—P2P video streaming is receiving enormous attention , and when video is involved, the efficient use of the network becomes a very important issue, specially if live applications are addressed. In this work we study properties of Push/Pull protocols for the exchange of video chunks in non-structured systems. Push/Pull protocols are a broad class of chunk(More)
BACKGROUND Vasoconstrictive, proliferative and oxidative effects of angiotensin II (Ang II) are mediated by Ang II type 1 (AT1) receptors. The effects of Ang II via the Ang II type 2 (AT2) receptor subtype (AT2R) are less well defined. Growing evidence shows the existence of cross-talk between the Ang II receptor subtypes, which is revealed by AT1R(More)
Hepatocellular carcinoma (HCC) is a heterogeneous disease triggered by various risk factors and frequently characterized by chromosome instability. This instability is considered to be caused primarily by Hepatitis B virus (HBV), although aflatoxin B1 (AFB1), a potent fungal mutagen is also suspected to influence chromosomal repair. We studied 90 HCCs from(More)
—The peer-to-peer communication paradigm is changing the way the Internet works, and the perspective network and service providers are looking at the telecommunication business. P2P applications and networks are taking foot by the day, and new systems are proposed continuously with ever novel features and better performances. In spite of attention and(More)
The therapeutic landscape of non-small-cell lung cancer (NSCLC) has dramatically changed in the last few years with the introduction of molecularly targeted agents, leading to unprecedented results in lung tumors with a paradigmatic shift from a "one size fits all" approach to an histologic and molecular-based approach. The discovery of epidermal growth(More)
Practical implementation of new P2P streaming systems requires a lot of coding and is often tedious and costly, slowing down the technology transfer from the research community to real users. GRAPES aims at solving this problem by providing a set of open-source components conceived as basic building blocks for building new P2P streaming applications which(More)
Brain metastases (BMs) represent a major issue in clinical practice and are associated with a significant worsening of patient's quality of life and, often, a dismal prognosis. Breast cancer (BC) is the second most common solid malignancy that metastasizes to the central nervous system. Incidence of BM varies according to the tumor subtype, with higher(More)
Multicast operations across wireless networks have received much attention, involving network architectures that range from ad-hoc networks to structured multi-hop meshes layouts. The use for this purpose of the standard Protocol Independent Multicast (PIM) protocol suite has been dismissed as non practical, or non feasible, noting that its straightforward(More)
