New discoveries about neurogenesis prompt reevaluation of cerebral development. By Ken Howard. For the past several decades, scientists believed that brain cells were a finite resource; that unlike other cells in the body, those in the brain did not regenerate.Elizabeth Gould (photo by Denise Applewhite).ew discoveries about neurogenesis prompt reevaluation of cerebral development.

communication deadlock occurs when process A is trying to send a message to process B, which is trying. to send a message to process C which is trying to send a message to A. A resource deadlock occurs when processes are trying to get exclusive access to devices, files, locks, servers, or other resources. We will not differentiate between these types of deadlock since we can consider communication channels to be resources without loss of generality. Four conditions have to be met for deadlock to be present: 1.
communication network. Without loss of generality we assume that each process is running on a different processor. The processors do not share a common global memory and communicate solely by passing messages over the communication network. A. Kshemkalyani and M. Singhal Deadlock Detection in Distributed Systems In deadlock avoidance approach to distributed systems, a resource is granted to a process if the resulting global
