• Strong algorithms for the ordinal matroid secretary problem 

  Soto San Martín, José Antonio; Turkieltaub, Abner; Verdugo, Víctor (Informs, 2021)

  In the ordinal matroid secretary problem (MSP), candidates do not reveal numerical weights, but the decision maker can still discern if a candidate is better than another. An algorithm alpha is probability-competitive if ...
• Memoria colectiva de las experiencias de organización social en salud durante el período de dictadura: ... 

  Espinoza Villarroel, Pamela (Universidad de Chile, 2021)

  Uno de los procesos sociopolíticos que marcó la memoria de nuestro país y generó profundas consecuencias en diferentes niveles en las últimas décadas fue la dictadura cívico militar, la cual se extendió de septiembre ...
• The chemical inventory of the planet-hosting disk PDS 70 

  Facchini, Stefano; Teague, Richard; Bae, Jaehan; Benisty, Myriam; Keppler, Miriam; Isella, Andrea (IOP, 2021)

  As host to two accreting planets, PDS 70 provides a unique opportunity to probe the chemical complexity of atmosphere-forming material. We present ALMA Band 6 observations of the PDS 70 disk and report the first chemical ...
• The 21st-century fate of the Mocho-Choshuenco ice cap in southern Chile 

  Scheiter, Matthias; Schaefer, Marius; Flández, Eduardo; Bozkurt, Deniz; Greve, Ralf (Copernicus Gesellschaft MBH, 2021)

  Glaciers and ice caps are thinning and retreating along the entire Andes ridge, and drivers of this mass loss vary between the different climate zones. The southern part of the Andes (Wet Andes) has the highest abundance ...
• On the dynamics of zero-speed solutions for camassa-holm-type equations 

  Alejo, Miguel A.; Cortez, Manuel Fernando; Kwak, Chulkwang; Muñoz, Claudio (Oxford, 2021)

  In this paper, we consider globally defined solutions of Camassa–Holm (CH)-type equations outside the well-known nonzero-speed, peakon region. These equations include the standard CH and Degasperis–Procesi (DP) equations, ...
