Studied in this paper are hybrid multirate lter banks which consist of analog analysis lters, slow A/D converters, digital expanders, and digital synthesis lters. The synthesis lters are designed to minimize the maximum energy gain of the error system, suitably weighted, between the lter bank and a fast A/D converter with some time delay. This hybrid and(More)
OBJECTIVE Peripheral hearing loss has been commonly reported in children with non-syndromic cleft lip and/or palate (NSCLP) but few studies have provided information about central auditory nervous system (CANS) functioning for this group. The main objective of this study was to explore CANS functioning in infants with NSCLP through analysis of auditory(More)
OBJECTIVE To investigate possible structural abnormalities of the central auditory pathway in infants with nonsyndromic cleft lip and/or palate (NSCL/P). PARTICIPANTS Twenty-seven Chinese infants with NSCL/P, aged from 6 to 24 months. INTERVENTION Morphological magnetic resonance imaging (MRI) measurements of the central auditory nervous system (CANS)(More)
Orphanin FQ (OFQ) is a novel peptide comprised of an amino acid sequence very similar to that of dynorphin A. In the present investigation the effect of OFQ on cardiovascular activities was studied. Introcerebroventricular (icv) injection of OFQ at doses of 1 and 10 micrograms produced significant decrease in heart rate (HR) and mean arterial pressure(More)
For a single-machine, innnite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H1 optimization. The digital stabilizers designed have low orders, require considerably slow sampling rates for implementation, and out-perform the conventional (analog) power system stabilizer on a(More)
The effects of leucine-enkephalin (Leu-Enk) on colonic mechanoreceptor input to the inferior mesenteric ganglion (IMG) and on colonic intraluminal pressure of the guinea pig were studied in vitro. Superfusion of the IMG with Leu-Enk decreased colonic, afferent mechanoreceptor synaptic input. In neurons in which mechanoreceptor input caused postsynaptic(More)
