We study the topology and combinatorics of an arrangement of hyperplanes in C n that generalizes the classical braid arrangement. The arrangement plays in important role in the work of Schechtman & Varchenko 12, Part II] on Lie algebra homology, where it appears in a generic ber of a projection of the braid arrangement. The study of the intersection lattice of the arrangement leads to the deeni...

In this paper, we propose a distributed broadcasting algorithm with optimal time complexity and without message redundancy for one-toall broadcasting in the one-port communication model on arrangement graph interconnection networks. The algorithm exploits the hierarchical property of the arrangement graph to construct different-sized broadcasting trees for different-sized subgraphs. These diffe...

We tested the hypothesis that spatial arrangement and movements of bottlenose dolphins (TursiopJ truncatm) are related to the spatial arrangement of their prey. From 65 groups we: (1) classified feeding behavior of dolphins according to spatial arrangement and movements of individuals; (2) assessed spatial arrangement and location of prey from direct observations, numbers of associated seabirds...

Automatic generation of guitar tablatures for given songs has been one of research interests in music information processing. Furthermore, some of recent studies have attempted automatic arrangement of given songs before tablature generation for producing guitar scores for songs composed for other instruments. In our previous work, we have formulated “fingering decision” and “arrangement” in a ...

It has been known that topologically different proteins of the same class sometimes share the same spatial arrangement of secondary structure elements (SSEs). However, the frequency by which topologically different structures share the same spatial arrangement of SSEs is unclear. It is important to estimate this frequency because it provides both a deeper understanding of the geometry of protei...

Many theories of grammar make a sharp distinction between the arrangement of words within a clause and the arrangement of morphemes within a word (but see Baker 1988). What is unfortunate about this distinction is that theories of syntax provide universal and well-motivated operations to account for the arrangement of words within a clause, while the arrangement of morphemes within a word is re...

We discuss different variants of linear arrangement problems from a parameterized perspective. More specifically, we concentrate on developing simple search tree algorithms for these problems. However, the analysis of these algorithms is sometimes not so easy.

Fish respire through gills, which have evolved to extract aqueous oxygen. Fish gills consist of filaments with well-ordered lamellar structures, which play a role in maximizing oxygen diffusion. It is interesting that when we anatomically observe the gills of various fish species, gill interlamellar distances (d) vary little among them, despite large variations in body mass (Mb). Noting that th...
