We show that closed arithmetic hyperbolic 3-dimensional orbifolds with larger and volumes give rise to triangulations of the underlying spaces whose 1-skeletons are harder embed nicely in Euclidean space. To this we generalize an inequality Gromov Guth n-orbifolds find nearly optimal geodesic 3-orbifolds.

BACKGROUND We investigated the coronary arterial origins and course and the position of the great arteries in hearts with discordant ventriculoarterial connections. At the same time, we sought to evaluate the practicality of alphanumeric classifications in accounting for surgically relevant features of the coronary arteries. METHODS AND RESULTS We studied 200 postmortem hearts, noting the pat...

We propose a model Hamiltonian for charge transfer along the DNA double helix with temperature-driven fluctuations in the base pair positions acting as the rate limiting factor for charge transfer between neighboring base pairs. We compare the predictions of the model with the recent work of Barton and Zewail on the unusual two-stage charge transfer of DNA.

We describe the generation of a library of eyes surrounded by only one chain which we call monolithic eyes. Apart from applying the library in the life & death program GoTools it also can be used as a source for the study of unusual positions in Go as done in the second half of the paper.

Parallel tree skeletons are basic computational patterns that encourage us to develop parallel programs manipulating trees. In this paper, we develop an efficient implementation of parallel tree skeletons on distributed-memory parallel computers. In our implementation, we divide a binary tree based on the idea of m-bridges to obtain high locality, and represent local segments as serialized arra...

The amino-terminal amino acid sequence of the pili protein from Pseudomonas aeruginosa K pili is presented. The sequence is compared with those reported by others for pilin obtained from Neisseria gonorrhoeae and Moraxella nonlique-faciens. All three sequences are highly homologous, contain only two hydrophilic residues in the first 22 positions, and contain an unusual amino acid, N-monomethylp...

Convolution surfaces generalize point-based implicit surfaces to incorporate higherdimensional skeletal elements, of which line segments can be considered the most fundamental since they can approximate curve skeletons. Existing analytical models for line-segment skeletons assumes uniform weight distributions and thus can only produce constant-radius convolution surfaces. This paper presents an...

More and more mobile objects are now equipped with sensors allowing real time monitoring of their movements. Nowadays, the data produced by these sensors can be stored in spatio-temporal databases. The main goal of this article is to perform a data mining on a huge quantity of mobile object’s positions moving in an open space in order to deduce its behaviour. New tools must be defined to ease t...
