We explain excess volatility, short-term momentum and long-term reversal of asset prices by a repeated game version of Keynes’ beauty contest. In every period the players can either place a buy or sell order on the asset market. The actual price movement is determined by average market orders and noise. It is common knowledge that the noise process is an exogenous random walk. Our model explain...

Later I learned that Salk's efforts were built on pioneering work of many others, including John Enders, Thomas Weller and Frederick Robbins (Nobelists, 1954), and David Bodian, who pioneered studies of polio patho...

Kaon pair production in proton-proton collisions at COSY-ANKE

The near-threshold production of kaon-pairs has been investigated in protonproton collisions at Cooler Synchrotron (COSY)at Forschungszentrum Jülich. In the pp → ppKK reaction, the invariant mass distributions of Kp, Kpp, and KK indicate the presence of both Kp and KK final state interactions. Total cross sections for pp → ppφ reaction have been determined at excess energies ε of 18.5, 34.5, an...

The application of logic-based learning algorithms in real-world domains, such as robotics, requires extensive data engineering, including the transformation of numerical tabular representations of real-world data to logic-based representations, feature and concept selection, the generation of the respective descriptions, and the composition of training and test sets, which meet the requirement...
