    • A variational model of fracture for tearing brittle thin sheets 

      Li, Bin; Millán Zurita, Daniel; Torres Sánchez, Alejandro; Arroyo Balaguer, Marino (2018-10)
      Article
      Accés obert
      Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics. In addition to its intrinsic and practical interest, ...
    • An integrative approach for modeling and simulation of heterocyst pattern formation in cyanobacteria filaments 

      Torres Sánchez, Alejandro; Gomez Gardenes, Jesus; Falo, Fernando (2015-03-01)
      Article
      Accés obert
      Heterocyst differentiation in cyanobacteria filaments is one of the simplest examples of cellular differentiation and pattern formation in multicellular organisms. Despite of the many experimental studies addressing the ...
    • Approximation of tensor fields on surfaces of arbitrary topology based on local Monge parametrizations 

      Torres Sánchez, Alejandro; Santos Oliván, Daniel; Arroyo Balaguer, Marino (2020-03-15)
      Article
      Accés obert
      We introduce a new method, the Local Monge Parametrizations (LMP) method, to approximate tensor fields on general surfaces given by a collection of local parametrizations, e.g. as in finite element or NURBS surface ...
    • Combined molecular/continuum modeling reveals the role of friction during fast unfolding of coiled-coil proteins 

      Torres Sánchez, Alejandro; Vanegas, Juan Manuel; Purohit, Prashant K.; Arroyo Balaguer, Marino (2019-05-30)
      Article
      Accés obert
      Coiled-coils are filamentous proteins that form the basic building block of important force-bearing cellular elements, such as intermediate filaments and myosin motors. In addition to their biological importance, coiled-coil ...
    • Examining the mechanical equilibrium of microscopic stresses in molecular simulations 

      Torres Sánchez, Alejandro; Vanegas, Juan Manuel; Arroyo Balaguer, Marino (2015-06-23)
      Article
      Accés restringit per política de l'editorial
      The microscopic stress field provides a unique connection between atomistic simulations and mechanics at the nanoscale. However, its definition remains ambiguous. Rather than a mere theoretical preoccupation, we show that ...
    • Geometric derivation of the microscopic stress: a covariant central force decomposition 

      Torres Sánchez, Alejandro; Vanegas, Juan Manuel; Arroyo Balaguer, Marino (2016-08)
      Article
      Accés obert
      We revisit the derivation of the microscopic stress, linking the statistical mechanics of particle systems and continuum mechanics. The starting point in our geometric derivation is the Doyle-Ericksen formula, which states ...
    • hiperlife 

      Santos Oliván, Daniel; Torres Sánchez, Alejandro; Vilanova Caicoya, Guillermo; Bayat, Mohammad Reza; Font i Reverter, Jordi; Mirza, Waleed Ahmad; Arroyo Balaguer, Marino (Universitat Politècnica de Catalunya, 2021-06-17)

    • Importance of force decomposition for local stress calculations in biomembrane molecular simulations 

      Vanegas, Juan Manuel; Torres Sánchez, Alejandro; Arroyo Balaguer, Marino (2014-02-01)
      Article
      Accés obert
      Local stress fields are routinely computed from molecular dynamics trajectories to understand the structure and mechanical properties of lipid bilayers. These calculations can be systematically understood with the ...
    • Mapping mechanical stress in curved epithelia of designed size and shape 

      Marín Llauradó, Ariadna; Kale, Sohan; Ouzeri, Adam Amine; Golde, Tom; Sunyer Borrell, Raimon; Torres Sánchez, Alejandro; Latorre Ibars, Ernest; Gómez González, Manuel; Roca Cusachs, Pere; Arroyo Balaguer, Marino; Trepat Guixer, Xavier (2023-07-07)
      Article
      Accés obert
      The function of organs such as lungs, kidneys and mammary glands relies on the three-dimensional geometry of their epithelium. To adopt shapes such as spheres, tubes and ellipsoids, epithelia generate mechanical stresses ...
    • Modelling fluid deformable surfaces with an emphasis on biological interfaces 

      Torres Sánchez, Alejandro; Millán, Daniel; Arroyo Balaguer, Marino (2019-08-10)
      Article
      Accés obert
      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 ...
    • Onsager’s variational principle in soft matter : introduction and application to the dynamics of adsorption of proteins onto fluid membranes 

      Arroyo Balaguer, Marino; Walani, Nikhil; Torres Sánchez, Alejandro; Kaurin, Dimitri Jean Antoine (Springer, 2018)
      Capítol de llibre

      Article
      Accés obert
      Hydraulic fracturing plays a major role in cavity formation during embryonic development, when pressurized fluid opens microlumens at cell-cell contacts, which evolve to form a single large lumen. However, the fundamental ...
