234 Freire, JulianaPersonalizing the web using site descriptionsThe information overload on the Web has created a great need for efficient filtering mechanisms. Many sites (e.g., CNN and Quicken) address this problem by allowing a user to create personalized pages that contain only information that is of interest to the user. We propose a new approach for p...XPointer; Data extraction; Site descriptions; Personalized web pages1999
235 DeTar, CarletonWhich chiral symmetry is restored in high temperature quantum chromodynamics?Sigma models for the high temperature phase transition in quantum chromodynamics suggest that at high temperature the SU(Nf) X 3 SU(Nf) chiral symmetry becomes exact, but the anomalous axial U(1) symmetry need not be restored. In numerical lattice simulations, traditional methods for detecting symme...Chiral symmetry; Staggered fermions; Phase transitions1997-01
236 Liu, FengMagnetism in nanopatterned graphite filmUsing first-principles calculations, we show that nanopatterned graphite films (NPGFs) can exhibit magnetism in analogy to graphene-based nanostructures (GBNs). In particular, graphite films with patterned nanoscale triangular holes and channels with zigzag edges all have ferromagnetic ground state...Nanopatterned graphite; Graphite films; NPGF2008
237 Rogers, Alan R.Migration and genetic drift in human populationsIn humans and many other species, mortality is concentrated early in the life cycle, and is low during the ages of dispersal and reproduction. Yet precisely the opposite is assumed by classical population-genetics models of migration and genetic drift. We introduce a model in which population regul...Frequencies; Variance; Dynamics1986
238 Adler, Frederick R.Effects of intraspecific density-dependence on species richness and species abundance distributionsAbstract Species richness and patterns of abundance result from the interplay between niche differences, realized as intraspecific density-dependence (IDD), and so-called neutral processes that arise when species fitnesses are similar. This paper presents an extension of neutral models that incorpo...2010

240 Shirley, Peter S.; Gooch, BruceAutomatic painting with economized strokesWe present a method that takes a raster image as input and produces a painting-like image composed of strokes rather than pixels. Unlike previous automatic painting methods, we attempt to use very few brush-strokes. This is accomplished by first segmenting the image into features, finding the medial...Raster image; Painting-like image; Automatic painting methods2000
241 Thomas, Kirk R.; Capecchi, Mario R.Introduction of homologous DNA sequences into mammalian cells induces mutations in the cognate gene.Injection of homologous DNA sequences into nuclei of cultured mammalian cells induces mutations in the cognate chromosomal gene. It appears that these mutations result from incorrect repair of a heteroduplex formed between the introduced and the chromosomal sequence. This phenomenon is termed 'heter...Animals; Cell Line; Drug Resistance, Microbial; Fibroblasts; Mice; Models, Genetic; Neomycin; Plasmids1986-11-06

246 Rogers, Alan R.; Jorde, Lynn B.Ascertainment bias in estimates of average heterozygosityPopulation geneticists work with a nonrandom sample of the human genome. Conventional practice ensures that unusually variable loci are most likely to be discovered and thus included in the sample of loci. Consequently, estimates of average heterozygosity are biased upward. In what follows we descri...Bias (Epidemiology); Biometry; Heterozygote1996-05
247 Gehl, Robert W.Building a blog cabin during a financial crisis: circuits of struggle in the digital enclosureOne of the most pressing questions facing television studies is how to understand the migration of media production and consumption onto web applications which depend on user-generated content.
