This paper presents a method for effectively modeling the outer surfaces of inlay/onlay prostheses restoring teeth that are partially destroyed. We exploit 3D mesh deformation techniques: direct manipulation free-form deformation (DMFFD) [9] and multiple wires deformation (MWD) [10] with three kinds of information: standard teeth models, scanned mesh data from the plaster cast of a patient's to...

conclusions our results support the use of pns in some patients with refractory chronic headaches. appropriate surgical planning and technique are important to achieve good clinical outcome and to minimize complications. background subcutaneous peripheral nerve stimulation (pns) has emerged as a useful tool in the treatment of intractable headaches. however, complications such as skin erosion, ...

background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb.   methods: ...

Immunoglobulin-positive lymphocytes are present close to vasoactive intestinal polypeptide-positive (VIP(+)) nerve fibers in the lamina propria of the intestinal tract, and have an important role in mucosal defense. The number of immunoglobulin A-positive (IgA(+)) cells close to the epithelial basement membrane and nerve fibers is increased by the administration of lipopolysaccharides, which in...

Glaucoma causes variations of the optic nerve head (ONH). We propose an approach to describe the inter subject variability of the ONH by dense deformation fields produced by non-rigid registration. Non-glaucoma but acquisition related variations are eliminated in a preprocessing step. Standard non-rigid registration was extended by a radial smoothing regularizer to preserve the ONH natural circ...

In this paper we represent the Vassiliev model for the homotopy type of the one-point compactification of subspace arrangements as a homotopy colimit of an appropriate diagram over the nerve complex of the intersection semilattice of the arrangement. Furthermore, using a generalization of simplicial collapses to diagrams of topological spaces over simplicial complexes, we construct an explicit ...
