We have shown that ouabain activates Src, resulting in subsequent tyrosine phosphorylation of multiple effectors. Here, we tested if the Na+/K+-ATPase and Src can form a functional signaling complex. In LLC-PK1 cells the Na+/K+-ATPase and Src colocalized in the plasma membrane. Fluorescence resonance energy transfer analysis indicated that both proteins(More)
The ®eld of Adaptive Interfaces has been an active area of research for over 10 years. While there have been great advances, unresolved issues remain. The paper presents a reappraisal of adaptive interfaces with an eye toward addressing these issues using biologically inspired methods. We ®rst de®ne a general and theoretical model of adaptive interfaces(More)

Abstract Although markets for network goods and services such as video games, DVD-players, or PC hard-and software have since long become a standard topic of economic research and textbooks, our understanding of their(More)
Sentiment analysis has undergone a shift from document-level analysis, where labels expresses the sentiment of a whole document or whole sentence, to subsentential approaches, which assess the contribution of individual phrases, in particular including the composition of sentiment terms and phrases such as negators and intensifiers. Starting from a small(More)

The first silenolates with exocyclic structures [(Me 3 Si) 2 Si(Si 2 Me 4) 2 SiC(R)O] − K + (2a: R = 1-adamantyl; 2b: mesityl; 2c: o-tolyl) were synthesized by the reaction of the corresponding acylcyclohexasilanes 1a−c with KOtBu. NMR spectroscopy and single-crystal X-ray diffraction analysis suggest that the aryl-substituted silenolates 2b,c exhibit(More)
