This paper investigates the use of stemming for classification of Dutch (email) texts. We introduce a stemmer, which combines dictionary lookup (implemented efficiently as a finite state automaton) with a rule-based backup strategy and show that it outperforms the Dutch Porter stemmer in terms of accuracy, while not being substantially slower. For text classification, the most important propert...

T HE THOROUGH and oft-quoted experiments of Porter (I) were designed to determine the presence or absence of crossing connections between the descending inspiratory reticulospinal fibers of one side and the phrenic motor nuclei of the opposite side. In demonstrating the existence of such connections, Porter repeated an observation which had been made previously (z-4) and formulated an hypothesi...

With large number of datasets now available through the Web, data-sharing ecosystems such as the Web Observatory have emerged. The Web Observatory provides an active decentralised ecosystem for datasets and applications based on a number Web Observatory sites, each of which can run in a different administrative domain. On a Web Observatory site users can publish and securely access datasets acr...

PURPOSE This study compared the effectiveness of 2 nasal hoods (Porter/Brown and Accutron) in reducing waste nitrous oxide gas during conscious sedation for routine pediatric dental treatment. METHODS Thirty children, ages 3 to 8 years (mean=5.4 +/- 1.2 years), participated in this study. Fifteen randomly selected children started with the Porter/Brown mask, which was then switched to the Acc...

Listeria monocytogenes is a pathogenic bacterium that can grow at low temperatures and elevated osmolarity. The organism survives these stresses by the intracellular accumulation of osmolytes: low-molecular-weight organic compounds which exert a counterbalancing force. The primary osmolyte in L. monocytogenes is glycine betaine, which is accumulated from the environment via two transport system...

Mitochondrial dysfunction has been implicated in a variety of human diseases, including cancer and neurodegenerative disorders. Effective medical therapies for such diseases will ultimately require the targeted delivery of therapeutic agents to mitochondria. This will likely be achieved through innovations in the areas of the nanotechnology of intracellular trafficking. Mitochondrial delivery s...

Economic geography in an era of global competition poses a paradox. In theory, location should no longer be a source of competitive advantage. Open global markets, rapid transportation, and high-speed communications should allow any company to source any thing from any place at any time. But in practice, Michael Porter demonstrates, location remains central to competition. Today's economic map ...
