Neuroscience is increasingly focusing on developmental factors related to human structural and functional connectivity. Unfortunately, to date, diffusion-based imaging approaches have only contributed modestly to these broad objectives, despite the promise of diffusion-based tractography. Here, we report a novel data-driven approach to detect similarities and differences among white matter trac...

in this study, flow characteristics through symmetric stenosis artery are investigated. the shape of eccentricity for stenotic flows is limited by circular-cross sections and plaques are usually assumed as to be oriented concentrically. thegoverningequationsaretheusualnavier-stokesequationsandare numericallysolved by using finite volumemethod in arbitrary orthogonal curvilinear coordinates. in ad...

Issues related to curvilinear mesh generation starting from a CAD model are addressed. Curvilinear mesh geometry representation in the context of p-version finite elements and its impact on the validity of curvilinear meshes is discussed. A set of meshing tools is described for generation and modification of curved meshes in three-dimensional space. An iterative algorithm for curved meshing of ...

We propose a novel tree-like curvilinear structure reconstruction algorithm based on supervised learning and graph theory. In this work we analyze image patches to obtain the local major orientations and the rankings that correspond to the curvilinear structure. To extract local curvilinear features, we compute oriented gradient information using steerable filters. We then employ Structured Sup...

OBJECTIVE To evaluate the effectiveness of various surgical procedures in the management of posterior capsule and anterior vitreous on the prevention of visual axis opacification. SUBJECTS, MATERIAL AND METHODS We retrospectively reviewed 120 eyes operated for unilateral congenital cataracts, with a median age at the time of cataract surgery of 21 months (interquartile range, 6-52 months). Th...
