      Two-phase commit processing with restructured commit tree 

      Samaras, George S.; Kyrou, G. K.; Chrysanthis, Panos K. (2003)
      Extensive research has been carried out in search for an efficient atomic commit protocol and many optimizations have been suggested to improve the basic two-phase commit protocol, either for the normal or failure case. ...

      Reconciling chained and unchained transactional support for distributed systems 

      Samaras, George S.; Citron, A.; Kshemkalyani, A. (1997)
      Distributed transactions require transaction processing support either from their communications protocols or from protocols at some higher layer. One of the earliest "industrial-strength" distributed transactional support ...
