EPC syntheses and structureâactivity relationships of hypoglycaemic semicyclic amidines
European Journal of Medicinal Chemistry, 2000A series of homochiral sterically hindered mono- and bicyclic amidines was prepared as hypoglycaemic agents by lethargic reaction of O-methylcaprolactim and 3-ethoxy-2-azabicyclo[2.2.2]oct-2-ene, respectively, with homochiral cis-2-substituted cyclopentane amines provided by asymmetrical reductive amination of racemic 2-substituted cyclopentanones.

Human Exploration of Mars via Earth-Mars Semicyclers
Journal of Spacecraft and Rockets, 2007We present an architecture for the human exploration of Mars. This architecture is characterized by the use of parking orbits at Earth and gravity assists at Mars. An interplanetary transfer vehicle cycles from Earth orbit to Marsflyby andback, eliminating the need to launch transfer vehicles from the surfaces ofEarth andMars.Necessary developments for

Two-Dimensional Optical Orthogonal Codes and Semicyclic Group Divisible Designs
IEEE Transactions on Information Theory, 2010A (nxm, k, ?) two-dimensional optical orthogonal code (2-D OOC), C, is a family of nxm (0, 1)-arrays of constant weight k such that ?i=1n?j=0m-1A(i, j)B(i, j?m?) ? ? for any arrays A, B in C and any integer ? except when A = B and ? ? 0 (mod m ), where ?m denotes addition modulo m.
