Brownian Motion on the Figure Eight
In an interval containing the origin we study a Brownian motion which returns to zero as soon as it reaches the boundary. We determine explicitly its transition probability, prove it is ergodic and calculate the decay rate to equilibrium. It is shown that the process solves the martingale problem for certain asymmetric boundary conditions and can be regarded as a diffusion on an eight shaped do...
متن کاملSymmetric orbits arising from Figure-Eight for N-body problem
In this paper, we first describe how we can arrange any bodies on Figure-Eight without collision in a dense subset of [0, T ] after showing that the self-intersections of Figure-Eight will not happen in this subset. Then it is reasonable for us to consider the existence of generalized solutions and non-collision solutions with Mixed-symmetries or with Double-Eight constraints, arising from Figu...
متن کاملEccentric figure-eight coils for transcranial magnetic stimulation.
Previously we proposed an eccentric figure-eight coil that can cause threshold stimulation in the brain at lower driving currents. In this study, we performed numerical simulations and magnetic stimulations to healthy subjects for evaluating the advantages of the eccentric coil. The simulations were performed using a simplified spherical brain model and a realistic human brain model. We found t...
متن کاملA Novel Figure-Eight Coil for Skin Imaging at 7T
Introduction: Noninvasive skin imaging requires very high spatial resolution and high SNR in a FOV on the order of 10 x 10 cm coupled with an acceptable scan time. These requirements are mandatory for characterization of healthy skin, inflammatory skin diseases, and differentiation of skin tumors. To image such microscopic structures within the human skin in vivo, special coil setups are used a...
متن کاملRhythmic muscular activation pattern for fast figure-eight movement.
OBJECTIVE To address the question of how the CNS generates muscle activation patterns for complex gestures, we have chosen to study a figure-eight movement. We hypothesized that the well defined rhythmic aspect of this figure will provide further insights into the temporal features of multi-muscular commands. METHODS Subjects performed, as fast as possible, figure-eights initiated in the cent...
