We determine the magnetic-field dependence of the pseudogap closing temperature T* within a precursor superconductivity scenario. Detailed calculations with an anisotropic lattice model with d-wave superconductivity account for a recently determined experimental relation in BSCCO between the pseudogap closing field and the pseudogap temperature at zero field, as well as for the weak initial dep...

The thermodynamical potential of relativistic plasmas with gauge interaction can be consistently resummed in terms of HTL propagators, which is, without being restricted to it, exemplified for the case of hot QED. The nonperturbative resummation obtained in a Φ-derivable approach is gauge independent, free of thermal divergences and, in the weak-coupling limit, compatible with the leading order...

If synchronizing (rendez-vous) communications are used in Promela models, the priority choice feature (unless construct) and the weak fairness algorithm are not compatible with the partial order reduction algorithm used in Spin’s verifier. After identifying the wrong partial order reduction pattern that causes both incompatibilities, we give solutions to these two problems. To this end we propo...

Abstract G. Czédli proved that the blocks of any compatible tolerance T a lattice L can be ordered in such way they form / called factor modulo . Here we show Dedekind–MacNeille completion is isomorphic to concept context ( , R ), where stands for reflexive weak relation $$ \mathord {\le } \circ T$$ ≤ ...

This paper defines the agile enterprise as one which is able to both manage and apply knowledge effectively, and suggests that value from either capability is impeded if they are not in balance. It looks at the application of knowledge as requiring a change, and overviews a body of analytical work on change proficiency in business systems and processes. It looks at knowledge management as a str...
