Query: On the dynamics of traveling phase-oscillators with positive and
  negative couplings   We investigate numerically the dynamics of traveling clusters in systems of
phase oscillators, some of which possess positive couplings and others negative
couplings. The phase distribution, speed of traveling, and average separation
between clusters as well as order parameters for positive and negative
oscillators are computed, as the ratio of the two coupling constants and/or the
fraction of positive oscillators are varied. The traveling speed depending on
these parameters is obtained and observed to fit well with the numerical data
of the systems. With the help of this, we describe the conditions for the
traveling state to appear in the systems with or without periodic driving.
