abstract = {<p style="text-align: justify;">In some applications, there are signals with piecewise structure to be recovered. In this
paper, we propose a piecewise_ISS (P_ISS) method which aims to preserve the piecewise
sparse structure (or the small-scaled entries) of piecewise signals. In order to avoid selecting
redundant false small-scaled elements, we also implement the piecewise_ISS algorithm in
parallel and distributed manners equipped with a deletion rule. Numerical experiments
indicate that compared with aISS, the P_ISS algorithm is more effective and robust for
piecewise sparse recovery.</p>},
