A new error resilient method based on data partitioning and unequal error protection for H.264 video transmission over wireless network is proposed in this paper. By introducing the Impact factor of Inter MB and /spl rho/-curve, the method further divides the C type partition into several subtypes according to their effects to error propagation, then(More)
Scalable video representation of the state-of-art scalable extension of the H.264/MPEG-4 AVC (SVC) and its combined 3d scalability feature offer an excellent solution to flexible video multicast over IP network. In order to relieve the impact of the severe bandwidth fluctuations and packet loss to the reconstructed quality in heterogeneous networks like the(More)
Ebola virus (EBOV) causes a highly lethal hemorrhagic fever syndrome in humans and has been associated with mortality rates of up to 91% in Zaire, the most lethal strain. Though the viral envelope glycoprotein (GP) mediates widespread inflammation and cellular damage, these changes have mainly focused on alterations at the protein level, the role of(More)
In this study, curcumin (Cur) loaded mixed micelles (Cur-PF), composed of Pluronic P123 (P123) and Pluronic F68 (F68), was prepared using the thin-film hydration method and evaluated in vitro. The preparation process was optimized with a central composite design (CCD). The average size of the mixed micelles was 68.2 nm, and the encapsulating efficiency for(More)
In this paper, we propose an error concealment algorithm based on non-uniform Lagrange interpolation for H.264 standard. To increase the accuracy of error concealment algorithm we utilize the 4 4 pixel block interpolation mode supported by H.264 standard, each of 4 4 pixel block has several directional interpolation modes, total MV (Motion Vector)(More)
Recently, scalable video coding technique has attracted a lot of attention for its desired scalable functionality and coding efficiency. H.264/SVC encodes a video in a hierarchical way by which the coded bit stream can satisfy terminals with different capability of display and different condition of network at the same time. However, the huge computational(More)
Network coding is an emerging and powerful solution that can significantly improve the throughput and power efficiency of wireless networks by allowing mixing of various traffic flows into a single packet. However, when network coding is applied, a packet will have to wait to be network-coded with others, which may result on large delay and packet-loss(More)
UNLABELLED As a recycling center, lysosomes are filled with numerous acid hydrolase enzymes that break down waste materials and invading pathogens. Recently, lysosomal cell death has been defined as "lysosomal membrane permeabilization and the consequent leakage of lysosome contents into cytosol." Here, we show that the neuraminidase (NA) of H5N1 influenza(More)
