New control circuits and algorithms are frequently proposed to control the impedance (Z) source inverter in efficient way with added benefits. As a result, several modified control techniques have been proposed in recent years. Although these techniques are clearly superior to the simple boost control method which was initially proposed along with the Z-source inverter (ZSI), little or conf...

The administration of aripiprazole (ARI), a dopamine partial agonist, could provoke abrupt psychotic worsening in patients with schizophrenia. We explored the relationship between this psychotic worsening and dopamine supersensitivity psychosis (DSP), which is a clinically vulnerable state. We conducted a retrospective investigation for 264 patients whose treatment medication was switched to AR...

We present a special-purpose computer architecture for the qualitative simulator QSim, which is mainly used in artiicial intelligence (AI) applications. This architecture consists of DSPs TMS320C40 and specialized coprocessors (Xilinx FPGAs). We stress the distinct algorithm characteristic of qualitative simulation compared to DSP applications. We also demonstrate the suitability of the DSP TMS...

OBJECTIVE Previous studies demonstrate that the metabolic syndrome is associated with distal symmetric polyneuropathy (DSP). We aimed to determine the magnitude of this effect and the precise components involved. RESEARCH DESIGN AND METHODS We determined the symptomatic DSP prevalence in the Health, Aging, and Body Composition (Health ABC) study (prospective cohort study, with subjects aged 7...

OBJECTIVES To determine whether digital signal processing (DSP) hearing aids produce conducted radio frequency interference that can affect the use of personal FM systems, to quantify the nature of any such interference, and to discuss practical remedies. DESIGN Sixteen DSP hearing aids were used. Measurements were made of the spectral characteristics of any conducted radio frequency interfer...

Bovine pulmonary surfactant protein C (SP-C) is a hydrophobic, alpha-helical membrane-associated lipoprotein in which cysteines C4 and C5 are acylated with palmitoyl chains. Recently, it has been found that the alpha-helix form of SP-C is metastable, and under certain circumstances may transform from an alpha-helix to a beta-strand conformation that resembles amyloid fibrils. This transformatio...

OBJECTIVE Axon reflex-mediated neurogenic vasodilatation in response to cutaneous heating may reflect early, pre-clinical small fibre dysfunction. We aimed to evaluate the distribution of the vascular flare area measured by laser doppler imaging ("LDI(FLARE) area") in type 1 diabetes and in healthy volunteers. RESEARCH AND METHODS Concurrent with clinical and electrophysiological examination ...
