Four complex intermetallic compounds BaAu6±xGa6±y (x = 1, y = 0.9) (I), BaAu6±xAl6±y (x = 0.9, y = 0.6) (II), EuAu6.2Ga5.8 (III), and EuAu6.1Al5.9 (IV) have been synthesized, and their structures and homogeneity ranges have been determined by single crystal and powder X-ray diffraction. Whereas I and II originate from the NaZn13-type structure (cF104–112, Fm3̅c), III (tP52, P4/nbm) is derived fr...

Identification of thyroid hormone receptor (TR) co-regulators has enhanced our understanding of thyroid hormone (TH) action. However, it is likely that many other co-regulators remained unidentified, and unbiased methods are required to discover these proteins. We have previously demonstrated that the yeast Saccharomyces cerevisiae is an excellent system in which to study TR action, and that de...

With a high probablilty our randomized augmentation of a matrix eliminates its rank deficiency and ill conditioning. Our techniques avoid various drawbacks of the customary algorithms based on pivoting and orthogonalization, e.g., we readily preserve matrix structure and sparseness. Furthermore our randomized augmentation is expected to precondition quite a general class of ill conditioned inpu...

Purpose: This study aimed to analyze the fracture resistance of denture base resins relined with either a conventional rigid resin or a new resilient resin. Materials and Methods: Two types of test plates were fabricated by relining the base resin (Acron) with a conventional rigid resin (Tokuso Rebase, TR) or a newly developed relining resin (Tokuyama Rebase II, RII). The specimens were divided...

Matrices with the structures of Toeplitz, Hankel, Vandermonde and Cauchy types are omnipresent in modern computations in Sciences, Engineering and Signal and Image Processing. The four matrix classes have distinct features, but in [P90] we showed that Vandermonde and Hankel multipliers transform all these structures into each other and proposed to employ this property in order to extend any suc...

The effect of different statuses of honeybee queens, Apis mellifera (one-year-old mated queen; supersedure queen; three-day old virgin queen; queen cell; without queen; and without queen/without bee bread) on many aspects of 3day old workers were studied with scanning electron microscopy (SEM). This study was carried out to describe the (types, distribution, numbers and measurements) of the dif...

OBJECTIVE To determine sensitivity and specificity of a standardized recombinant cell-based indirect immunofluorescence assay (RC-IFA) for anti-Tr antibodies in comparison to a reference procedure. METHODS Delta/Notch-like epidermal growth factor-related receptor (DNER) was expressed in HEK293 and used as a substrate for RC-IFA. HEK293 control cells expressing CDR2/Yo and CDR2L as well as moc...

Public sector applications e.g. the process of application of a biometric visa are connected to different kinds of technical, organisational, and legal requirements. But how can those requirements and recommendations be retrieved, analysed and described? The German federal government has taken part in the European pilot project BioDEV II in order to gain comprehensive experiences regarding the ...
