Eds. M. Atkinson and F. Dehne. Volume 41. Australian Computer Science Communications. Volume 27. Number 4. pp. 31--40.

20. On the Computational Power of Probabilistic and Quantum Branching Programs. (with Farid Ablayev, Aida Gainutdinova, Marek Karpinski, and Cristopher Moore). Information and Computation. Dec. 2005. Vol. 203. Iss 2. pp. 145--162.

19. Languages to diagonalize against advice classes. Computational Complexity. Vol. 14 Iss 4. pp. 342--361. 2005. An earlier version with many typos appeared as ECCC TR04-014.

18. Sk, exp does not prove NP=coNP uniformly. Zapiski Nauchnykh Seminarov. Dom 1. Vol. 304. 2003. pp. 99--120. (Without the uniformity condition the result only implies a restricted form of IOpen +exp cannot prove NP = coNP.) Translated from English to English but with some typos eliminated in Journal of Mathematical Sciences. Vol. 130. No. 2. Oct. 2005. pp.4607--4619.

17. A Theory for Logspace and NLIN versus co-NLIN. Journal of Symbolic Logic. Vol. 68 No. 4. 2003. pp. 1082-1090.

16. Nepomnjascij's Theorem and Independence Proofs in Bounded Arithmetic. ECCC TR02-051.

15. Quantum and Stochastic Branching Programs of Bounded Width. (with Farid Ablayev and Cris Moore) 29th International Colloquium on Automata, Languages, and Programming (ICALP). 2002. p.343--354. Earlier versions can be found at ECCC TR02-013 and LANL quant-ph/020113. The upper bound result in the ICALP paper needed a syntactic restriction. This has been revised in the ECCC and LANL version and in the version on-line here.
