In the field of visual prosthesis research, it has generally been held that animal models are limited to testing the safety of implantable hardware due to the inability of the animal to provide a linguistic report of perceptions. In contrast, vision scientists make extensive use of trained animal models to investigate the links between visual stimuli,(More)
OBJECTIVES To determine which travellers with malaria are at greatest risk of dying, highlighting factors which can be used to target health messages to travellers. DESIGN Observational study based on 20 years of UK national data. SETTING National register of malaria cases. PARTICIPANTS 25,054 patients notified with Plasmodium falciparum malaria, of(More)
Children account for an appreciable proportion of total imported malaria cases, yet few studies have quantified these cases, identified trends, or suggested evidence-based prevention strategies for this group of travelers. We therefore sought to identify numbers of cases and deaths, Plasmodium species, place of malaria acquisition, preventive measures used,(More)
A utonomous navigation by a mobile robot through natural, unstructured terrain is one of the premier challenges in field robotics. Tremendous advances in autonomous navigation have been made recently in field robotics [1]–[3]. Machine learning has played an increasingly important role in these advances. The Defense Advanced Research Projects Agency (DARPA)(More)
Adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance; patients with sporadic adult-onset primary torsion dystonia are much more prevalent than familial. The temporal discrimination threshold is the shortest time interval at which two stimuli are detected to be asynchronous and has been shown to be abnormal(More)
The pathogenesis of adult-onset primary dystonia remains poorly understood. There is variable age-related and gender-related expression of the phenotype, the commonest of which is cervical dystonia. Endophenotypes may provide insight into underlying genetic and pathophysiological mechanisms of dystonia. The temporal discrimination threshold (TDT)-the(More)
