Abstract This paper provides the first thorough assessment of a physics-based answer, Bound State Answer (BSA), to Special Composition Question (SCQ). According BSA some objects compose something if they are in common bound state. The reasons endorse such an particular, motivations coming from empirical adequacy and conservativeness, precision, simplicity, parsimony, critically addressed. I the...

A typical interval exchange transformation has an infinite sequence of matrices associated to it by successive iterations Rauzy induction. In 2010, W. A. Veech answered a question Bufetov showing that the itself may be recovered from these and must unique up topological conjugation. this work, we will improve upon results providing algorithm determine initial sufficiently long finite subsequenc...

the present study aimed to use a method for the synthesis of some 3, 4-dihydropyrimidin-2-(1h) - ones/thiones. the study tried to answer the question whether this reaction can be performed without solvent and with new catalyst or not. to find answer to the question, we described a novel protocol for the efficient synthesis of 3, 4-dihydropyrimidin-2-(1h)-one derivatives using aromatic aldehyde,...
