Despite the potential for deleterious (even fatal) effects on cardiac physiology, 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) abuse abounds driven mainly by its euphoric effects. Acute exposure to MDMA has profound cardiovascular effects on blood pressure and heart rate in humans and animals. To determine the effects of MDMA on cardiac metabolites in(More)
In this paper, we introduce a new fast, higher-order solver for scattering by inhomogeneous media in three dimensions. As in previously existing methods, the low complexity of our integral equation method, OðN log N Þ operations for an N point discretization, is obtained through extensive use of the fast Fourier transform (FFT) for the evaluation of(More)
This paper provides a theoretical analysis of a higher-order, FFT-based integral equation method introduced recently [IEEE Trans. for the evaluation of transverse electric–polarized electromagnetic scattering from a bounded, pene-trable inhomogeneity in two-dimensional space. Roughly speaking, this method is based on Fourier smoothing of the integral(More)
In animals, repeated administration of 3,4-methylenedioxymethamphetamine (MDMA) reduces markers of serotonergic activity and studies show similar serotonergic deficits in human MDMA users. Using proton-magnetic resonance spectroscopy ((1)H-MRS) at 11.7Tesla, we measured the metabolic neurochemical profile in intact, discrete tissue punches taken from(More)
