Testing for the equality of k regression curves
(Academia Sinica, Institute of Statistical Science, 2007)Assume that (Xj , Yj ) are independent random vectors satisfying the nonparametric regression models Yj = mj (Xj ) + σj (Xj )εj , for j = 1, . . . , k, where mj (Xj ) = E(Yj Xj ) and σ 2 j (Xj ) = Var (Yj Xj ) are ... 
Testing in generalized partially linear models: A robust approach
(Elsevier, 2013)In this paper, we introduce a family of robust statistics which allow to decide between a parametric model and a semiparametric one. More precisely, under a generalized partially linear model, i.e., when the observations ... 
The DDGclassifier in the functional setting
(Springer, 2017)The maximum depth classifier was the first attempt to use data depths instead of multivariate raw data in classification problems. Recently, the DDclassifier has addressed some of the serious limitations of this classifier ... 
The eigenvalue characterization for the constant sign Green’s functions of (k,n−k)(k,n−k) problems
(Springer International Publishing, 20160211)This paper is devoted to the study of the sign of the Green’s function related to a general linear nthorder operator, depending on a real parameter, Tn[M]Tn[M], coupled with the (k,n−k)(k,n−k) boundary value conditions. If ... 
The impact of immigration and vaccination in reducing the incidence of hepatitis B in Catalonia (Spain)
(BioMed Central, 2012)Background The Hepatitis B virus (HBV) infection is a major cause of liver disease and liver cancer worldwide according to the World Health Organization. Following acute HBV infection, 15% of infected healthy adults and ... 
The importance of interlinguistic similarity and stable bilingualism when two languages compete
(IOP Publishing, 2011)One approach for analyzing the dynamics of two languages in competition is to fit historical data for the number of speakers of each with a mathematical model in which the parameters are interpreted as the similarity between ...

The Monotone Iterative Technique for ThreePoint SecondOrder Integrodifferential Boundary Value Problems with pLaplacian
(Springer, 2007)A monotone iterative technique is applied to prove the existence of the extremal positive pseudosymmetric solutions for a threepoint secondorder pLaplacian integrodifferential boundary value problem. 
The number of reduced alignments between two DNA sequences
(BioMed Central, 2014)Background In this study we consider DNA sequences as mathematical strings. Total and reduced alignments between two DNA sequences have been considered in the literature to measure their similarity. Results for explicit ... 
Twin Hypercube for Intuitionistic Fuzzy Sets and Their Application in Medicine
(Etamaths Publishing, 2017)In this paper, we present a description of intuitionistic fuzzy sets as vectors in twin hypercube. Finally we verify an application of intuitionistic fuzzy sets in medicine using twin hypercube for intuitionistic fuzzy sets. 
Validation of an AutoRegressive Integrated Moving Average model for the prediction of animal zone temperature in a weaned piglet building
(Elsevier, 2018)An AutoRegressive Integrated Moving Average model was validated for the prediction of temperatures in the animal zone of conventional weaned piglet barn. The validation period covered seven cycles and recorded values at ... 
A Viral Infection Model with a Nonlinear Infection Rate
(SpringerOpen, 2009)A viral infection model with a nonlinear infection rate is constructed based on empirical evidences. Qualitative analysis shows that there is a degenerate singular infection equilibrium. Furthermore, bifurcation of cusptype ...
