Mann iteration for monotone nonexpansive mappings in ordered CAT(0) space with an application to integral equations
(SpringerOpen, 20181211)In this paper, we establish some convergence results for a monotone nonexpansive mapping in a CAT(0) space. We prove the Δ and strong convergence of the Mann iteration scheme. Further, we provide a numerical example to ... 
Marginality and convexity in partition function form games
(Springer, 2021)In this paper an order on the set of embedded coalitions is studied in detail. This allows us to define new notions of superaddivity and convexity of games in partition function form which are compared to other proposals ... 
A medición da calidade de vida nas comarcas galegas
(Universidade de Santiago de Compostela, 2009)No presente artigo abórdase unha proposta que pretende achegar unha medida da calidade de vida das comarcas galegas desde un punto de vista socioeconómico. Con este propósito emprégase a técnica da Análise Envolvente de ... 
Minimax Estimation of the Volume of a Set Under the Rolling Ball Condition
(Taylor & Francis, 2018)We consider the problem of estimating the volume of a compact domain in a Euclidean space based on a uniform sample from the domain. We assume that the domain has a boundary with positive reach. We propose a datasplitting ... 
Mode testing, critical bandwidth and excess mass
(Springer, 2018)The identification of peaks or maxima in probability densities, by mode testing or bump hunting, has become an important problem in applied fields. For real random variables, this task has been approached in the statistical ... 
Modeling conditional reference regions: application to glycemic markers
(Wiley, 2021)Many clinical decisions are taken based on the results of continuous diagnostic tests. Usually, only the results of one single test is taken into consideration, the interpretation of which requires a reference range for ... 
Molecular Profiling of Circulating Tumour Cells Identifies Notch1 as a Principal Regulator in Advanced NonSmall Cell Lung Cancer
(Nature Publishing Group, 2016)Knowledge on the molecular mechanisms underlying metastasis colonization in NonSmall Cell Lung Cancer (NSCLC) remains incomplete. A complete overview integrating driver mutations, primary tumour heterogeneity and overt ... 
Multiple Positive Solutions for Quadratic Integral Equations of Fractional Order
(Hindawi, 2017)In this paper, the existence of multiple positive solutions for a class of quadratic integral equation of fractional order is obtained, by utilizing AveryHenderson and LeggettWilliams multiple fixed point theorems on ... 
Multiple positive solutions in the sense of distributions of singular BVPs on time scales and an application to EmdenFowler equations
(Springer Nature, 2008)This paper is devoted to using perturbation and variational techniques to derive some sufficient conditions for the existence of multiple positive solutions in the sense of distributions to a singular secondorder dynamic ... 
Multiple Positive Solutions of the Singular Boundary Value Problem for SecondOrder Impulsive Differential Equations on the HalfLine
(SpringerOpen, 2010)This paper uses a fixed point theorem in cones to investigate the multiple positive solutions of a boundary value problem for secondorder impulsive singular differential equations on the halfline. The conditions for the ... 
Multiple positive solutions to a fourthorder boundaryvalue problem
(Texas State University. Department of Mathematics, 2016)We study the existence, localization and multiplicity of positive solutions for a nonlinear fourthorder twopoint boundary value problem. The approach is based on critical point theorems in conical shells, Krasnosel’ski˘ı’s ... 
Necessary and sufficient conditions for the existence of nonconstant solutions generated by impulses of second order BVPs with convex potential
(University of Szeged, 2018)This paper concerns solutions generated by impulses for a class of second order BVPs with convex potential. Necessary and sufficient conditions for the existence of nonconstant solutions are derived via variational methods ... 
A new formula to get sharp global stability criteria for onedimensional discretetime models
(Springer, 20190110)We present a new formula that makes it possible to get sharp global stability results for onedimensional discretetime models in an easy way. In particular, it allows to show that the local asymptotic stability of a ... 
A new method for analysing and representing ground temperature variations in cold environments. The Fuegian Andes, Tierra del Fuego, Argentina
(Universidad de La Rioja, 2018)The thermal response of soils in cold environments has been investigated in numerous studies. The data considered here were obtained in a study carried out in Tierra del Fuego, Argentina, as part of the IV International Polar ... 
A new twophase heuristic for a problem of food distribution with compartmentalized trucks and trailers
(Wiley, 2021)This paper presents a new formulation for the routing problem in which the available fleet consists of trucks and trailers divided into compartments. Solving the model for large instances is computationally expensive. ... 
A new type of Taylor series expansion
(SpringerOpen, 20180515)We present a variant of the classical integration by parts to introduce a new type of Taylor series expansion and to present some closed forms for integrals involving Jacobi and Laguerre polynomials, which cannot be directly ...
