BACKGROUND The current study explored the association between green space and depression in a deprived, multiethnic sample of pregnant women, and examined moderating and mediating variables. METHOD 7547 women recruited to the 'Born in Bradford' cohort completed a questionnaire during pregnancy. A binary measure of depressive symptoms was calculated using a validated survey. Two green space me...

Scientific discoveries are increasingly dependent upon the analysis of large volumes of data from observations and simulations of complex phenomena. Scientists compose the complex analyses as workflows and execute them on largescale HPC systems. The workflow structures are in contrast with monolithic single simulations that have often been the primary use case on HPC systems. Simultaneously, ne...

HEALERS is a practical, high-performance toolkit that can enhance the robustness and security of existing applications. For any shared library, it can find all functions defined in that library and automatically derives properties for those functions. Through automated faultinjection experiments, it can detect arguments that cause the library to crash and derive safe argument types for each fun...

The routing and signaling protocols for supporting multipoint-to-multipoint connections in ATM networks have been presented earlier. VP-Merge and VC-Merge techniques have been proposed as the likely candidates for resolving the sender identification problem associated with these connections. The additional buffer requirements in the VC-Merge mechanism and the excessive use of VPI/VCI space in t...

As there is a tremendous increase in the demand for the data dissemination in wireless networks, it is necessary to investigate an effective mechanism in order to improve the cooperative data dissemination in telematic applications. In this paper we have considered cooperative data dissemination with respect to Roadside WLANs as an infrastructure. With respect to cooperative data dissemination ...

High latency and loss rates in the Internet make it difficult to stream audio and video without introducing a large playback delay. To address these problems, we propose a prefix caching technique whereby a proxy stores the initial frames of popular clips. Upon receiving a request for the stream, the proxy initiates transmission to the client and simultaneously requests the remaining frames fro...
