  • Swimming Euglena respond to confinement with a behavioural change enabling effective crawling 

    Noselli, Giovanni; Beran, Alfred; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02-18)
    Article
    Open Access
    Some euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for centuries. Yet, its function remains ...
  • Modelling fluid deformable surfaces with an emphasis on biological interfaces 

    Torres Sánchez, Alejandro; Millán, Daniel; Arroyo Balaguer, Marino (2019-08-10)
    Article
    Restricted access - publisher's policy
    Fluid deformable surfaces are ubiquitous in cell and tissue biology, including lipid bilayers, the actomyosin cortex or epithelial cell sheets. These interfaces exhibit a complex interplay between elasticity, low Reynolds ...
  • Automatically imposing incremental boundary displacements for valid mesh morphing and curving 

    Ruiz Gironès, Eloi; Gargallo Peiró, Abel; Sarrate Ramos, Josep; Roca, Xevi (2019-07)
    Article
    Open Access
    We present a new incremental mesh morphing method obtained by proposing and discretizing a solution procedure for the continuous morphing problem. Our method seeks a diffeomorphism that transforms an initial domain to a ...
  • An HDG formulation for incompressible and immiscible two-phase porous media flow problems 

    Costa Solé, Albert; Ruiz Gironès, Eloi; Sarrate Ramos, Josep (Taylor & Francis, 2019-05-27)
    Article
    Restricted access - publisher's policy
    We develop a high-order hybridisable discontinuous Galerkin (HDG) formulation to solve the immiscible and incompressible two-phase flow problem in a heterogeneous porous media. The HDG method is locally conservative, has ...
  • Tensor representation of non-linear models using cross approximations 

    Aguado, José Vicente; Borzacchiello, Domenico; Kollepara, Kiran Sagar; Chinesta Soria, Francisco; Huerta, Antonio (2019-02-19)
    Article
    Restricted access - publisher's policy
    Tensor representations allow compact storage and efficient manipulation of multi-dimensional data. Based on these, tensor methods build low-rank subspaces for the solution of multi-dimensional and multi-parametric models. ...
  • A hybridizable discontinuous Galerkin phase-field model for brittle fracture 

    Muixí Ballonga, Alba; Fernández Méndez, Sonia; Rodríguez Ferran, Antonio (2019-05-01)
    Article
    Open Access
    Phase-field models for brittle fracture consider smeared representations of cracks, which are described by a continuous field that varies abruptly in the transition zone between unbroken and broken states. Computationally, ...
  • Structural health monitoring by combining machine learning and dimensionality reduction techniques 

    Quaranta, Giacomo; López Tomás, Elena; Abisset-Chavanne, Emmanuelle; Duval, Jean Louis; Huerta, Antonio; Chinesta Soria, Francisco (2019-01-01)
    Article
    Open Access
    Structural Health Monitoring is of major interest in many areas of structural mechanics. This paper presents a new approach based on the combination of dimensionality reduction and data-mining techniques able to differentiate ...
  • Comparison of high-order continuous and hybridizable discontinuous {G}alerkin methods in incompressible fluid flow problems 

    Paipuri, Mahendra; Fernández Méndez, Sonia; Tiago, Carlos (2018-10-01)
    Article
    Open Access
    The computational efficiency and the stability of Continuous Galerkin (CG) methods, with Taylor–Hood approximations, and Hybridizable Discontinuous Galerkin (HDG) methods are compared for the solution of the incompressible ...
  • Smart helical structures inspired by the pellicle of euglenids 

    Noselli, Giovanni; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02)
    Article
    Restricted access - publisher's policy
    This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative sliding of adjacent strips. Uniform sliding ...
  • Fully coupled numerical model of actin treadmilling in the lamellipodium of the cell 

    Kollepara, Kiran Sagar; Mulye, Paris D.; Sáez Viñas, Pablo (John Wiley & sons, 2018-12)
    Article
    Restricted access - publisher's policy
    Cells rely on an interplay of subcellular elements for motility and migration. Certain regions of motile cells, such as the lamellipodium, are made of a complex mixture of actin monomers and filaments, which polymerize at ...
  • A multidimensional data-driven sparse identification technique: the sparse proper generalized decomposition 

    Ibáñez Pinillo, Rubén; Abisset Chavanne, Emmanuelle; Ammar, Amine; González Ibáñez, David; Cueto Prendes, Elias; Huerta, Antonio; Duval, Jean Louis; Chinesta Soria, Francisco (2018-01-01)
    Article
    Open Access
    Sparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional ...
  • Mechanical oscillations in biological tissues as a result of delayed rest-length changes 

    Muñoz Romero, José; Dingle, Monica; Wenzel, Manuel (American Institute of Physics (AIP), 2018-11-26)
    Article
    Open Access
    Oscillatory behavior in tissue biology is ubiquitous and may be observed in the form of either chemical or mechanical signals. We present here and solve a mechanical cell model that exhibits oscillations emerging from ...
