While high-performance computing is a fundamental component of CyberGIS, equally important is establishing a fundamental connection between CyberGIS and the various user communities requiring it. This involves the sharing, communication, and collaboration of authoritative, relevant spatial science not only among GIS specialists within their respective organizations, but across relat-ed scientific...
A new matrix operator framework is developed to analyze results from climate modeling studies that employ numerical water tracers (WTs), which track the movement of water in the aerial hydrological cycle from evaporation to precipitation. Model WT output is related to the fundamental equation of hydrology, and the moisture flux...
The Gulf Stream is a major conduit of warm surface water from the tropics to the subpolar North Atlantic. Here we observe and simulate a submesoscale (<20 km) mechanism by which the Gulf Stream exchanges water with subpolar water to the north. Along isopycnals, the front has a sharp compensated...
Recent trends in librarianship point to themes of crafters, artisans, and makers in library spaces. The American Library Association's Center for the Future of Libraries includes the Maker Movement as one of its trends. Librarians can support these makers and entrepreneurs by thinking of libraries as a place to create...
Reservoirs can have both positive and negative effects on differing fish species depending on the species concerned and reservoir morphology, flow regime, and basin location. We assessed the influence of limnological zones on the ichthyofauna of three large Neotropical reservoirs in two different river basins. We sampled fish through use...
Recent studies hypothesize that some submarine slides fail via pressure-driven slow-slip deformation. To test this hypothesis, this study derives pore pressures in failed and adjacent unfailed deep marine sediments by integrating rock physics models, physical property measurements on recovered sediment core, and wireline logs. Two drill sites (U1394 and U1399)...
The particle size distribution (PSD) is a critical aspect of the oceanic ecosystem. Local variability in the PSD can be indicative of shifts in microbial community structure and reveal patterns in cell growth and loss. The PSD also plays a central role in particle export by influencing settling speed. Satellite-based...
The leading edge of the ENE-trending Himalayan thrust front in Pakistan exhibits along-strike changes in deformational style, ranging from fault-bend to fault-propagation folds. Although the structural geometry is very gently deformed throughout the Salt Range, it becomes progressively more complex to the east as the leading edge of the emergent...

Ocean Solutions, Earth Solutions gathers the insights of more than 50 ocean and coastal science researchers exploring ocean components and their relationships, patterns, and trends over time and space. The book's 16 chapters feature geographic information system (GIS) best practices and include additional...
Directing feature films in the GDR was largely a male-dominated profession. One of the few female directors was Iris Gusner, whose films explored issues working GDR women faced in their everyday lives. A close reading of her 1984 feature film Kaskade Rückwärts, in particular the focus on sound and on...
Coral reefs are in decline worldwide, and land-derived sources of pollution, including sewage, are a major force driving that deterioration. This review presents evidence that sewage discharge occurs in waters surrounding at least 104 of 112 reef geographies. Studies often refer to sewage as a single stressor. However, we show...
Small chemicals like drugs tend to bind to proteins via noncovalent bonds, e.g. hydrogen bonds, salt bridges or electrostatic interactions. Some chemicals interact with other molecules than the actual target ligand, representing so-called ‘off-target' activities of drugs. Such interactions are a main cause of adverse side effects to drugs and...
Exposing research data from traditional repository systems such as DSpace in Linked Data has numerous benefits such as increasing visibility, prompting open access, and interlinking datasets with elements such as authors. For a successful implementation, it is crucial to preserve object structure (e.g., hierarchical and related) in Linked Data in...
The National Institutes of Health (NIH) Public Access Policy that began in 2008 requires that final peer-reviewed journal manuscripts sponsored by the agency are freely available in PubMed Central. NIH requires that researchers who apply for grants must include a PMC reference number (PMCID) when citing their papers that were...
Satellite‐derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf‐open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well‐defined seasonal pattern of SSS during...
In opening our eyes to the unseen wonders of the ocean Jacques Cousteau is thought to have said, “People protect what they love.” A variation, perhaps, on the words of the Senegalese poet and naturalist Baba Dioum: “In the end, we will conserve only what we love. We will love...
A coupled biophysical model is used to examine the impact of the great Arctic cyclone
of early August 2012 on the marine planktonic ecosystem in the Pacific sector of the Arctic
Ocean (PSA). Model results indicate that the cyclone influences the marine planktonic
ecosystem by enhancing productivity on the shelves...
OBJECTIVE: Pharmacokinetic interactions exist between combined
oral contraceptives and protease inhibitors (PI). However, such
information is lacking for progestin-only oral contraception. We
sought to define the steady-state pharmacokinetic interaction between
norethindrone (NET) and PI in HIV-infected women.
METHODS AND DESIGN: We conducted an open-label, prospective,
nonrandomized trial to characterize the...
