    Understanding and characterizing the mechanical and structural properties of brain tissue is essential for developing and calibrating reliable material models. Based on the Theory of Porous Media, a novel nonlinear ...
  • The role of computational models in mechanobiology of growing bone 

    Comellas Sanfeliu, Ester; Shefelbine, Sandra J. (Frontiers Media SA, 2022-11-18)
    Article
    Accés obert
    Endochondral ossification, the process by which long bones grow in length, is regulated by mechanical forces. Computational models, specifically finite element models, have been used for decades to understand the role of ...
  • I’m stuck! How to efficiently debug computational solid mechanics models so you can enjoy the beauty of simulations 

    Comellas Sanfeliu, Ester; Pelteret, Jean-Paul; Bangerth, Wolfgang (2023-01)
    Article
    Accés obert
    A substantial fraction of the time that computational modellers dedicate to developing their models is actually spent trouble-shooting and debugging their code. However, how this process unfolds is seldom spoken about, ...
  • Coiled phononic crystal with periodic rotational locking: subwavelength bragg band gaps 

    Willey, Carson L.; Chen, Vincent W.; Roca Cazorla, David; Kianfar, Armin; Hussein, Mahmoud I.; Juhl, Abigail T. (American Physical Society (APS), 2022-07-15)
    Article
    Accés obert
    Phononic crystals (PnC) are spatially periodic materials with band gaps that form by Bragg scattering of elastic waves. Within the frequency range of a band gap, wave propagation is not admitted. A long-standing limitation ...
  • Usability of deep learning pipelines for 3D nuclei identification with Stardist and Cellpose 

    Kleinberg, Giona; Wang, Sophia; Comellas Sanfeliu, Ester; Monaghan, James R.; Shefelbine, Sandra J. (Elsevier, 2022-12)
    Article
    Accés obert
    Segmentation of 3D images to identify cells and their molecular outputs can be difficult and tedious. Machine learning algorithms provide a promising alternative to manual analysis as emerging 3D image processing technology ...
  • 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
    Accés obert
    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 ...
  • Design of an intake and a thruster for an atmosphere-breathing electric propulsion system 

    Romano, Francesco; Herdrich, Georg; Chan, Yung-An; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2022-10)
    Article
    Accés obert
    Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that fnally defnes the mission’s lifetime, unless a way to compensate for it is ...
  • Development and analysis of novel mission scenarios based on Atmosphere-Breathing Electric Propulsion (ABEP) 

    Vaidya, Shreepali Sanjay; Traub, Constantin; Romano, Francesco; Rodríguez Donaire, Silvia; García-Almiñana, Daniel; Sureda Anfres, Miquel; García Berenguer, Marina (2022-10)
    Article
    Accés obert
    Operating satellites in Very Low Earth Orbit (VLEO) benefit the already expanding New Space industry in applications including Earth Observation and beyond. However, long-term operations at such low altitudes require ...
