nanoparticles, were analyzed and resolved ... -
La V epistemológica aplicada a algunos enfoques en resolución de problemas
(1999) [Journal article]This paper includes a technique to apply a simplified Gowin’s Vee as a reference tool to analyse four different trends which are useful for research in Physics problem solving. They are: a) the strategy alternative; b) the ... -
Laves-phase pseudobinaries a(fe1-xbx)2 (a=zr,hf;b=al,si): some structural and magnetic properties
(1991) [Journal article]The lattice parameters and the saturation magnetization are measured for the series of intermetallic compounds A(Fe,B)2 A = Zr, Hf and B = Si and Al, with concentrations less than 15%. The magnetization measurements and ...
