(Institute of Physics Publishing, 2018)The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope in 2016 and 2017 are given, totaling 2483 measurements of 1570 resolved pairs and 609 non-resolutions. We describe ...
-
(Elsevier Ltd, 2018)Text search engines are a fundamental tool nowadays. Their efficiency relies on a popular and simple data structure: inverted indexes. They store an inverted list per term of the vocabulary. The inverted list of a given ...
-
(CEUR-WS, 2018)The use of the join operator in metric spaces leads to what is known as a similarity join, where objects of two datasets are paired if they are somehow similar. We propose an heuristic that solves the 1-NN selfsimilarity ...
-
(Elsevier B.V., 2018)The study of Late Cretaceous-earliest Paleogene series in the Chilean Andes at ~35°S provides new constraints on the coeval evolution of the area and the Southern Central Andes. These correspond to the continental series ...
-
(Springer Verlag, 2018)We describe and analyze the first adaptive algorithm for merging k convex hulls in the plane. This merging algorithm in turn yields a synergistic algorithm to compute the convex hull of a set of planar points, taking ...
-
(Elsevier B.V., 2018)Three EuIII macrocyclic complexes [EuLnH2(NO3)3](H2O)x based on the ligands derived from 2-hydroxy-5-methyl-1,3-benzenedicarbaldehyde and three different amines: o-phenylenediamine, Eu-OPDA; ethylenediamine, Eu-EDA; and ...

Existence and nonexistence of positive solutions to some fully nonlinear equation in one dimension (Academic Press Inc., 2018)In this paper, we consider the existence (and nonexistence) of solutions to −Mλ,Λ ±(u″)+V(x)u=f(u)inR where Mλ,Λ + and Mλ,Λ − denote the Pucci operators with 0<λ≤Λ<∞ V(x) is a bounded function, f(s) is a continuous ...
-
(Elsevier Ltd, 2018)In this paper, the effect of soil structure interaction and base isolation on the dynamic characteristics of an instrumented bridge is examined using transfer functions and measured motions in the frequency domain. A three ...
-
(Association for Computing Machinery, Inc, 2018)Network pricing games provide a framework for modeling real-world se ings with two types of strategic agents: owners (operators) of the network and users of the network. Owners of the network post a price for usage of ...
-
(Elsevier B.V., 2018)Our understanding of the response of the Antarctic ice sheet to climate and ocean changes requires the improvement of current ice-atmosphere-ocean models and the accurate determination of boundary conditions such as ice ...

A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA (Oxford University Press, 2018)While detecting low mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary systems. Here we report new ALMA observations of the ...
-
(Springer Netherlands, 2018)This paper presents the results of a systematic review of the empirical literature, reported in research journals, on Mathematics Learner Identity (MLI). In the mathematics education research field, arguments have been ...
-
(American Physical Society, 2018)The search of new means of generating and controlling topological states of matter is at the front of many joint efforts, including band-gap engineering by doping and light-induced topological states. Most of our ...
-
(IEEE Computer Society, 2018)Live Programming environments allow programmers to get feedback instantly while changing software. Liveness is gaining attention among industrial and open-source communities; several IDEs offer high degrees of liveness. ...
-
(Elsevier Ltd, 2018)The capacity of structural systems subjected to shear loads commonly distinguished by discontinuities such as point loads or supports, or abrupt changes of cross section, where complex fields of stresses and strains are ...
-
(Elsevier Ltd, 2018)We derive the optimal concession contract for an airport where the concessionaire’s effort impacts either non-aeronautical revenue (shops, restaurants, parking lots and hotels) or aeronautical revenues (passenger and ...
-
(Oxford University Press, 2018)In large optical surveys at high redshifts (z > 2), the C IV λ1549 broad emission line is the most practical alternative to estimate the mass (MBH) of active supermassive black holes. However, mass determinations obtained ...

Cognitive impact evaluation of multimodal interfaces for blind people: Towards a systematic review (Springer Verlag, 2018)Visual disability has a major impact on people’s quality of life. Although there are many technologies to assist people who are blind, most of them do not necessarily guarantee the effectiveness of the intended use. Then, ...
-
(Institute of Physics Publishing, 2018)ZnS thin films grown by the chemical bath deposition method have been under intense investigation due to their applications in solar cells. In this work, the early growth stages of ZnS thin films deposited by means of a ...
-
(Institute of Physics Publishing, 2018)We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0farcs3 resolution of EX Lup, the prototype of the EXor class of outbursting pre-main-sequence stars. The circumstellar disk of EX Lup is ...
