We introduce a collection of new operations on hypermaps, partial duality, which include the classical Euler-Poincaré dualities as particular cases. These operations generalize the partial duality for maps, or ribbon graphs, recently discovered in a connection with knot theory. Partial duality is different from previous studied operations of S. Wilson, G. Jones, L. James, and A. Vince. Combinat...

Two new pregnane glycosides, cynascyrosides D and E, were isolated from the roots of Cynanchum ascyrifolium. The structures of these compounds were determined on the basis of spectroscopic and chemical evidence as cynajapogenin A 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-digitoxopyranosyl-(1-->4)-beta-L-cymaropyranoside and cynajapogenin A 3-O-beta-D-glucopyranosyl-(1-->4)-alpha-L-diginopyrano...

In this paper, the multivariate fractional trading ansatz of money management from Vince (Vince 1990) is discussed. In particular, we prove existence and uniqueness of an “optimal f ” of the respective optimization problem under reasonable assumptions on the trade return matrix. This result generalizes a similar result for the univariate fractional trading ansatz. Furthermore, our result guaran...

This paper presents the chromosome numbers (2n) for 13 alien species (from families Apocynaceae, Asteraceae, Brassicaceae, Fabaceae, Lamiaceae, Polygonaceae, Solanaceae) in Novosibirsk Region. For Vincetoxicum hirundinaria Medik. (2n = 22) and Sisymbrium altissimum L. 14), were determined first time on material from Russia; Betonica officinalis 16) – Asian Stachys annua (L.) 34) West Siberia. C...
