Voids and superstructures: Correlations and induced large-scale velocity flows
(Wiley Blackwell Publishing, Inc, 2017-09)
The expanding complex pattern of filaments, walls and voids build the evolving cosmic web with material flowing from underdense on to high density regions. Here, we explore the dynamical behaviour of voids and galaxies in ...
An Analysis of Distributed Programming Models and Frameworks for Large-scale Graph Processing
(Taylor & Francis, 2020-04-30)
In recent years, processing and analysing large graphs has become a major need in many research areas. Distributed graph processing programming models and frameworks arised as a natural solution to process linked data of ...
Spatial correlations of extended cosmological structures
(Wiley Blackwell Publishing, Inc, 2020-05)
Studies of large-scale structures in the Universe, such as superstructures or cosmic voids, have been widely used to characterize the properties of the cosmic web through statistical analyses. On the other hand, the two-point ...
Effects of large and spread explosive ooads
(Multi Science Publishing, 2010-09)
This paper presents experimental data and numerical analysis of the effects of detonating explosive charges ranging from 1000 to 26288 kg laid out on the ground. The charges consist of different ordnances widespread in ...
Large time behavior for a nonlocal diffusion equation with absorption and bounded initial data: The subcritical case
(IOS Press, 2015-10)
In this paper we continue our study of the large time behavior of the bounded solution to the nonlocal diffusion equation with absorption ut=Lu−upin RN×(0,∞),u(x,0)=u0(x)in RN, where p>1, u0⩾0 and bounded and Lu(x,t)=∫J( ...
Independent component analysis of MODIS-NDVI data in a large South American wetland
(Taylor & Francis, 2012-09)
Monthly images of Normalized Difference Vegetation Index (NDVI) from the moderate resolution imaging spectroradiometer (MODIS) are used to characterize the spatio-temporal variability of vegetation in a large South American ...
Brightest group galaxies and the large-scale environment
(Wiley Blackwell Publishing, Inc, 2015-01)
We study the dependence of the properties of group galaxies on the surrounding large-scale environment, using Sloan Digital Sky Survey-seventh data release data. Galaxies are ranked according to their luminosity within ...
An assemblage of large-sized insect traces in paleosols from the middle miocene of northern Patagonia related to the climatic optimum
(Pergamon-Elsevier Science Ltd, 2021-08)
A new assemblage of large insect trace fossils is recognized in paleosols of the middle Miocene pyroclastic deposits from extra-Andean north Patagonia. This assemblage includes Racemusichnus jacobacciensis igen. isp. nov., ...
Participatory networks for large-scale monitoring of large carnivores: Pumas and jaguars of the Upper Paraná atlantic forest
(Cambridge University Press, 2011-10)
Most large carnivores are secretive and threatened, and these characteristics pose problems for research on, and monitoring of, these species across extensive areas. Participatory monitoring, however, can be a useful tool ...
Axiomatizing hybrid xpath with data
(Technische Universität Braunschweig, 2021-07)
In this paper we introduce sound and strongly complete axiomatizations for XPath with data constraints extended with hybrid operators. First, we present HXPath=, a multi-modal version of XPath with data, extended with ...
