The real casualty number from use of cluster munitions in the conflict is probably higher, Human Rights Watch said, since it has not investigated all allegations of cluster munition use.

The connection between symmetries and cluster synchronization is experimentally confirmed in the context of real networks with heterogeneities and noise using an electro-optic network.

This Hubble Space Telescope composite image shows a ghostly "ring" of dark matter in the galaxy cluster Cl 0024+17 in this stunning space wallpaper.

Once the service is running on all nodes, the command corosync-cfgtool -s will display both rings as healthy, and the cluster is ready to communicate: Printing ring status.
