Arbitrary-load-dependent X-parameters, automatically measured with a load-tuner working with an NVNA, are used to characterize and model a packaged 10W GaN transistor. A full nonlinear two-port functional block model for PA and other circuit design is immediately available for nonlinear simulation. It is demonstrated that the model predicts well the(More)
A cDNA expression library of the rumen fungus Neocallimastix patriciarum was made in Escherichia coli. Cellulolytic clones were identified by screening on a medium containing carboxymethylcellulose. Restriction mapping and Southern hybridization analysis of selected clones revealed three distinct cellulase cDNAs, designated celA, celB and celC. Studies on(More)
In a variety of applications it is important to extract information from a probability measure µ on an infinite dimensional space. Examples include the Bayesian approach to inverse problems and possibly conditioned) continuous time Markov processes. It may then be of interest to find a measure ν, from within a simple class of measures, which approximates µ.(More)
—IV knee walkout in AlGaN/GaN high electron mobility transistors (HEMTs) on a Sapphire substrate is analyzed using dynamic radio frequency (RF) load-lines acquired with a large signal network analyzer (LSNA) for both continuous-wave (CW) and pulsed-IV/RF excitations. When thermal effects and traps are bypassed using pulsed-IV biasing and pulsed-RF(More)
[1] In the companion paper, equations for partially molten media were derived using two‐ scale homogenization theory. This approach begins with a grain‐scale description and then coarsens it through multiple scale expansions into a macroscopic model. One advantage of homogenization is that effective material properties, such as permeability and the shear(More)
Serum specimens from 114 patients hospitalized with a febrile illness were tested with an indirect immunofluorescence assay (IFA) using Bartonella antigens prepared from 6 species of sigmodontine rodents and 3 known human Bartonella pathogens: B. henselae, B. quintana, and B. elizabethae. Acute- and convalescent-phase serum samples from 5 of these patients(More)
