Ivan Havel remembers when in the late 1970s the Czechoslovakian state police began watching his apartment. For months he had been hosting unofficial science seminars, and the police didn't like it. "It politicized me, says the soft-spoken computer scientist and brother of Czechoslovakian president Vaclav Havel. "The police would check the people who came and ask them to identify 'themselves.

Water quantity and quality joint operation is a new mode in the present dams' operation research. It has become a hot topic in governmental efforts toward integrated basin improvement. This paper coupled a water quantity and quality joint operation model (QCmode) and genetic algorithm with Soil and Water Assessment Tool (SWAT). Together, these tools were used to explore a reasonable operation o...

This paper compares ve deenitions of data integrity, and shows how they can be ordered in an increasingly restrictive sequence. The most general of these, due to Courtney and Ware 6], is based on the concept of expectation of data quality: data has integrity to the extent that its quality meets, or exceeds, the quality requirements that users expect of it. This deenition incorporates liveness r...

Cyclic unsaturated ketone frameworks, which are obtained as the dearomatized products of phenols and their derivatives, valuable to synthesis complex molecules also contribute generation that can be readily employed for further transformations. Herein, use hypervalent iodine compounds access enantioenriched through direct stepwise dearomatization reactions have been elaborated. More information...
