Freire, Juliana | Designing information-preserving mapping schemes for XML | An XML-to-relational mapping scheme consists of a procedure for shredding XML documents into relational databases, a procedure for publishing databases back as documents, and a set of constraints the databases must satisfy. In previous work, we discussed two notions of information preservation for m... | Losslessness; Validation; Mapping scheme; Edge++; LILO; Lossless Inlining; Lossless Outlining; XML Schema | 2005 |

Zimmer, Zachary | Education of adult children and mortality of their elderly parents in Taiwan | Research shows an older adult's education is strongly associated with mortality. But in societies such as Taiwan, where families are highly integrated, the education of family members may be linked to survival. Such may be the case in settings where there are large gaps in levels of education acros... | Education; Mortality | 2005 |

Scarpulla, Michael | Effect of film thickness on the incorporation of Mn interstitials in Ga1-xMnxAs | We have investigated the effect of film thickness on the distribution of Mn atoms at various lattice sites in Ga1−xMnxAs thin films. We find that the growth surface acts as a sink facilitating the outdiffusion of Mn interstitials sMnId, and thus reducing its concentration in the film. The outdiffu... | Interstitials; Gallium arsenide | 2005 |

Sanchez, Thomas W. | Effectiveness of urban containment regimes in reducing exurban sprawl | During the 1990s, the exurban landscape grew faster and added more people than urban, suburban, and rural landscapes. In many respects, exurbanization is the quintessential representation of urban sprawl and the problems it poses. More than 100 metropolitan areas across the US attempt to manage exu... | Exurban; Containment; Urban sprawl | 2005 |

Gesteland, Raymond F.; Baranov, Pavel V.; Atkins, John F. | Expression levels influence ribosomal frameshifting at the tandem rare arginine codons AGG_AGG and AGA_AGA in Escherichia coli | ABSTRACT: The rare codons AGG and AGA comprise 2% and 4%, respectively, of the arginine codons of Escherichia coli K-12, and their cognate tRNAs are sparse. At tandem occurrences of either rare codon, the paucity of cognate aminoacyl tRNAs for the second codon of the pair facilitates peptidyl-tRNA... | Gene expression; Frameshifting; E. coli; Arginine codons | 2005 |
