Seventy-six vital permanent incisors with complicated crown t’ractures in 72 children were assessed clinically and radiographically for the healing of pulp exposures treated by direct pulp capping or by pulpotomy. Thirty-eight of these teeth had pinpoint exposures, complete roots, and were treated by pulp capping. Pulpotomy was the treatment for the other 38 teeth that had incomplete root devel...

We present an algorithm for completing a C surface of up to degree bi-6 by capping an n-sided hole with polar layout. The cap consists of n tensor-product patches, each of degree 6 in the periodic and degree 5 in the radial direction. To match the polar layout, one edge of these patches is collapsed. We explore and compare with alternative constructions, based on more pieces or using total-degr...

This article addresses the problem of identification of partly destroyed human melanoma cancer cells in confocal microscopy imaging. Complete cancer cells are nearly circular and most of them have a nearly homogeneous boundary and interior region. A deformable template (Grenander, 1993) is well suited for these complete cells and models a cell as a natural deformed template or prototype. We wil...

In epitaxial polar-oxide interfaces, conductivity sets in beyond a finite number of monolayers (ML). This threshold for is explained by accumulating sufficient electric potential to initiate charge transfer the interface. Here we experimentally and theoretically study ${\mathrm{LaAlO}}_{3}/{\mathrm{SrTiO}}_{3}$ (111) interface where critical thickness ${t}_{c}$ nine ${\mathrm{LaAlO}}_{3}$ ML re...

The effect of concanavalin A (Con A) on the capping of mouse lymphocyte surface immunoglobulin (surface Ig), cross-linked by rabbit anti-mouse Ig antibody, and on the capping of mouse thymocyte theta antigen, cross-linked by anti-theta alloantibody and rabbit anti-mouse Ig antibody, has been studied by immunofluorescence, using fluorescein conjugated Con A and rhodamine-conjugated anti-mouse Ig...

When mouse B lymphocytes are incubated with antibodies against their surface immunoglobulin (Ig), patching and capping occur in a process that involves the action of the actomyosin cytoskeleton and the mobilization of cell calcium. Calmodulin (CAM) plays a central role in the Ca ++ regulation of many cellular structures and processes, including the cytoskeleton and membrane-bound enzymes, and t...

that form in G-rich tracts of the genome affect chromosomal stability and processes such as copying the genetic information (DNA replication) or decoding the information (RNA transcription) has posed a significant challenge to researchers in the field. Although historically there has been some controversy over the existence of G4 DNA structures in vivo, emerging evidence suggests that they are ...
