The performance of a space-based Automatic Identification System (AIS) receiver, can be estimated in terms of the probability of detection of an uncorrupted ship’s AIS message. Signal collisions arising from other ships outside its selforganizing cell often limit performance. A probabilistic approach based on Poisson statistics is adopted to predict this. The method takes account of the ability...

The population of ontologies with real instances still remains a major practical issue for the Semantic Web community. Significant progress towards a solution for this issue can be achieved through the migration of data stored in existing relational databases. In this paper we present a schema matching methodology and its implementation, necessary for further data migration. AIS SIGSEMIS BULLET...

In this study, the reliability of surface electromyographic data (root-mean-square) for volitional motor tasks drawn from a standardized protocol was assessed. For each motor task, 5 s epochs of data were analyzed with a new method to generate a measure called the voluntary response index (VRI). The VRI consists of two components, magnitude and similarity index (SI), that were separately analyz...

Introduction The adolescent idiopathic scoliosis (AIS) is the most common deformity arising during childhood. Although its aetiology remains unknown, we have demonstrated a differential dysfunction of melatonin signalling through Gi proteins in osteoblasts isolated from AIS patients, leading to their stratification into three functional subgroups. Herein we examine the molecular profiles of the...

BACKGROUND E2A-PBX1 fusion gene caused by t(1;19)(q23;p13), has been well characterized in acute lymphoid leukemia (ALL). There is no report on E2A-PBX1 fusion transcripts in non-small-cell lung cancer (NSCLC). METHODS We used polymerase chain reaction (PCR) to detect E2A-PBX1 fusion transcripts in human NSCLC tissue specimens and cell lines. We analyzed correlation of E2A-PBX1 fusion transcr...

STUDY DESIGN Anterior and posterior vertebral body heights were measured from sequential magnetic resonance imaging (MRI) scans of adolescent idiopathic scoliosis (AIS) patients and healthy controls. OBJECTIVE To measure changes in vertebral body height over time during scoliosis progression to assess how vertebral body height discrepancies change during growth. SUMMARY OF BACKGROUND DATA R...

Long-term follow-up of untreated patients with adolescent idiopathic scoliosis (AIS) indicates that, with the exception of some extremely severe cases, AIS does not have a significant impact on quality of life and does not result in dire consequences. In view of the relatively benign nature of AIS and the long-term complications of surgery, the indications for treatment should be reviewed. Furt...

For nearly half a century, biology has provided a rich source of inspiration for computing systems, the result of which is a large body of work that includes biologically-inspired algorithms such as artificial immune system (AIS). Despite the effort that has been invested in engineering these algorithms, relatively little research has focused on how best to extract the underlying biological pro...
