In this paper, we investigate the application of the asynchronous logic approach for the realization of ultra high-speed digital electronics with high complexity. We evaluate the possible physical, technological, and schematical origins of restrictio

We present a methodology for the efficient design of transmission line discontinuities utilizing the Finite-Difference Time-Domain embedded within an optimization framework. The specially developed parts of a program system including preprocessor-, s

A digital SQUID with the feedback loop closed on chip was simulated, designed, fabricated and tested. The basic architecture of a delta modulator A/D converter with coarse quantization was implemented using a latching comparator and a write gate whic

Adrenodoxin and the mutants at the positions T54, H56, D76, Y82, and C95, as well as the deletion mutants 4-114 and 4-108, were studied by high-sensitivity scanning microcalorimetry, limited proteolysis, and absorption spectroscopy. The mutants show

A high- T c DC SQUID amplifier has been prepared and tested. The principle of operation of the amplifier was first proved by using low- T c Nb-Al 2 O 3 -Nb SQUIDs with integrated Nb input coils. A flux gain factor of about 20 was demonstrated at 4.2

We report a quantitative calculation of the capacitances of high critical temperature (high‐Tc) Josephson junctions. The matter is of practical interest, because the usual junction realizations cause the conventional plate capacitor formula suffici

The characterization of the current density distribution in an edge-shaped region of a planar YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// flux transformer is reported for the first time. The analysis was performed by means of three-dimensional computatio

Ddx42p is a recently characterized mammalian DEAD box protein with unknown cellular function. We found that in human cells Ddx42p physically interacts with ASPP2, a major apoptosis inducer known to enhance p53 transactivation of proapoptotic genes. T
