Products of Universal Cycles
Universal cycles are generalizations of de Bruijn cycles to combinatorial patterns other than binary strings. We show how to construct a product cycle of two universal cycles, where the window widths of the two cycles may be different. Applications to card tricks are suggested.
متن کاملWeak Products of Universal Algebras
Weak direct products of arbitrary universal algebras are introduced. The usual notion for groups and rings is a special case. Some universal algebraic properties are proved and applications to cylindric and polyadic algebras are considered.
متن کاملSensitive and universal method for microbial DNA extraction from blood products.
A new method of extracting bacterial and yeast DNA from blood products dependent on guanidinium thiocyanate acid extraction and proteinase K treatment is described. In spiked samples the sensitivity per 0.1 ml of serum and blood, respectively, was 26 and 150 colony forming units (cfu) for Escherichia coli, 80 and 120 cfu for Staphylococcus aureus and 20 and 26 cfu for Candida albicans. This com...
متن کاملProducts of the Universal Treeable Relation, I
(see Hjorth-Kechris [96], Jackson-Kechris-Louveau [00]) and, before the results in Adams-Kechris [00], this gave the only examples of distinct (up to ∼B) non-smooth countable Borel equivalence relations, 4 of them to be exact. In this note, we point out that there is in fact one more strict inequality in the above chain, thereby establishing a 5th distinct example in that list. Theorem 1 E∞T ×E...
متن کاملImmunological reactions to blood and blood products.
All blood cells possess inherited antigens; their pattern is specific for any individual or groups of individuals, and remains constant throughout life. Although the majority of the antigens were first recognized in association with blood cells, it is now evident that many of them are also found in other tissues and in body fluids, and specific antigens have been demonstrated in plasma. Antibod...
