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...

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...

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...

BACKGROUND AND PURPOSE Polyglycolic/polylactic acid (PGLA) addition to bare platinum coils is intended to reduce the reopening rate of coiled intracranial aneurysms. Nexus coils are standard complex platinum coils with interwoven PGLA microfilament threads. We present the clinical results of 101 intracranial aneurysms treated with Nexus coils. MATERIALS AND METHODS Results of coiling of 101 a...

Nexus Network Learner is an intelligent agent based simulation used to study Irregular Warfare (IW) in several major studies at the Department of Defense (DoD). Heterogeneous autonomous agents, each with their own separated inductive learning mechanism, have initial attributes and behaviors in proportion to demographic groups in the simulated population, and learn new behaviors as they serve cu...

Several works have recently shown that Android’s security architecture cannot prevent many undesired behaviors that compromise the integrity of applications and the privacy of their data. This paper makes two main contributions to the body of research on Android security: first, it develops a formal framework for analyzing Android-style security mechanisms; and, second, it describes the design ...

The paper examines the temporal relationship between revenues and expenditures for the four southern states during 1980 to 2005. Using an error-correction model and Granger causality test, it finds that the taxspend hypothesis is supported by the analsysis. The spend-tax hypothesis is valid for Karnataka; fiscal synchronization hypothesis is supported for Andhra Pradesh and Kerala, while the da...

The “water-energy-food nexus” has become an increasingly popular way to frame the challenges associated with reconciling human development objectives with responsible management of natural resources and ecosystems. Yet the nexus is complex, requiring effective engagement between expert and Non-expert stakeholders in order to understand biophysical inter-linkages between resources and resource f...

The present paper is an essay that aims at contributing to the debate on the social thinking architecture, a theoretical hierarchical model originally proposed by Rouquette that establishes relations between various symbolic formations. Other than addressing the main characteristics of social thinking and the architecture, a broad review of the role of its classical constructs is presented, i.e...
