Child retroperitoneal malignant teratoma at the Mother and Child University Hospital Lagune of Cotonou:about a case

World Journal of Pediatric Surgery 2020年第1期3卷 28-30页

INTRODUCTION Retroperitoneal malignant teratoma is a rare congenital tumor,representing 1%-10%of retroperitoneal tumors in children.12 A pathological migration of primitive germ cells to the genital ridges can stop at various levels,which explains the localizations of these tumors.3 The diagnosis is done either prena-tally,or later in front of an abdominal mass.45 We reported a case treated in our department and reviewed the diagnostic and therapeutic aspects of its management.

Growth,Structural and Microhardness Studies on New Semiorganic Single Crystals of Calcium Para Nitrophenolate Dihydrate

引用

Journal of Materials Science & Technology 2007年第6期23卷 855-859页

作者： C.Vesta R.Uthrakumar C.Justin Raj A.Jonie Varjula J.Mary Linet S.jerome Das Department of Physics Loyola CollegeChennai-34India

Good quality crystals of calcium p-nitrophenolate （NPCa） were grown from saturated solution by slow evaporation method. The crystal structure analysis and the molecular arrangement of these crystals were determined using X-ray diffraction （XRD）. From Single crystal XRD studies, NPCa is found to be crystallized in the mon- oclinic system with a space group P21/n. The functional groups of the material were confirmed qualitatively by F-FIR （Fourier transform infrared spectroscopy） spectral analysis. Optical absorption studies reveal the absorption region and microhardness studies were carried out to confirm the mechanical behaviour of the crystals.

Addendum to: An Approach to Hierarchical Clustering via Level Surfaces and Convexity

引用

Intelligent Information Management 2010年第5期2卷 299-305页

作者： jerome Malitz Seth Malitz 不详

This article is an addendum to the 2001 paper [1] which investigated an approach to hierarchical clustering based on the level sets of a density function induced on data points in a d-dimensional feature space. We refer to this as the “level-sets approach” to hierarchical clustering. The density functions considered in [1] were those formed as the sum of identical radial basis functions centered at the data points, each radial basis function assumed to be continuous, monotone decreasing, convex on every ray, and rising to positive infinity at its center point. Such a framework can be investigated with respect to both the Euclidean (L2) and Manhattan (L1) metrics. The addendum here puts forth some observations and questions about the level-sets approach that go beyond those in [1]. In particular, we detail and ask the following questions. How does the level-sets approach compare with other related approaches? How is the resulting hierarchical clustering affected by the choice of radial basis function? What are the structural properties of a function formed as the sum of radial basis functions? Can the levels-sets approach be theoretically validated? Is there an efficient algorithm to implement the level-sets approach?
