In this paper, we propose an adaptive synchronization control scheme to achieve both intra-stream and inter-stream synchronization for real-time streaming multimedia applications on the Internet. Based upon synchronization errors calculated in real-time, our scheme piecewisely adjusts the end-to-end delay to compensate for the delay variation. It does so by(More)
Artemisinins are the cornerstone of anti-malarial drugs. Emergence and spread of resistance to them raises risk of wiping out recent gains achieved in reducing worldwide malaria burden and threatens future malaria control and elimination on a global level. Genome-wide association studies (GWAS) have revealed parasite genetic loci associated with artemisinin(More)
During the last few years the Internet has grown tremendously and has penetrated all aspects of everyday life. Starting off as a purely academic research network, the Internet is now extensively used for education, for entertainment, and as a very promising and dynamic marketplace, and is envisioned as evolving into a vehicle of true collaboration and a(More)
Best-effort packet switch networks such as the Internet can not guarantee in-time delivery of packetizzed data units for networked multimedia applications. For a video conferencing system, the original temporal relationships among data units could be severely distorted without appropriate control. In this paper, we propose an adaptive delay and(More)
In the context of drug discovery and development, much effort has been exerted to determine which conformers of a given molecule are responsible for the observed biological activity. In this work we aimed to predict bioactive conformers using a variant of supervised learning, named multiple-instance learning. A single molecule, treated as a bag of(More)
The prevalence of the IEEE 802.11b technology leads to the emergence of Wi-Fi based AV conferencing applications. However, due to the "best-effort" transport service and other unpredictable factors such as user mobility, location and background traffic, the transport channel behavior often fluctuates drastically. It thus becomes rather difficult to(More)
The prevalence of the IEEE 802.11b technology has made Wi-Fi based Audio/Video (AV) conferencing applications a viable service. However, due to the " best-effort " transport service and other unpredictable factors such as user mobility, location and background traffic, the transport channel behavior often fluctuates drastically. It thus becomes rather(More)
As video becomes a fundamental part of advanced networking applications, being able to measure its quality has significant importance at all stages: starting from the development of new video codecs and ending to the monitoring the quality of the transmission system. Indeed, in order to appreciate and compare the performance of all involved components and(More)
Pancreatic cancer is highly invasive and is currently the fourth leading cause of cancer death worldwide. CXC chemokine receptor-4 (CXCR4) is a G protein-coupled receptor for CXC chemokine ligand 12/stromal cell-derived factor-1α (SDF-1α), a member of a large family of small, structurally related, heparin-binding chemokine proteins. SDF-1α/CXCR4 plays an(More)
Due to the lack of QoS support, ensuring an acceptable application level QoS for the real-time delivery of multi-object multimedia presentations on the current Internet is very challenging. Currently, the only feasible solution is to artificially " equalize " the variable network delays. In this paper, we first investigate the application-level objective(More)
