      We show that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves. Moreover, at nonzero temperatures the incoming thermally occupied spin ...
    • Cassels Niven, Bruce (Natural Product Incorporation, 2019)
      Alkaloids of the Cactaceae have been studied for the last 120 years. The first half of that period provided the "classic" compounds, after which a large number of usually very similar analogs were isolated or determined ...
    • Billi, Marco; Blanco, Gustavo; Urquiza, Anahí (Springer Netherlands, 2019)
      Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the ...

    • Guerrero Gatica, Matías; Aliste, Enrique; Simonetti Zambelli, Javier Andrés (MDPI AG, 2019)
      There are two barriers to accomplishing restoration of ecosystems: insufficient information about historical baselines to guide restoration, and shifts between the actual baselines and perceptions about historical conditions. ...
    • Clemens, Michael A.; Montenegro Muñoz, Claudio; Pritchett, Lant (MIT Press Journals, 2019)
      Large international differences in the price of labor can be sustained by differences between workers or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds ...
