The Latent Scale Covariogram: A Tool for Exploring the Spatial Dependence Structure of Nonnormal Responses
(Taylor and Francis Group, 2018-10-29)
When modeling spatially distributed normal responses Yi in terms of vectors xi of explanatory variables, one may fit a linear model assuming independence, and then use the empirical variogram of the residuals to determine ...

SUCRE4Kids es un proyecto que intenta fomentar la curiosidad y la vocación científica, el pensamiento computacional y la programación en el alumnado de educación secundaria, ciclos formativos y bachillerato. Enmarcado ...
Weighted Complete Graphs for Condensing Data
(Elsevier B.V., 2020-12-01)
In many real-world problems (such as industrial applications, chemistry models, social network analysis,
among others), their solution can be obtained by transforming the problem in terms of vertices and edges,
that is ...
Estimation and prediction of time-varying GARCH models through a state-space representation: a computational approach
(Taylor & Francis, 2017-06-05)
We propose a state-space approach for GARCH models with time-varying parameters able to deal with non-stationarity that is usually observed in a wide variety of time series. The parameters of the non-stationary model are ...

The Chern–Osserman inequality for minimal surfaces in a Cartan–Hadamard manifold with strictly negative sectional curvatures
(Springer Netherlands, 2014)
We state and prove a Chern–Osserman-type inequality in terms of the volume growth for minimal surfaces S which have finite total extrinsic curvature and are properly immersed in a Cartan–Hadamard manifold N with sectional ...
Assisting therapists in assessing small animal phobias by computer analysis of video-recorded sessions
(Springer, 2017)
Behavioural Avoidance Tests (BATs) are commonly used for assessing phobias. While easy to deploy, these tests have some practical difficulties. For instance, therapists have to make distance estimations that are hard to ...
Pulsed laser ablation in liquids for the production of gold nanoparticles and carbon quantum dots: from plasmonic to fluorescence and cell labelling
(IOP Publishing, 2019-12)
The synthesis of high purity ligand free nanoparticles represents one of the requirements for nanotechnology application in highly relevant fields as nanomedicine and theranostics. Laser synthesis and processing of colloids ...
Colour image denoising by eigenvector analysis of neighbourhood colour samples
(Springer, 2020-04)
Colour image smoothing is a challenging task
because it is necessary to appropriately distinguish between noise and original structures, and to smooth noise
conveniently. In addition, this processing must take into
account ...
Femtosecond-laser-irradiation-induced structural organization and crystallinity of Bi2WO6
(Nature Research, 2020)
Controlling the structural organization and crystallinity of functional oxides is key to enhancing
their performance in technological applications. In this work, we report a strong enhancement of
the structural organization ...
