Six NAT2 single-nucleotide polymorphisms (SNPs) were analysed in 105 unrelated Ngawbe and 136 unrelated Embera Amerindians (482 chromosomes) by SNP-specific polymerase chain reaction analysis. 282C>T was the most common synonymous mutation, while 857G>A was the most frequent nonsynonymous inactivating exchange. The allelic frequency of the NAT2*5 series(More)
The diiraction analysis of dielectric gratings using a discretization technique for the approximation of the grating surface and the application of the Coupled{Wave Theory lead to the solution of an innnite system of ordinary diierential equations. As in general this system can solely be solved by numerical methods, its reduction to a nite dimensional(More)
A veriication of calculated electrical parameters of transmission lines on printed circuit boards is presented. Furthermore, the innuence of common manufacturing processes on the principle cross section of transmission lines and the resulting electrical parameters is subject of the investigations. With regard to existing manufacturing tolerances a(More)
A new-generation interconnect for optical backplane systems based on printed circuits board is presented for transmitting data via integrated multimode polymer optical waveguides both on electro-optical transmitter/receiver processing boards and on optical backplane board. Different developments concerning this system such as optical waveguide technology,(More)
In this paper two fast frequency domain methods are presented for the determination of the voltages at all terminations of coupled transmission line systems. Algorithms based on these methods can be used for a fast preanalysis of complex PCBs with respect to reflection-and crosstalk effects. The dynamical behaviour of a transmission line system is described(More)
The integration of optical interconnects into electronic systems results in hybrid electrical-optical interconnects. To design such systems the physical behaviour of the electrical and optical parts has to be modeled. The latter one requires the consideration of the technological given facts typical for the addressed interconnection level (component-,(More)
