The Internet has enabled the creation of a growing number of large-scale knowledge bases in a variety of domains containing complementary information. Tools for automatically aligning these knowledge bases would make it possible to unify many sources of structured knowledge and answer complex queries. However, the efficient alignment of large-scale(More)
The aim of this study was to evaluate the type and frequency of falls presenting to an inner city casualty department, and to identify modifiable risk factors in these patients. A prospective descriptive study evaluated those over 65 years presenting to an inner city casualty department with falls. Over a 4-week recruitment period, all consenting subjects(More)
OBJECTIVE To determine the prevalence of carotid sinus hypersensitivity and orthostatic hypotension in older patients with non-accidental falls attending an accident and emergency department. DESIGN A prospective case-control non-randomized study. Data were collected from semi-structured interviews, physical examination and neurocardiovascular(More)
INTRODUCTION The primary goal of stereotactic systems in deep brain stimulation (DBS) surgery is accurate delivery of a DBS lead to a target identified on imaging. Thus, it is critical to understand the accuracy of the stereotactic systems and the factors which may be associated with a decrease in accuracy. METHODS Ninety patients underwent microelectrode(More)
AIMS To ascertain the proportion of adults with a pacemaker in situ attending the Accident and Emergency Department because of syncope or unexplained falls and the cause of index symptoms in these patients, including the prevalence of hypotensive syndromes. METHODS AND RESULTS Patients presenting to the Accident and Emergency Department with unexplained(More)

Detailed observations of larval Drosophila chemotaxis have characterised the relationship between the odour gradient and the runs, head casts and turns made by the animal. We use a computational model to test whether hypothesised sensorimotor control mechanisms are sufficient to account for larval behaviour. The model combines three mechanisms based on(More)
