Abstract This paper presents the construction of RLL-ECCs (run length limited error control codes) from three selected ECCs specified by Consultative Committee for Space Data Systems (CCSDS) optical communications. The obtained present a practical alternative to CCSDS codes with pseudo-randomizers. Their advantage is that maximal run lengths equal symbols in their codeword sequences are guarant...

We showed recently that Golomb codes can be used for efficiently compressing system-on-a-chip test data. We now present a new class of variable-to-variable-length compression codes that are designed using the distributions of the runs of 0s in typical test sequences. We refer to these as frequency-directed run-length (FDR) codes. We present experimental results for the ISCAS 89 benchmark circui...

This paper describes a synthetic dimer of carbonic anhydrase, and a series of bivalent sulfonamide ligands with different lengths (25 to 69 Å between the ends of the fully extended ligands), as a model system to use in examining the binding of bivalent antibodies to antigens. Assays based on analytical ultracentrifugation and fluorescence binding indicate that this system forms cyclic, noncoval...

Analytical techniques Ageand sex-adjusted prevalence rates of depression and alcohol in immigrants and the Canadian-born population were compared. Variation by length of residence in Canada and country of birth was examined. Multivariate logistic regression models were run separately for depression and alcohol dependence, with adjustment for age, sex, marital status, income, and education. The ...
