Humans have always done nonmonotonic reasoning, but rigorous monotonic reasoning in reaching given conclusions has been deservedly more respected and admired. Euclid contains the first extended monotonically reasoned text available to a large public. I suspect that even Euclid did nonmonotonic reasoning in arguing for the postulates. It is unfortunate that the rigorous monotonic reasoning of Eu...

(Received for publication, July 21, 1952) Many histological studies1),2),3) on the innervation of mammalian tongues have been reported and praiseworthy results achieved histherto, but much seems yet left unexplored, and in particular, many questions are still waiting solution in connection with dog tongue. Recently, much licht has been thrown on the subject of innervation of human tongue by the...

People who have gout may contend with an increased risk of type 2 diabetes, and women seem more vulnerable than men, according to a large population-based study. The researchers at Harvard Medical School analyzed data from gout patients, and from those without the disease, in the United Kingdom's Health Improvement Network (THIN) database. They found a higher incidence of type 2 diabetes among ...

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.
