The issue of amalgams.
We developed OligoCalc as a web-accessible, client-based computational engine for reporting DNA and RNA single-stranded and doublestranded properties, including molecular weight, solution concentration, melting temperature, estimated absorbance coefficients, inter-molecular self-complementarity estimation and intramolecular hairpin loop formation. OligoCalc has a familiar ‘calculator’ look and ...

متن کاملAmalgams and the Coset Graph
Informally, an amalgam is a group ‘sitting inside’ two other groups and the coset graph is a way to look at how the cosets of subgroups interact. These are combined in the amalgam method — a way of classifying amalgams satisfying certain conditions. The amalgam method was used in the classifications of finite simple groups, and is discussed in Classification of Finite Simple Groups no. 2 by Gor...
متن کاملAmalgams of Free Inverse Semigroups
We study inverse semigroup amalgams of the form S U T where S and T are free inverse semigroups and U is an arbitrary nitely generated inverse subsemigroup of S and T. We make use of recent work of Bennett to show that the word problem is decidable for any such amalgam. This is in contrast to the general situation for semigroup amalgams, where recent work of Birget, Margolis and Meakin shows th...
