EMBO reports VOL 4 | NO 11 | 2003 ©2003 EUROPEAN MOLECULAR BIOLOGY ORGANIZATION 1008 Over the past few years, nanotechnology has emerged as a new and exciting research field that deals with the design, synthesis and fabrication of structures at the molecular scale. Smallness is not in itself the prime goal; it is rather the expectation that, by manipulating matter at the molecular level, new in...

Numerous scientific and analysis problems involve integrating heterogeneous information that is multidimensional, multivariate, and time-dependent. To visualize this data in a 3D environment, we designed a visualization technique called multiple scale small multiples (MSSM), in which each view behaves like an environment in itself. Aggregated multiple views can also form single view visualizati...

We consider astrophysically relevant nonlinear MHD dynamo at large Reynolds numbers (Re). We argue that it is universal in a sense that magnetic energy grows at a rate which is a constant fraction C(E) of the total turbulent dissipation rate. On the basis of locality bounds we claim that this "efficiency of the small-scale dynamo", C(E), is a true constant for large Re and is determined only by...

The proposed universality of small scale turbulence is investigated for a set of measurements in a cryogenic free jet with a variation of the Reynolds number (Re) from 8500 to 10(6) (max(R(lambda) approximately 1200). The traditional analysis of the statistics of velocity increments by means of structure functions or probability density functions is replaced by a new method which is based on th...

While network simulators are commonly used to test MANET routing protocols, no similar tool exist to perform evaluations of implementations with real hardware. In this paper, a solution to emulate MANET topologies and to assist implementations debugging is described. It uses well known UNIX networking features to enhance and ease interoperability tests, as well as MANET demonstrations. The syst...
