Analysis of the Aspergillus fumigatus Proteome Reveals Metabolic Changes and the Activation of the Pseurotin A Biosynthesis Gene Cluster in Response to Hypoxia

Martin Vödisch, Kirstin Scherlach, Robert Winkler, Christian Hertweck, Hans-Peter Braun, Martin Roth, Hubertus Haas, Ernst R. Werner, Axel A. Brakhage & Olaf Kniemeyer
The mold Aspergillus fumigatus is the most important airborne fungal pathogen. Adaptation to hypoxia represents an important virulence attribute for A. fumigatus. Therefore, we aimed at obtaining a comprehensive overview about this process on the proteome level. To ensure highly reproducible growth conditions, an oxygen-controlled, glucose-limited chemostat cultivation was established. Two-dimensional gel electrophoresis analysis of mycelial and mitochondrial proteins as well as two-dimensional Blue Native/SDS-gel separation of mitochondrial membrane proteins led to the identification of...

Gated communities: perspectives on privatized spaces: review essay

Matthew Durington
Private Cities: Global and Local Perspectives (2006) and Gated Communities (2006) continue a trend in urban studies that focus on recent manifestations of these developments in a variety of global locales. As the editors of Private Cities note, ‘there is hardly another form of urban development that has received so much public attention since the late 1990s as privately organized and secured housing developments’ (Glasze et al., 2006: 1). The two volumes are a fantastic...

Lifetime degradation mechanism in boron-doped Czochralski silicon

V.V. Voronkov, R. Falster, A.V. Batunina, D. MacDonald, K. Bothe & J. Schmidt
The recombination centre that emerges in boron- and oxygen-containing silicon was thought to be a complex of a substitutional boron atom Bs and an oxygen dimer O2. However in material co-doped with boron and phosphorus, the degradation parameters were reported to correlate with the hole concentration p rather than with the boron concentration. In the present work, the temperature dependence of the Hall Effect was measured in co-doped and reference samples and the concentrations of...

An Optimization Approach for Semantic-based XML Schema Matching

Jaewook Kim, Yun Peng, Nenad Ivezik & Junho Shin
We propose a novel solution for semantic-based XML schema matching, taking a mathematical programming approach. This method identifies the globally optimal solution for the problem of matching leaf nodes between two XML schema trees by reducing the tree-to-tree matching problem to simpler problems of path-to-path, node-to-node, and word-to-word matching. We formulate these matching problems as maximum-weighted bipartite graph matching problems with different constraints, which are solved by different mathematical programming techniques, including integer programming and...

A Semantic Approach to Automate Service Management in the Cloud

Karuna Pande Joshi, Tim Finin & Yelena Yesha
Virtualized service models are now emerging and re-defining the way information technology is delivered. Managing these services efficiently over the cloud is an open challenge. In this paper, we describe an integrated methodology for the lifecycle of IT services delivered on the cloud. We have divided the IT service lifecycle into five phases of requirements, discovery, nego-tiation, composition, and consumption. We detail each phase and list the high level ontologies that we have developed for...

Privacy Preservation in Context Aware Geosocial Networking Applications

Pramod Jagtap, Anupam Joshi, Tim Finin & Laura Zavala
Recent years have seen a confluence of two major trends - the increase of mobile devices such as smart phones as the primary access point to networked information and the rise of social media platforms that connect people. Their convergence supports the emergence of a new class of context-aware geo-social networking applications. While existing systems focus mostly on location, our work centers on models for representing and reasoning about a more inclusive and higher-level notion...
