abstract = "The unstable periodic orbits (UPOs) embedded in a chaotic
attractor after an attractor merging crisis (MC) are classified
into three subsets, and employed to reconstruct chaotic saddles in
the Kuramoto-Sivashinsky equation. It is shown that in the post-MC
regime, the two chaotic saddles evolved from the two coexisting
chaotic attractors before crisis can be reconstructed from the
UPOs embedded in the pre-MC chaotic attractors. The reconstruction
also involves the detection of the mediating UPO responsible for
the crisis, and the UPOs created after crisis that fill the gap
regions of the chaotic saddles. We show that the gap UPOs
originate from saddle-node, period-doubling, and pitchfork
bifurcations inside the periodic windows in the post-MC chaotic
region of the bifurcation diagram. The chaotic attractor in the
post-MC regime is found to be the closure of gap UPOs.",
