h-plots for displaying nonmetric dissimilarity matrices
Wiley Periodicals (2013-01)Nonmetric pairwise data with violations of symmetry, reflexivity, or triangle inequality appear in fields such as image matching, web mining, or cognitive psychology. When data are inherently nonmetric, we should not enforce ... -
H5P: crear, compartir, evaluar, reutilizar, etc.
Instituto Nacional de Tecnologías Educativas y de Formación del Profesorado (INTEF) (2022-06-28)Desde la introducción de las tecnologías de información y comunicaciones en el aula, una de las preocupaciones de la docencia era encontrar entornos para la creación, realización y evaluación de actividades educativas. Eso ... -
Has the balloon really burst? Analysis of “the UK-REBOA randomized clinical trial”
Elsevier (2024-08)Background: Uncontrolled hemorrhagic shock is a leading cause of early death after injury. Resuscitative endovascular balloon occlusion of the aorta (REBOA) represents a paradigm shift in achieving hemodynamic stability ... -
Heteroskedastic geographically weighted regression model for functional data
Elsevier (2020)A large number of approaches for modelling spatially dependent functional variables often assume that the functional regression coefficients are constant over the region of interest. However, in many occasions it is far ... -
Hierarchical spatial modeling of the presence of Chagas disease insect vectors in Argentina. A comparative approach
Springer Verlag (2016)We modeled the spatial distribution of the most important Chagas disease vectors in Argentina, in order to obtain a predictive mapping method for the probability of presence of the vector species. We analyzed both the ... -
Hierarchical Spatio-Temporal Change-Point Detection
Taylor and Francis (2023)1 Introduction 2 Multivariate Change-Point Detection 3 Hierarchical Spatio-Temporal Change-Point Detection 4 Numerical Evaluation 5 Real Data Analyses 6 Discussion Supplemental material Acknowledgements References ... -
High leverage detection in general functional regression models with spatially correlated errors
Wiley (2021)The presence of curves that deviate markedly from the core of a set of curves can greatly affect inference and forecasting in a functional regression model. Thus their detection is key to increase the accuracy of the ... -
High order integrators obtained by linear combinations of symmetric-conjugate compositions
Elsevier (2022-02-01)A new family of methods involving complex coefficients for the numerical integration of differential equations is presented and analyzed. They are constructed as linear combinations of symmetric-conjugate compositions ... -
High precision Symplectic Integrators for the Solar System
Springer Netherlands (2013-02)Using a Newtonian model of the Solar System with all 8 planets, we perform extensive tests on various symplectic integrators of high orders, searching for the best splitting scheme for long term studies in the Solar System. ... -
High-order commutator-free quasi-Magnus exponential integrators for non-autonomous linear evolution equation
Elsevier (2017-11)The class of commutator-free quasi-Magnus (CFQM) exponential integrators provides a favourable alternative to standard Magnus integrators, in particular for large-scale applications arising in the time integration of ... -
High-order Hamiltonian splitting for the Vlasov–Poisson equations
Springer Verlag (2017)We consider the Vlasov–Poisson equation in a Hamiltonian framework and derive new time splitting methods based on the decomposition of the Hamiltonian functional between the kinetic and electric energy. Assuming smoothness ... -
Highly tempering infinite matrices
Springer Milan (2017-02)In this short note, it is proved the existence of in nite matrices that not only preserve convergence and limits of sequences but also convert every mem- ber of some dense vector space consisting, except for zero, of ... -
Hilbert regularity of Z-graded modules over polynomial rings
Rocky Mountain Mathematics Consortium (2017-06)Let M be a finitely generated Z-graded module over the standard graded polynomial ring R=K[X1,…,Xd] with K a field, and let HM(t)=QM(t)/(1−t)d be the Hilbert series of~M. We introduce the Hilbert regularity of~M as the ... -
Hilbert series of modules over positively graded polynomial rings
Elsevier (2016-08)In this note, we give examples of formal power series satisfying certain conditions that cannot be realized as Hilbert series of finitely generated modules. This answers to the negative a question raised in a recent article ... -
Hippocampal shape analysis in Alzheimer’s disease using Functional Data Analysis
Wiley-Blackwell (2013)The hippocampus is one of the first affected regions in Alzheimer's disease. The left hippocampi of control subjects, patients with mild cognitive impairment and patients with Alzheimer's disease are represented by spherical ... -
Homogenization in compiling ICRF combined catalogs
EDP Sciences (2013)Context. The International Astronomical Union (IAU) recommendations regarding the International Celestial Reference Frame (ICRF) realizations require the construction of radio sources catalogs obtained using very-long-baseline ... -
Homomorphic encoders of profinite abelian groups I
Elsevier (2023-05)Let {Gi |i ∈ N} be a family of finite Abelian groups. We say that a subgroup G ≤ i∈N Gi is order controllable if for every i ∈ N there is ni ∈ N such that for each c ∈ G, there exists a ∈ G satisfying that a|[1,i] = ... -
Homomorphic Encoders of Profinite Abelian Groups II
MDPI (2022-03-29)Let {Gi:i∈N} be a family of finite Abelian groups. We say that a subgroup G≤∏i∈NGi is order controllable if for every i∈N, there is ni∈N such that for each c∈G, there exists c1∈G satisfying c1|[1,i]=c|[1,i], supp(c1)⊆[1,ni], ... -
How to compute the Stanley depth of a module
American Mathematical Society (2017)In this paper we introduce an algorithm for computing the Stanleydepth of a finitely generated multigraded module M over the polynomialring K[X1,...,Xn]. As an application, we give an example of a module whoseStanley depth ... -
Hölder regularity for the Moore-Gibson-Thompson equation with infinite delay
American Institute of Mathematical Sciences (AIMS) (2018-01)We characterize the well-posedness of a third order in time equation with infinite delay in Holder spaces, solely in terms of spectral properties concerning the data of the problem. Our analysis includes the case of the ...
