  • OpenFOAM computational fluid dynamics simulations of thermal wind generation in mountain/valley configurations 

    Athota, Rathan Babu; Villardi de Montlaur, Adeline de; Arias Calderón, Santiago; Rojas Gregorio, José Ignacio (2021)
    Conference report
    Open Access
    Thermal winds appear in mountainous areas and valleys due to temperature gradients caused by the buoyancy effects associated with the diurnal heating-cooling cycle of the lower atmosphere. These winds develop over complex ...

  • Error estimation for proper generalized decomposition solutions: a dual approach 

    Reis, Jonatha; Moitinho de Almeida Pereira, José Paulo; Díez, Pedro; Zlotnik, Sergio (2020-12-15)
    Article
    Restricted access - publisher's policy
    The Proper Generalized Decomposition is a well established reduced order method, used to efficiently obtain approximate solutions of multi-dimensional problems in a procedure that controls the effects of the "curse of ...

  • Self-propulsion of active colloids via ion release: theory and experiments 

    Corato, Marco de; Arqué, Xavier; Patiño, Tania; Arroyo Balaguer, Marino; Sanchez Ordoñez, Samuel; Pagonabarraga, Ignacio (American Institute of Physics (AIP), 2020-03-13)
    Article
    Open Access
    We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical ...

  • High-order HDG formulation with fully implicit temporal schemes for the simulation of two-phase flow through porous media 

    Costa Solé, Albert; Ruiz Gironès, Eloi; Sarrate Ramos, Josep (John Wiley & sons, 2021-03-17)
    Article
    Restricted access - publisher's policy
    We present a memory-efficient high-order hybridizable discontinuous Galerkin (HDG) formulation coupled with high-order fully implicit Runge-Kutta schemes for immiscible and incompressible two-phase flow through porous ...

  • Development of a new 3D hybrid model for epithelia morphogenesis 

    Ioannou, Filippos; Dawi, Malik Ali A.; Tetley, Rob; Mao, Yanlan; Muñoz Romero, José (Frontiers Media SA, 2020-05-05)
    Article
    Open Access
    Many epithelial developmental processes like cell migration and spreading, cell sorting, or T1 transitions can be described as planar deformations. As such, they can be studied using two-dimensional tools and vertex models ...

  • High-order hybridizable discontinuous Galerkin formulation for one-phase flow through porous media 

    Costa Solé, Albert; Ruiz Gironès, Eloi; Sarrate Ramos, Josep (2021-03-06)
    Article
    Restricted access - publisher's policy
    We present a stable high-order hybridizable discontinuous Galerkin (HDG) formulation coupled with high-order diagonal implicit Runge–Kuta (DIRK) schemes to simulate slightly compressible one-phase flow through porous media. ...

  • Pilot3 - D1.1 Technical Resources and Problem definition 

    Delgado Muñoz, Luis; Kuljanin, Jovana; Villardi de Montlaur, Adeline de; Prats Menéndez, Xavier; Martínez, Darío; Fernández, Antonio; Schultz, Ralph (2020-05-11)
    External research report
    Open Access
    This deliverable starts with the proposal of Pilot3 but incorporates the development produced during the first four months of the project: activities on different workpackages, interaction with Topic Manager and Project ...

  • A combined reduced order-full order methodology for the solution of 3D magneto-mechanical problems with application to magnetic resonance imaging scanners 

    Seoane Chouciño, Marcos; Ledger, Paul D.; Gil, Antonio; Zlotnik, Sergio; Mallett, Mike (2020-01-01)
    Article
    Restricted access - publisher's policy
    The design of a new magnetic resonance imaging (MRI) scanner requires multiple numerical simulations of the same magneto-mechanical problem for varying model parameters, such as frequency and electric conductivity, in order ...

  • The 2020 motile active matter roadmap 

    Gompper, Gerhard; Winkler, Roland G.; Speck, Thomas; Solon, Alexandre; Nardini, Cesare; Peruani, Fernando; Löwen, Hartmut; Golestanian, Ramin; Kaupp, U. Benjamin; Arroyo Balaguer, Marino (Institute of Physics (IOP), 2020-05-08)
    Article
    Open Access
    Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of 'active matter' in recent years, which focuses on the physical aspects of propulsion mechanisms, and ...

  • A physical mechanism of TANGO1-mediated bulky cargo export 

    Raote, Ishier; Chabanon, Morgan; Walani, Nikhil; Arroyo Balaguer, Marino; Garcia Parajo, Maria; Malhotra, Vivek; Campelo Aubarell, Felix (2020-11-10)
    Article
    Open Access
    The endoplasmic reticulum (ER)-resident protein TANGO1 assembles into a ring around ER exit sites (ERES), and links procollagens in the ER lumen to COPII machinery, tethers, and ER-Golgi intermediate compartment (ERGIC) ...

  • Spontaneous polarization and locomotion of an active particle with surface-mobile enzymes 

    Corato, Marco de; Pagonabarraga Mora, Ignacio; Abdelmohsen, Loai K. E. A.; Sanchez Ordoñez, Samuel; Arroyo Balaguer, Marino (2020-12-17)
    Article
    Open Access
    We examine a mechanism of locomotion of active particles whose surface is uniformly coated with mobile enzymes. The enzymes catalyze a reaction that drives phoretic flows but their homogeneous distribution forbids locomotion ...

  • Topological features dictate the mechanics of the mammalian brains 

    Sáez Viñas, Pablo; Duñó Nosas, Carles; Sun, L. Y.; Antonovaite, Nelda; Malve, M.; Tost Pardell, Daniela; Goriely, Alain (2020-12-01)
    Article
    Restricted access - publisher's policy
    Understanding brain mechanics is crucial in the study of pathologies involving brain deformations such as tumor, strokes, or in traumatic brain injury. Apart from the intrinsic mechanical properties of the brain tissue, ...
