(De Gruyter, 2015)Linear and projective boundaries of Cayley graphs were introduced in [6] as quasi-isometry invariant boundaries of finitely generated groups. They consist of forward orbits g1 D ¹gi W i 2 Nº, or orbits g 1 D ¹gi W i 2 ...
-
(Springer, 2013)This paper is devoted to the study of the symmetric cone linear complementarity problem (SCLCP). Specifically, our aim is to characterize the class of linear transformations for which the SCLCP has always a nonempty and ...
-
(Springer, 2017)We propose a method for simulating linear elastic crack growth through an isogeometric boundary element method directly from a CAD model and without any mesh generation. To capture the stress singularity around the crack ...
-
(Wiley, 2017)The strain smoothing technique over higher order elements and arbitrary polytopes yields less accurate solutions than other techniques such as the conventional polygonal finite element method. In this work, we propose a ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)In this paper we establish that the set of Lipschitz functions f : U → R (U a nonempty open subset of ` 1 d ) with maximal Clarke subdifferential contains a linear subspace of uncountable dimension (in particular, an ...
-
(Elsevier Science BV., 2016-08)Linearity and contiguity are two parameters devoted to graph encoding. Linearity is a generalization of contiguity in the sense that every encoding achieving contiguity k induces an encoding achieving linearity k, both ...
-
(Wiley, 2020)The line generated by two distinct points, x and y, in a finite metric space M=(V,d), is the set of points given by {z is an element of V:d(x,y)=|d(x,z)+d(z,y)|ord(x,y)=|d(x,z)-d(z,y)|}. It is denoted by xy over bar M. A ...
-
(IOS Press, 2015)Traditional approaches for querying the Web of Data often involve centralised warehouses that replicate remote data. Conversely, Linked Data principles allow for answering queries live over the Web by dereferencing URIs ...
-
(Universidad de Chile, 2021)La Web es una enorme plataforma de información, que ha crecido a pasos agigantados durante este milenio. Pero esta información es legible en la medida de que quién la lea sea un humano; las máquinas encargadas de transportar, ...
-
(Springer International Publishing, 2019)© 2018, Swiss School of Public Health (SSPH+).Objectives: To describe and compare the profile of female sex workers (FSWs) that access or do not access sexual health checkups (SHC). The research question was what are the ...
-
(2013)Censuses are one of the most relevant types of statistical data, allowing analyses of the population in terms of demography, economy, sociology, and culture. For finegrained analysis, census agencies publish census microdata ...
-
(IOP Publishing, 2016-06-10)In a survey of 65 galaxies, Gao & Solomon found a tight linear relation between the infrared luminosity (L-IR, a proxy for the star formation rate) and the HCN(1-0) luminosity (L-HCN). Wu et al. found that this relation ...
-
(EDP Sciences, 2022)Context. Stellar feedback is one of the fundamental factors regulating the evolution of galaxies. However, we still do not have access to strong observational constraints on the relative importance of the di fferent feedback ...
-
(2012-06-20)Comparing the ejecta velocities at maximum brightness and narrow circumstellar/interstellar Na D absorption line profiles of a sample of 23 Type Ia supernovae (SNe Ia), we determine that the properties of SN Ia progenitor ...
-
(Oxford, 2021)We present the discovery and characterization of an eclipsing binary identified by the Next Generation Transit Survey in the similar to 115-Myr-old Blanco 1 open cluster. NGTS J0002-29 comprises three M dwarfs: a short-period ...
-
(Springer, 2020)We provide some necessary and sufficient conditions for a proper lower semicontinuous convex function, defined on a real Banach space, to be locally or globally Lipschitz continuous. Our criteria rely on the existence of ...
-
(Elsevier, 2015)The second-strongest earthquake recorded in Chile's history, only exceeded by the 1960 Valdivia earthquake of Magnitude 9.5, occurred on February 27, 2010. This mega thrust-faulting type earthquake of Magnitude 8.8 struck ...
-
(Elsevier, 2017)In the Mo-Cu system, Mo has very low solubility in liquid Cu. To reach high densities after liquid phase sintering it is required the solution-reprecipitation step, which induces shape change. One technique that allows to ...
-
(NATURE PUBLISHING GROUP, 2008-03)The theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions between them. In contrast, ...
