Acute insulin-induced hypoglycaemia in humans provokes autonomic neural activation and counterregulatory hormonal secretion mediated in part via hypothalamic stimulation. Many patients with Type 1 (insulin-dependent) diabetes have acquired deficiencies of counterregulatory hormonal release following hypoglycaemia. To study the integrity of the(More)
BACKGROUND Post-traumatic stress disorder (PTSD) is highly prevalent in children and adolescents who have experienced trauma and has high personal and health costs. Although a wide range of psychological therapies have been used in the treatment of PTSD there are no systematic reviews of these therapies in children and adolescents. OBJECTIVES To examine(More)
Psychological morbidity is high for women with breast cancer and is often undetected and untreated. Encouragingly, there are well-evaluated strategies to help improve psychological outcomes, but the challenge remains as to how to transfer these to routine care settings. The National Health and Medical Research Council (NHMRC) National Breast Cancer Centre(More)
A programmable FPGA-based digital logic circuit is enhanced with high-speed, positive emitter-coupled logic (PECL) to create a standalone tester for a self routing optical packet switching network. This tester serves as a test bed for evaluating high-speed electrical to optical conversion techniques and the difficulties associated with burst packet(More)
In this paper we present the design and performance characteristics for a custom test system developed to characterize a DWDM optically-routed packet switching network (called "Data Vortex"). The existing demonstration system supports aggregate data rates of 20 to 32 Gbps using 8 optical payload wavelengths each running at 2.5-4.0 Gbps. Several other(More)

This paper describes two research projects that develop new low-cost techniques for testing devices with multiple high-speed (2 to 5 Gbps) signals. Each project uses commercially available components to keep costs low, yet achieves performance characteristics comparable to (and in some ways exceeding) more expensive ATE. A common CMOS FPGA-based logic core(More)
DESA Th e Department of Economic and Social Aff airs of the United Nations Secretariat is a vital interface between global policies in the economic, social and environmental spheres and national action. Th e Department works in three main interlinked areas: (a) it compiles, generates and analyses a wide range of economic, social and environmental data and(More)
Although informing patients about medical risks is said to decrease the number of malpractice claims, most inpatients receive no information about hospital infection. Using a self-administered questionnaire, we surveyed 1270 healthcare workers randomly selected from 22 French hospitals to assess their opinion on information for patients about hospital(More)
BACKGROUND Children and adolescents who have experienced trauma are at high risk of developing post-traumatic stress disorder (PTSD) and other negative emotional, behavioural and mental health outcomes, all of which are associated with high personal and health costs. A wide range of psychological treatments are used to prevent negative outcomes associated(More)
