The classification theory for shifts of finite type (topological Markov chains) in the strictest sense, that is to say, up to topological conjugacy, was initiated by Williams ([17]). Additions toâ€¦ (More)

We use GrÃ¶bner bases and a theorem of Handelman to show that an ideal I of R[x1, . . . , xk] contains a polynomial with positive coefficients if and only if no initial ideal inv(I), v âˆˆ R, has aâ€¦ (More)

We introduce a new type of invariant of block isomorphism for Markov shifts, defined by summing the weights of all spanning trees for a presentation of the Markov shift. We give two proofs ofâ€¦ (More)

A newly designed glass-PDMS microchip-based sensor for use in the determination of Ca(2+) ions has been developed, utilizing reflectance measurements from arsenazo IIIâ€¦ (More)

We prove several theorems about automorphisms of Markov chains, using the weight-per-symbol polytope. Introduction The main purpose of this paper is to show how the weight-per-symbol polytope (WPS),â€¦ (More)

A random oligomer of N-isopropylacrylamide (NIPAAm) and acrylic acid (AAc) with a AAc content of 3.1+/-0.19 mmol carboxylic acid groups per gram of the oligomer and with a number average molecularâ€¦ (More)

99Tcm-latex particles (LP) is a newly developed radiopharmaceutical for the evaluation of the gastrointestinal (GI) tract. Following oral ingestion, it passes through the entire GI tract undissolved.â€¦ (More)

Latex particles coated with either amino or carboxyl groups were labelled with 99mTc. Two labelling methods were used: (1) direct labelling with tin reduction and (2) ligand exchange with tinâ€¦ (More)
