The donut and dynamic polarization effects in proton channeling through carbon nanotubes
(New Journal of Physics, 2010)
We investigate the angular and spatial distributions of protons with an energy of 0.223 MeV after channeling them through an (11, 9) single-wall carbon nanotube of 0.2 mu m length. The proton incident angle is varied between ...
Modeling EEG fractal dimension changes in wake and drowsy states in humans—a preliminary study
(Journal of Theoretical Biology, 2010)
Aim of this preliminary study was to examine and compare topographic distribution of Higuchi's fractal dimension (FD, measure of signal complexity) of EEG signals between states of relaxed wakefulness and drowsiness, as ...
