      abstract     = {Fluctuations and damages crucially determine the operation
                      and stability of networked systems across disciplines, from
                      electrical powergrids, to vascular networks or neuronal
                      networks. Local changes in the underlying dynamics may
                      affect the whole network and, in the worst case, cause a
                      total collapse of the system through a cascading failure. It
                      has been demonstrated that certain subgraphs can reduce
                      failure spreading drastically, or even inhibit it
                      completely. However, this shielding effect is poorly
                      understood for non-linear dynamical models. Here, we study
                      the effect of perturbations in networks of oscillators
                      coupled via the Kuramoto model. We demonstrate how the
                      network structure can be optimised for suppressing specific,
                      targeted fluctuations at a desiredoperational state while
                      letting others pass. We illustrate our approach by
                      demonstrating that a significant reduction in time-dependent
                      fluctuations may be achieved by optimising the edge weights.
                      Finally, we demonstrate how to apply the developed method to
                      real-world supply networks such as power grids. Our findings
                      reveal that a targeted shielding of specific solutions in
                      multistable systems is possible which may be applied to make
                      supply networks more robust.},
