On the Complexity of Positional Sequencing by Hybridization

Journal of Computational Biology, 1999
In sequencing by hybridization (SBH), one has to reconstruct a sequence from its l-long substrings. SBH was proposed as an alternative to gel-based DNA sequencing approaches, but in its original form the method is not competitive. Positional SBH (PSBH) is a recently proposed enhancement of SBH in which one has additional information about the possible ...

Sequence-dependent Nucleosome Positioning

Journal of Molecular Biology, 2009
Eukaryotic DNA is organized into a macromolecular structure called chromatin. The basic repeating unit of chromatin is the nucleosome, which consists of two copies of each of the four core histones and DNA. The nucleosomal organization and the positions of nucleosomes have profound effects on all DNA-dependent processes.

Position-based sequence weights

Journal of Molecular Biology, 1994
Sequence weighting methods have been used to reduce redundancy and emphasize diversity in multiple sequence alignment and searching applications. Each of these methods is based on a notion of distance between a sequence and an ancestral or generalized sequence.

Positive Dependence of Exchangeable Sequences

Canadian Journal of Mathematics, 1992
AbstractInfinite sequences of exchangeable binary random variables have strong positive dependence properties; in particular, we show they are strong FKG. If the infinite exchangeable sequence is allowed to have multiple values this is no longer true. Positive dependence conditions such as association still have natural application in this context.
