Abstract We study the effect of quantum decoherence on inflationary cosmological perturbations. This process might imprint specific observational signatures revealing nature mechanism being related to longstanding issue quantum-to-classical transition fluctuations. Several works have investigated statistical properties primordial In particular, it has been shown that cosmic leads corrections cu...

Randomized modulation of switching in power converters holds promise for reducing filtering requirements and reducing acoustic noise in motor drive applications. This paper is devoted to issues in analysis and synthesis of randomized modulation schemes based on finite Markov chains. The main advantage of this novel type of randomized modulation is the availability of an explicit control of time...

OBJECTIVES To examine differences in power spectra and intra-hemispheric coherence between the left and right hemispheres in the presence of severe asymmetric brain damage. METHODS Power spectra and coherence functions were computed for a patient with severe damage to subcortical gray matter structures on the right side but relative preservation on the left. RESULTS Power spectra differed m...
