This paper presents a highly compact 3 times 3 mm<sup>2</sup> WCDMA power amplifier (PA) module which integrates a GaAs HBT MMIC PA and a Si DC power management IC into one single package. A closed-loop controlled DC-DC buck converter allows the power management IC to adaptively optimize the PA collector voltage as a function of output power and thereby(More)
We purified a 58 kDa serine protease from culture-supernatant of Pichia pastoris and found that the NH2-terminal amino acid sequence of this protease is closely homologous to that of mature protein of Saccharomyces cerevisiae carboxypeptidase Y (CPY), which is encoded by the PRC1 gene. Using the S. cerevisiae PRC1 gene as a hybridization probe, a(More)
Proteins in normal human urine were clearly fractionated into 26 bands with molecular weights from 14,000 to 230,000 by means of one-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) coupled with silver staining. The main band contained uromucoid, and the second main band had albumin. However, when urine samples from healthy(More)
Although the relationship between biological motion perception as depicted by point-light displays and social cognition has been investigated in recent decades, the developmental course of the integration of social cognition and the perception of biological motion is not well understood. To better understand this development, we investigated the ability of(More)
Two serine proteases, arginine esterases (esterases I and II) which showed the activity of tissue prokallikrein activation were identified in rat submandibular gland. These enzymes were separated from the homogenate of rat submandibular gland by two successive DEAE-cellulose chromatographies and were further purified and characterized. Esterases I and II(More)
We describe a female Japanese patient with concomitant hypocomplementemic urticarial vasculitis, Jaccoud's arthropathy and valvular heart disease. In 1996, she developed arthritis with swelling of both proximal interphalangeal joints and urticarial vasculitis on both arms that was resolved by administration of glucocorticoid (prednisolone 30 mg/day). Tests(More)
Human infants can consider humans as collaborative agents, but little is known about whether they also recognize robots as collaborative agents. This study investigated that how infants understand robot agents while they watched collaborative interactions between a human and a robot. We presented a novel visual habituation paradigm in which a human and a(More)
Antibacterial activity of various antibiotics against Pseudomonas aeruginosa isolated from each hospitals depends on the variety or amount of antibiotics used in each hospital. The antibiotic, which is effective to P. aeruginosa in a certain hospital is not always effective to that in other hospital. The excellent antibiotics in antibacterial activity have(More)
MICs of piperacillin, sulbactam/cefoperazone, minocycline (MINO), gentamicin, amikacin, flomoxef, ceftazidime, cefozopran, cefsulodin and imipenem were determined, against 189 clinical isolated strains of glucose non-fermentative Gram-negative Rods (NFGNR; Acinetobacter baumannii (44), Alcaligenes faecalis (5), Alcaligenes xylosoxidans (25), Burkholderia(More)
