A co survey in planet-forming disks: characterizing the gas content in the epoch of planet formation (The American Astronomical Society., 2014-07-31)We carried out a 12CO(3-2) survey of 52 southern stars with a wide range of IR excesses (L IR/L *) using the single-dish telescopes APEX and ASTE. The main aims were (1) to characterize the evolution of molecular gas in ...
-
(EDP Sciences, 2013-05)Context. The molecular gas in protoplanetary disks can be traced with single-dish instruments in low J rotational lines of CO, in systems clear of coincident extended emission. Other rotational lines of CO also sample the ...
-
(EDP SCIENCES S A, 2008-02)Context. Studying molecular gas in the central regions of the star burst galaxies NGC4945 and Circinus enables us to characterize the physical conditions and compare them to previous local and high-z studies. Aims. We ...

(UNIV CHICAGO PRESS, 2008-04-10)Using the APEX submillimeter telescope we have investigated the (CO)-C-12(3-2) emission in five face-on nearby barred spiral galaxies, where three of them are high surface brightness galaxies (HSBs) lying at the Freeman ...
-
(Springer, 2012)In oxide copper deposits, the acid soluble copper represents the fraction of total copper recoverable by heap leaching. Two difficulties often complicate the joint modeling and simulation of total and soluble copper ...

(American Physical Society, 2016)The emergence of clustering and coarsening in crowded ensembles of self-propelled agents is studied using a lattice model in one dimension. The persistent exclusion process, where particles move at directions that change ...
-
(2005)The dynamics of one-dimensional Cahn-Hilliard model is studied. The stationary and particle-type solutions, the bubbles, are perused as a function of initial conditions, boundary conditions, and system size. We characterize the ...
-
(American Meteorological Society, 2016)The climatology and recent trends of low-level coastal clouds at three sites along the northern Chilean coast (18.3 degrees-23.4 degrees S) are documented based upon up to 45 years of hourly observations of cloud type, ...
-
(American Geophysical Union, 2011-04-14)We reconstructed a high‐resolution, alkenone‐based sea surface temperature (SST) record spanning the last ca. 150 years, from a sediment core retrieved within the main upwelling zone off Peru. A conspicuous SST decline ...
-
(2002-01)The typical conditions of the eastern boundary of the subtropical anticyclone [e.g., well-defined marine boundary layer (MBL), equatorward low-level flow] that prevail along the mountainous west coast of subtropical South ...

(2011-01)On February 27, 2010 at 03:34:08 AM an Mw8.8 earthquake, with epicenter located off Cobquecura (73.24°W; 36.29°S), severely hit Central Chile. The tsunami waves that followed this event affected the coastal regions between ...

-
(2008)The west coast of subtropical South America is characterized by a semi-arid climate and very persistent southerly winds that often exhibit a low-level jet structure. The nearly alongshore flow forces coastal and offshore ...
-
(Institute of Electrical and Electronics Engineers Inc., 2019)© 2012 IEEE. We propose a novel transmission scheme, suitable to Internet of Things, which sends coded redundant information in independent packets. The results indicate that this scheme outperforms, in terms of reliability, ...

(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2006-08)CODELCO's Chuquicamata Copper Smelter, located in Chile, must meet an environmental standard established in 2002 that limits the sulfur emissions from the copper-production process. This regulation placed new restrictions ...
-
(ELSEVIER, 2006-12-15)In this article we study a special class of sliding block maps that we call variable block maps.We characterize the subsets of ï¬ nite and inï¬ nite sequences that can be obtained as the image of another subset of symbolic ...

Cognitive impact evaluation of multimodal interfaces for blind people: Towards a systematic review (Springer Verlag, 2018)Visual disability has a major impact on people’s quality of life. Although there are many technologies to assist people who are blind, most of them do not necessarily guarantee the effectiveness of the intended use. Then, ...
-
(Elsevier, 2012-01)Traditional approaches to predict a second-order stationary vector random field include simple and ordinary cokriging, depending on whether or not the mean values of the vector components are assumed to be known. This paper ...

(2013-08)Pig trypsin is routinely used as a biotechnological tool, due to its high specificity and ability to be stored as an inactive stable zymogen. However, it is not an optimum enzyme for conditions found in wound debriding ...
