Multichannel seismic-reflection data show that the Victoria Land-basin, unlike other sedimentary basins in the Ross Sea, includes a rift-depression 15 to 25 kilometers wide that parallels the Transantarctic Mountains and contains up to 12 kilometers of possible Paleozoic to Holocene age sedimentary rocks. An unconformity separates the previously identified(More)
The Commission on Spatial Data Standards of the International Cartographic Association (ICA) is working on defining formal models and technical characteristics of Spatial Data Infrastructures (SDI). To date, this work has been restricted to the Enterprise and Information Viewpoints from the ISO Reference Model for Open Distributed Processing (RM-ODP)(More)
Comparison of experimental and computational protein folding studies can be difficult because of differences in structural resolution. Isotope-edited infrared spectroscopy offers a direct measure of structural changes involved in protein folding at the single-residue level. Here we demonstrate the increased resolution of site-specific infrared probes to the(More)
International Cartographic Association (ICA) is working on defining models of spatial data infrastructures (SDI). SDI models from the enterprise and information viewpoints of the Reference Model for Open Distributed Processing (RM-ODP) have already been presented. Our model from the computational viewpoint identifies the main computational objects of an SDI(More)
Online social spaces have become very popular in the past couple of decades. With the great numbers of users in the online environments it becomes obvious that the human factor plays an important role in the social structure of such environments. In online virtual worlds such as Second Life one may encounter not only civil, but even criminal offenses such(More)
The high degree of complexity of macromolecular structure is extremely difficult for students to process. Students struggle to translate the simplified two-dimensional representations commonly used in biochemistry instruction to three-dimensional aspects crucial in understanding structure-property relationships. We designed four different physical models to(More)
Early in 2007, the CSIR conducted an experiment to track the cellular telephones of a small group of people as they moved to and from an event, to test the viability of using such tracking to provide the participants with useful traffic information. This project raised a number of ethical issues, which prompted this paper and which we discuss here. These(More)
Conventionally in formal concept analysis (FCA), concept stability is preferred in the lattice, because instability (i.e. low stability) represents noise that clouds the analysis of the data. However, high concept stability means that there are many objects with the same intent and many attributes with the same extent, which could be interpreted as a high(More)
