      © 2018 Elsevier B.V. In mammals, the cochlear sensory epithelium becomes quiescent early during development. After the first postnatal week, there is no cell replacement or proliferation, and severe damage leads to permanent ...
    • Hernández, Cecilia; Rodriguez, M. Andrea; Marín, Mauricio (Springer Berlin Heidelberg, 2008-01)
      In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers.We present distribution and fault tolerance ...
    • Koenigsberg, Oded; Kohli, Rajeev; Montoya Moreira, Ricardo (INFORMS, 2010-03)
      We describe a model examining how a firm might choose the package size and price for a product that deteriorates over time. Our model considers four factors: (1) the usable life of the product, (2) the rates at which ...
    • Gomila, Rodrigo; Arancibia, Gloria; Mery, Domingo; Nehler, Mathias; Bracke, Rolf; Morata Céspedes, Diego (Elsevier, 2019)
      Fault zone permeability and the real 3D-spatial distribution of the fault-related fracture networks are critical in the assessment of fault zones behavior for fluids. The study of the real 3D-spatial distribution of the ...
    • Rivera Rosado, Huber; Le Roux, Jacobus; Sánchez Caballero, Lizeth; Marino-Martínez, Jorge; Salazar, Christian; Barragán Bohorquez, Jenny (Elsevier, 2018-10)
      The Cretaceous black shales of Colombia are among the most important successions in the north of South America and have attracted the attention of many geoscientists and exploration companies over the last few decades, ...
    • Vasconcelos, Paulo M.; Reich Morales, Martín; Shuster, David L. (Mineralogical Soc. Amer., 2015)
      Supergene metal deposits host a comprehensive record of climate-driven geochemical reactions that may span the entire Cenozoic. Products of these reactions can be dated by a variety of radiogenic isotopic methods, such as ...
