On the Capacity Improvement of Multicast Traffic with Network Coding

open access: yes, 2008
In this paper, we study the contribution of network coding (NC) in improving the multicast capacity of random wireless ad hoc networks when nodes are endowed with multi-packet transmission (MPT) and multi-packet reception (MPR) capabilities. We show that

Temporal video transcoding from H.264/AVC-to-SVC for digital TV broadcasting [PDF]

open access: yes, 2015
Mobile digital TV environments demand flexible video compression like scalable video coding (SVC) because of varying bandwidths and devices. Since existing infrastructures highly rely on H.264/AVC video compression, network providers could adapt the ...

Fast Adaptive CU Partition Decision Algorithm for VVC Intra Coding

open access: yesIEEE Access, 2023
The latest video standard - Versatile Video Coding Standard (VVC/H.266) has been standardized and officially entered into force. Compared with the High Efficiency Video Coding (HEVC/H.265), owing to the introduction of the Quad-tree with Nested Multi ...

Spatio-temporal correlation based fast inter mode decision for HEVC

open access: yesTongxin xuebao, 2016
The new generation high efficiency video coding (HEVC) standard adopts coding tree unit (CTU) quadtree partition technology and ten inter prediction unit (PU) modes to improve compression efficiency significantly, but it brings in an enormous encoding ...

Learning-Based Rate Control for High Efficiency Video Coding

open access: yesSensors, 2023
High efficiency video coding (HEVC) has dramatically enhanced coding efficiency compared to the previous video coding standard, H.264/AVC. However, the existing rate control updates its parameters according to a fixed initialization, which can cause ...

Path Gain Algebraic Formulation for the Scalar Linear Network Coding Problem

open access: yes, 2010
In the algebraic view, the solution to a network coding problem is seen as a variety specified by a system of polynomial equations typically derived by using edge-to-edge gains as variables.

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

open access: yesFEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Universal and Robust Distributed Network Codes

open access: yes, 2010
Random linear network codes can be designed and implemented in a distributed manner, with low computational complexity. However, these codes are classically implemented over finite fields whose size depends on some global network parameters (size of the ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
