    • Can we improve CIV-based single-epoch black hole mass estimations? 
      Mejía Restrepo, Julián; Trakhtenbrot, B.; Lira Teillery, Paulina; Netzer, H. (Oxford University Press, 2018)
      In large optical surveys at high redshifts (z > 2), the C IV λ1549 broad emission line is the most practical alternative to estimate the mass (MBH) of active supermassive black holes. However, mass determinations obtained ...

    • Canonical forms for isomorphic and equivalent RDF graphs: algorithms for leaning and labelling blank nodes 
      Hogan, Aidan (ASSOC COMPUTING MACHINERY, 2017)
      Existential blank nodes greatly complicate a number of fundamental operations on RDF graphs. In particular, the problems of determining if two RDF graphs have the same structure modulo blank node labels (i.e. if they are ...
    • Canonicalisation of monotone SPARQL queries 
      Salas, Jaime; Hogan, Aidan (Springer Verlag, 2018)
      Caching in the context of expressive query languages such as SPARQL is complicated by the difficulty of detecting equivalent queries: deciding if two conjunctive queries are equivalent is NP-complete, where adding further ...

      One of the current challenges in structural health monitoring (SHM) is to take the most advantage of large amounts of data to deliver accurate damage measurements and predictions. Deep Learning methods tackle these ...
    • Carbon monoxide in clouds at low metallicity in the dwarf irregular galaxy WLM

      Aims. We analyze the carbon monoxide emission around the starWR 16 aiming to study the physical characteristics of the molecular gas linked to the star and to achieve a better understanding of the interaction between ...
    • Carbon monoxide oxidation on Iridium (111) surfaces driven by strongly colored noise 
      Cisternas, J.; Lecaros, R.; Wehner, S. (SPRINGER, 2011-03)
      The influence of external colored noise on the carbon monoxide oxidation on Iridium(111) surfaces is examined. The noise is introduced in the reaction by randomly varying the composition of the gas flow that keeps the ...

    • Carleman inequalities and inverse problems for the Schrodinger equation 
      Mercado, Alberto; Osses Alvarado, Axel; Rosier, Lionel (ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2008-01)
      In this Note, we derive new Carleman inequalities for the evolution Schrodinger equation under a weak pseudoconvexity condition, which allows us to use weights with a linear spatial dependence. As a result, less restrictive ...
