Anomalous Evolution of the Gottfried Sum

We discuss nonperturbative QCD evolution of nonsinglet nucleon structure functions, with particular application to the Gottfried sum. We show that the coupling of the quark partons to bound state mesons leads to nonperturbative contributions to the Altarelli– Parisi equations which, due to the axial anomaly, result in a strong scale dependence of nonsinglet structure functions for values of Q a...

Workflow Recovery * Johann Eder

WorkJlow management systems ( WFMSs) more and more become the basic technology for organizations to pei$orm their daily business processes (workjlows). A consistent and reliable execution of such processes is crucial for all organizations. We claim that this can only be achieved by integrating transactional features especially “workjlow transactions” into WFMSs. Based on this idea, we discuss i...
