We study the presence of low intensity high velocity components, which we have termed wing features in the integrated Hα emission line profiles of the H  region populations of the spiral barred galaxies NGC 1530, NGC 3359 and NGC 6951. We find that more than a third of the H  region line profiles in each galaxy show these components. The highest fraction is obtained in the galaxy whose line...

AIM To present a case of expansive focal cemento-osseous dysplasia and emphasize the importance of differential diagnosis. BACKGROUND Cemento-osseous dysplasia is categorized into three subtypes on the basis of the clinical and radiographic features: Periapical, focal and florid. The focal type exhibits a single site of involvement in any tooth-bearing or edentulous area of the jaws. These le...

The Ruelle operator theorem has been studied extensively both in dynamical systems and iterated function systems. In this paper we study the Ruelle operator theorem for non-expansive systems. Our theorems give some sufficient conditions for the Ruelle operator theorem to be held for a non-expansive system.

Background: CaBP7 is an EF-hand-containing transmembrane protein that inhibits PI4KIII activity. Results: PI4KIII interacts with CaBP7 NTD, which exhibits an expansive hydrophobic pocket. Conclusion: The structure of CaBP7 NTD is similar to that of CaM NTD but has a more expansive hydrophobic pocket containing fewer methionine residues. Significance: Regulation of PI4P synthesis is essential fo...

This paper gives an algebraic characterization of expansive actions of countable abelian groups on compact abelian groups. This naturally extends the classification of expansive algebraic Zd-actions given by Schmidt using complex varieties. Also included is an application to a natural class of examples arising from unit subgroups of integral domains. 2000 Mathematics Subject Classification: 22D...
