Modeling the deformable shape of the left atrium is of strong interest for many applications in cardiac diagnosis and intervention. In this paper, we propose a method for left atrium shape modeling using non-rigid point cloud registration. In particular, we build upon the concept of Coherent Point Drift (CPD) registration that considers the alignment as a probability density estimation problem....

in this study gill-net selectivity for alburnus chalcoides inhabiting the almus dam lake was estimated. experimental gill-net fishing was conducted using gill-net with 15 mm and 20 mm mesh-size, during october 2002 and september 2003. a total of 254 and 198 specimens of a. chalcoides were caught by gill-net with 15 mm and 198 with the 20 mm mesh-size, respectively. the total length of the fish ...

Realistic simulation and manipulation of virtual cloth based on energy minimization techniques require higher computations. A model realizing force as well as shape to manipulate the virtual cloth demands even more computational cost. Mesh resolution of cloth has a great effect on the computational cost of cloth simulation. Therefore, granularity of mesh must be chosen in a manner that represen...

purpose: to report the results of a wrapping technique for hydroxyapatite orbital implants by using mersilen mesh. methods: this study is prospective interventional case series conducted on records of 55 consecutive patients who received a mersilen mesh-wrapped ha orbital implant after enucleation or as a secondary procedure. we recorded results and potiential problem before and after pegging d...

background: teat lacerations are serious injuries thatendanger the survival of a cow within the herd. in excessivelacerations, the wound should be left to heal by second intentionhealing process. however, tissue contraction during healing canchange the alignment of the teat, creating problems for machinemilking. objectives: the purpose of the present study was toevaluate the transplantation of ...

Density Estimation is a very popular method to compute global illumination solutions in a complex virtual scene. After simulating the re ection paths of a large number of photons in the scene, the illumination at a surface point is approximated by estimating the density of photon hits in the point's surrounding. In this paper we describe a novel approach to compute such a density approximation ...

A mesh objective crack band model was implemented within the generalized method of cells micromechanics theory. This model was linked to a macroscale finite element model to predict post-peak strain softening in composite materials. Although a mesh objective theory was implemented at the microscale, it does not preclude pathological mesh dependence at the macroscale. To ensure mesh objectivity ...

Most blood vessels contain elastin that provides the vessels with the resilience and flexibility necessary to control hemodynamics. Pathophysiological hemodynamic changes affect the remodeling of elastic components, but little is known about their structural properties. The present study was designed to elucidate, in detail, the three-dimensional (3D) architecture of delicate elastic fibers in ...

The dynamic polymerization and depolymerization of actin filaments is essential for various cellular processes such as cell migration, rotation, cytokinesis, and mammalian oocyte maturation. Tropomodulin 3 (Tmod3) binds to the slow-growing (pointed) ends of the actin filament, thereby protecting the filament from depolymerization. However, the roles of Tmod3 in mammalian oocyte maturation remai...
