Fluorescence resonance energy transfer (FRET) between lipid-linked donor and acceptor molecules in two apposing lipid bilayer membranes is used to resolve topographical features at an intermembrane junction. Efficient energy transfer occurs when the membranes are apposed closely, which creates an image, or footprint, that maps the contact zone and reveals nanometer-scale topographical structure...

In the history of surveying and mapping, a large volumes of topographic maps and digital elevation models have been created at various scales throughout the world. However, positional errors and geometric distortions may exist in the topographic contour maps and their derived DEMs due to inaccurate ground control and poor navigation techniques in the early years. In this paper, we present a new...

Der Begriff der Topic Map erfährt seit circa zwei Jahren eine moderate, aber deutlich wachsende Beachtung in der Fachöffentlichkeit. Viele Anwendungen zeichnen sich aber durch ihren Demonstrationscharakter aus oder sind akademischer Natur. In diesem Beitrag geht es um ein Pilotprojekt in der Luftfahrtindustrie, das der Verfasser im Rahmen seiner Tätigkeit für die Sörman Information GmbH durchge...

Information structure has been assumed to be an autonomous part of grammar for more than 100 years. It is represented as a partition of the sentence into two units, e.g., focus background, topic comment, focus topic, focus presupposition etc.1 Even though information structure is sometimes understood as textual or discourse structure, its organizational level is still defined with respect to th...

Fix a nontrivial interval X C R and let / e C1(X,X) be a chaotic mapping. We denote by Aoo (/) the set of points whose orbits do not converge to a (one-sided) asymptotically stable periodic orbit of / or to a subset of the absorbing boundary of X for /. A. We assume that / satisfies the following conditions: (1) the set of asymptotically stable periodic points for / is compact (an empty set is ...

Street networks can be visualized in various ways depending on the purpose. Here we introduce (in the present context) a new technique for visualizing the orientation of street networks in relation to complex topography. The technique is tested on the city of Sheffield, England, with a current population of about 555,500 (in 2010) and a total street number of 23,500. Using digital elevation map...

The intraparietal sulcus (IPS) region is uniquely situated at the intersection of visual, somatosensory, and auditory association cortices, ideally located for processing of multisensory attention. We examined the internal architecture of the IPS region and its connectivity to other regions in the dorsal attention and cinguloinsular networks using maximal connectivity clustering. We show with r...
