Coherent behavior of spinor Bose-Einstein condensates is studied in the presence of a significant uncondensed (normal) component. Normal-superfluid exchange scattering leads to near-perfect local alignment between the spin fields of the two components. We observe that, through this spin locking, spin-domain formation in the condensate is vastly accelerated as the spin populations in the condens...

Only little is publicly known about traffic in noneducational data centers. Recent studies made some knowledge available, which gives us the opportunity to create more realistic traffic models for data center research. We used this knowledge to create the first publicly available traffic generator that produces realistic traffic between hosts in data centers of arbitrary size. We characterize t...

The University of Southern California (USC) Center for Enrollment Research, Policy, and Practice, dedicated to research and action that advances the societal benefit of enrollment policies and practices in higher education, sought to shed light on professional preparation, career path and development issues related to chief admission officers and enrollment managers.1 Literature on these elemen...

In this paper we discuss the following issue: How do we decide whether a certain property of language is a competence property or a performance property? Our claim is that the answer to this question is not given a-priori. The answer depends on the formal devices (formal grammars and machines) available to us for describing language. We discuss this issue in the context of the complexity of pro...

The dynamics of matter-wave solitons in Bose-Einstein condensates (BEC) is considerably affected by the presence of a thermal cloud and the dynamical depletion of the condensate. Our numerical results, based on the time-dependent Hartree-Fock-Bogoliubov theory, demonstrate the collapse of the attractively interacting BEC via collisional emission of atom pairs into the thermal cloud, which split...

In this paper, we present a measurement based characterization of the Ultra Wideband (UWB) channel in a data center environment. We find that although a modified Saleh-Valenzuela model characterizes the UWB channel, some of the model parameters such as delay spread and log normal shadowing are unique to the data center environment.

The approach of Business Intelligence (BI) as a support function for management decisions is established in practice and theory. BI can not just be considered as a simple sequence of isolated single projects. Its coordination requires permanent efforts to keep the BI function and the business organization in alignment. In the context of the present empirical study, BI organizations have been an...
