      The title ionic zinc - acetate complex, [Zn(C2H3O2)(C12H12N2) (2)](2)(S3O6) center dot 5H(2)O, contains a ZnN4O2 nucleus provided by the three bidentate ligands acting in a chelating mode. The trithionate unit, in turn, ...
    • Abriola, Sergio; Barceló Baeza, Pablo; Figueira, Diego; Figueira, Santiago (AI Access Foundation, 2018)
      Bisimulation provides structural conditions to characterize indistinguishability from an external observer between nodes on labeled graphs. It is a fundamental notion used in many areas, such as verification, graph-structured ...
    • Mujica Fernández, Nicolás; Lathrop, Daniel P. (ELSEVIER SCIENCE, 2005-10-01)
      We report on experimental observations of a gravity-wave instability forced by a highly turbulent free-surface Taylor-Couette flow. We observe a subcritical bifurcation from a highly turbulent base state, the mean flow of ...
    • Dávila, Juan; Pino Manresa, Manuel del; Musso, Mónica (SPRINGER, 2011-04)
      In a bounded domain Omega subset of R(2) with smooth boundary we consider the problem Delta U =0 in Omega, du/dv = i/epsilon f(u) on d Omega where nu is the unit normal exterior vector, epsilon > 0 is a small parameter ...
    • Palacios Jativa, Pablo Geovanny; Azurdia Meza, Cesar Augusto; Zabala Blanco, David; Gutiérrez, Carlos A.; Sánchez, Iván; Castillo Soria, Francisco R.; Seguel, Fabián (Elsevier, 2022)
      Analytical expressions of the statistical distribution of the underground mining visible light communication (UMVLC) square-channel gain are derived considering scattering, shadowing, and a random position and orientation ...
    • Crochemore, Maxime; Iliopoulos, Costas; Navarro, Gonzalo; Pinzon, Yoan; Salinger, Alejandro (SPRINGER-VERLAG BERLIN, 2003)
      delta, gamma)-Matching is a string matching problem with applications to music retrieval. The goal is, given a pattern P-1...m and a text T-1...n on an alphabet of integers, find the occurrences P' of the pattern in the ...
    • Hyyro, Heikki; Navarro, Gonzalo (SPRINGER, 2005-01)
      We present a new bit-parallel technique for approximate string matching. We build on two previous techniques. The first one, BPM (Myers, 1999), searches for a pattern of length m in a text of length n permitting k differences ...
    • Rowe, Penny M.; Cordero, Raul R.; Warren, Stephen G.; Stewart, Emily; Doherty, Sarah J.; Pankow, Alec; Schrempf, Michael; Casassa, Gino; Carrasco, Jorge; Pizarro, Jaime; MacDonell, Shelley; Damiani, Alessandro; Lambert, Fabrice; Rondanelli, Roberto; Huneeus Lagos, Nicolás; Fe (Nature Publishing Group, 2019)
      Vertical profiles of black carbon (BC) and other light-absorbing impurities were measured in seasonal snow and permanent snowfields in the Chilean Andes during Austral winters 2015 and 2016, at 22 sites between latitudes ...
    • Valle, Luciano del; Prieto, Joaquín; Escala Astorquiza, Andrés (Wiley, 2019)
      We study the gas accretion and orbital decay of super-massive black hole (SMBH) pairs in the nuclear region of galaxy merger remnants, where a large amount of gas is expected to accumulate. For that purpose, we perform ...
    • Prieto, Joaquín; Escala Astorquiza, Andrés Felipe; Privon, George C.; D'Etigny, Juan (Oxford, 2021)
      Using parsec scale resolution hydrodynamical adaptive mesh refinement simulations, we have studied the mass transport process throughout a Galactic merger. The aim of such study is to connect both the peaks of mass accretion ...
    • Netzer, Hagai; Lira Teillery, Paulina; Trakhtenbrot, Benny; Shemmer, Ohad; Cury, Iara (2007-12-20)
      We present new H- and K-band spectroscopy of 15 high-luminosity active galactic nuclei (AGNs) at redshifts 2.3Y3.4 obtained with Gemini South.We combined the data with spectra of an additional 29 high-luminosity sources to ...
    • Trakhtenbrot, Benny; Netzer, Hagai; Lira Teillery, Paulina; Shemmer, Ohad (IOP Publishing., 2011-03-20)
      We present newH-band spectroscopy for a flux-limited sample of 40 z 4.8 active galactic nuclei, selected from the Sloan Digital Sky Survey. The sample probably contains the most massive active black holes (BHs) at this ...
    • Woo, Jong-Hak; Urry, C. Megan; van der Marel, Roeland P.; Lira Teillery, Paulina; Maza Sancho, José (2005-10-01)
      We report stellar velocity dispersion measurements for a sample of 28 active galactic nucleus (AGN) host galaxies, including our previous work. Using the mass-dispersion (M.- ) and the fundamental plane relations, ...

(EDP Sciences, 2019)
      Context. Young planets are expected to cause cavities, spirals, and kinematic perturbations in protostellar disks that may be used to infer their presence. However, a clear detection of still-forming planets embedded within ...
    • Conca Rosende, Carlos; Orive, Rafael; Vanninathan, Muthusamy (2002)
      The classical problem of homogenization of elliptic operators with periodically oscillating coefficients is revisited in this paper. As is well known, the homogenization process in a classical framework is concerned with ...
    • Conca Rosende, Carlos; Orive, R.; Vanninathan, Muthusamy (IOS PRESS, 2005-01)
      The classical problem of homogenization deals with elliptic operators in periodically oscillating media of small period epsilon>0 and the asymptotic behavior of solution u(epsilon) of boundary value problems associated ...
    • Conca Rosende, Carlos; Gómez, D.; Lobo, M.; Pérez, E. (2005)
