(Elsevier B.V., 2019)© 2018 The Author(s)It is generally acknowledged in the environmental sciences that the choice of a computational model impacts the research results. In this study of a flood and drought event in the Swiss Thur basin, we ...
-
(Springer, 2018)Epi-Lipschitz sets in normed spaces are represented as sublevel sets of Lipschitz functions satisfying a so-called qualification condition. Canonical representations through the signed distance functions associated with ...
-
(2013)The Liquiñe-Ofqui fault zone (LOFZ) in the Patagonian Andes is an active major transpressional intra-arc fault system along which Quaternary faulting and volcanism develop. Subaerial and submarine geomorphologic and structural ...
-
(Frontiers Media, 2022)In a period of high rates of glacier retreat, increasing meltwater discharge from tidewater glaciers can influence marine fjord ecosystems due to increase sediment delivery and accumulation rates in the proglacial environment. ...
-
(JOHN WILEY & SONS INC, 2006-03-15)Copper-embedded low-density polyethylene (LDPE) composites were fabricated using different copper concentrations in the polymer matrix. The copper particles were spherical with a mean particle size between 200 and 300 run. ...
-
(IOP Publishing Ltd, 2017)We observe the high-mass X-ray binary (HMXB) BP Cru using interferometry in the near-infrared K band with VLTI/GRAVITY. Continuum visibilities are at most partially resolved, consistent with the predicted size of the ...
-
(EDP Sciences, 2014)We report the first detection of submillimeter water maser emission toward water-fountain nebulae, which are post-AGB stars that exhibit high-velocity water masers. Using APEX we found emission in the ortho-H2O (1029 → 936) ...
-
(EDP SCIENCES S A, 2008-04)Context. Star formation at earlier cosmological times took place in an interstellar medium with low metallicity. The Large Magellanic Cloud (LMC) is ideally suited to study star formation in such an environment. Aims. ...
-
(UNIV CHICAGO PRESS, 2008-04)We have carried out submillimeter (CO)-C-12(J = 3-2) observations of six giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10 m submillimeter telescope at a spatial resolution of 5 pc and very ...
-
(Universidad de Chile, 2012)Presentamos datos a 870 mu obtenidos con el telescopio APEX en la SMC, LMC y puente Magallanico, obteniendo imagenes con 22 .4'' de resolucion para 9 nubes moleculares gigantes. Usamos estos datos en combinacion con ...
-
(AMER Geophysical Union, 2016)The emission of mineral dust aerosols in arid and semiarid regions is a complex process whose representation in atmospheric models remains crude, due to insufficient knowledge about the aerosol lifting process itself, the ...

-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-08)A system to prevent subscription fraud in fixed telecommunications with high impact on long-distance carriers is proposed. The system consists of a classification module and a prediction module. The classification module ...
-
(Universidad de Chile, 2020)En este trabajo es de interés el estudio de la dinámica simbólica sobre los grupos de Baumslag-Solitar solubles no-abelianos BS(1,N), N>= 2, a través de la comprensión de cómo la estructura de dichos grupos fuerza ...
-
(Universidad de Chile, 2014)La presente memoria tiene como objetivo estudiar subshifts generados por sustituciones multidimensionales. Los sistemas dinámicos generados por sustituciones unidimensionales han sido ampliamente estudiados y existe una ...
-
(Universidad de Chile, 2022)El objetivo de este trabajo es estudiar las propiedades dinámicas de los subshifts de tipo finito definidos sobre grupos virtualmente-$\mathbb{Z}$. Éstos son una clase de grupos finitamente generados caracterizados por ...
-
(SAGE Publications Ltd, 2019)Throughout history people have been affected by disaster events such as earthquakes, tsunamis, floods and landslides, with devastating effects for cities and towns around the world. Since the 1990s, post-disaster reconstruction ...
-
(Univ Suceava, Fac Electrical Eng, 2016)A novel family of Nyquist-I pulses called iPOWER is proposed with a new design parameter. that provides an extra degree of freedom for a certain roll-off factor, a. The proposed pulse is examined and compared with other ...
-
(Universidad de Chile, 2019)Desde 2013 está operando el Programa de Subsidio de Arriendo, el único que declara dentro de sus propósitos acercar a su población objetivo a localizaciones con mayores oportunidades en su entorno urbano, buena conexión a ...
