(Society for Industrial and Applied Mathematics Publications, 2019)We characterize the subdifferential of the supremum function of finitely and infinitely indexed families of convex functions. The main contribution of this paper consists of providing formulas for such a subdifferential ...
-
(Elsevier Ltd, 2019)Aggregation operators consist of mathematical functions that enable the combining and processing of different types of information. The aim of this work is to present the main contributions in this field by a bibliometric ...
-
(Cambridge University Press, 2019)The study of the stone sculpture production process is subject to the preservation and visibility of tool traces and surface finishes. In this article it is proposed that the parameters developed in conservation for the ...
-
(NLM (Medline), 2019)Hypoxia, a common condition of the tumor microenvironment, induces changes in the proteome of cancer cells, mainly via HIF-1, a transcription factor conformed by a constitutively expressed β-subunit and an oxygen-regulated ...
-
(Springer Verlag, 2019)We consider the Cauchy problem for the energy critical heat equation {ut=Δu+|u|4n−2uinRn×(0,T)u(⋅,0)=u0inRn in dimension n = 5. More precisely we find that for given points q 1 ,q 2 ,..,q k and any sufficiently small T ...
-
(AIDEP, 2019)Early identification of children who may have a mental health problem is essential to implement preventive and treatment actions. In order to do this, it is necessary to have valid instruments adapted to the characteristics ...
-
(MDPI AG, 2019)Nitric oxide-releasing aspirins (NO-aspirins) are aspirin derivatives that are safer than the parent drug in the gastrointestinal context and have shown superior cytotoxic effects in several cancer models. Despite the ...

(Frontiers Media S.A., 2019)Copyright © 2019 Robledo, Gutiérrez, Barría, Lhorente, Houston and Yáñez.Sea lice (Caligus rogercresseyi) are ectoparasitic copepods which have a large negative economic and welfare impact in Atlantic salmon (Salmo salar) ...
-
(Magnolia Press, 2019)A new fossil cycad species, Sueria laxinervis, is described from the Upper Cretaceous (Maastrichtian) Quiriquina Formation in Cocholgüe, Bíobío Region, Chile. The generic assignment is supported by the taeniopterid-type ...
-
(Springer Verlag, 2019)Extreme environments are a unique source of microorganisms encoding metabolic capacities that remain largely unexplored. In this work, we isolated two Antarctic bacterial strains able to produce poly(3-hydroxyalkanoates) ...
-
(MDPI AG, 2019)This paper proposes a low-complexity small signal model for a 3-leg converter connected to a balanced three-phase, three-wire weak grid and synchronised to this grid using a PLL implemented in a synchronous rotating d-q ...
-
(Frontiers Media S.A., 2019)Copyright © 2019 Flores-Ríos, Moya-Beltrán, Pareja-Barrueto, Arenas-Salinas, Valenzuela, Orellana and Quatrini.The dispersal of mobile genetic elements and their gene cargo relies on type IV secretion systems (T4SS). In ...
-
(Royal Society of Chemistry, 2019)The mechanism of the SNAr reactions between 1-halo-2,4-dinitrobenzenes and amines was revisited by means of DFT calculations. Remarkably and contrary to the traditional text-book perspective, the dehalogenation of ...
-
(Wiley-Blackwell, 2019)Background: Encapsulation of Porphyromonas gingivalis has been demonstrated as responsible of several host immunological changes, which have been associated with the pathogenesis of periodontitis. Using a murine model of ...
-
(American Chemical Society, 2019)Pr (1-12% wt) promoted Ni-Mg-Al mixed oxides were synthesized by the microwave-assisted self-combustion method. The promoting role of Pr on the physical and chemical properties and the catalytic performance in dry reforming ...
-
(Palgrave Macmillan Ltd., 2019)Using a panel data set for international corporate bonds and capital account restrictions in advanced and emerging economies, we show that restrictions on capital inflows produce a substantial and economically meaningful ...
-
(Elsevier Ltd, 2019)This paper aims at better understanding passenger valuation of subway crowding in New York City. To this end, we conducted a stated preference survey with a discrete choice experiment where New Yorkers chose an alternative ...
-
(Blackwell Publishing, 2019)Background: This study aimed to determine the effect of the consumption of a probiotic on the clinical characteristics of Candida-associated denture stomatitis (DS) and to determine the impact of a protocol of self-care ...
-
(Elsevier Ltd, 2019)Bilateral simultaneous radial palsy is uncommon, and the few cases reported in the literature are due to compressive injuries, such as in the use of axillary crutch or birthing bar during labor. We present a patient who ...
-
(American Physical Society, 2019)In holographic inflation, the 4D cosmological dynamics is postulated to be dual to the renormalization group flow of a 3D Euclidean conformal field theory with marginally relevant operators. The scalar potential of the 4D ...
