This paper describes how a concept lattice that represents semantic relations (synonymy, hyponymy, hypernymy) in a set of words can be used for semantic matching. This kind of concept lattice is the result of the formal concept analysis technique used for determining semantic relations in a set of words extracted from a monolingual dictionary. It is shown how relations between concepts can be m...

*Correspondence: H. Peter Linder, Institute of Systematic Botany, University of Zurich, Zollikerstrasse 107, CH-8008 Zurich, Switzerland e-mail: [email protected] Sub-Saharan Africa includes some 45,000 plant species. The spatial patterns of this diversity have been well explored. We can group the species into a set of biogeographical regions (largely co-incident with regions defined ...

The isolation rate of Streptococcus pneumoniae in sputum cultures from patients with pneumococcal pneumonia is low. An investigation was made to determine whether this low yield might be due to loss of pneumocci and/or overgrowth by pharyngeal flora before the specimen is plated. Pneumococcal survival times and pharyngeal overgrowth at 4 degrees C and at room temperature were determined in sput...

The paper explores the possibility of performing temporal projection in the “Digital Aristotle” reasoning system. In particular, it investigates the relationship between two methods for computing trajectories of dynamic systems: a first method using action languages and the answer set semantics, and a second method using the object-oriented declarative language Flora-2. The former method is sou...

We define logic programs with defaults and argumentation theories, a new framework that unifies most of the earlier proposals for defeasible reasoning in logic programming. We present a model-theoretic semantics and study its reducibility and well-behavior properties. We use the framework as an elegant and flexible foundation to extend and improve upon Generalized Courteous Logic Programs (GCLP...

The present paper is an overview of state the art in plant conservation Mediterranean-type Ecosystems (MTEs), highlighting current studies and neglected topics. A review literature dealing with this issue a general analysis results was performed, delving into relevant biology main topics considered were: 1) reproductive genetic conservation, 2) threat factors effects global change, 3) evaluatio...

The nature and magnitude of fluid and electrolyte loss into the small intestine were defined by the marker perfusion technique in patients with acute undifferentiated diarrhea (AUD) in the tropics. The patients were divided into two groups according to their small bowel bacteriologic findings, namely those with a predominant Escherichia coli flora and those with a mixed flora. 11 normal subject...

Obesity is currently a pandemic of worldwide proportions affecting millions of people. Recent studies have proposed the hypothesis that mechanisms not directly related to the human genome could be involved in the genesis of obesity, due to the fact that, when a population undergoes the same nutritional stress, not all individuals present weight gain related to the diet or become hyperglycemic. ...

The aim of this study was to compare the significance of the intestinal hydrolysis of prenylated flavonoids in Herba Epimedii by an intestinal enzyme and flora. Flavonoids were incubated at 37 °C with rat intestinal enzyme and intestinal flora. HPLC-UV was used to calculate the metabolic rates of the parent drug in the incubation and LC/MS/MS was used to determine the chemical structures of met...

Background. Bacterial vaginosis (BV) is associated with increased risk of obstetrical and gynecologic complications and acquisition of sexually transmitted diseases. Despite this, very little is known about the pathogenesis of this disease. Methods. Interleukin (lL)-II3, tumor necrosis factor-a, IL-6, and IL-8 concentrations in vaginal wash and serum samples from women with normal flora, interm...
