One dimensional systems are under intense investigation, both fromtheoretical and experimental points of view, since they have rather peculiarcharacteristics which are of both conceptual and technological interest. Weanalyze the dependence of the behaviour of one dimensional, time reversalinvariant, nonequilibrium systems on the parameters defining their microscopicdynamics. In particular, we consider chains of identical oscillatorsinteracting via hard core elastic collisions and harmonic potentials, driven byboundary Nos\'e-Hoover thermostats. Their behaviour mirrors qualitatively thatof stochastically driven systems, showing that anomalous properties are typicalof physics in one dimension. Chaos, by itslef, does not lead to standardbehaviour, since it does not guarantee local thermodynamic equilibrium. Alinear relation is found between density fluctuations and temperature profiles.This link and the temporal asymmetry of fluctuations of the main observablesare robust against modifications of thermostat parameters and againstperturbations of the dynamics.
