A technique is discussed for the design of multiple access frequency hopping patterns which will allow a number of users to communicate reliably over a limited bandwidth in the presence of Doppler and timing asynchronies. The patterns are based on a subset of the Reed-Solomon codewords. They possess nearly flat ambiguity and cross-ambiguity functions and(More)
A high molecular weight acyl coenzyme A (acyl-CoA) thioesterase, designated thioesterase II, has been purified 5300-fold from photoheterotrophically grown cells of Rhodopseudomonas sphaeroides. In contrast to R. sphaeroides acyl-CoA thioesterase I [Boyce, S.G., & Lueking, D.R. (1984) Biochemistry 23, 141-147], thioesterase II has a native molecular mass(More)
