Diagramme sind ein anschauliches Mittel zur Beschreibung komplexer Zusammenhange. Besonders im Bereich der visuellen Sprachen und Programmierumgebungen sind Diagrammeditoren mit automatischer Layoutanpassung f ur die interaktive Erstellung von Diagrammen w unschenswert. Zur weitgehend automatischen Generierung solcher Diagrammeditoren ist eine formale Grundlage der Diagrammbeschreibung notwe...

We give an explicit formula for the correspondence between simple Yetter-Drinfeld modules for certain finite-dimensional pointed Hopf algebras H and those for cocycle twists H of H. This implies an equivalence between modules for their Drinfeld doubles. To illustrate our results, we consider the restricted two-parameter quantum groups ur,s(sln) under conditions on the parameters guaranteeing th...

The present study was on the phytoassessment of a waste engine oil (WEO)-polluted soil after amendment, using Vigna unguiculata cv. Ife Brown. Top (0 - 10 cm) constant measured into buckets. WEO poured and thoroughly mixed to obtain 2.5% w/w oil-in-soil concentration. Polluted soils were with manure (MN) and/or sawdust (SD) at 10% respectively. However, when more than amendment applied, they bo...

The effects of uridine(UR) on the cell-killing activity of cytosine arabinoside(ara-C) against human leukemic cells, MOLT-4, and on ara-C accumulation in cells were studied. The 50% lethal dose(LD50) of ara-C as determined by clonogenic assay was decreased to 5.0 x 10(-8) mol from 9.0 x 10(-7) mol after 3 days exposure to 10(-3) mol of UR. The accumulation of 3H-ara-C at 24 and 48 h was signifi...

The Lie algebra su(2) of the classical group SU(2) is built from two commuting quon algebras for which the deformation parameter is a common root of unity. This construction leads to (i) a not very well-known polar decomposition of the generators J− and J+ of the SU(2) group, with J+ = J † − = HUr where H is Hermitean and Ur unitary, and (ii) an alternative to the {J2, Jz} quantization scheme, ...

BACKGROUND The Risk Evaluation and Mitigation Strategy (REMS) for retigabine/ezogabine (RTG/EZG) required an evaluation of the effectiveness of the communication plan to communicate about the risks with use of RTG/EZG. OBJECTIVE GlaxoSmithKline conducted a survey to assess understanding of the risk of urinary retention (UR) with RTG/EZG and to evaluate the effectiveness of the communication p...

After beginning with a short historical review of the concept of displaced (coherent) and squeezed states, we discuss previous (often forgotten) work on displaced and squeezed number states. Next, we obtain the most general displaced and squeezed number states. We do this in both the functional and operator (Fock) formalisms, thereby demonstrating the necessary equivalence. We then obtain the t...
