(Institute of Physics Publishing, 2018)We present our statistical analysis of the connection between active galactic nuclei (AGN) variability and physical properties of the central supermassive black hole (SMBH). We constructed optical light curves using data ...
-
(Oxford University Press, 2020)In this paper, we present the analysis of new radio and optical observations of the narrow-line Seyfert 1 galaxy Mrk 783. 1.6 GHz observations performed with the e-MERLIN interferometer confirm the presence of the diffuse ...
-
(Wiley-Hindawi, 2018)This paper presents a multi-time channel prediction system based on backpropagation (BP) neural network with multi-hidden layers, which can predict channel information effectively and benefit for massive MIMO performance, ...
-
(EDP Sciences, 2016)The nearby red dwarf binary GJ65 AB (UV + BL Ceti, M5.5Ve + M6Ve) is a cornerstone system to probe the physics of very low-mass stars. The radii of the two stars are currently known only from indirect photometric estimates, ...
-
(2011)The Red MSX Source (RMS) survey has identified a large sample of massive young stellar objects and ultra compact HII regions from a sample of ∼2000 MSX and Two Micron All Sky Survey (2MASS) colour selected sources. Using ...
-
(Elsevier, 2020)Reduction of Fe-phases in a slag from the copper smelting process is studied for its use as a catalyst in methanation of carbon oxide (CO). This material contains 36.4 wt% Fe and the main Fe-phases in its fresh and reduced ...
-
(Cambridge University Press, 2016)The relation between the star-formation Rate and stellar mass (M-star) of galaxies represents a fundamental constraint on galaxy formation, and has been studied extensively both in observations and cosmological hydrodynamic ...
-
(MDPI, 2021)Porphyry Cu-Mo deposits are among the world’s largest source of Cu, Mo, and Re, and are also an important source of other trace elements, such as Au and Ag. Despite the fact that chalcopyrite, bornite, and pyrite are the ...
-
(2016)The Magellanic Clouds provide the only laboratory to study the effects of metallicity and galaxy mass on molecular gas and star formation at high (similar to 20 pc) resolution. We use the dust emission from HERITAGE Herschel ...
-
(Elsevier, 2020)The Central Andes between 18 degrees S and 36 degrees S latitude strike north-south for 2000 km along the Chilean subduction margin, cross several climate zones from hyperarid to humid and exhibit mean elevations in excess ...
-
(Elsevier, 2018)Water and energy are essential requirements for mineral processing plants, and they can be either scarce or expensive. In the present paper, the implications of a remote water source location (typically the seashore) are ...
-
(IOP Publishing Ltd., 2017)We present the first determination of the galaxy luminosity function (LF) at z ∼4, 5, 6, and 7, in the rest-frame optical at l ~ rest 900 nm (z′ band). The rest-frame optical light traces the content in low-mass evolved ...
-
(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 Inc., 2019)ROS, the Robot Operating System, offers a core set of software for operating robots that can be extended by creating or using existing packages, making it possible to write robotic software that can be reused on different ...
-
(Elsevier, 2017)In this work, we have compared the carbohydrate content and the enzymatic saccharification of the brown algae Macrocystis pyrifera from Chile and Saccharina latissima from Norway. M. pyrifera contained 40% mannitol, 31% ...
-
(MDPI, 2021)Renewable generation technologies are rapidly penetrating electrical power systems, which challenge frequency stability, especially in power systems with low inertia. To prevent future instabilities, this issue should ...
-
(Nature, 2021)Quaternary deformation in the northern Chile forearc is controlled by trench parallel shortening along reactivated Mesozoic faults. Dextral strikes-slip is expressed in NW-SE striking faults of the Atacama Fault System, ...
-
(Academic Press Inc., 2019)Nitric oxide (NO) is the main vasodilator agent that drives the rapid decrease of pulmonary vascular resistance for the respiratory onset during the fetal to neonatal transition. Nevertheless, the enhanced NO generation ...
-
(Seismological Soc Amer, 2021)The 22 May 1960 Mw 9.5 Valdivia megathrust earthquake, with a rupture length close to 1000 km in the central–south Chile, is the largest recorded earthquake in the modern times. The city of Valdivia is located about 300 ...
-
(MDPI, 2021)The mining industry is facing emerging challenges as a result of the increase in energy consumption and environmental demands. These facts have promoted the use of renewable energy sources, such as wind, geothermal and, ...
