(Amer Meteorological Soc, 2020)In desert environments, intense radiative cooling of the surface during the night leads to rapid cooling of the adjacent air, resulting in a strong temperature inversion conducive to cold-air-pool formation. In this work ...
-
(Materials & Energy Research Center-Merc, 2017)In this work, we use Drude-Lorents model description to study the radiation of a charged particles moving in a homogeneous dispersive medium. A suitable quantized electromagnetic field for such medium is utilized to obtain ...

Investigation of the conspicuous infrared star cluster and star-forming region "RCW 38 IR cluster" (2008-01)The infrared star cluster RCW 38 IR Cluster, which is also a massive star-forming region, is investigated. The results of observations with the SEST (Cerro La Silla, Chile) telescope on the 2.6-mm (CO)-C-12 spectral line ...

(Oxford University Press, 2018)We present observations of the Herbig Ae star HD 169142 with the VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) (K1K2 and H2H3 bands) and the Integral Field Spectrograph (IFS) (Y, J and H bands). ...
-
(Elsevier, 2015)The conservation of archaeological heritage is of major importance for preserving the scientific, ethnographic and artistic values of past cultures. Once archaeological sites are exposed after being buried for centuries, ...
-
(PERGAMON-ELSEVIER SCIENCE, 2010-11-01)Despite its potential economic and environmental importance, the study of trace metals in supergene (secondary) Cu-sulfides has been seriously overlooked in the past decades. In this study, the concentration and mineralogical ...
-
(Elsevier, 2016)Iodine enrichment in the Atacama Desert of northern Chile is widespread and varies significantly between reservoirs, including nitrate-rich "caliche" soils, supergene Cu deposits and marine sedimentary rocks. Recent studies ...
-
(SPRINGER, 2009-08)Recent studies have suggested the involvement of highly saline deep formation waters that modified preexisting Cu assemblages to form atacamite during supergene oxidation of Cu deposits in the Atacama region. In this report, ...
-
(Blackwell, 2006)We consider a fast solar wind-type plasma consisting of electrons, a protons background, and a much more tenuous alpha particle beam. It is shown that such system is unstable against ion acoustic-like waves triggered by ...
-
(EDP Sciences, 2013)Context. Ionising stars reshape their original molecular cloud and impact star formation, leading to spectacular morphologies such as bipolar nebulae around Hii regions. Molecular clouds are structured in filaments where ...
-
(Springer, 2016)The lithosphere and the atmosphere/ionosphere continuously exchange energy through various coupling mechanisms. In particular, the earth surface displacement caused by earthquakes, volcanoes and tsunamis can manifest as ...
-
IoT-RECSM—resource-constrained smart service migration framework for IoT edge computing environment (MDPI, 2020)The edge-based computing paradigm (ECP) becomes one of the most innovative modes of processing distributed Interneit of Things (IoT) sensor data. However, the edge nodes in ECP are usually resource-constrained. When more ...
-
(AGU Publications, 2015)The subduction zone in northern Chile is a well-identified seismic gap that last ruptured in 1877. On 1 April 2014, this region was struck by a large earthquake following a two week long series of foreshocks. This study ...
-
(American Astronomical Society, 2015)We present the results of continuum and 12CO(3–2) and CH3OH(7–6) line observations of IRAS 16547−4247 made with the Atacama Large Millimeter/submillimeter Array (ALMA) at an angular resolution of ∼0. 5. The 12CO(3–2) ...

(The American Astronomical Society, 2015-01-10)We present the results of continuum and 12CO(3–2) and CH3OH(7–6) line observations of IRAS 16547−4247 made with the Atacama Large Millimeter/submillimeter Array (ALMA) at an angular resolution of ∼0. 5. The 12CO(3–2) ...
-
(Frontiers Media S.A., 2019)The IRE1α/XBP1s signaling pathway is an arm of the unfolded protein response (UPR) that safeguards the fidelity of the cellular proteome during endoplasmic reticulum (ER) stress, and that has also emerged as a key regulator ...
-
(IEEE, 2022)Iris is one of the most accurate biometrics. This has led to the successful development of large-scale applications. However, with population growth, and new international applications, datasets are constantly increasing ...
-
(American Physiological Society, 2015)Recent evidence shows that iron induces the endocytosis of the iron transporter dimetal transporter 1 (DMT1) during intestinal absorption. We, and others, have proposed that iron-induced DMT1 internalization underlies the ...
-
(Royal Soc. Chemistry, 2021)Siderophores are iron-chelating compounds that aid iron uptake, one of the key strategies for microorganisms to carve out ecological niches in microbially diverse environments. Desferrioxamines are the principal siderophores ...
-
(2015)Train algebras were introduced by Etherington in 1939 as an algebraic framework for treating genetic problems. The aim of this paper is to study the representations and irreducible representations of power-associative ...
