OBJECTIVE While 65%-80% occupancy of dopamine D2 receptors with antipsychotics has been proposed to achieve optimal therapeutic response during acute treatment of schizophrenia, it remains unclear as to whether it is also necessary to maintain D2 receptor occupancy within this "safe" window for ongoing maintenance treatment. The data are especially scarce(More)
BACKGROUND Clinical relevance of dental caries is often underestimated in patients with schizophrenia. The objective of this study was to examine dental caries and to identify clinical and demographic variables associated with poor dental condition in patients with schizophrenia. METHODS Inpatients with schizophrenia received a visual oral examination of(More)
Two kinds of signal processing techniques for ground penetrating radar (GPR) are applied to measured GPR data in order to improve performance of target identification. One is the method for removing strong ground clutter that covers a weak target response in time domain, and the other is the calibration procedure of GPR response for removing undesirable(More)
This paper reports on what is believed to be the highest IP3/P/sub DC/ power linearity figure of merit (LFOM) achieved from a MMIC amplifier at millimeter-wave frequencies. The 44 GHz amplifier is based on an InP HBT technology with f/sub T/s and f/sub max/s of 70 GHz and 200 GHz respectively. The single stage design consists of four pre-matched 1/spl(More)
