Holstein-Friesian milk performance in organic farming in North Spain: Comparison with other systems and breeds
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2017)Organic systems are highly dependent on the environment and require animals well adapted to local conditions. In Spain, organic dairy farmers are not satisfied with the productive performance of their herds and ask for ... -
idmTPreg: Regression Model for Progressive Illness Death Data
(The R Foundation, 2018)This paper describes the implementation of a flexible method in R for fitting a regression model to possibly non-Markov progressive illness-death data. The idmTPreg package offers the user the opportunity to estimate ... -
Implicit Fractional Differential Equations via the Liouville–Caputo Derivative
(MDPI, 2015)We study an initial value problem for an implicit fractional differential equation with the Liouville–Caputo fractional derivative. By using fixed point theory and an approximation method, we obtain some existence and ... -
Influence of socioeconomic status on community-acquired pneumonia outcomes in elderly patients requiring hospitalization: a multicenter observational study
(BioMed Central, 2010)Background The associations between socioeconomic status and community-acquired pneumonia outcomes in adults have been studied although studies did not always document a relationship. The aim of this multicenter ... -
Influence of storage conditions on the sensory and physicochemical characteristics of Galician Kennebec potatoes (Solanum tuberosum L.)
(Taylor & Francis, 2012)In this study, we compared conventional storage of Kennebec potatoes in a ventilated room at ambient temperature with storage at controlled temperatures of 10, 7 and (initially) 4°C as regards the evolution of colour, ... -
Initial Value Problem For Nonlinear Fractional Differential Equations With ψ-Caputo Derivative Via Monotone Iterative Technique
(MDPI, 2020)In this article, we discuss the existence and uniqueness of extremal solutions for nonlinear initial value problems of fractional differential equations involving the ψ -Caputo derivative. Moreover, some uniqueness results ... -
Interior Regularity Estimates for a Degenerate Elliptic Equation with Mixed Boundary Conditions
(MDPI, 2018)The Marchaud fractional derivative can be obtained as a Dirichlet-to–Neumann map via an extension problem to the upper half space. In this paper we prove interior Schauder regularity estimates for a degenerate elliptic ... -
Is It Possible to Construct a Fractional Derivative Such That the Index Law Holds?
(Natural Sciences Publishing Corp., 2018-01-01)The aim of this note is to make a brief consideration about the Index Law in fractional differentiation. We are not interested in any particular definition of fractional derivative, and that is why we will not introduce ... -
La matemática, la ciencia que ayuda a combatir incendios
(Colexio Oficial de Enxeñeiros Técnicos Industriais de A Coruña (Coeticor), 2018)El proyecto LUMES y el ENJAMBRE contribuirán a desarrollar tecnologías para optimizar los esfuerzos dedicados a la extinción de fuegos y permitirán reducir la superficie afectada, así como aumentar la seguridad de las ... -
Las elecciones generales de 2008 y el juego del parlamento
(Federación Española de Profesores de Matemáticas, 2010)En este artículo analizamos el resultado de las elecciones generales desde un punto de vista Teórico de Juegos. Para cuantificar el poder que cada partido tiene en el nuevo Parlamento introducimos tres conceptos, los ... -
A Lipschitz condition along a transversal foliation implies local uniqueness for ODEs
(University of Szeged, 2018)We prove the following result: if a continuous vector field F is Lipschitz when restricted to the hypersurfaces determined by a suitable foliation and a transversal condition is satisfied at the initial condition, then F ... -
Lower and upper solutions for even order boundary value problems
(MPDI, 2019)In this paper, we prove the existence of solutions of nonlinear boundary value problems of arbitrary even order using the lower and upper solutions method. In particular, we point out the fact that the existence of a ... -
Lyapunov-type inequalities for a higher order fractional differential equation with fractional integral boundary conditions
(Bolyai Institute, University of SzegedHungarian Academy of Sciences, 2017)New Lyapunov-type inequalities are derived for the fractional boundary value problem Daa u(t) + q(t)u(t) = 0, a <t <b, u(a) = u0(a) = … = u(n-2)(a) = 0, u(b) = Iaa (hu)(b), where n E IN, n > 2, n - 1 < <n, Daa ... -

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 data-splitting ... -