The increase in atmospheric concentrations of water vapor with global warming is a large positive feedback in the climate system. Thus, even relatively small errors in its magnitude can lead to large uncertainties in predicting climate response to anthropogenic forcing. This study incorporates observed variability of water vapor over 2002–2009...
Adsorbed molecules are involved in many reactions on solid surfaces that are of great technological
importance. As such, there has been tremendous effort worldwide to learn how to theoretically
predict rates for reactions involving adsorbed molecules. Theoretical calculations of rate constants
require knowing both their activation energy and prefactor. Recent...
Magnesiothermic reduction can directly convert SiO₂ into Si nanostructures. Despite intense efforts, efficient fabrication of highly nanoporous silicon by Mg still remains a significant challenge due to the exothermic reaction nature. By employing table salt (NaCl) as a heat scavenger for the magnesiothermic reduction, we demonstrate an effective route to...
The sum of the Holevo quantity (that bounds the capacity of quantum channels to transmit classical information about an observable) and the quantum discord (a measure of the quantumness of correlations of that observable) yields an observable-independent total given by the quantum mutual information. This split naturally delineates information about...
Measurement of a quantum system - the process by which an observer gathers information about it - provides a link between the quantum and classical worlds. The nature of this process is the central issue for attempts to reconcile quantum and classical descriptions of physical processes. Here, we show that...
Polyhalogenated quinones are a class of carcinogenic intermediates. We found recently that the highly reactive and biologically/environmentally important center [dot]OH can be produced by polyhalogenated quinones and H₂O₂ independent of transition metal ions. However, it is not clear whether this unusual metal-independent center dot OH producing system can induce potent...
Characterization and biological roles of the peroxisome proliferator-activated receptor (PPAR) isotypes are well known in monogastrics, but not in ruminants. However, a wealth of information has accumulated in little more than a decade on ruminant PPARs including isotype tissue distribution, response to synthetic and natural agonists, gene targets, and factors...
We quantified the patterns in macroinvertebrate assemblages and their
associated environmental gradients from 457 least-disturbed wadeable
stream sites across the 48 contiguous United States sampled as part
of US EPA’s National Wadeable Stream Assessment. The majority of the
variation in assemblage composition at the finest taxonomic resolution
was related to...
Three-dimensional symmetric tensor fields have a wide range of applications in solid and fluid mechanics. Recent advances in the topological analysis of 3D symmetric tensor fields focus on the local behaviors of tensor fields at degenerate points, which usually form curves. In this paper, we make a number of observations...
Global sustainability goals have led to the development of the green building movement. The Green
Building Program, stemming from the movement, has had unprecedented success as it provides a quantifi able
metric to people’s efforts towards sustainable development. Sustainable development and green buildings are often
used interchangeably. Although, sustainable development...
The down‐regulation of dominant oncogenes, including C‐MYC, in tumor cells often leads to the induction of
senescence via mechanisms that are not completely identified. In the current study, we demonstrate that MYC‐depleted
melanoma cells undergo extensive DNA damage that is caused by the underexpression of thymidylate synthase (TS) and
ribonucleotide...
We study an Ising chain undergoing a quantum phase transition in a quantum magnetic field. Such a field can be emulated by coupling the chain to a central spin initially in a superposition state. We show that - by adiabatically driving such a system - one can prepare a quantum...
Forest ecosystem dynamics emerges from nonlinear interactions between adaptive biotic agents (i.e., individual trees) and their relationship with a spatially and temporally heterogeneous abiotic environment. Understanding and predicting the dynamics resulting from these complex interactions is crucial for the sustainable stewardship of ecosystems, particularly in the context of rapidly changing...

New seafloor mapping and sampling demonstrates that the eruption of the high-Ca boninites is clearly associated with rifting of the northern Tonga ridge and the northern Lau Basin at the northern termination of the Tonga Trench. There is very strong evidence for OIB plume related mantle sources involved in the...
In this paper, we describe a fusion approach to finding opinionated blog postings. Our approach to opinion blog retrieval consisted of first applying traditional IR methods to retrieve on-topic blogs and then boosting the ranks of opinionated blogs based on combined opinion scores generated by multiple assessment methods. Our opinion...
In TREC-2007, Indiana University‟s WIDIT Lab1 participated in the Blog track‟s opinion task and the polarity subtask. For the opinion task, whose goal is to "uncover the public sentiment towards a given entity/target", we focused on combining multiple sources of evidence to detect opinionated blog postings. Since detecting opinionated blogs...
Web Information Discovery Tool (WIDIT) Laboratory at the Indiana University School of Library, whose basic approach to combine multiple methods as well as to leverage multiple sources of evidence, participated in 2005 Text Retrieval Conference’s Hard track (HARD-2005) to investigate methods of effectively dealing with HARD topics by exploring a...
