  We consider chains of rotors subjected to both thermal and mechanical
forcings,in a nonequilibrium steady-state. Unusual nonlinear profiles of
temperature and velocities are observed in the system. In particular, the
temperature is maximal in the center, which is an indication of the nonlocal
behavior of the system. In spite of that, local equilibrium holds for long
enough chains. Our numerical results also show that, when the mechanical
forcing is strong enough, the energy current can be increased by an inverse
temperature gradient. This counterintuitive result again reveals the complexity
of nonequilibrium states.
