This paper presents the first complete design to apply compressive sampling theory to sensor data gathering for large-scale wireless sensor networks. The successful scheme developed in this research is expected to offer fresh frame of mind for research in both compressive sampling applications and large-scale wireless sensor networks. We consider the(More)
We present a novel 2-D wavelet transform scheme of adaptive directional lifting (ADL) in image coding. Instead of alternately applying horizontal and vertical lifting, as in present practice, ADL performs lifting-based prediction in local windows in the direction of high pixel correlation. Hence, it adapts far better to the image orientation features in(More)
In this paper, a basic framework for efficient scalable video coding, namely progressive fine granularity scalable (PFGS) video coding is proposed. Similar to the fine granularity scalable (FGS) video coding in MPEG-4, the PFGS framework has all the features of FGS, such as fine granularity bit-rate scalability, channel adaptation, and error recovery. On(More)
We proposed compressive data gathering (CDG) that leverages compressive sampling (CS) principle to efficiently reduce communication cost and prolong network lifetime for large scale monitoring sensor networks. The network capacity has been proven to increase proportionally to the sparsity of sensor readings. In this paper, we further address two key(More)
This paper proposes an efficient scalable coding scheme with fine-grain scalability, where the base layer is encoded with H.26L, and the enhancement layer is encoded with PFGS coding. Motion compensation with adaptive block size has greatly contributed to the coding efficiency improvement in H.26L. In order to improve efficiency of the enhancement layer(More)
Familial platelet disorder with predisposition to acute myelogenous leukemia (FPD/AML) is an autosomal dominant familial platelet disorder characterized by thrombocytopenia and a propensity to develop AML. Mutation analyses of RUNX1 in 3 families with FPD/AML showing linkage to chromosome 21q22.1 revealed 3 novel heterozygous point mutations (K83E,(More)
Mutant analyses in different eudicotyledonous flowering plants demonstrated that SEPALLATA-like MADS-box genes are required for the specification of sepals, petals, stamens and carpels, and for floral determinacy, thus defining class E floral organ identity genes. SEP-like genes encode MADS-domain transcription factors and constitute an angiosperm-specific(More)
BACKGROUND & AIMS Chronic inflammatory bowel diseases such as ulcerative colitis (UC) are associated with differential expression of genes involved in inflammation and tissue remodeling. MicroRNAs (miRNAs), which direct mRNA degradation and translational inhibition, influence a number of disease processes. We examined whether miRNAs are differentially(More)
This paper overviews the AVS video standard in terms of basic features, adopted major techniques and its pegormancr. The current version of AVS video standard mainly aims at the idcreasing demand on high definition and high quality video services. I t provides a good trade-off solution berween complexity and coding eficiency for digital broadcasi and(More)
