Uniformly stable mixedhp-finite elements on multilevel adaptive grids with hanging nodes [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2008 Summary: We consider a family of quadrilateral or hexahedral mixed \(hp\)-finite elements for an incompressible flow problem with \(Q_r\)-elements for velocity and discontinuous \(P_{r-1}\)-elements for pressure, where the order \(r\) can vary from element to element between 2 and an arbitrary bound. For multilevel adaptive grids with hanging nodes and

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations
Advanced Materials Interfaces, EarlyView.This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Phase-field modeling of brittle fracture with multi-level hp-FEM and the finite cell method
, 2018 The difficulties in dealing with discontinuities related to a sharp crack are overcome in the phase-field approach for fracture by modeling the crack as a diffusive object being described by a continuous field having high gradients.

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

PhysiCell: An open source physics-based cell simulator for 3-D multicellular systems.
PLoS Computational Biology, 2018 Many multicellular systems problems can only be understood by studying how cells move, grow, divide, interact, and die. Tissue-scale dynamics emerge from systems of many interacting cells as they respond to and influence their microenvironment. The ideal

A tetrahedral space-filling curve for non-conforming adaptive meshes
, 2016 We introduce a space-filling curve for triangular and tetrahedral red-refinement that can be computed using bitwise interleaving operations similar to the well-known Z-order or Morton curve for cubical meshes.

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
Advanced Science, EarlyView.We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...
