Positive and negative linear chirping of Gaussian pulses in non-dispersive dielectric layers
(Elsevier Science, 2020-11)
In this work, the first and second order effects for reflected and transmitted pulses with a Gaussian distribution of frequencies are analytically developed and interpreted. They show some peculiar characteristics that ...
On the far field optical properties of Ag-Au nanosphere pairs
(American Chemical Society, 2010-10)
In this work we study the far field optical properties of heterodimers composed of a silver and a gold nanosphere of the same size, by means of exact electrodynamics calculations based on the generalized multiparticle Mie ...
Historical climatic extremes as indicators for typical scenarios of Holocene climatic periods in the Pampean plain
(Elsevier Science, 2009-12)
The Holocene has been marked by two different climatic periods in the Pampas, one (8.5-3.5 kyr B.P.), characterized by temperatures and precipitation higher than today and the other (3.5-1.4 kyr B.P.) semiarid, generating ...
Cambios florísticos en comunidades de malezas: un marco conceptual basado en reglas de ensamblajeUnderstanding weed shifts by applying the assembly rules framework
(Asociación Argentina de Ecología, 2012-08)
La agricultura ofrece situaciones interesantes para estudiar la sucesión ecológica en comunidades de malezas. Existe evidencia empírica que indica que la composición florística de las comunidades de malezas se modifica ...
Experimental and theoretical study of the hydration of phosphate groups in esters of biological interest
(Pergamon-Elsevier Science Ltd, 2007-04)
We have studied the influence of different groups esterified to phosphates on the strength of the interaction of the P{single bond}O bond with one water molecule. Experimental vibrational spectra of PO43-, HPO42-, H2PO4-, ...
Automatic well tying and wavelet phase estimation with no waveform stretching or squeezing
(Society of Exploration Geophysicists, 2020-02)
Well-to-seismic tie and wavelet phase estimation are close and related steps to link geology and seismic data. Usually these processes are solved separately or alternately, diminishing the quality of the well tying procedure. ...
Evaluation of Zadoff-Chu, Kasami, and Chirp-Based encoding schemes for acoustic local positioning systems
(Institute of Electrical and Electronics Engineers, 2020-08)
The task of determining the physical coordinates of a target in indoor environments is still a key factor for many applications including people and robot navigation, user tracking, location-based advertising, augmented ...
6000 días más: evidencia neurocientífica acerca del impacto de la pobreza infantil6000 more days: Neuroscientific evidence about the impact of childhood poverty
(Elsevier Doyma Sl, 2015-12)
El estudio neurocientífico de la pobreza infantil realizado por diferentes grupos de investigación durante las últimas dos décadas ha permitido acumular evidencia que indica que el impacto de las carencias materiales y ...
A Big Data approach to forestry harvesting productivity
(Elsevier, 2019-06)
Modern industrial technology enables to collect and process large amount of data, providing valuable information for different industry activities. A representative case of this evolution is the Forest industry, since ...
Creep tide model for the three-body problem: The rotational evolution of a circumbinary planet
(EDP Sciences, 2021-07)
We present a tidal model for treating the rotational evolution in the general three-body problem with arbitrary viscosities, in which all the masses are considered to be extended and all the tidal interactions between pairs ...
