To minimize the access cost in large disk arrays (RAID) Cohen et al. [5–7] introduced (d, f)-cluttered orderings of various set systems, d, f ∈ N. In case of a graph this amounts to an ordering of the edge set such that the number of points contained in any d consecutive edges is bounded by the number f. For the complete graph, Cohen et al. gave some(More)
Mechanisms generating diverse cell types from multipotent progenitors are crucial for normal development. Neural crest cells (NCCs) are multipotent stem cells that give rise to numerous cell-types, including pigment cells. Medaka has four types of NCC-derived pigment cells (xanthophores, leucophores, melanophores and iridophores), making medaka pigment cell(More)
The gene encoding 2-oxo-hept-3-ene-1,7-dioic acid (OHED) hydratase (HpcG) was cloned into the high-expression plasmid pET26b and overexpressed in Escherichia coli BL21(DE3). The enzyme was purified in three steps to greater than 95% purity prior to crystallization. Crystals were obtained by the hanging-drop vapour-diffusion method at 277 K in a number of(More)
