      This study presents two specimens of Chimaeriformes from Upper Jurassic strata of central Chile. The material was recovered from Tithonian levels of the Baños del Flaco Formation and includes two different individuals, ...
    • Alegría, M.; Aliaga, J.; Jofré, P.; Ballesteros, L.; Guzmán, D.; Sotomayor Torres, Clivia Marfa; González, G.; Benavente, E. (Elsevier, 2021)
      Layered hybrid ZnO (2D) intercalated by myristic acid (MA) with (0D) CdTe quantum dots (QDs) was designed to increase the conversion efficiency of photochemical energy. The results showed that the introduction of CdTe QDs ...
    • Koch, Benjamin; Asenjo, Felipe; Hojman Guinerman, Sergio (American Physical Society, 2022)
      We revisit the observable used for the direct measurements of the electron's g factor. This is done by considering the subleading effects of the large magnetic background field and virtual Standard Model processes. We find ...
    • Díaz Forestier, Javiera; Abades Torres, Sebastián; Pohl, Nélida; Barbosa, Olga; Godoy, Karina; Svensson, Gabriella L.; Undurraga, María I.; Bravo, Camila; García, Camila; Root Bernstein, Meredith; Armesto Zamudio, Juan Jose; Celis Diez, Juan Luis (MDPI, 2021)
      Mediterranean central Chile is globally recognized as a hotspot for terrestrial biodiversity due to its high endemism and massive habitat loss. However, within the rural landscape of central Chile, significant extents ...
    • Godfrey, Stephen J.; Gutstein, Carolina Simon; Morgan III, Donald J. (Copernicus Gesellschaft MBH, Germanyc, 2021)
      A new monotypic genus of Neogene odontocete (Isoninia borealis) is named on the basis of a partial skull (CMM-V-4061). The holotype was found on the riverbed of the Meherrin River (North Carolina, USA) and probably originated ...
    • Botto Mahan, Carezza Verónica; Medel Contreras, Rodrigo Guillermo (Soc Biolgia Chile, 2021)
      The source of Darwin’s illness has been a contentious issue in the literature for almost 70 years. Different causal factors have been invoked to account for his symptoms, including Chagas disease. The Chagas hypothesis ...
    • Castañeda, Justine; Hidalgo, Yessia; Sauma Mahaluf, Daniela Macarena; Rosemblatt Silber, Mario Cesar; Bono Merino, María Rosa; Núñez, Sarah (Frontiers Media, 2021)
      The thymus is home to a significant number of resident B cells which possess several unique characteristics regarding their origin, phenotype and function. Evidence shows that they originate both from precursors that ...
    • Hojman Guiñerman, Sergio; Asenjo, Felipe A. (IOP, 2022)
      A unification in terms of exact solutions for massless Klein-Gordon, Dirac, Maxwell, Rarita-Schwinger, Einstein, and bosonic and fermionic fields of any spin is presented. The method is based on writing all of the relevant ...
    • González, Andrea; Calfio Painemal, Camila Del Pilar; Churruca, Macarena; Maccioni Baraona, Ricardo Benjamin (BMC, 2022)
      Background Alzheimer's disease is the most prevalent cause of dementia in the elderly. Neuronal death and synaptic dysfunctions are considered the main hallmarks of this disease. The latter could be directly associated to ...
    • Hernández Vázquez, E. E.; López Moreno, S.; Muñoz Sáez, Francisco Javier; Ricardo-Chávez, J. L.; Morán López, J. L. (Royal Soc Chemistry, England, 2021)
      A theoretical study of the Mn trimer adsorbed on the noble metal surfaces Au(111) and Cu(111) is reported. The calculations were performed using first-principles methods within the density functional theory and the generalized ...
    • Izquierdo, Diego; Lucchini Arteche, Giancarlo (European Mathematical Society, Suiza, 2022)
      Let q be a non-negative integer. We prove that a perfect field K has cohomological dimension at most q + 1 if, and only if, for any finite extension L of K and for any homogeneous space Z under a smooth linear connected ...
