The problem of logical omniscience arises at two levels. One is the individual level, where an agent is assumed to have reasoning powers which are unrealistic. The other, equally important one, is where two or more agents are supposed to share a state of knowledge (perhaps common knowledge) which is read off from a physical situation, but which may not hold in practice. By reducing knowledge to...
Roses are among the most widely produced cut flowers, with important ornamental and economic value in flower market. In order to investigate how regulate flowering periods, negative regulator of GA biosynthesis RcSPY was cloned from Rosa chinensis ectopically expressed tobacco. The overexpression SPY4 transgenic tobacco significantly increased plant height. Antisense interference conserved SPY ...
scented rose species are very important in the genus rosa due to their use in highly-prized essential oil production and as garden roses. the fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. a comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly damask r...
In this article we present RoSeS (Really Open Simple and Efficient Syndication), a generic framework for content-based RSS feed querying and aggregation. RoSeS is based on a data-centric approach, using a combination of standard database concepts like declarative query languages, views and multiquery optimization. Users create personalized feeds by defining and composing content-based filtering...
Ring a ring of roses: Spectacular nanoscale molecular assemblies have been created by design of individual polymetallic components that are then linked together through simple reactions. These include an assembly where six octametallic rings surround a dodecametallic central ring.
Ecological adaptations to seasonal changes are often observed in the phenotypic traits of plants and animals, and these adaptations are usually expressed through the production of different biochemical end products. In this study, ecological adaptations are observed in a biochemical pathway without alteration of the end products. We present an alternative principal pathway to the characteristic...
