(American Physical Society, 2018)We show that the shape of the inflationary landscape potential may be constrained by analyzing cosmological data. The quantum fluctuations of fields orthogonal to the inflationary trajectory may have probed the structure ...
-
(Institute of Mathematical Statistics, 2018)We study the long-time behavior of the dynamics of interacting planar Brownian particles, confined by an external field and subject to a singular pair repulsion. The invariant law is an exchangeable Boltzmann – Gibbs ...
-
(MDPI AG, 2018)This work demonstrates a formal connection between density estimation with a data-rate constraint and the joint objective of fixed-rate universal lossy source coding and model identification introduced by Raginsky in ...
-
(Springer Verlag, 2017)In this work a system for recognizing grasp points in RGB-D images is proposed. This system is intended to be used by a domestic robot when deploying clothes lying at a random position on a table. By taking into ...
-
(MDPI AG, 2018)The introduction of non-conventional energy sources (NCES) to industrial processes is a viable alternative to reducing the energy consumed from the grid. However, a robust coordination of the local energy resources with ...
-
(Springer Verlag, 2018)Caching in the context of expressive query languages such as SPARQL is complicated by the difficulty of detecting equivalent queries: deciding if two conjunctive queries are equivalent is NP-complete, where adding further ...
-
(Springer Verlag, 2018)Faceted browsing has become a popular paradigm for user interfaces on the Web and has also been investigated in the context of RDF graphs. However, current faceted browsers for RDF graphs encounter performance issues when ...
-
(MDPI AG, 2018)A general framework for inference in dynamical systems is described, based on the language of Bayesian probability theory and making use of the maximum entropy principle. Taking the concept of a path as fundamental, the ...
-
(EDP Sciences, 2018)Context. The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and several spiral arms. A low-mass ...
-
(Springer Verlag, 2018)The main goal of this paper is to analyze the general problem of using Convolutional Neural Networks (CNNs) in robots with limited computational capabilities, and to propose general design guidelines for their use. In ...
-
(Springer Verlag, 2018)This work introduces a model of the crew scheduling problem for the operation of trains in the mining industry in the North of Chile. The model possesses particular features due to specific regulations with which train ...
-
(Springer Verlag, 2018)We study the thermodynamics of a quantum system interacting with different baths in the repeated interaction framework. In an appropriate limit, the evolution takes the Lindblad form and the corresponding thermodynamic ...
-
(Springer Verlag, 2018)There are efficient dynamic programming solutions to the computation of the Edit Distance from S ∈in [1..σ]n to T ∈in [1..σ]m, for many natural subsets of edit operations, typically in time within O(nm) in the worst-case ...
-
(Institute of Physics Publishing, 2018)We present Atacama Large Millimeter/submillimeter Array observations of multiple protostar systems in the Perseus molecular cloud, previously detected by the Karl G. Jansky Very Large Array. We observe 17 close (<600 au ...
-
(CEUR-WS, 2018)An important aspect of exploratory search over graph data is to understand what paths connect a given pair of nodes. Since the resulting paths can be manifold, various works propose ranking paths likely to be of interest ...
-
(Springer Verlag, 2018)The discrete Fréchet distance is a measure of similarity between point sequences which permits to abstract differences of resolution between the two curves, approximating the original Fréchet distance between curves. ...
-
(CEUR-WS, 2018)All rights reserved. This work presents the main observations obtained from the study of several path loss models in the context of vehicular communications that employ frequency bands of TV White Spaces. We have simulated ...
-
(SPIE, 2018)We present the concept and experimental development of a low-cost near-infrared heterodyne interferometer prototype based on commercial 1.55 μm fiber components. As the most crucial component of it we characterized a novel ...
-
(Blackwell Publishing Ltd, 2018)New thermochronometric data provide evidence for an along-strike diachronous building of the Andes in north-central Chile (28.5–32°S). Geochronological (U-Pb zircon) and thermochronological (apatite fission track and ...
-
(Springer New York LLC, 2018)Recent interest on studying possible violations of the Equivalence Principle has led to the development of space satellite missions testing it for bodies moving on circular orbits around Earth. This experiment establishes ...
