Can environmental constraints determine random patterns of plant species co-occurrence?
(John Wiley & Sons Ltd., 2015-02-13)Plant community ecologists use the null model approach to infer assembly processes from observed patterns of species co-occurrence. In about a third of published studies, the null hypothesis of random assembly cannot be ... -
Central limit theorems for directional and linear random variables with applications
(Academia Sinica, Institute of Statistical Science, 2015)A central limit theorem for the integrated squared error of the directional-linear kernel density estimator is established. The result enables the construction and analysis of two testing procedures based on squared loss: ... -
Characterization of constant sign Green's function for a two-point boundary-value problem by means of spectral theory
(Texas State University, Department of Mathematics, 2017)This article is devoted to the study of the parameter’s set where the Green’s function related to a general linear nth-order operator, depending on a real parameter, Tn[M], coupled with many different two point boundary value ... -
Chronicle of an early demise, surname extinction in the fifteenth and the seventeenth centuries
(Taylor & Francis, 2018)It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article analyzes the evolution and ... -

A circular nonhomogeneous hidden Markov field for the spatial segmentation of wildfire occurrences
(Wiley, 2019)Motivated by studies of wildfire seasonality, we propose a nonhomogeneous hidden Markov random field to model the spatial distribution of georeferenced fire occurrences during the year, by representing occurrence times as ... -
A Clustering Perspective of the Collatz Conjecture
(MDPI, 2021)This manuscript focuses on one of the most famous open problems in mathematics, namely the Collatz conjecture. The first part of the paper is devoted to describe the problem, providing a historical introduction to it, as ... -
Compression–Expansion Fixed Point Theorems for Decomposable Maps and Applications to Discontinuous ϕ-Laplacian problems
(Springer, 2021)In this paper, we prove new compression–expansion type fixed point theorems in cones for the so-called decomposable maps, that is, compositions of two upper semicontinuous multivalued maps. As an application, we obtain ... -
Computation of Green’s functions through algebraic decomposition of operators
(Springer International Publishing, 2016-09-13)In this article, we use linear algebra to improve the computational time for obtaining Green’s functions of linear differential equations with reflection (DER). This is achieved by decomposing both the ‘reduced’ equation ... -
Constant sign solution for a simply supported beam equation
(University of Szeged, 2017)The aim of this paper is to ensure the existence of constant sign solutions for the fourth order boundary value problem. This problem models the behavior of a suspension bridge assuming that the vertical displacement ... -
Constant Sign Solutions to Linear Fractional Integral Problems and Their Applications to the Monotone Method
(MDPI, 2020)This manuscript provides some results concerning the sign of solutions for linear fractional integral equations with constant coefficients. This information is later used to prove the existence of solutions to some ... -
Controllability of nonlinear fractional delay dynamical systems with prescribed controls
(Vilnius University Press, 2018)In this paper, we consider controllability of nonlinear fractional delay dynamical systems with prescribed controls. We firstly give the solution representation of the fractional delay dynamical systems using Laplace ... -

Cytokine-based Predictive Models to Estimate the Probability of Chronic Periodontitis: Development of Diagnostic Nomograms
(Springer Nature, 2017-10-14)Although a distinct cytokine profile has been described in the gingival crevicular fluid (GCF) of patients with chronic periodontitis, there is no evidence of GCF cytokine-based predictive models being used to diagnose the ... -
Determining optimum wavelengths for leaf water content estimation from reflectance: A distance correlation approach
(Elsevier, 2018)This paper proposes a method to estimate leaf water content from reflectance in four commercial vineyard varieties by estimating the local maxima of a distance correlation function. First, it applies four different functional ... -
Dimensionalidade da capacidade económica nas comarcas galegas
(Universidade de Santiago de Compostela, 2000)Neste artigo o obxectivo xeral que se establece é realizar unha análise exploratoria dun conxunto suficientemente amplo de variables que, nun primeiro momento, están relacionadas coa capacidade económica a nivel comarcal. ... -
Displacement Calculus
(MDPI, 2020)In this work, we establish a theory of Calculus based on the new concept of displacement. We develop all the concepts and results necessary to go from the definition to differential equations, starting with topology and ... -
Dissipativity of Fractional Navier–Stokes Equations with Variable Delay
(MDPI, 2020)We use classical Galerkin approximations, the generalized Aubin–Lions Lemma as well as the Bellman–Gronwall Lemma to study the asymptotical behavior of a two-dimensional fractional Navier–Stokes equation with variable ... -
DTDA: An R Package to Analyze Randomly Truncated Data
(Foundation for Open Access Statistics, 2010)In this paper, the R package DTDA for analyzing truncated data is described. This package contains tools for performing three different but related algorithms to compute the nonparametric maximum likelihood estimator of ... -
Dynamic Analysis of a Two-Language Competitive Model with Control Strategies
(Hindawi Publishing, 2013)The dynamic behavior of a two-language competitive model is analyzed systemically in this paper. By the linearization and the Bendixson-Dulac theorem on dynamical system, some sufficient conditions on the globally asymptotical ...
