    • Bruhn, Henning; Stein, Maya (SIAM PUBLICATIONS, 2010)
      A connected graph G is called t-perfect if its stable set polytope is determined by the non-negativity, edge and odd-cycle inequalities. More- over, G is called strongly t-perfect if this system is totally dual inte- gral. ...
    • Carballo Bello, Julio A.; Martínez Delgado, David; Navarrete, Camila; Catelan, Marcio; Muñoz Vidal, Ricardo Rodrigo; Antoja, Teresa; Sollima, Antonio (Oxford University Press, 2018)
      We present Dark Energy Camera imaging for the peculiar Galactic globular clustersNGC 1851, NGC1904 (M 79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an important contribution of stars ...
    • Quastel, Jeremy; Remenik Zisis, Daniel (Inst Mathematical Statistics, 2015)
      We prove that the random variable T = argmaxt∈R{A2(t)−t2}, where A2 is the Airy2 process, has tails which decay like e−ct3 . The distribution of T is a universal distribution which governs the rescaled endpoint of directed ...

      Parkinson's disease is the second most common neurodegenerative disorder, leading to the progressive decline of motor control due to the loss of dopaminergic neurons in the substantia nigra pars compacta. At the molecular ...
    • Alcorta, Jaime; Alarcón Schumacher, Tomás; Salgado, Oscar; Diez, Beatriz (Frontiers Media, 2020)
      Several cyanobacterial species are dominant primary producers in hot spring microbial mats. To date, hot spring cyanobacterial taxonomy, as well as the evolution of their genomic adaptations to high temperatures, are poorly ...
    • Fabry, Johan K.; Dinkelaker, Tom; Noyé, Jacques; Tanter, Éric Pierre (Assoc Computing Machinery, 2015)
      Domain-Specific Aspect Languages (DSALs) are Domain-Specific Languages (DSLs) designed to express crosscutting concerns. Compared to DSLs, their aspectual nature greatly amplifies the language design space. We structure ...
    • Travieso Torres, Juan Carlos; Duarte Mermoud, Manuel; Beytia Cancino, Orlando (Wiley, 2017)
      The techniques of Taylor polynomial approximation (TPA) and adaptive passivity-based controller (APBC) are combined in this study and applied to the level regulation of a conical tank. The design and comparative experimental ...
