A charged superconductiong cosmic string produces an extremely large electric field in its vicinity. This leads to vacuum instability and to the formation of a charged vacuum condensate which screens the electric charge of the string. We analyze the structure of this condensate using the ThomasFermi method. PACS number(s): 98.80.Cq Electronic Address: [email protected]. tufts.edu Electronic ...

he change in the postal sector over the past 20 years and in particular the are transforming the postal services industries such as institutional, market and ents. Taking the argument from here this paper defines the four major response erators all across the world to analyse how different firms and countries are enges of increased competition and changing consumer behaviour, also in ing libera...

Bearing the responsibility of the rising strategy of central region of China, Changsha-Zhuzhou-Xiangtan Urban Agglomeration is an important growth pole of the development of the Yangtze river economic belt. Reasonable position of urban function in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, is an inevitable requirement for the cooperative development of regional economy in Changsha, Zhuzhou ...

We derive a lower bound for the sta ng levels required to meet a projected load in a retail service facility. We model the queueing system as a Markovian process with nonhomogeneous Poisson arrivals. Motivated by an application from the postal services, we assume that the arrival rate is piecewise constant over the time horizon and retain such transient e ects as build-up in the system. The opt...
