background institut pasteur international network (ipin), which includes 32 research institutes around the world, is a network of research and expertise to fight against infectious diseases. a scientometric approach was applied to describe research and collaboration activities of ipin.   methods publications were identified using a manual search of ipin member addresses in science citation inde...

As the web evolves, it is becoming easier to form communities based on shared interests, and to create, publish, and query data on a wide variety of topics. In order to fully deliver on the promise of free data exchange, any community-supporting infrastructure needs to enforce the key requirement to preserve privacy of the association of content providers with potential sensitive published info...

Reflective cracking is a common distress of semi-rigid base asphalt pavements and overlay pavement projects. An rubber stress-absorbing membrane interlayer (AR-SAMI) prepared by waste tires an effective engineering solution for treating reflective cracking. This method can also reduce black pollution. However, there no unified test index crack resistance evaluation. In this work, AR-SAMIs with ...

Let Z2 = {0, 1} and G = (V ,E) be a graph. A labeling f : V → Z2 induces an edge labeling f* : E →Z2 defined by f*(uv) = f(u).f (v). For i ε Z2 let vf (i) = v(i) = card{v ε V : f(v) = i} and ef (i) = e(i) = {e ε E : f*(e) = i}. A labeling f is said to be Vertex-friendly if | v(0) − v(1) |≤ 1. The vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. In this paper ...

The research community has turned to create Semantic Overlay Networks for information retrieval in large scale peer-to-peer networks. Much research work in semantic overlay protocols and searching algorithms is done and their results indicate that semantic overlay is powerful for content searching in peer-to-peer network. However, very limited work has been done in analyzing and evaluating char...

Overlay routing is an application-level routing mechanism on overlay networks. Previous researches have revealed that the overlay routing can improve user-perceived performance. However, it may also generate traffic unintended by ISPs, incurring additional monetary cost. In addition, since ISPs and end users have their own objectives respectively regarding traffic routing, overlay routing must ...

Formation of suitable overlay-network topologies that are able to reflect the structure of the underlying network-infrastructure, has rarely been addressed by peer-to-peer applications so far. Often, peer-to-peer protocols restrain to purely random formation of their overlay-network. This leads to a far from optimal performance of such peer-to-peer networks and ruthlessly wastes network resourc...

When transport in networks follows the shortest paths, the union of all shortest path trees G union or logical sum SPT can be regarded as the "transport overlay network." Overlay networks such as peer-to-peer networks or virtual private networks can be considered as a subgraph of G union or logical sum SPT. The traffic through the network is examined by the betweenness Bl of links in the overla...

Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...
