Image-based change quantitation has been recognized as a promising tool for accurate assessment of tumor's early response to chemoprevention in cancer research. For example, various changes on breast density and vascularity in glandular tissue are the indicators of early response to treatment. Accurate extraction of glandular tissue from pre- and postcontrast magnetic resonance (MR) images requ...

The meshless local Petrov–Galerkin (MLPG) method with radial basis functions (RBFs), and the higher order shear and normal deformable plate theory (HOSNDPT) are used to analyze static infinitesimal deformations of thick laminated composite elastic plates under different boundary conditions. Two types of RBFs, namely, multiquadrics (MQ) and thin plate splines (TPS), are employed for constructing...

A new form of thr~-dimensioM1 crystals of the 50 S ribosomal subunits from Haiobacterium m~~mortui has been obtained at 19”C, using ~iyethyle~e glycol in the presence of 1.2-1.7 M KC1 in the crystall~tion mixture. The crystals diffract X-rays to 13 A and are stable in the synehrotron radiation beam for 4-8 h. Being aggregates of thin plates, the dimensions of only two unit cell edges, 147 x 181...

Suday, Sptem er 5, 2016 significantly increases the risk of postoperative vaginal stenosis. This paper proposes a simple technique for the reconstruction of thin septa, utilising two interdigitating Y-flaps. The authors also present their 7-year experience of utilising this technique. Custom made illustrations and serial intraoperative photographs will accompany the podium presentation in order...

An algorithm for selection of knot point locations for approximation of functions from large sets of scattered data by least squares Thin Plate Splines is given. The algorithm is based on the idea that each data point is equally important in defining the surface, which allows the knot selection process to be decoupled from the least squares. Properties of the algorithm are investigated, and exa...

Ridge curves are important features in human vision (see Koenderink, 1990, p.295). In this paper we apply a simple algebraic criterion of Porteous (1994) to the problem of nding ridge curves in machine vision. This work provides a simpler approach than other existing methods (see for example, Thirion and Gourdon, 1992, and Hosaka, 1992). To identify ridge curves in practice on surface data it i...

A hypothesis that large-scale fracture of sea ice plates in the Arctic could be caused by the release of energy of thermal bending moments due to major temperature changes is advanced and examined. Bending propagation of a through-the-thiclrness crack along the floating plate, with negligible inertial forces, is analyzed, asswning the moment field in the plate near the traveling crack front and...

Shape correspondence, which aims at accurately identifying corresponding landmarks from a given population of shape instances, is a very challenging step in constructing a statistical shape model such as the Point Distribution Model. Many shape correspondence methods are primarily focused on closedsurface shape correspondence. The authors of this chapter discuss the 3D Landmark Sliding method o...
