One of the crucial aspects of density perturbations that are produced by the standard inflation scenario is that they are Gaussian where seeds produced by topological defects tend to be non-Gaussian. The three point correlation function of the temperature anisotropy of the cosmic microwave background radiation (CBR) provides a sensitive test of this aspect(More)
BACKGROUND Since human infection with the novel H7N9 avian influenza virus was identified in China in March 2013, the relatively high mortality rate and possibility of human-to-human transmission have highlighted the urgent need for sensitive and specific assays for diagnosis of H7N9 infection. METHODOLOGY/PRINCIPAL FINDINGS We developed a rapid(More)
Information about the physical processes that generate the primordial fluctuations in the early universe can be gained by testing the Gaussian nature of the fluctuations through cosmic microwave background radiation (CBR) temperature anisotropy experiments. One of the crucial aspects of density perturbations that are produced by the standard inflation(More)
Malaria presents a considerable threat to public health. Histidine-rich protein 2 (HRP 2) is the major protein released into human blood upon infection by Plasmodium falciparum. In this study, we aimed to evaluate the immunogenicity of HRP 2 exon II and the efficacy of novel monoclonal antibodies (mAbs) against HRP 2 for Point-of-Care Test (POCT). The(More)
The low sensitivity and specificity of Plasmodium falciparum diagnostic tests pose a serious health threat to people living in endemic areas. The objective of the study was to develop a rapid assay for the detection of histidine-rich protein 2 (HRP2) of P. falciparum in whole blood by immunofluorescence chromatographic technology. A total of 1163 positive(More)
Xiaochun is a Ph.D. candidate of the Department of Building and Real Estate, Hong Kong Polytechnic University. His research interests focus on applying artificial intelligence techniques, e.g. case-based reasoning (CBR) and natural language processing, to construction industry. He is currently involved in developing a comprehensive solution integrating CBR(More)
I investigate geometric and mechanical sensing strategies for objects of known shapes. Examples include industrial parts and everyday desktop items. Based on nonlinear control theory, I show that local observability from contact holds in typical manipulation tasks, and I present an approach for estimating the pose and motion of a manipulated object from a(More)
