Vyacheslav Futorny and Serge Ovsienko

We introduce a new class of noncommutative rings-Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Galois orders generalizes classical orders in noncommutative rings and contains many classical objects, such as the Generalized Weyl algebras, the universal enveloping algebra of the general linear Lie algebra, assoc...

CHAM Case Study

PHOENICS-2010 has been applied to the simulation of heat transfer within a solar panel design on behalf of the LE2M Laboratory of ICAM, Nantes, France. The panel is assumed to be horizontal and consists of three layers; glass, collector and backboard, with air spaces between. The aim of the panel is to warm air through solar irradiation. The glass and collector gather heat by the "greenhouse ef...

Concurrent Programming in T-cham

A coordination style programming language, T-Cham, is proposed. It is based on the paradigm of the chemical abstract machine (Cham) and transaction programming paradigm. Hierarchical tuple spaces, where the \molecules" of the Cham reside, are used to coordinate the concurrent transactions, which could be written in any language, such as C, Pascal, or Fortran etc., even T-Cham itself, as long as...

Taxonomic updates in Dolichandra Cham. (Bignonieae, Bignoniaceae)

Dolichandra is a genus of lianas found in dry and wet Neotropical forests. The genus currently includes eight species and is well characterized by molecular and morphological synapomorphies. Here, Macfadyenahispida (DC.) Seemann is removed from synonomy with Dolichandrauncata (Andrews) L.G. Lohmann based on the presence of the hispid indument, vinaceus ovary, long fruits, and winged seeds. The ...
