A Bayesian Functional Methodology for Dengue Risk Mapping in Latin America and the Caribbean
Dengue fever has become one of the most outstanding infectious diseases in the world. Besides, the incidence and prevalence of dengue are increasing in the endemic areas of the tropical and subtropical regions. Space and ... -
A Bayesian Solution to the Behrens-Fisher problem
Girón González-Torre, F. Javier; Castillo-Vázquez, Carmen
(Springer, 2021-07)
A simple solution to the Behrens–Fisher problem based on Bayes factors is presented, and its relation with the Behrens–Fisher distribution is explored. The construction of the Bayes factor is based on a simple hierarchical ... -
A class of multilinear bounded oscillation operators on measure spaces and applications.
(Springer Nature, 2023)recent years, dyadic analysis has attracted a lot of attention due to the conjecture. It has been well understood that in the Euclidean setting, Calderón–Zygmund operators can be pointwise controlled by a finite number ... -
A Class of Well-Balanced Algorithms for Relativistic Fluids on a Schwarzschild Background
LeFloch, Philippe G.; Parés-Madroñal, Carlos María; Pimentel García, Ernesto (SPRINGER, 2021-08-16)
For the evolution of a compressible fluid in spherical symmetry on a Schwarzschild curved background, we design a class of well-balanced numerical algorithms up to third-order accuracy. We treat both the relativistic ... -
A new proof of the characterization of the weighted Hardy inequality
Bernardis-Medici, Ana Lucía; Martín-Reyes, Francisco Javier; Ortega-Salvador, Pedro (Cambridge University Press, 2005)
Maz'ja and Sinnamon proved a characterization of the boundedness of the Hardy operator from Lp(v) into Lq(w) in the case 0 < q < p, 1 < p < ∞. We present here a new simple proof of the sufficiency part of that result. -
A novel embedded min-max approach for feature selection in nonlinear Support Vector Machine classification
Jiménez-Cordero, María Asunción; Morales-González, Juan Miguel; Pineda-Morente, Salvador (Elsevier, 2021)
In recent years, feature selection has become a challenging problem in several machine learning fields, such as classification problems. Support Vector Machine (SVM) is a well-known technique applied in classification ... -
A semi-implicit exactly fully well-balanced relaxation scheme for the Shallow Water Linearized Moment Equations
Caballero Cárdenas, Celia; Gómez Bueno, Irene; Del Grosso, A.; Koellermeier, J.; Morales-de-Luna, Tomás (Elsevier, 2025-01-30)
When dealing with shallow water simulations, the velocity profile is often assumed to be constant along the vertical axis. However, since in many applications this is not the case, modeling errors can be significant. Hence, ... -
A semi-implicit fully exactly well-balanced relaxation scheme for the shallow water system.
Caballero Cárdenas, Celia; Castro-Díaz, Manuel Jesús; Chalons, Christophe; Morales-de-Luna, Tomás; Muñoz-Ruiz, María de la Luz (SIAM, 2024)
This article focuses on the design of semi-implicit schemes that are fully well-balanced for the one-dimensional shallow water equations, that is, schemes that preserve all smooth steady states of the system and not just ... -
A sparse approach to mixed weak type inequalities.
(Springer Nature, 2019-12-10)Abstract. In this paper we provide some quantitative mixed weak-type estimates assuming conditions that imply that uv ∈ A∞ for Calder´on-Zygmund operators, rough singular integrals and commutators. The main novelty of ... -
A spatial functional count model for heterogeneity analysis in time
A spatial curve dynamical model framework is adopted for functional prediction of counts in a spatiotemporal logGaussian Cox process model. Our spatial functional estimation approach handles both wavelet-based heterogeneity ... -
A weighted weak-type multilinear gradient inequality
García García, Victor; Ortega-Salvador, Pedro (Springer Nature, 2025)
We characterize the weights w,v1,v2,…,vm for which the weak-type multilinear gradient inequality ‖∏i=1mfi‖p,∞;w≤C∏i=1m‖x⋅∇fi(x)‖pi,vi holds for all f1,f2,…,fm∈Cc∞(Rn) in the case 1p=1p1+1p2+⋯+1pm. -
An Arbitrary High Order Well-Balanced ADER-DG Numerical Scheme for the Multilayer Shallow-Water Model with Variable Density
Guerrero Fernández, Ernesto; Castro-Díaz, Manuel Jesús; Dumbser, Michael; Morales-de-Luna, Tomás (Springer, 2021-12-17)
In this work, we present a novel numerical discretization of a variable pressure multilayer shallow water model. The model can be written as a hyperbolic PDE system and allows the simulation of density driven gravity ... -
An enhanced heuristic framework for solving the Rank Pricing Problem
Jiménez-Cordero, María Asunción; Pineda-Morente, Salvador; Morales-González, Juan Miguel (Elsevier, 2025-03-12)
The Rank Pricing Problem (RPP) is a challenging bilevel optimization problem with binary variables whose objective is to determine the optimal pricing strategy for a set of products to maximize the total benefit, given ... -
Asymptotic properties of parameter estimates for random fields with tapered data.
Alomari, Huda Mohammed; Frías, María P.; Leonenko, Nikolai; Ruiz-Medina, María D.; Sakhno, Lyudmyla; Torres-Signes, Antoni[et al.] (Institute of Mathematical Statistics, 2017)
In this paper we present novel results on the asymptotic behavior of the so-called Ibragimov minimum contrast estimates. The case of tapered data for various models of Gaussian random fields is investigated. The CLT for ... -
Automatic feature scaling and selection for support vector machine classification with functional data.
Jiménez-Cordero, María Asunción; Maldonado-Alarcón, Sebastián (Springer Nature, 2020)
Functional Data Analysis (FDA) has become a very important field in recent years due to its wide range of applications. However, there are several real-life applications in which hybrid functional data appear, i.e., data ... -
Bergman projection and BMO in hyperbolic metric: improvement of classical result.
Rättyä, Jouni; Peláez-Márquez, José Ángel (Springer Nature, 2023)
The Bergman projection $P_\alpha$, induced by a standard radial weight, is bounded and onto from $L^\infty$ to the Bloch space $\mathcal{B}$. However, $P_\alpha: L^\infty\to \mathcal{B}$ is not a projection. This fact can ... -
