-UTCE is a platform for ultrametric tree construction and tree evaluation. Phylogenetic tree can be used by biologists to observe the relationship between species, and the ultrametric tree is a popular model which is assumed that the rate of evolution is constant. UPGMA is one of well-know ultrametric tree constructing algorithm. However, UPGMA is a heuristic algorithm and can not guarantee the...

Assessment of genetic diversity and population structure of germplasm collections plays a critical role in supporting conservation and crop genetic enhancement strategies. We used a cultivated lentil (Lens culinaris Medik.) collection consisting of 352 accessions originating from 54 diverse countries to estimate genetic diversity and genetic structure using 1194 polymorphic single nucleotide po...

As the gap between memory and processor performance continues to widen, it becomes increasingly important to exploit cache memory e ectively. Both hardware and software approaches can be explored to optimize cache performance. Hardware designers focus on cache organization issues, including replacement policy, associativity, line size and the resulting cache access time. Software writers use va...

INTRODUCTION We conducted this study to evaluate the feasibility of implementing an internet-linked handheld computer procedure logging system in a critical care training program. METHODS Subspecialty trainees in the Interdepartmental Division of Critical Care at the University of Toronto received and were trained in the use of Palm handheld computers loaded with a customized program for logg...

Remote Procedure Call (RPC) is a simple yet powerful primitive for communication and synchronization between distributed processes. A problem with RPC is the fact that it tends to decrease the amount of parallelism in the application, due to its synchronous nature. This paper shows how light-weight processes can be used to circumvent this problem. The combination of blocking RPC calls and light...

1 Introduction Logic made a major step in 1879, when Gottlob Frege published his 'Begriffss-chrift, eine der arithmetischen nachgebildete Formelsprache des reinen Denkens', see [26]. In this paper, which marks the start of modern logic, Frege introduced a formal language, (which he called Begriffsschrift), in which mathematical statements can be formally stated, and also formally proven. (witho...

This paper focuses on the problem of calibration from a single view and a map of a scene. This situation arises quite often when modelling urban scenes, e.g. for augmented reality purposes. We show how some scenes constraints can be used to achieve a calibration like procedure. An example excerpted from a sequence of pictures for which selfcalibration-like techniques consistently fail illustrat...
