The application of first-principles computational methods to the study of ferroelectric perovskites has greatly expanded our theoretical understanding of this important class of materials. These methods have most recently been applied to an increasingly wide range of ferroelectric materials, with special attention to their lattice dynamics, phase transitions, and dielectric and piezoelectric pr...

Ralph Freese Department of Mathematics University of Hawaii at Manoa Honolulu, Hawaii 96822 In this paper we look at some of the problems on free lattices and free modular lattices which are of an order theoretic nature. We review some of the known results, give same new results, and present several open problems. Every countable partially ordered set can be order embedded into a countable free...

The growth of Online Social Network ing (OSN) has encouraged new ways of communicating and sharing information and is used regularly by millions of people; it now seem s that OSN will be an enduring part of everyday life. The rapid growth of OSN has also resulted in an increase in its use for significant criminal activities and perpetrators are becoming increasingly sophisticated in their attem...

Die dynamische Situation, in der sich Unternehmen heutzutage befinden, fordert effiziente Entscheidungsprozesse. Dazu werden präzise und solide Analysen der Geschäftsdaten benötigt. Die fortlaufende Entwicklung und das Bestreben, immer mehr Daten zu erfassen, schafft riesige Datenmengen (Köster 2002). Dies zeigt sich ebenfalls im Personalwesen bzw. im Human Resource Management (HRM), wo eine Vi...

The Notch signaling pathway is an intercellular communication network vital to metazoan development. Notch activation leads to the nuclear localization of the intracellular portion (NICD) of the Notch receptor. Once in the nucleus, NICD binds the transcription factor CSL through a bivalent interaction involving the high-affinity RAM region and the lower affinity ANK domain, converting CSL from ...

We have identified ramshackle (ram) as a dominant suppressor of hedgehog loss-of-function in the developing Drosophila eye. We have characterized the gene and it encodes a double bromodomain protein with eight WD40 repeats. The Ram protein is localized predominantly to polytene chromosome interbands and is required for the transcription of some genes. ram is an essential gene and null mutants d...
