    • Cell-based maximum entropy approximants 

      Millán, Raúl Daniel; Sukumar, N; Arroyo Balaguer, Marino (2015-02-01)
      Article
      Accés obert
      In this paper, we devise cell-based maximum-entropy (max-ent) basis functions that are used in a Galerkin method for the solution of partial differential equations. The motivation behind this work is the construction of ...
    • Cell-centred model for the simulation of curved cellular monolayers 

      Mosaffa, Payman; Asadipour, Nina; Millán, Raúl Daniel; Rodríguez Ferran, Antonio; Muñoz Romero, José (2015)
      Article
      Accés obert
      This paper presents a cell-centred model for the simulation of planar and curved multicellular soft tissues. We propose a computational model that includes stress relaxation due to cell reorganisation (intercellular ...
    • Charting molecular free-energy landscapes with an atlas of collective variables 

      Hashemian, B.; Millán, Raúl Daniel; Arroyo Balaguer, Marino (2016-11-07)
      Article
      Accés obert
      Collective variables (CVs) are a fundamental tool to understand molecular flexibility, to compute free energy landscapes, and to enhance sampling in molecular dynamics simulations. However, identifying suitable CVs is ...
    • Modeling and enhanced sampling of molecular systems with smooth and nonlinear data-driven collective variables 

      Hashemian, B.; Millán, Raúl Daniel; Arroyo Balaguer, Marino (2013)
      Article
      Accés obert
      Collective variables (CVs) are low-dimensional representations of the state of a complex system, which help us rationalize molecular conformations and sample free energy landscapes with molecular dynamics simulations. Given ...
    • Nonlinear manifold learning for meshfree finite deformation thin shell analysis 

      Millán, Raúl Daniel; Arroyo Balaguer, Marino; Rosolen, Adrián (John Wiley & Sons, 2013-02)
      Article
      Accés obert
      Calculations on general point-set surfaces are attractive because of their flexibility and simplicity in the preprocessing but present important challenges. The absence of a mesh makes it nontrivial to decide if two ...
    • Numerical integration by using local-node gauss-hermite cubature 

      Millán, Raúl Daniel; Rosolen, Adrián Martín; Arroyo Balaguer, Marino (2009-06-08T10:53:59Z)
      Text en actes de congrés
      Accés obert
      A local–node numerical integration scheme for meshless methods is presented in this work. The distinguishing characteristic of the introduced scheme is that not support mesh or grid to perform numerical integration is ...
    • Reverse engineering the euglenoid movement 

      Arroyo Balaguer, Marino; Heltai, Luca; Millán, Raúl Daniel; DeSimone, Antonio (2012-10)
      Article
      Accés obert
      Euglenids exhibit an unconventional motility strategy amongst unicellular eukaryotes, consisting of large-amplitude highly concerted deformations of the entire body (euglenoid movement or metaboly). A plastic cell envelope ...
    • Second order convex maximum entropy approximants with applications to high order PDE 

      Rosolen, Adrian Martin; Millán, Raúl Daniel; Arroyo Balaguer, Marino (2013-04-13)
      Article
      Accés obert
      We present a new approach for second order maximum entropy (max-ent) meshfree approximants that produces positive and smooth basis functions of uniform aspect ratio even for non-uniform node sets, and prescribes robustly ...
    • Solmec: an efficient c++ library to solve linear and nonlinear elasticity problems 

      Rosolen, Adrián Martín; Millán, Raúl Daniel; Arroyo Balaguer, Marino (2009-06-02T09:11:26Z)
      Text en actes de congrés
      Accés obert
      A C++ library based on local maximum-entropy approximation schemes to solve linear and nonlinear elasticity problem is presented. The available tools are briefly described, and several implementation details are also ...
    • Thin shell analysis from scattered points with maximum-entropy approximants 

      Millán, Raúl Daniel; Rosolen, Adrián; Arroyo Balaguer, Marino (John Wiley & Sons, 2011-02)
      Article
      Accés obert
      We present a method to process embedded smooth manifolds using sets of points alone. This method avoids any global parameterization and hence is applicable to surfaces of any genus. It combines three ingredients: (1) the ...
