Discovering the structure of complex networks by minimizing cyclic bandwidth sum
CoRR, 2014 Getting a labeling of vertices close to the structure of the graph has been proved to be of interest in many applications e.g., to follow smooth signals indexed by the vertices of the network. This question can be related to a graph labeling problem known as the cyclic bandwidth sum problem.

Pulsar Cyclic Spectroscopy in the Partial-deconvolution Regime: Benefits and Limitations
The Astrophysical JournalWe explore possible advantages of cyclic spectroscopy for observations of pulsars in instances where full cyclic deconvolution is not possible. We compute cyclic merits and full-deconvolution regime boundaries for pulsars observed by NANOGrav and discuss
