      We present a detailed study of the massive star-forming region G35.2-0.74N with Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm multi-configuration observations. At 0.'' 2 (440 au) resolution, the continuum ...
    • López Saavedra, Celso; Bronfman Aguiló, Leonardo; Nyman, L.-Å.; May Humeres, Jorge; Garay Brignardello, Guido (EDP SCIENCES S A, 2011-10)
      Context. Massive condensations in giant molecular clouds (GMCs) are linked to the formation of high mass stars, which are the principal source of heavy elements and UV radiation, playing an important role in the evolution ...
    • Bronfman Aguiló, Leonardo (SPRINGER, 2008-01)
      During the past decade we have compiled a large molecular line data base of massive star forming regions in the southern Milky Way. These regions are confined into giant molecular clouds that trace the galactic spiral arms. ...
    • Garay Brignardello, Guido; Lizano, Susana (1999-09)
      Cloud environment is thought to play a critical role in determining the mechanism of formation of massive stars. In this contribution we review the physical characteristics of the environment around recently formed massive ...
    • Bian, Fuyan; Kewley, Lisa J.; Dopita, Michael A.; Blanc Mendiberri, Guillermo (Institute of Physics, 2017)
      We revisit the evolution of the mass–metallicity relation of low- and high-redshift galaxies by using a sample oflocal analogs of high-redshift galaxies. These analogs share the same location of the UV-selected ...
    • Caraballo, L. E.; Ochoa, C.; Pérez Lantero, P.; Rojas Ledesma, J. (Springer, 2017)
      Let S be a point set in the plane such that each of its elements is colored either red or blue. A matching of S with rectangles is any set of pairwise-disjoint axis-aligned closed rectangles such that each rectangle contains ...
    • Cossio-Rodriguez, Romina; Cocroft, Reginald B.; Niemeyer, Hermann M.; Pinto, Carlos F. (Blackwell Publishing Ltd, 2019)
      1. In treehoppers in which courtship has been studied, males initiate the search for females by periodically emitting a vibrational signal. The responses by the female are used by males as a beacon and give rise to a duet. ...
    • Heyden, Stefanie; Nagler, Andreas; Bertoglio, Cristóbal; Biehler, Jonas; Gee, Michael W.; Wall, Wolfgang A.; Ortiz, Michael (Elsevier, 2015)
      A key element of the cardiac cycle of the human heart is the opening and closing of the four valves. However, the material properties of the leaflet tissues, which fundamentally contribute to determine the mechanical ...
    • Sales, Francisco; Peralta, Oscar A.; Narbona, Eileen; McCoard, Sue; Lira, Raúl; Reyes Solovera, Mónica de los; González Bulnes, Antonio; Parraguez Gamboa, Víctor (MDPI, 2019)
      Twinning and maternal nutritional restriction leads to fetal hypoxia, oxidative stress, and intrauterine growth restriction (IUGR) in near-term sheep pregnancies. Our aim was to determine the effect of oral supplementation ...
    • Cuevas, Evelyn; Courdurier, Matías; Osses Alvarado, Axel; Castañeda Zeman, Víctor; Palacios, Benjamín; Härtel, Steffen (IOP Publishing, 2020)
      We study an inverse problem for light sheet fluorescence microscopy (LSFM), where the density of fluorescent molecules needs to be reconstructed. Our first step is to present a mathematical model to describe the measurements ...
    • Shene, C.; Lucero Alday, Augusto; Andrews Farrow, Bárbara; Asenjo de Leuze, Juan (JOHN WILEY & SONS INC, 2006-11-05)
      Elution curves in ionic exchange chromatography (IEC) for a three-protein mixture (alpha-lactoalbumin, ovalburnin, and P-lactoglobulin), carried out under different flow rates and ionic strength conditions, were simulated ...
