We offer a powerful peer-to-peer scheme for the efficient organization of very large scale dynamically distributed systems such as ad hoc mobile networks and computer grids. The architecture is realized as a logical overlay of a two-dimensional concentric multi-ring topology (illustrated above) with the best robust resource distribution and discovery algorithm available. The latter allows no more than DHiPeer steps to retrieve any resource in the network with DHiPeer = logd (N(d-1) +d) -1, where DHiPeer is the minimum diameter (distance between nodes), d is a given fixed maximum degree (connectivity) of each node and N is the number of nodes. Each node holds a routing table of constant size 2d + 3 and can join or leave the network for a controlled constant cost ~O(d) which is independent of the number of nodes in the network. This solution does not exhibit the typical disadvantages of common computation and communication architectures such as high bandwidth consumption, centralized directory structure and non-consistent distribution of resources. It is fast, reliable and cost efficient and can be implemented in systems of unlimited size.<br><br> <p><strong>Benefits</strong><br> <ul type="disc">

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
