Stable expression of a recombinant human antinucleosome antibody to investigate relationships between antibody sequence, binding properties, and pathogenicity
No full textWhen purified under rigorous conditions, some murine anti-double-stranded-DNA (anti-dsDNA) antibodies actually bind chromatin rather than dsDNA. This suggests that they may actually be antinucleosome antibodies that only appear to bind dsDNA when they are incompletely dissociated from nucleosomes. Experiments in murine models suggest that antibody - nucleosome complexes may play a crucial role in the pathogenesis of glomerulonephritis in systemic lupus erythematosus. Some human monoclonal anti- DNA antibodies are pathogenic when administered to mice with severe combined immunodeficiency (SCID). Our objective was to achieve stable expression of sequence-altered variants of one such antibody, B3, in Chinese hamster ovary (CHO) cells. Purified antibodies secreted by these cells were tested to investigate whether B3 is actually an antinucleosome antibody
Information visualization on interactive tabletops in work vs. public settings
No full textDigital tabletop displays and other large interactive displays have recently become more affordable and commonplace. Due to their benefits for supporting collaborative work—when compared to current desktop-based setups—they will likely be integrated in tomorrow’s work and learning environments. In these environments the exploration of information is a common task. We describe design considerations that focus on digital tabletop collaborative visualization environments. We focus on two types of interfaces: those for information exploration and data analysis in the context of workplaces, and those for more casual information exploration in public settings such as museums. We contrast design considerations for both environments and outline differences and commonalities between them
Studying direct-touch interaction for 2D flow visualization
No full textTraditionally, scientific visualization research concentrates on the development and improvement of interactive techniques to support expert data analysis. While many scientific visualization tools have been developed for desktop environments and individual use, scenarios that go beyond mouse and keyboard interaction have received considerably less attention. We present a study that investigates how large-display direct-touch interaction affects data exploration and insight generation among groups of nonexperts exploring 2D vector data. In this study, pairs of participants used interaction techniques to customize and explore 2D vector visualizations and collaboratively discussed the process to develop their own understanding of the data sets

Review of \u3ci\u3eThe Destruction of the Bison: An Environmental History, 1750-1920\u3c/i\u3e By Andrew C. Isenberg
No full textThe transformation of the Great Plains through the introduction of new plants and animals and the restriction or near-eradication of native species is one of the great environmental events of the past two hundred years. In The Destruction of the Bison, Andrew C. Isenberg describes the nineteenth-century decline and near-extinction of one species and early twentieth-century attempts to regenerate and reintroduce it to its former habitat. Isenberg deals with cultural, ecological, and economic factors, stressing the volatile nature of the Plains and declaring that the destruction of the bison was not merely the result of human agency, but the consequence of the interaction of human societies with a dynamic environment.
The bison\u27s digestive system made efficient use of nutritious short grasses; its size discouraged predators. Under favorable conditions, the grassland may have supported as many as thirty millions of these ruminants. By the early 1800s, American Indians on the margins of the Plains had acquired horses and moved into the bison\u27s range, bringing pressure on the herds both by hunting and competing for forage. Euro-Americans and the steam engine soon entered the equation, with riverboats bearing away hundreds of thousands of robes traded by Indians and, in the 1870s and \u2780s, railroads carrying the hide hunters\u27 harvest of raw skins east. Having all but finished off the bison, white Americans adopted two distinct attitudes towards the remnant: a handful of easterners valorized the animal as a symbol of the nation\u27s virile, expansionist past, while western ranchers bred it as a tourist attraction and sold its meat.
Besides human factors-most conspicuously industrial capitalism, which enmeshed Indians in the robe trade decades before commercial tanners discovered a way to turn raw bison hides into leather-Isenberg pays attention to the Plains climate and to what evidence there is of disease among the bison herds. His sources are unexceptionable for the most part, although in the chapter about hide hunters he relies too freely on reminiscences and popular articles, one of which apparently asserted that a .50-calibre rifle could fire slugs weighing up to one pound. One ounce, give or take a tiny fraction, was more like it. Minor flaws aside, The Destruction of the Bison is certain to stimulate discussion of its author\u27s conclusions and likely to remain a standard work of environmental history for years to come

Transport of Solar Wind Fluctuations: A Two-Component Model
No full textWe present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece. Quantities solved for include the energy, cross helicity, and characteristic transverse length scale of each component, plus the proton temperature. The development of the model is outlined and numerical solutions are compared with spacecraft observations. Compared to previous single-component models, this new model incorporates a more physically realistic treatment of fluctuations induced by pickup ions and yields improved agreement with observed values of the correlation length, while maintaining good observational accord with the energy, cross helicity, and temperature
