In this paper we propose a BWT-based LZW algorithm for reducing the compressed size and the compression time. BWT and MTF can expose potential redundancies in a given input and then significantly improve the compression ratio of LZW. In order to avoid the poor matching speed of LZW on long runs of the same character, we propose a variant of RLE named RLE-N.(More)
Estimating the cardinality of data streams over a sliding window is an important problem in many applications, such as network traffic monitoring, web access log analysis and database. The problem becomes more difficult in large-scale data streams when time and space complexity is taken into account. In this paper, we present a novel randomized data(More)
BACKGROUND Neonatal mortality reduction in China over past two decades was reported from nationwide sampling surveys, however, how high risk pregnancy affected neonatal outcome is unknown. The objective of this study was to explore relations of pregnancy complications and neonatal outcomes from a regional birth population. METHODS In a prospective,(More)
OBJECTIVE To improve the immunoblotting of immunoprecipitated proteins and decrease the interference of immunoprecipitation antibody in the interaction of endogenous proteins. METHODS Transient transfect cells with fusion protein expression vector containing the targeted S5b gene and the FLAG tag, the transfected cells or untransfected cells were(More)
We present an algorithm called Projected Displaced-Mesh (PDM) based on projected-grid for terrains. This algorithm is different from the previous algorithms. Our algorithm uses Displaced-Mesh. It creates terrain mesh by projecting, and then displaces the vertices from height field. Because of the use of projection, the algorithm has automatic view dependent(More)
This paper introduces View-dependent Projective Atlases (VPAs), a new algorithm for rendering height field and dynamic vector primitives in a uniform way. VPAs create projective region based on the intersections of view frustum with height field bounding boxes. This projective region is split with a dynamical and view-dependent algorithm to calculate the(More)
