  • Collective cell durotaxis emerges from long-range intercellular force transmission 

    Sunyer, Raimon; Conte, Vito; Escribano, Jorge; Elosegui Artola, Alberto; Labernadie, Anna; Valon, Leo; Navajas Navarro, Daniel; Garcia Aznar, José Manuel; Muñoz Romero, José; Trepat, Xavier (2016-09-09)
    Article

    The ability of cells to follow gradients of extracellular matrix stiffness—durotaxis—has been implicated in development, fibrosis, and cancer. Here, we found multicellular clusters that exhibited durotaxis even if isolated ...
  • Fourth order phase-field model for local max-ent approximants applied to crack propagation 

    Amiri, Fatemeh; Millán, Daniel; Arroyo Balaguer, Marino; Silani, Mohammad; Rabczuk, Timon (2016-12)
    Article
    Accés restringit per política de l'editorial
    We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ...
  • Computational modeling of acute myocardial infarction 

    Sáez Viñas, Pablo; Kuhl, E. (Gordon and Breach Science Publishers, 2016-07)
    Article
    Accés restringit per política de l'editorial
    Myocardial infarction, commonly known as heart attack, is caused by reduced blood supply and damages the heart muscle because of a lack of oxygen. Myocardial infarction initiates a cascade of biochemical and mechanical ...
  • Elliptic harbor wave model with perfectly matched layer and exterior bathymetry effects 

    Modesto Galende, David; Fernandez Mendez, Sonia; Huerta, Antonio (2016-09)
    Article
    Accés obert
    Standard strategies for dealing with the Sommerfeld condition in elliptic mild-slope models require strong assumptions on the wave field in the region exterior to the computational domain. More precisely, constant bathymetry ...
  • A new equilibrated residual method improving accuracy and efficiency of flux-free error estimates 

    Parés Mariné, Núria; Díez, Pedro (2017-01-01)
    Article
    Accés obert
    This paper presents a new methodology to compute guaranteed upper bounds for the energy norm of the error in the context of linear finite element approximations of the reaction–diffusion equation. The new approach revisits ...
  • A distortion measure to validate and generate curved high-order meshes on CAD surfaces with independence of parameterization 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (John Wiley & Sons, 2016-06)
    Article
    Accés restringit per política de l'editorial
    A framework to validate and generate curved nodal high-order meshes on Computer-Aided Design (CAD) surfaces is presented. The proposed framework is of major interest to generate meshes suitable for thin-shell and 3D finite ...
  • A Lagrangian–Eulerian finite element algorithm for advection–diffusion–reaction problems with phase change 

    Oliveira, Beñat; Afonso, Juan Carlos; Zlotnik, Sergio (2016-03)
    Article
    Accés restringit per política de l'editorial
    This paper presents a particle-based Lagrangian–Eulerian algorithm for the solution of the unsteady advection–diffusion–reaction heat transfer equation with phase change. The algorithm combines a Lagrangian formulation for ...
  • Proper generalized decomposition solution of the parameterized Helmholtz problem: application to inverse geophysical problems 

    Signorini, Marianna; Zlotnik, Sergio; Díez, Pedro (2017-02)
    Article
    Accés restringit per política de l'editorial
    The identification of the geological structure from seismic data is formulated as an inverse problem. The properties and the shape of the rock formations in the subsoil are described by material and geometric parameters, ...
  • Unified formulation of a family of iterative solvers for power systems analysis 

    Borzacchiello, Domenico; Chinesta, Francisco; Malik, Muhammad H.; García Blanco, Raquel; Díez, Pedro (2016-11)
    Article
    Accés restringit per política de l'editorial
    This paper illustrates the construction of a new class of iterative solvers for power flow calculations based on the method of Alternating Search Directions. This method is fit to the particular algebraic structure of the ...
  • Sticking and sliding of lipid bilayers on deformable substrates 

    Stubbington, L; Arroyo Balaguer, Marino; Staykova, M (2017-01)
    Article
    Accés obert
    We examine here the properties of lipid bilayers coupled to deformable substrates. We show that by changing the extent of the substrate hydrophilicity, we can control the membrane–substrate coupling and the response of the ...
