Measuring the hyperfine structure (HFS) of long-lived P2 states of divalent atoms may offer the opportunity of extracting relatively unexplored nuclear magnetic octupole and electric hexadecapole moments. Here, using relativistic many-body methods of atomic structure and the nuclear shell model, we evaluate the effect of these higher nuclear moments on the hyperfine structure. We find that the ...

Data-center administrators perform traffic-management tasks (e.g., performance monitoring, server load balancing, and traffic engineering) to optimize network performance for diverse applications. Increasingly, traffic-management functionality is moving from the switches to the end hosts, which have more computational resources and better visibility into application behavior. However, traffic m...

The paper describes the traffic handling mechanisms implemented in the AQUILA pilot QoS IP network [AQUILA Project Consortium (2001)]. The AQUILA architecture enhances the DiffServ concept [A Conceptual Model for DiffServ Routers (2000), An Architecture for Differentiated Services (1998), An Expedited Forwarding PHB (2001)] by adding new functionality for admission control and resource manageme...

Organizations are at the heart of multi-agent systems. To deal with the ongoing dynamics and changes in the system, organizations have to adapt. Typically, agents are responsible to deal with the complexity of organization dynamics. In this paper, we present an approach for context-driven dynamic organizations in which the agent environment takes the burden of managing organization dynamics. Dr...

A universal description of the hyperfine splittings (HFS) in bottomonium and the Bq (q 1⁄4 n, s, c) mesons is obtained with a universal strong coupling constant sð Þ 1⁄4 0:310 in a spin-spin potential. Other characteristics are calculated within the field correlator method, taking the freezing value of the strong coupling independent of nf. The HFS MðB Þ MðBÞ 1⁄4 45:5ð1Þ MeV, MðB sÞ MðBsÞ 1⁄4 4...

Human Flesh Search((HFS) is a search phenomenon emerging on the Internetin recent years, which integrates machine search and manual search, and is usually used to find or identify immoral events or characters. But problematically in the process of HFS, the personal information of search objects is posted on the Internet, which seriously violates the privacy protection of the search objects and ...

Network operators want additional functionality from the networks they manage. The current approach to add functionality is to deploy middleboxes. Unfortunately middleboxes raise concerns regarding robustness, correctness, and efficiency due to their need to be deployed at chokepoints. This paper provides some initial thoughts for solving the middlebox problem in an architectural way. We believ...

Due to the increasing requirements on quality of service (QoS) for multimedia applications, wide area networks must be able to provide end-to-end performance guarantees. The ATM protocol, which offers an extensive traffic management functionality, achieves QoS in networks by providing various categories with different quality of service features. However, it is expensive and incompatible to the...

The fast growth of user-generated content puts a significant burden on the current network infrastructure. By implementing caching functionality on network infrastructure, we can effectively eliminate redundant traffic, reduce delay and achieve other goals. In my thesis, we utilize optimization model and design of heuristic to study and develop novel caching strategies with multiple objectives ...

This paper presents a model for the expected throughput in a Bluetooth network in presence of a number of other Bluetooth networks that cause radio interference. The analysis considers unidirectional traffic and makes worst-case assumptions on the effect of radio interference. In order to verify the model, simulation results are presented. The results from this work may be very useful when desi...
