Previous positron emission tomography (PET) studies with fluorodeoxglucose (FDG) as tracer in healthy elders showed that the epsilon4 allele of the apolipoprotein E (ApoE) gene is disruptive to cerebral glucose metabolism (rCMRglu), possibly through the interaction with the aging process. The present study was aimed at assessing whether this interaction(More)
BACKGROUND Clinically apparent Alzheimer's disease (AD) is thought to result when brain tissue damage exceeds a critical threshold of "brain reserve", a process possibly accelerated by the apolipoprotein E (ApoE) E4 allele. The interaction between onset age and ApoE genotype was investigated to assess whether early disease onset (<65 years) in patients(More)
This FDG-PET study with SPM99 compared 46 patients with sporadic Alzheimer disease (SAD) to 40 patients with familial AD (FAD) and to 35 matched controls. AD groups had equivalent metabolic (METglu) reductions in several cortical and limbic areas with respect to the controls. Patients with FAD showed decreased METglu in the posterior cingulate,(More)
This paper deals with the extension of earlier work [3] (designed for Fredholm and Voltera integral equations), [16] (designed for Fredholm and Voltera integro-differential equations of first-order) and [4] (designed for Fredholm and Voltera integro-differential equations of second-order) to third-order nonlinear Fredholm as well as nonlinear Voltera(More)

Harmonic modeling for power systems involves the incorporation of device models into a power system model. The development of accurate system models for harmonic studies involves the selection of the devices to include in the model as well as the selection of device models which achieve a balance between complexity and accuracy for the study in question.(More)
