Weighted Partonomy-taxonomy Trees with Local Similarity Measures for Semantic Buyer-seller Match-making

A semantically enhanced weighted tree similarity algorithm for buyer-seller match-making is presented. First, our earlier global, structural similarity measure over (product) partonomy trees is enriched by taxonomic semantics: Inner nodes can be labeled by classes whose partial subsumption order is represented as a taxonomy tree that is used for similarity computation. In particular, the simila...

Otto Loewi

The end of the 19th century was the starting point of many discoveries in the field of the neurophysiology. At that time, only basic technical approaches were available, and new discoveries depended on few results and lots of deductions. Furthermore, the scientific community was often debating on theoretical speculations and was often divided. I have chosen to present a German neurophysiologist...

The Quantum Harmonic Otto Cycle

The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element. We compile recent studies of the quantum Otto cycle with a harmonic oscillator as a working medium. This model has the advantage that it is analytically trackable. In addition, an experimental realization has been achieved, employing a...

Otto Cohnheim--the forgotten physiologist.

Who was Otto Cohnheim? It is no exaggeration to say that he was the man who laid the foundation of our present understanding of the absorption of protein digestion products and also protein metabolism-yet he remains forgotten. This is largely because he unfortunately became, like so many others, a victim of political enthusiasm. 1978 is the 25th anniversary of his death, a fitting time to try t...
