    Distal radius malunion is a common and debilitating disorder. In this paper, a finite element model was used to study the influence of distal radius orientation on distal radioulnar joint mechanics. Joint contact was most sensitive to dorsal rotation and anteversion of the distal radius. In most cases, more than 6° rotation would necessitate adaptation to maintain articular contact. This study represents an important step towards properly understanding distal radius malunion, as it relates to distal radioulnar joint mechanics.

    A variational level set-based technique for full-automated liver segmentation is proposed in this study. Efficiency of the proposed method in terms of accuracy (97%) and processing time has been provided by automated initialization of active contours, using an adaptive signed pressure force function and Sobolev gradient. Experimental results show that the proposed full-automated segmentation approach avoids local minima and stops evolution of the active contour at desired liver boundaries even if there is a cyst in the liver.

    The increasing complexity of vessel networks for 1D blood flow models, motivated by anatomical detail or automatic network generation, for example, poses the need for extremely efficient numerical solvers. As a possible answer to this requirement, we present a high-order, finite volume-type algorithm featuring local time stepping (LTS). The scheme is applied to simple and anatomically detailed one-dimensional arterial networks. Simulation time speed-ups of the LTS scheme with respect to the conventionally used global time-stepping strategy are extremely significant.
