  We report on the pT dependence of nuclear modification factors ($R_{CP}$) for
Ks, Lambda, Xi and the Anti-Lambda/Ks ratios at mid-rapidity from Au+Au
collisions at \sqrt{s_{NN}} = 39, 11.5 and 7.7 GeV. At \sqrt{s_{NN}} = 39 GeV,
the $R_{CP}$ data shows a baryon/meson separation at intermediate pT and a
suppression for Ks for pT up to 4.5 GeV/$c$; the Anti-Lambda/Ks shows baryon
enhancement in the most central collisions. However, at \sqrt{s_{NN}} = 11.5
and 7.7 GeV, $R_{CP}$ shows much less baryon/meson separation and
Anti-Lambda/Ks shows almost no baryon enhancement. These observations indicate
that the matter created in Au+Au collisions at \sqrt{s_{NN}} = 11.5 or 7.7 GeV
might be distinct from that created at \sqrt{s_{NN}} = 39 GeV.
