Ontology Learning (OL) is the computational task of generating a knowledge base in the form of an ontology given an unstructured corpus whose content is in natural language (NL). Several works can be found in this area most of which are limited to statistical and lexico-syntactic pattern matching based techniques (Light-Weight OL). These techniques do not lead to very accurate learning mostly b...

Array-OL, developed by Thomson Marconi Sonar, is a programming language dedicated to signal processing. An Array-OL program specifies the dependencies between array elements produced and consumed by tasks. In particular, temporal dependencies may be specified by referencing elements that belong to an infinite dimension of an array. A basic compilation strategy of Array-OL on a workstation has b...

1. Pseudomonas sp. N.C.I.B. 8858 grew well on Dand L-1-aminopropan-2-ol and on aminoacetone. 2. Cell-free extracts possessed high activities of inducibly formed L1-aminopropan-2-ol-NAD+ oxidoreductase, amino alcohol-ATP phosphotransferase, DL-1-aminopropan-2-ol 0-phosphate phospho-lyase and aldehyde-NAD+ oxidoreductase, but no 1-aminopropan-2-ol racemase or D-I-aminopropan-2-ol-NAD+ oxidoreduct...

as mystics make relationships to god in different ways, they consider different aspects of his (god) characters. in this article, it is tried to verify distinct ways of mystics, relation to allah according to their conscience sentience (receipt) of gods traits (specifications). the main purpose of this article is surveying mystics’s relations and their inference to allah based on holly quran an...

Lithocholate (LC) (10-300 microM) in physiological solution is sensed by vascular myocyte large conductance, calcium- and voltage-gated potassium (BK) channel beta(1) accessory subunits, leading to channel activation and arterial dilation. However, the structural features in steroid and target that determine LC action are unknown. We tested LC and close analogs on BK channel (pore-forming cbv1+...

An homogenate of rat liver which was capable of converting 2-3H-lanosta-8,24-dien-3fl-ol to 2-3H-cholest-5-en-3/3-ol failed to convert 2-3H-9, 19-cyclolanost-24-en-30-01 to 2-3Hcholest-5-en-3/3-01. However, both substrates underwent reduction at C-24,25. 2-3H-9, 19-Cyclolanost-24-en-3/?-01 was not converted to 2-3H-lanosta-8,24-dien-3P-ol. Both the presence and biosynthesis (from 2-14C-mevalona...

Terpinen-4-ol is a monoterpenoid alcohol and component of the essential oils of several aromatic plants. Similarly to terpinen-4-ol, other monoterpenoid alcohols have shown anticonvulsant activity in convulsion animal models. The present study aimed to investigate the anticonvulsant activity of terpinen-4-ol. Treatment of mice with terpinen-4-ol (200 mg/kg) caused a significant decrease in the ...

Oligodendrocyte (OL) development relies on many extracellular cues, most of which are secreted cytokines from neighboring neural cells. Although it is generally accepted that both astrocytes and microglia are beneficial for OL development, there is a lack of understanding regarding whether astrocytes and microglia play similar or distinct roles. The current study examined the effects of astrocy...

BACKGROUND AND AIM: Oral leukoplakia (OL) is a common premalignant lesion. The possible benefits of specific interventions in preventing a malignant transformation of OL are not well understood. This review assesses different invasive treatment techniques for OL and evaluate the optimal treatment possibilities.METHODS: A Medline (PubMed) search was conducted and heterogeneity between the studie...
