(1999)We consider a Brownian motion in a Benedicks domain with absorption at the boundary. We show ratio limit theorems for the associated heat kernel. When the hole is compact, therefore the Martin boundary is two dimensional; ...

Re-Os isotope constraints on subcontinental lithospheric mantle evolution of southern South America (ELSEVIER SCIENCE BV, 2008-04-15)We present Re-Os isotopic data for widely dispersed mantle xenoliths carried to the surface of southern South America (36 degrees-52 degrees S) by Eocene to recent alkaline magmatism. Our hypothesis is that the lithospheric ...
-
(2009)Compression of inverted lists with methods that support fast intersection operations is an active research topic. Most compression schemes rely on encoding differences between consecutive positions with techniques that ...
-
(2007)Reaction cross sections for proton-nucleus elastic scattering are investigated within a nonrelativistic microscopic approach for the nucleon-nucleus optical model potential. Applications were made for nucleon energy ...
-
(American Geophysical Union., 2020)In active volcanic arcs such as the Andean volcanic mountain belt, magmatically sourced fluids are channeled through the brittle crust by faults and fracture networks. In the Andes, volcanoes, geothermal springs, and ...
-
(MDPI, 2017)Underwater sensor networks represent an important and promising field of research due to the large diversity of underwater ubiquitous applications that can be supported by these networks, e.g., systems that deliver tsunami ...
-
(Wiley, 2014)Navigating is a complex cognitive task that places high demands on spatial abilities, particularly in the absence of sight. Significant advances have been made in identifying the neural correlates associated with various ...
-
(Elsevier Ltd, 2018)We develop accident prediction models for a stretch of the urban expressway Autopista Central in Santiago, Chile, using disaggregate data captured by free-flow toll gates with Automatic Vehicle Identification (AVI) which, ...
-
(Springer, 2015)Early earthquake warning is a rapidly developing capability that has significant ramifications for many fields, including astronomical observatories. In this work, we describe the susceptibility of astronomical facilities ...
-
(Frontiers Media, 2020)In the absence of a consensus protocol to slow down the spread of SARS-CoV-2, policymakers need real-time indicators to support decisions in public health matters. The Effective Reproduction Number (Rt) represents the ...
-
(Springer-Verlag, 2014)During the unit event of material iteraction in grinding three phenomena are involved, namely: rubbing, ploughing and cutting. Where ploughing and rubbing essentially mean the energy is being applied less efficiently ...
-
(2012-12-17)In this article a robust and real-time hand gesture detection and recognition system for dynamic environments is proposed. The system is based on the use of boosted classifiers for the detection of hands and the ...
-
(2007)Real-time face and iris detection on video sequences is important in diverse applications such as, study of the eye function, drowsiness detection, virtual keyboard interfaces, face recognition, and multimedia retrieval. ...
-
(NATL ACAD SCI, 2006)The aim of the real-time mass transport vehicle routing problem (MTVRP) is to find a solution to route n vehicles in real time to pick up and deliver m passengers. This problem is described in the context of flexible ...
-
Real-Time Structural Damage Assessment Using Artificial Neural Networks and Antiresonant Frequencies (Hindawi, 2014)The main problem in damage assessment is the determination of how to ascertain the presence, location, and severity of structural damage given the structure’s dynamic characteristics. The most successful applications of ...
-
(Elsevier, 2016)This paper proposes a new tool for the evaluation of face analysis systems under dynamic experimental conditions. The tool primarily consists of a virtual environment where a virtual agent (e.g., a simulated robot) carries ...
-
(CAMBRIDGE UNIV PRESS, 2006-10)In this paper we show that, for every Choquet simplex K and for every d > 1, there exists a Z(d)-Toeplitz system whose set of invariant probability measures is affine homeomorphic to K. Then, we conclude that K may be ...
-
(Nature, 2021)In this study, (1 − x) BFO-xCFO (CFO, x = 0.00, 0.05, 0.10 and 0.30) ceramics were synthesized by a solid-state reaction method; their compositions were driven by structural, microstructural, vibrational, electrical, ...
-
(SPRINGER-VERLAG BERLIN, 2006)Time management is a key feature needed in any query language for web and semistructured data. However, only recently this has been addressed by the Semantic Web community, through the study of temporal extensions to RDF ...
-
(Elsevier, 2017)Raman spectroscopy has proven to be an effective tool to confirm the presence and abundance of CO2 in fluid and melt inclusions. The Ramanmethod for quantifying CO2 abundance is based on the observation that the ...
