  Dynamic fluctuations in the local density of non-identified hadron tracks
reconstructed in the STAR TPC are studied using the discrete wavelet transform
power spectrum technique which involves mixed event reference sample
comparison. The two-dimensional event-by-event analysis is performed in
pseudo-rapidity (eta) and azimuthal angle (phi). HIJING simulations indicate
that jets and mini-jets result in signals, visible without high pT selection,
when the dynamic texture analysis is applied. Scanning a broad range of event
multiplicities, we study the dependence of the signals on the initial
conditions. Event structures are studied separately with positive and negative
tracks, as well as both charges. A change of regime is observed in AuAu
collisions at sqrt(S_NN}=130 GeV as event multiplicity is increased: a long
range eta correlation (or suppressed fluctuation vis-a-vis mixed events) is
seen in same charge data. This effect is qualitatively similar to one of the
predicted manifestations of the Color Glass Condensate.
