In this paper, we present a performance evaluation of a wide-area cluster system based on a rewallenabled Globus metacomputing toolkit. In order to establish communication links beyond the rewall, we have designed and implemented a resource manager called RMF (Resource Manager beyond the Firewall) and the Nexus Proxy, which relays TCP communication links beyond the rewall. In order to extend th...

To better understand intrinsic brain connections in major depression, we used a neuroimaging technique that measures resting state functional connectivity using functional MRI (fMRI). Three different brain networks--the cognitive control network, default mode network, and affective network--were investigated. Compared with controls, in depressed subjects each of these three networks had increas...

A 3200 g male infant was born at 40 weeks gestation to a 40-year-old gravida 4, para 3 mother. Pregnancy was uneventful and the infant was born via normal spontaneous vaginal delivery. The infant developed marked respiratory distress upon delivery and the heart rate remained below 100/min, for which the infant received positive pressure ventilation for 30 seconds with a bag and mask, then admit...

We propose an approach that can render environmental audio effects for a large number of concurrent voice users immersed in a large distributed virtual world. In an off-line step, our approach efficiently computes acoustic similarity measures based on average path length, reflection direction and diffusion throughout the environment. The similarity measures are used to adaptively decompose the ...

Concerns about the water–energy–food (WEF) nexus have motivated many discussions regarding new approaches for managing water, energy and food resources. Despite the progress in recent years, there remainmany challenges in scientific research on theWEF nexus, while implementation as a management tool is just beginning. The scientific challenges are primarily related to data, information and know...

BACKGROUND The paper reports on the importance of the interpersonal nexus within qualitative research processes, from a recent research project on patient experiences of shoulder surgery. Our aim is to reveal the importance of qualitative research processes and specifically the role of the interpersonal nexus in generating quality data. Literature related to the importance of human interactions...

StarSs is one of several programming models that try to relieve parallel programming. In StarSs, the programmer has to identify pieces of code that can be executed as tasks, as well as their inputs and outputs. Thereafter, the runtime system (RTS) determines the dependencies between tasks and schedules ready tasks onto worker cores. Previous work has shown, however, that the StarSs RTS may cons...

INTRODUCTION The National Emergency X-radiography Utilization Study (NEXUS) criteria are used extensively in emergency departments to rule out C-spine injuries (CSI) in the general population. Although the NEXUS validation set included 2,943 elderly patients, multiple case reports and the Canadian C-Spine Rules question the validity of applying NEXUS to geriatric populations. The objective of t...

The recent development of microarray technology provided unprecedented opportunities to understand the genetic basis of aging. So far, many microarray studies have addressed aging-related expression patterns in multiple organisms and under different conditions. The number of relevant studies continues to increase rapidly. However, efficient exploitation of these vast data is frustrated by the l...

Research on the nexus between energy consumption and economic growth is a fundamental topic for energy policy making and low-carbon economic development. Russia proves the third largest energy consumption country in the world in recent years, while little research has shed light upon its energy consumption issue till now, especially its energy–growth nexus. Therefore, this paper empirically inv...
