Description: The MRI machine is undergoing change in how it is used. Used conventionally, it produces images, which are viewed qualitatively by radiologists. Unusually dark, light, large or small areas are noted, and subtle changes cannot be detected. In its new use,that of a scientific instrument making measurements in the human brain, a myriad of physical(More)
We study an ensemble of random walkers carrying internal noisy phase oscillators which are synchronized among the walkers by local interactions. Due to individual mobility, the interaction partners of every walker change randomly, hereby introducing an additional, independent source of fluctuations, thus constituting the intrinsic nonequilibrium nature of(More)
Recently, we proposed a self-propelled particle model with competing alignment interactions: nearby particles tend to align their velocities whereas they anti-align their direction of motion with particles which are further away [R. Großmann et al., Phys. Rev. Lett. 113, 258104 (2014)]. Here, we extend our previous numerical analysis of the high density(More)
