Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by motor and nonmotor signs and symptoms. To date, many studies of PD have focused on its cardinal motor symptoms. To study the nonmotor signs of early PD, we investigated the reactions solicited by heat pain stimuli in early untreated PD patients without pain using fMRI. The(More)
Services being developed by the EU Agentcities project require, and would benefit from having security. This paper focuses on analysing and specifying agent security services for an Agentcities e-Banking service. In this version of the service we have defined a set of requirements for core, general and Multi-Multi Agent Systems (MMAS) scenarios to support(More)
Lymphocyte to monocyte ratio (LMR) has shown prognostic value in different types of cancer. This study assessed the prognostic performance of LMR in early-stage non-small cell lung cancer (NSCLC) patients and investigated the influence of LMR on the treatment response in patients receiving first-line platinum-based chemotherapy. Four hundred eighty-eight(More)
Meta-reasoning models are investigated in order to deliberate about the security requirements and interoperability within open service environments. This is particularly useful within such infrastructures as it enables us to: detect, analyse and resolve multiple policy conflicts; decide if a change in the environment necessitates a security reconfiguration(More)
Agentcities is a worldwide initiative designed to help realize the commercial and research potential of agent-based applications by constructing an open distributed network of platforms hosting diverse agents and services. The ultimate aim of the Agentcities initiative is to enable the dynamic, intelligent and autonomous composition of services to achieve(More)
OBJECTIVES The objectives of this study are to compare the effects of two nursing intervention models on the ability of preschool children with malignant tumors to socialize and to determine if these interventions improved their social adaption capability (SAC) and quality of life. METHODS Inpatient preschool children with malignant tumors admitted to the(More)
Dynamic service synthesis is one of the key aims of the EU Agentcities project [1]. This seeks to generate new services through reusing and combining existing services. Agent-based services are commonly represented and accessed using specific ontologies and they are advertised using terms from these same ontologies. Some event-based services such as a(More)
Communication between multi-agent platforms has shown potential problems in aspects of security, for example confidentiality, authentication and integrity. To address some these issues, this document focuses on analysing and specifying inter-platform agent security in general. In this initial document, we investigate various core requirements and the S/MIME(More)
