In this paper, we propose an approach for content determination and surface generation of answers in a question-answering system on the web. The content determination is based on a coherence rate which takes into account coherence with other potential answers. Answer generation is made through the use of classical techniques and templates and is based on a certainty degree.

This paper argues for a game-theoretic approach to content determination that uses text-type specific strategies in order to determine the optimal content for various user types. By means of content determination for the description of numerical data the benefits of a game-theoretic treatment of content determination are outlined.

Eighty to ninety percent of vegetative cells of Saccharomyces cerevisiae DCL 740 incubated in KCl-acetate medium form asci, the majority of which are four-spored. Ascospores are visible in asci after about 24 hr, and spore formation is complete after about 48 hr. The dry weight of the cells increases by about 75% during 48 hr of incubation, while the lipid content of the cells increases by a fa...

Voriconazole (UK-109,496) is a novel triazole derivative with potent broad-spectrum activity against various fungi, including some that are inherently resistant to fluconazole, such as Candida krusei. In this study we compared the effect of subinhibitory concentrations of voriconazole and fluconazole on sterol biosynthesis of fluconazole-resistant and -susceptible Candida albicans strains, as w...

objective(s):isoprenoid biosynthesis is a key metabolic pathway to produce a wide variety of biomolecules such as cholesterol and carotenoids, which target cell membranes. on the other hand, it has been reported that statins known as inhibitors of isoprenoid biosynthesis and cholesterol lowering agents, may have a direct antimicrobial effect on the some bacteria. the exact action of statins in ...

Previous studies have shown that antibodies to cubulin, a receptor on the yolk sac that binds high density lipoproteins (HDL) and cobalamin, induce fetal abnormalities. Mice with markedly low concentrations of plasma HDL-cholesterol (HDL-C) give birth to healthy pups, however. To establish whether maternal HDL-C has a role in fetal development, sterol metabolism was studied in the fetus and ext...

Miltefosine (hexadecylphosphocholine [HePC]) is the first orally active drug approved for the treatment of visceral leishmaniasis. In order to investigate the biochemical modifications occurring in HePC-resistant (HePC-R) Leishmania donovani promastigotes, taking into account the lipid nature of HePC, we investigated their fatty acid and sterol metabolisms. We found that the content of unsatura...

Background and Purpose: The frequency of opportunistic fungal infections in immunocompromised patients, especially by Candida species, has sharply increased in the last few decades. The objective of this study was to analyse the ergosterol content and gene expression profiling of clinical isolates of fluconazole resistant Candida albicans. Materials and Methods: Sixty clinical samples were ide...

3-Hydroxy-3-methylglutaryl-coenzyme A synthase (HMGS) in the mevalonate (MVA) pathway generates isoprenoids including phytosterols. Dietary phytosterols are important because they can lower blood cholesterol levels. Previously, the overexpression of Brassica juncea wild-type (wt) and mutant (S359A) BjHMGS1 in Arabidopsis up-regulated several genes in sterol biosynthesis and increased sterol con...

abstract: in this study the non-saponifiable matter of oils extracted from nine varieties of sunflower seed were subjected a series of chemical tests. the non-saponifiable matters were fractionated into a number of chemical classes of compounds namely sterols, 4 methyl sterols, triterpene alcohols, tocopherols and hydrocarbons. the two major and important classes of compounds consisting of ster...
