      We report the discovery of two hot Jupiters orbiting the stars K2-237 and K2-238. We used photometric data from Campaigns 11 and 12 of the Kepler K2 mission and radial velocity data obtained using the HARPS, FEROS, and ...
    • Orive, Joseba; Sivasamy, Ramesh; Fernández de Luis, Roberto; Mosquera, Edgar; Arriortua, María I. (Royal Soc Chemistry, 2018)
      A novel 2D metal oxalatophosphite, K2Mn2II(H2O)(2)C2O4(HPO3)(2) (KMnCP), was hydrothermally synthesized and characterized. The hexagonal morphology and crystal growth faces of KMnCP were predicted by the Bravais-Friedel- ...
    • Fabry, Johan K.; Tanter, Éric Pierre; D’Hondt, Theo (ELSEVIER, 2008-05-01)
      Transaction management is a known crosscutting concern. Previous research has been conducted to express this concern as an aspect. However, such work has used general-purpose aspect languages which lack a formal foundation, ...
    • Parra Tsunekawa, Sebastián Isao; Ruiz del Solar, Javier; Vallejos, Paul (Springer, 2015)
      The generation of accurate terrain maps while navigating over off-road, irregular terrains is a complex challenge, due to the difficulties in the estimation of the pose of the laser rangefinders, which is required for the ...
    • Maldonado Alarcón, Sebastián Alejandro; Carrizosa P., Emilio; Weber, Richard (Elsevier, 2015)
      We present an unsupervised method that selects the most relevant features using an embedded strategy while maintaining the cluster structure found with the initial feature set. It is based on the idea of simultaneously ...
    • Sipiran, Iván; Bustos Cárdenas, Benjamín (Springer, 2013)
      In this paper, we present a method to detect stable components on 3D meshes. A component is a salient region on the mesh which contains discriminative local features. Our goal is to represent a 3D mesh with a set of ...
    • Flores Durán, S.N.; Peña, M.; Ruiz González, María Teresa (EDP Sciences, 2017-05)
      Aims. We present high-resolution spectroscopy of a number of planetary nebulae (PNe) and H II regions distributed along the dwarf irregular galaxy NGC3109 and compare their kinematical behavior with that of H I data. We ...
    • Ortega, M. E.; Paron, S.; Areal, M. B.; Rubio López, Mónica (EDP Sciences, 2020)
      Aims. Cometary globules, dense molecular gas structures exposed to UV radiation, are found inside HII regions. Understanding the nature and origin of these structures through a kinematic study of the molecular gas could ...
