—This paper presents a new traffic model for MPEG-encoded video sequences. The hybrid Gamma/Pareto distribution is used for all three types of frames in MPEG-encoded video sequences , and the present model takes scene changes into account. The autocorrelation structure is modeled using two second-order auto-regressive (AR) processes nested with each other.(More)
This paper presents an improved image steganography scheme based on absolute moment block truncation coding (AMBTC). The purpose of the proposed scheme is to achieve high payload, good visual quality and low computation complexity at the same time. In the scheme, a threshold is predefined to classify the blocks of the AMBTC-compressed codes as smooth or(More)
To identify susceptibility loci for schizophrenia, we performed a two-stage genome-wide association study (GWAS) of schizophrenia in the Han Chinese population (GWAS: 746 individuals with schizophrenia and 1,599 healthy controls; validation: 4,027 individuals with schizophrenia and 5,603 healthy controls). We identified two susceptibility loci for(More)
To search for potential protein markers of colorectal cancer (CRC), the changes in protein expression levels between microdissected tumor cells and normal mucosa epithelia were analyzed by an acetylation stable isotopic labeling method coupled with linear quadrupole ion trap fourier transform mass spectrometry (LTQ-FTMS). In total, 137 proteins were(More)
In this paper a new technique is introduced for automatically building recognisable moving 3D models of individual people. A set of multi-view colour images of a person are captured from the front, side and back using one or more cameras. Model-based reconstruction of shape from silhouettes is used to transform a standard 3D generic humanoid model to(More)
Five distinct organic anion transporter cDNAs, hOAT1-5, were isolated from human liver and kidney. hOAT1, 2, and 3 are homologous to their respective rat orthologues OAT1-3, whereas hOAT4 and 5 are novel clones that have not been identified in other species. hOAT1- and hOAT3-transfected cells showed uptake of p-aminohippurate and fluorescein. Cells(More)
This paper evaluates, via both analysis and simulation, the end-to-end (e2e) delay performance of aggregate scheduling with guaranteed-rate (GR) algorithms. Deterministic e2e delay bounds for a single aggregation are derived under the assumption that all incoming flows at an aggregator conform to the token bucket model. An aggregator can use any of three(More)
—In order to realize the Smart Grid vision, it is necessary to have guaranteed Quality of Service (QoS) for the communication and networking technology used in various stages of the Smart Grid, ranging from power generation, transmission, distribution, to the customer applications. The low cost wireless protocols such as Zigbee (using IEEE 802.15.4 defined(More)
