conclusions planning for the prevention of traffic accidents requires standardized data. as the foundation for crash prevention efforts, existing standard data infrastructures present policymakers and government officials with a great opportunity to strengthen and integrate existing accident information systems to better track road traffic injuries and fatalities. results an (mds) of a traffic ...

Electron-heating induced by a tunable, supplementary dc-current (Idc) helps to vary the observed magnetoresistance in the high mobility GaAs/AlGaAs 2D electron system. The magnetoresistance at B = 0.3 T is shown to progressively change from positive to negative with increasing Idc, yielding negative giant-magnetoresistance at the lowest temperature and highest Idc. A two-term Drude model succes...

With the development of agricultural production technology, characteristics that appear in the farmland information such as diversity, polytropy and dispersity. In order to solve the problems of obtaining quickly and long-distance transmission the farmland information, the paper proposes a farmland data acquisition system based on the GPRS technology. The system exerts GPRS network of the china...

OBJECTIVES Infectious diseases consultation (IDC) in adults with Staphylococcus aureus bacteraemia (SAB) has been shown to improve management and outcome. The aim of this study was to evaluate the impact of IDC on the management of SAB in children. STUDY DESIGN Observational cohort study of children with SAB. SETTING Cambridge University Hospitals National Health Service (NHS) Foundation Tr...

In the current dominant IaaS framework, the centralized VM image management mechanism leads to massive consumption of shared bandwidth resources of an IaaS data center (IDC) in face of a large amount of concurrent deployment tasks and has a limited image management ability in large scale IDCs formed by multiple physic server clusters, causing many problems for IDCs, such as, the performance deg...

BACKGROUND Accurate tracking of the administered dose of asthma rescue inhalers is critical for optimal disease management and is related to reductions in rates of unscheduled health care utilization in asthma patients. There are few published data on the real-world impact of rescue inhalers with integrated dose counters (IDCs) on health care resource utilization (HRU) for asthma patients. This...

­The volume of generated data increases by the rapid growth of Internet of Things (IoT), leading to the big data proliferation and more opportunities for data centers. Highly virtualized cloud-based datacenters are currently considered for big data analytics. However big data requires datacenters with promoted infrastructure capable of undertaking more responsibilities for handling and analyzin...

Internet access on cellular phones, after emerging as a new technology in the mid-1990s, is now a thriving activity despite the global economic recession. IDC reported smartphone sales of 1.18 billion units in 2008 (IDC, 2009), compared to the unconnected personal digital assistants approaching merely 1 million units per quarter in the second half of 2003. However, the concept of using handheld...
