The computation of mean firing rates and correlations is intractable for large neural networks. For symmetric networks one can derive mean field approximations using the Taylor series expansion of the free energy as proposed by Plefka. In asymmetric networks, the concept of free energy is absent. Therefore, it is not immediately obvious how to extend this method to asymmetric networks. In this ...

in asymmetric conflicts, great powers often adopt coercive strategies toward weak states. this strategy is a combination of threat, and limited and warning use of force if necessary to impact the opposite's strategy choice. given that the threats of the most powerful states are more effective because the penalty for target disobedience will be more intensive, it seems that the weak states ...

T his paper investigates the gain of bilateral trade between China and U.S. in manufacturing sectors when both countries play a role in asymmetric (biased) growth of  international trade. Our model includes a special case of Biased Growth Theory in international trade. We collected labor productivity, export and import data by using classification of manufacturing industries, for U.S...

The foundations of time asymmetric quantum theory are reviewed and are applied to the construction of relativistic Gamow vectors. Relativistic Gamow vectors are obtained from the resonance pole of the S-matrix and furnish an irreducible representation of the Poincaré semigroup. They have all the properties needed to represent relativistic quasistable particles and can be used to fix the definit...
