A new noise-figure measurement method, which combines the simplicity of the "classical" Y-factor method with the accuracy of the widely used "cold noise-source" method, is reported. Implemented in our fully automated wide-band 1-18-GHz on-wafer noise-parameter measurement system, accurate results are obtained using a small set of precharacterized source(More)
PURPOSE Identification of minor histocompatibility antigens (mHag) with classic methods often requires sophisticated technologies, determination, and patience. We here describe and validate a nonlaborious and convenient genetic approach, based on genome-wide correlations of mHag zygosities with HapMap single-nucleotide polymorphism genotypes, to identify(More)
The Kondo effect is usually connected with the interaction between a localized spin moment and itinerant electrons. This interaction leads to the formation of a narrow resonance at the Fermi level, which is called the Abrikosov-Suhl or Kondo resonance. Scanning tunnelling microscopy is an ideal technique for real-space investigations of complicated(More)
