  • Using reduced basis approximation for efficient surrogate-based inverse identification of thermo-hydro-mechanical parameters from an in situ heating test 

    Larion, Ygee; Chen, Guangjing; Zlotnik, Sergio; Díez, Pedro; Seetharam, Suresh; Massart, Thierry J. (Springer Nature, 2022-06-27)
    Article
    Restricted access - publisher's policy
    In this paper, a reduced-order model built from the reduced basis (RB) method is used as a surrogate for an inverse identification problem related to coupled thermo-hydro-mechanical (THM) processes. The RB space—spanned ...

  • Local mechanical stimuli correlate with tissue growth in axolotl salamander joint morphogenesis 

    Comellas Sanfeliu, Ester; Farkas, Johanna E.; Kleinberg, Giona; Lloyd, Katlyn; Mueller, Thomas; Duerr, Timothy; Muñoz Romero, José; Monaghan, James R.; Shefelbine, Sandra J. (2022-05-25)
    Article
    Open Access
    Movement-induced forces are critical to correct joint formation, but it is unclear how cells sense and respond to these mechanical cues. To study the role of mechanical stimuli in the shaping of the joint, we combined ...

  • A multiparametric advection-diffusion reduced-order model for molecular transport in scaffolds for osteoinduction 

    Muixí Ballonga, Alba; Zlotnik, Sergio; Calvet Tordera, Pere; Español Pons, Montserrat; Lodoso Torrecilla, Irene; Ginebra Molins, Maria Pau; Díez, Pedro; García González, Alberto (Springer Nature, 2022-05-05)
    Article
    Open Access
    Scaffolds are microporous biocompatible structures that serve as material support for cells to proliferate, differentiate and form functional tissue. In particular, in the field of bone regeneration, insertion of scaffolds ...

  • Dynamic mechanochemical feedback between curved membranes and BAR protein self-organization 

    Le Roux, Anabel-Lise; Tozzi, Caterina; Walani, Nikhil; Quiroga Álvarez, Xarxa; Zalvidea, Dobryna; Trepat Guixer, Xavier; Staykova, M; Arroyo Balaguer, Marino; Roca-Cusachs, Pere (2021-11-12)
    Article
    Open Access
    In many physiological situations, BAR proteins reshape membranes with pre-existing curvature (templates), contributing to essential cellular processes. However, the mechanism and the biological implications of this reshaping ...

  • On the net displacement of contact surface centroid in contractile bodies 

    Muñoz Romero, José; Condamin, Lucie; Doste Poy, David (2022-01-01)
    Article
    Restricted access - publisher's policy
    We investigate the motion of the contact surface centroid for contractile bodies on substrates with a viscous friction law and when inertial forces are negligible. We deduce a set of sufficient conditions that ensure that ...

  • Phase distribution and properties identification of heterogeneous materials: a data-driven approach 

    Valdés Alonzo, Gabriel Rolando; Binetruy, Christophe; Eck, Benedikt; García González, Alberto; Leygue, Adrien (2022-02-15)
    Article
    Restricted access - publisher's policy
    This paper presents a new methodology to extend the Data-Driven Identification (DDI) to heterogeneous samples made of multiple elastic materials. By using the Correspondence Analysis (CA) technique to post-process DDI, we ...

  • Numerical modelling of opposing subduction in the Western Mediterranean 

    Peral Millán, Mireia; Fernandez Ortiga, Manel; Vergés Masip, Jaume; Zlotnik, Sergio; Jimenez Munt, Ivone (2022-05-05)
    Article
    Open Access
    The geodynamic evolution of the Western Mediterranean related to the closure of the Ligurian-Tethys ocean is not yet fully resolved. We present a new 3D numerical model of double subduction with opposite polarities fostered ...

  • Mathematical and computational modeling of flexoelectricity 

    Codony Gisbert, David; Mocci, Alice; Barceló Mercader, Jordi; Arias Vicente, Irene (2021-12-21)
    Article
    Open Access
    We first revisit the mathematical modeling of the flexoelectric effect in the context of continuum mechanics at infinitesimal deformations. We establish and clarify the relation between the different formulations, point ...

  • A nonintrusive reduced order method for the NVH assessment and automotive structural dynamics 

    Cavaliere, Fabiola; Zlotnik, Sergio; Sevilla Cárdenas, Rubén; Larráyoz Izcara, Xabier; Díez, Pedro (2021)
    Conference report
    Restricted access - publisher's policy
    The goal of this work is to develop a computational method able to optimize the design process of a car structure and provide a tool which can support designers during the decision-making phase. The design of a car ...

  • Differential equations 

    Zlotnik, Sergio; Soler Villanueva, Jaume (Springer, 2022)
    Part of book or chapter of book
    Restricted access - publisher's policy
    The Encyclopedia of Mathematical Geosciences is a complete and authoritative reference work. It provides concise explanation on each term that is related to Mathematical Geosciences. Over 300 international scientists, each ...

  • Inverting angiogenesis with interstitial flow and chemokine matrix-binding affinity 

    Moure, Adrian; Vilanova Caicoya, Guillermo; Gomez, Hector (Nature, 2022-05-10)
    Article
    Open Access
    The molecular signaling pathways that orchestrate angiogenesis have been widely studied, but the role of biophysical cues has received less attention. Interstitial flow is unavoidable in vivo, and has been shown to ...

  • A new Updated Reference Lagrangian Smooth Particle Hydrodynamics algorithm for isothermal elasticity and elasto-plasticity 

    Refachinho de Campos, Paulo Roberto; Antonio Javier, Gil; Chun Hean, Lee; Giacomini, Matteo; Bonet Carbonell, Javier (2022-03-15)
    Article
    Open Access
    This paper presents a new Updated Reference Lagrangian Smooth Particle Hydrodynamics (SPH) algorithm for the analysis of large deformation isothermal elasticity and elasto-plasticity. Taking as point of departure a Total ...
