(Oxford University Press, 2017)We present Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of the star-forming environment surrounding V1647 Ori, an outbursting FUor/EXor pre-MS star. Dust continuum and the (J = 2 − 1) 12CO, 13CO, ...
-
(Elsevier Ltd, 2018)System states are related, directly or indirectly, to health condition indicators. Indeed, critical system failures can be efficiently characterized through a state space manifold. This fact has encouraged the development ...
-
(Elsevier B.V., 2018)Long-established and widespread mining activities in the Northern Atacama Region of Chile have historically impacted the environment. Most notably, the Potrerillos and El Salvador mines, until 1976, were responsible for ...
-
(Public Library of Science, 2018)The HIV care cascade has improved in Latin America over the last decade. However, the influence of alcohol and noninjected drug use (NIDU) on cascade outcomes is mostly unknown. This study estimated the association of ...
-
(EDP Sciences, 2018)We study a sample of 17 $z>1.5$ C~{\sc i} absorbers observed with the ESO-VLT spectrograph X-SHOOTER. We derive metallicities, depletion onto dust, extinction by dust and analyse the absorption from Mg~{\sc ii}, Mg~{\sc ...
-
(Academic Press Inc., 2018)Based on a fundamental work of R. B. Holmes from 1973, we study differentiability properties of the metric projection onto prox-regular sets. We show that if the set is a nonconvex body with a Cp+1-smooth boundary, then ...
-
(Elsevier B.V., 2018)Many fields of study, including medical imaging, granular physics, colloidal physics, and active matter, require the precise identification and tracking of particle-like objects in images. While many algorithms exist to ...
-
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2018)Conjunctive query (CQ) evaluation is NP-complete, but becomes tractable for fragments of bounded hypertreewidth. Approximating a hard CQ by a query from such a fragment can thus allow for an efficient approximate evaluation. ...
-
(Academic Press, 2018)Different studies have demonstrated that vibration characteristics are sensitive to debonding in composite structures. Nevertheless, one of the main restrictions of vibration measurements is the number of degrees of ...
-
(Elsevier B.V., 2018)Magnetotelluric (MT) data were collected at the Laguna del Maule volcanic field (LdMVF), located in central Chile (36◦S, 70.5◦W), which has been experiencing unprecedented upward ground deformation since 2007. These data ...
-
(Institute of Physics Publishing, 2018)The electronic, vibrational and thermal properties of stoichiometric and non-stoichiometric cobalt antimonide CoSb x (x = 2.81, 2.875, and 3) are investigated by means of first principle calculations and thermal measurements. ...
-
(Elsevier Ltd, 2018)A model capable of predicting the shear response of beam-column joints subjected to seismic actions is presented. The analytical model, originally developed for walls and based on a simple physical formulation, is adapted. ...
-
(Springer Netherlands, 2018)RC structural slender walls under large seismic excitation are expected to reach base moment capacity mainly affected by the first vibration mode. However, the base shear could be affected by higher modes once yielding in ...
-
(International Society for Horticultural Science, 2018)Vegetable consumption has increased in recent years, so it is imperative for the industry to fill expectations in terms of convenience, taste and product quality. Consumers are looking for freshness and soft textures, so ...
-
(International Society for Horticultural Science, 2018)The effects of different chelated glycine calcium solutions on the quality and firmness fruit of guava fruit (Psidium guajava L.) were studied. Five sets of 45 fruits of 'Media China′ guava were submerged in different ...
-
(International Society for Horticultural Science, 2018)Olive lree productivity is highly respons1ve to radiation condit10ns, so understanding the responses of the developmental processes that determine yield, among these inflorescence and flower differentiation, is essenllal ...
-
(International Society for Horticultural Science, 2018)Aquaponics is the integration of aquaculture and hydroponic systems where, in general terms, the waste produced by aquatic organisms becomes nutrients through bacterial action for plant growth. Water consumption as well ...
-
(International Society for Horticultural Science, 2018)Safety of fresh-cut products is largely affected by the microbial load of raw material. In this sense, a hydroponic production system allows to reduce microbial contamination, as long as the quality of the used water on ...
-
(International Society for Horticultural Science, 2018)The aim of this work was to evaluate the effect of wedge and dice cut format and storage temperature on the physiological activity, firmness and organic acid and sugar content of fresh cut pears (Pyrus communis L.) 'Packham's ...
-
(International Society for Horticultural Science, 2018)Currently in the industry of fresh salads, watercress is shown as an alternative supply of gourmet products, being recognized for its high content of health promoting compounds such as antioxidants and phenolic compounds. ...
