Jeffrey C. Lagarias* ([email protected]), Dept. of Mathematics, University of Michigan, 530 Church Street, Ann Arbor, MI 48109-1043. From Apollonian circle packings to Fibonacci numbers. Apollonian circle packings are infinite packings of circles, constructed recursively from a initial configuration of four mutually touching circles by adding circles externally tangent to triples of such circl...

Recent developments in the field of lipid biology have shown conjugated linoleic acids (CLA) to have remarkable yet inconsistent metabolic effects in mice, rats, hamsters, chickens, cows, and humans. In particular, effects on lipogenesis vary with tissue, physiological state, and specie. In this study, sub-adult (7 wk) and adult (11 wk) moulard ducks were grouped by age and fed a standard corn-...

My mathematical interests lie mainly in the field of combinatorics and how combinatorics can be used to prove algebraic identities. My current research is in the area of enumerative and algebraic combinatorics with an emphasis on counting the number of patterns which occur in words and permutations. This has been a very active area of research in recent years and there is a yearly conference, P...

it. The global agribusiness company Syngenta, which was set up in 2000 in the merger of the agricultural divisions of Novartis and AstraZeneca, also supports the project. Principal investigator Maarten Van Helden from the National School for Agricultural Engineers at Bordeaux has been running the project for around two years with his research staff and Syngenta employees, but this year, volunte...

Characteristics Higher Level Structures SEF is located at the rostral end of the supplementary motor area, contiguous with the representation of orofacial, pinna and forelimb movements. SEF is located in Brodman’s area 6 and corresponds to area F7 [1]. The human SEF is located on the medial surface of the superior frontal gyrus in the upper part of the paracentral sulcus (Fig. 1). 10.1007/978-3...
