-
(2007)Boundary value problems for systems of ordinary differential equations are studied. These systems involve asymptotically homogeneous operators. Leray-Schauder indices are calculated for these operators and the concept of ...
-
(EDP Sciences, 2016)Context. The B-W method is used to determine the distance of Cepheids and consists in combining the angular size variations of the star, as derived from infrared surface-brightness relations or interferometry, with its ...
-
(Universidad de Concepcion, 2019)The supply of fresh, high-quality and easily accessible vegetables is essential to improve the diet in Chile. The central zone is the main production area of the country. The objective of this research was to characterize ...
-
(Universidad de la Frontera, 2019)The VEGF levels and its binding to its receptors are key stages in the regulation of angiogenesis. Acetylsalicylic acid (ASA), widely used in post-myocardial infarction treatment, has been shown to have an anti-angiogenic ...
-
(Institute of Electrical and Electronics Engineers Inc., 2019)The lack of available spectrum for wireless communications is a threat to the successful deployment of applications designed for intelligent transportation systems (ITSs). The ITS services should be available to a high ...
-
(IOP PUBLISHING LTD, 2004-10-01)We present observations of the Vela X region at 31 GHz using the Cosmic Background Imager ( CBI). We find a strong compact radio source (5.'9 x 4.'1, FWHM) about the Vela pulsar, which we associate with the Vela pulsar ...
-
(1994-07-01)We present H92alpha radio recombination line and radio continuum observations toward three cometary-like H II regions, G13.87 + 0.28, G32.80 + 0.19B, and G61.48 + 0.09B1, with an angular resolution of approximately 2''. ...

Verifying the high-order consistency of training images with data for multiple-point geostatistics (Elsevier, 2014)Parameter inference is a key aspect of spatial modeling. A major appeal of variograms is that they allow inferring the spatial structure solely based on conditioning data. This is very convenient when the modeler does not ...
-
(SPRINGER-VERLAG BERLIN, 2006)Aspect-Oriented Programming (AOP) promotes better separation of concerns in software systems by introducing aspects for the modular implementation of crosscutting concerns. As a result, modularity and adaptability of ...
-
(SPRINGER-VERLAG BERLIN, 2006)In the last few years there has been an increasing interest in studying ontology evolution and versioning for the World Wide Web, in particular, applied to OWL. However, little attention has been given to the problem of ...
-
(American Physical Society, 2020)The vertex model is widely used to describe the dynamics of epithelial tissues, because of its simplicity and versatility and the direct inclusion of biophysical parameters. Here, it is shown that quite generally, when ...
-
(2007-07)Let G be a graph with maximum degree d ≥ 3 and ω(G) ≤ d, where ω(G) is the clique number of the graph G. Let p1 and p2 be two positive integers such that d = p1 + p2. In this work, we prove that G has a vertex ...
-
(Taylor & Francis, 2017)Located at the intersection of the triple junction between the Nazca, South American, and Antarctic plates, the Chilean territory is subject to active lithospheric deformations and seismicity. Taking the difference between ...
-
(Elsevier, 2018)The design process of a photoconductive antenna (PCA), which emits efficiently in the electromagnetic terahertz range, demands some considerations that are discussed through this work. In this work, several essential ...
-
(2007)We present radio-continuum observations at 7 mm made using the Very Large Array toward three massive star-forming regions thought to be in very early stages of evolution, selected from the 2002 sample of Sridharan et al. ...
-
Very Large Telescope observations of Gomez's Hamburger: Insights into a young protoplanet candidate (ESO, 2015)Planets are thought to form in the gas and dust disks around young stars. In particular, it has been proposed that giant planets can form through the gravitational instability of massive extended disks around intermediate-mass ...
-
(Elsevier, 2016)The Upper Cretaceous basic volcanic succession in Hannah Point, Livingston Island, Antarctica, presents a widespread occurrence of very low-grade secondary minerals. They occur filling amygdules, veins and veinlets, and ...
-
(Elsevier, 2011)This paper deals with the control of discrete-time dynamical, monotone both in the state and in the control, in the presence of state and control monotone constraints. A state x is said to belong to the viability kernel ...
-
(Elsevier Ltd, 2019)In this study, the vibration behaviours of functionally graded microplates with cracks are investigated by means of a simple yet rigorous version of Mindlin's generialised continuum and the extended isogeometric analysis ...
-
Vibration-Based Damage Detection in Historical Adobe Structures: Laboratory and Field Applications (Taylor and Francis Inc., 2019)© 2019, © 2019 Taylor & Francis.Structural Health Monitoring (SHM) has demonstrated to be a fundamental tool for detecting damage in early stages in existent civil engineering structures. This paper explores the accuracy ...
