(American Chemical Society, 2017)The electronic structure of self-assembled monolayers (SAMs) formed by thiols of different lengths and dithiol molecules bound to Au(111) has been characterized. Inverse photoemission spectroscopy (IPES) and density ...
-
(Elsevier, 2020)Water contaminated by arsenic is a tremendous risk for health and environment due to its toxic and carcinogenic nature thus asking for more advanced and efficient removal strategies. Therefore, the aim of this study is to ...
-
(Elsevier, 2020)4H-silicon carbides deposited by diamond films have wide applications in many fields such as semiconductor heterojunction, heat sink and mechanical sealing. Nucleation plays a critical role in the deposition of the diamond ...
-
(Elsevier B.V., 2019)Random interactions among pedestrians, usually produced by psychological effects (e.g. anxiety), can produce collective nontrivial phenomena in their flow dynamics. Here, we improve our understanding on these phenomena by ...
-
(IOP Publishing, 2020)We report on a multiband variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 19. The study uses, among others, data from GLAST-AGILE Support ...
-
(Frontiers Media, 2020)The oxidation state of the Earth's mantle and its partial melting products exert a key control on the behavior and distribution of sulfur and chalcophile and siderophile elements between the mantle and crust, underpinning ...
-
(Elsevier, 2017)The Andean IOCG clan in the Coastal Cordillera of northern Chile, comprises the iron oxide-Cu-Au sensu stricto, the iron oxide-apatite (IOA), and the stratabound Cu(-Ag) deposits, also known as Manto-type Cu(-Ag) ...
-
(Wiley-Blackwell, 2016)The Salar de Atacama Basin holds important information regarding the tectonic activity, sedimentary environments and their variations in northern Chile during Cretaceous times. About 4000m of high-resolution stratigraphic ...
-
(EDP Sciences, 2016)Context. Stellar populations are the building blocks of galaxies, including the Milky Way. The majority, if not all, extragalactic studies are entangled with the use of stellar population models given the unresolved nature ...
-
(Springer, 2013)The results of investigation of molecular cloud LDN133 and the unstable objects HHL59, HHL59A, HHL59B and HHL59C connected with it are given. The IR nebula and IR star cluster are also connected with LDN133. It is shown ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-10)In this work the unsteady non-Newtonian blood flow and mass transfer in symmetric and non-symmetric stenotic arteries are numerically simulated considering the fluid-structure interaction (FSI) using the code ADINA. Blood ...
-
(IEEE, 2017)In the context of bio-acoustic sciences, call detection is a critical task for understanding the behaviour of marine mammals such as the blue whale species (Balaeonoptera musculus) considered in this work. In this paper ...
-
(ELSEVIER, 2008-11)In this paper, an unsupervised intra-speaker variability compensation (ISVC) method based oil Gestalt is proposed to address the problem of limited enrolling data and noise robustness in text-dependent speaker verification ...
-
(Elsevier B.V., 2018)© 2018 Elsevier B.V. We consider the problem of analyzing the structure of spectroscopic cubes using unsupervised machine learning techniques. We propose representing the target's signal as a homogeneous set of volumes ...
-
Unsupervised method for correlated noise removal for multi-wavelength exoplanet transit observations (IOP Publishing, 2017-07-01)Exoplanetary atmospheric observations require an exquisite precision in the measurement of the relative flux among wavelengths. In this paper, we aim to provide a new adaptive method to treat light curves before fitting ...
-
(IOP, 2015)We discuss the possible existence of features in both the primordial power spectrum and bispectrum generated during a stage of single eld cosmic in ation. We argue that there are two main classes of features: those ...

Unusual Galactic HiiRegions at the Intersection of the Central Molecular Zone and the Far Dust Lane (IOP Publishing, 2020)Sgr.E is a massive star formation complex found toward the Galactic center that consists of numerous discrete, compact H II regions. It is located at the intersection between the central molecular zone (CMZ) and the far ...
