Gain-switched semiconductor lasers with pulsed excitation and optical injection for dual-comb spectroscopy
Optical Society of America (2020-10-26)In this work we demonstrate the capability of two gain-switched optically injected semiconductor lasers to perform high-resolution dual-comb spectroscopy. The use of low duty cycle pulse trains to gain switch the lasers, ... -
Gait recognition from corrupted silhouettes: a robust statistical approach
Springer Verlag (2016-07)This paper introduces a method based on robust statistics to build reliable gait signatures from averaging silhouette descriptions, mainly when gait sequences are affected by severe and persistent defects. The term robust ... -
Gait-based Gender Classification Considering Resampling and Feature Selection
Engineering and Technology Publishing (2013-06)Two intrinsic data characteristics that arise in many domains are the class imbalance and the high dimensionality, which pose new challenges that should be addressed. When using gait for gender classification, benchmarking ... -
Gauss-Bonnet formulae and rotational integrals in constant curvature spaces
Elsevier (2017-02)We obtain generalizations of the main result in [10], and then provide geometric interpretations of linear combinations of the mean curvature integrals that appear in the Gauss–Bonnet formula for hypersurfaces in space ... -
Gene selection and disease prediction from gene expression data using a two-stage hetero-associative memory
Springer Verlag (2019)In general, gene expression microarrays consist of a vast number of genes and very few samples, which represents a critical challenge for disease prediction and diagnosis. This paper develops a two-stage algorithm that ... -
Generalized elastodynamic model for nanophotonics
American Physical Society (2020)A self-consistent theory for the classical description of the interaction of light and matter at the nanoscale is presented, which takes into account spatial dispersion. Up to now, the Maxwell equations in nanostructure ... -
Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit
SAGE Publications (2019)The aim of this paper is to model an ordinal response variable in terms of vector-valued functional data included on a vector-valued RKHS. In particular, we focus on the vector-valued RKHS obtained when a geometrical ... -
Generation of multifocal irradiance patterns by using complex Fresnel holograms
Optical Society of America (2018)We experimentally demonstrate Fresnel holograms able to produce multifocal irradiance patterns with micrometric spatial resolution. These holograms are assessed from the coherent sum of multiple Fresnel lenses. The utilized ... -
Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
The Optical Society (OSA) (2013-08)Different spatial distributions of optical vortices have been generated and characterized by implement- ing arrays of devil’s vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ... -
Geometric analysis of planar shapes with applications to cell deformations
International Society for Stereology (2015-07)Shape analysis is of great importance in many fields such as computer vision, medical imaging, and computational biology. In this paper we focus on a shape space in which shapes are represented by means of planar closed ... -
Geometric approach to non-relativistic quantum dynamics of mixed states
AIP Publishing LLC (2013-05)In this paper we propose a geometrization of the non-relativistic quantum mechanics for mixed states. Our geometric approach makes use of the Uhlmann's principal fibre bundle to describe the space of mixed states and as a ... -
Geoskills among academic librarians in Greece, Cyprus and Spain
Elsevier (2016)Existing literature on Geographic Information (GI) and libraries points out that American and Canadian librarians have long been aware of the intimate relationship between geospatial data and libraries. In Europe, though, ... -
Geospatial Analysis of Extreme Weather Events in Nigeria (1985–2015) Using Self-Organizing Maps
(2017)The explosion of data in the information age has provided an opportunity to explore the possibility of characterizing the climate patterns using data mining techniques. Nigeria has a unique tropical climate with two ... -
Geospatial information infrastructures to address spatial needs in health: Collaboration, challenges and opportunities
Elsevier (2013)Most health-related issues such as public health outbreaks and epidemiological threats are better understood from a spatial–temporal perspective and, clearly demand related geospatial datasets and services so that decision ... -
Geostatistical methods to identify and map spatial variations of soil salinity
Elsevier (2011-01)The problem of estimating and predicting spatial distribution of a spatial stochastic process, observed at irregular locations in space, is considered in this paper. Environmental variables usually show spatial dependencies ... -
Geostatistical mixed beta regression: a Bayesian approach
Springer Verlag (2017)This paper develops regression techniques for geostatistical data, with an emphasis in proportions mea- sured on a continuous scale. Specifically, it deals with Beta regression models with mixed effects to control the ... -
Gestión de datos geográficos en bibliotecas universitarias españolas: estado de la cuestión
CSIC (2015)Este trabajo presenta los resultados de una encuesta sobre la gestión de datos geográficos digitales en bibliotecas universitarias españolas. El objetivo de la investigación es averiguar en qué estado se encuentran las ... -
Giga-voxel multidimensional fluorescence imaging combining single-pixel detection and data fusion
Optical Society of America (2021-08-27)Time-resolved fluorescence imaging is a key tool in biomedical applications, as it allows to non-invasively obtain functional and structural information. However, the big amount of collected data introduces challenges in ... -
Glassy dynamics of two poly(ethylene glycol) derivatives in the bulk and in nanometric confinement as reflected in its inter- and intra-molecular interactions
AIP Publishing (2018-08)The inter- and intra-molecular interactions as they evolve in the course of glassy solidification are studied by broadband dielectric—and Fourier-transform infrared—spectroscopy for oligomeric derivatives of poly(ethylene ... -
Glimpse: A gaze-based measure of temporal salience
Multidisciplinary Digital Publishing Institute (2021-04-29)Temporal salience considers how visual attention varies over time. Although visual salience has been widely studied from a spatial perspective, its temporal dimension has been mostly ignored, despite arguably being of ...
