— We propose a synchronization control scheme which achieves both speech/video Intra-Stream synchroniza-tions and Inter-Stream synchronization for videoconferenc-ing services over IP networks. The driving principle of our scheme is to guarantee the Intra-Sync speech timing relationships (hence the speech quality) and to adjust the video Intra-Sync and the(More)
BACKGROUND The clinical efficacy of the current methods used for cryopreservation of metaphase II human oocytes is low. Meiotic spindle disorders are thought to be largely responsible for this situation. METHODS Supernumerary fresh metaphase II human oocytes were cryopreserved in 1,2-propanediol with 0.1 M sucrose using a slow freezing/rapid thawing(More)
In [1] we introduced a new real-time variable frame rate control scheme. It is based on the video jerkiness and it can be applied to both coding and transcoding. This scheme constantly traces the motion of the incoming video and automatically tunes the outgoing frame rate according to the level of jerkiness acceptable by the user. This scheme has been(More)
The X-linked dominant form of Charcot-Marie-Tooth syndrome (CMTX) is a clinically and genetically heterogeneous hereditary disorder of the peripheral nerves caused by mutations in the GJB1 gene that encodes a gap junction protein named connexin 32 (Cx32). Clinically, CMTX is characterized by peripheral motor and sensory deficit with muscle atrophy. A couple(More)
This paper describes the requirements and challenges on WAN due to NFV in case of datacenter interconnections crossing heterogeneous domains for technology, control and vendors. It is presented a new architecture with novel functional building blocks between transport and service layers named E2E harmonization. Such architecture allows efficient(More)
Admission Control and routing are key aspects in next generation networks supporting advanced Quality of Service and Traffic Engineering functionalities. However, traditional Traffic Engineering solutions usually rely exclusively on routing algorithms to achieve optimization in network resource usage, while Admission Control is simply limited to a local(More)
