    Article
    Restricted access - publisher's policy
    Droughts and climate-change-driven warming are leading to more frequent and intense wildfires1,2,3, arguably contributing to the severe 2019–2020 Australian wildfires4. The environmental and ecological impacts of the fires ...
  • BioFVM-X: an MPI+OpenMP 3-D simulator for biological systems 

    Saxena, Gaurav; Ponce De Leon, Miguel; Montagud, Arnau; Vicente Dorca, David; Valencia, Alfonso (Springer, 2021)
    Conference report
    Open Access
    Multi-scale simulations require parallelization to address large-scale problems, such as real-sized tumor simulations. BioFVM is a software package that solves diffusive transport Partial Differential Equations for 3-D ...
  • Experimental correlation of mechanical properties of the Ti-6Al-4V alloy at different length scales 

    Tuninetti, Víctor; Jaramillo, Andrés F.; Riu Perdrix, Guiomar; Mateo García, Antonio Manuel; Roa Rovira, Joan Josep (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-07)
    Article
    Open Access
    This article focuses on a systematic study of a Ti-6Al-4V alloy in order to extensively characterize the main mechanical properties at the macro-, micro- and submicrometric length scale under different stress fields. ...
  • The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients 

    Torres, Antoni; Motos, Anna; Riera, Jordi; Fernández Barat, Laia; Ceccato, Adrián; Pérez Arnal, Raquel; Garcia Gasulla, Dario (BMC, 2021)
    Article
    Open Access
    Background Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three ...
  • Preliminary assessment of a polygeneration system based on a concentrated photovoltaic thermal (CPVT) solar collectors 

    Castro González, Jesús; Rigola Serrano, Joaquim; Kizildag, Deniz; Oliet Casasayas, Carles (Technishe Universität Berlin, 2021)
    Conference report
    Open Access
    ECOSun project has as main objective a cost reduction of electricity and heat co-generation via a Concentrated Photovoltaic/Thermal (CPV-T) system by applying low-cost materials and advanced industrial manufacturing methods. ...
  • Surface tension and contact angle measurement of LiBr and Carrol solution 

    Zheng, Jian; Castro González, Jesús; Oliet Casasayas, Carles; Oliva Llena, Asensio (Technishe Universität Berlin, 2021)
    Conference report
    Open Access
    The surface tension and contact angle play a relevant role in the heat and mass transfer for the absorption system working pairs. However, LiBr aqueous solution surface tension/contact angle studies are limited and for ...
  • Large-eddy simulations of the flow on an aerofoil with leading-edge imperfections 

    Kumar, Vishal; Piomelli, Ugo; Lehmkuhl Barba, Oriol (Taylor and Francis, 2021)
    Article
    Restricted access - publisher's policy
    We performed large-eddy simulations of the flow over an aerofoil to understand the effects of leading-edge roughness designed to mimic ice accretion. The roughness elements protrude outside the boundary layer, which, near ...
  • Rainfall regime trends at annual and monthly scales in Catalonia (NE Spain) and indications of CO2 emissions effects 

    Lana Pons, Francisco Javier; Casas Castillo, M. del Carmen; Rodríguez Solá, Raúl; Serra de Larrocha, Carina; Martínez Santafé, Maria Dolors; Kirchner Amor, Ricard (2021-09-16)
    Article
    Open Access
    The pluviometric regime in the Western Mediterranean and concretely in Catalonia (NE Spain) is characterised by irregular amounts at monthly and annual scales, sometimes with copious short episodes causing foods and, ...
  • Electrical tunability ofterahertz nonlinearity in graphene 

    Kovalev, Sergey; Hafez, Hassan A.; Tielrooij, Klass-Jan; Deinert, Jan-Christoph; Ilyakov, Igor; Awari, Nilesh; Alcaraz, David; Soundarapandian, Karuppasamy; Saleta, David; Germanskiy, Semyon; Chen, Min; Bawatna, Mohammed; Green, Bertram; Koppens, Frank H. L.; Mittendorff, Martin; Bonn, Mischa; Gensch, Michael; Turchinovich, Dmitry (Science, 2021-04-07)
    Article
    Open Access
    Graphene is conceivably the most nonlinear optoelectronic material we know. Its nonlinear optical coefficients in the terahertz frequency range surpass those of other materials by many orders of magnitude. Here, we show ...
  • Controlling mid-infrared plasmons in graphene nanostructures through post-fabrication chemical doping 

    Paulillo, Bruno; Bareza, Nestor Jr; Pruneri, Valerio (IOP, 2021-05-07)
    Article
    Open Access
    Engineering the doping level in graphene nanostructures to yield controlled and intense localized surface plasmon resonance (LSPR) is fundamental for their practical use in applications such as molecular sensing for point ...
  • The dilating method to obtain dense cayley digraphs on finite abelian groups 

    Aguiló Gost, Francisco de Asis L.; Fiol Mora, Miquel Àngel; Pérez Mansilla, Sonia (2021-01-01)
    Article
    Open Access
    A geometric method for obtaining an infinite family of Cayley digraphs of constant density on finite abelian groups is presented. The method works for any given degree d ≥ 2, and it is based on consecutive dilates of a ...
  • OpenMP taskloop dependences 

    Maroñas Bravo, Marcos; Teruel García, Xavier; Beltran, Vincenç (Springer, 2021)
    Conference report
    Open Access
    Exascale systems will contain multicore/manycore processors with high core count in each node. Therefore, using a model that relaxes the synchronization, such as data-flow, is crucial to adequately exploit the potential ...
