Among the Milky Way satellites discovered in the past three years, TriangulumII has presented the most difficulty in revealing its dynamical status. Kirby et al. identified it as the most dark-matter-dominated galaxy known, with a mass-to-light ratio within the half-light radius of M L 360

The paper starts by sketching the key modes of spatial data analysis (point pattern, continuous surface, areal/lattice), and how they fit into legacy GIS data models. Based on development work with the GRASS release 5 team (GRASS 5 is GPL), status is reported for using R in the analysis of sites (point) data and for raster data, as well as using R as an intermediate analytical environment for i...

Evolution and Testing of the Lacunar Hypothesis" by Bamford and Warlow in this issue of Stroke reviews many important aspects of these unique pathologic vascular lesions. I concur with the authors' emphasis on the need to maintain homogeneity in the classification of stroke conditions, specifically lacunes. A stroke classification scheme would ideally be based on 1) risk factor profile such as ...

We survey the recent applications and developments of sieve methods related to discrete groups, especially in the case of infinite index subgroups of arithmetic groups.

Introduction: This study was conducted to evaluate the influence of chitosan Nano-gel/emulsion coating functionalized by Ziziphora clinopodioides essential oil (ZCEO) and nisin on growth inhibition of Escherichia coli O157: H7 inoculated in beef samples during 16 days in cold storage condition (4˚C). Methods: Beef sample ...

abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...

We present a novel algorithm designed to find common sub-structure features between multiple proteins with similar function but different overall fold. The algorithm is intended to run with multiple input proteins and will find multiple matching sub-structures if there are several present. Such sub-structures would be useful in the annotation of new protein structures with unknown function, esp...
