A scalable feedback mechanism to solicit feedback from a potentially very large group of networked nodes is an important building block for many network protocols. Multicast transport protocols use it for negative acknowledgements and for delay and packet ...
Finding relevant segments in meeting recordings is important for summarization, browsing, and retrieval purposes. In this paper, we define relevance as the interest-level that meeting participants manifest as a group during the course of their interaction ...
When treated with BuLi and KOCMe3 for 2 h at 0 Deg in hexane, the unsatd. monoterpenic alc. isopulegol is simultaneously deprotonated at the hydroxy function and the allylic Me group. The metaloxy allylmetal species thus generated can be silylated, alkylat ...
Professor James E. Bailey was not only a world-renowned leader and pioneer in biochem. engineering but also a mentor to the many graduate students and postdoctoral researchers in his group. To provide non-"Bailey-ites" with an impression of Jay as a mentor ...
With the aim to develop a general approach to a total synthesis of amino-acylated t-RNAs and analogs, we describe the synthesis of stabilized, amino-acylated RNA fragments, which, upon ligation, could lead to amino-acylated t-RNA structures. Novel RNA phos ...
Two sets of RNA phosphoramidites, carrying the (fluoride-labile) 2'-O-[(triisopropylsilyl)oxy]methyl (tom) group and the (photolabile) [(R)-1-(2-nitrophenyl)ethoxy]methyl ((R)-npeom) group, were prepd. The two protecting groups were completely orthogonal t ...
This thesis work aimed to show the potentialities of the organometallic approach and, in particular, the organoalkali one, in Organic Synthesis (whose possibilities cannot be underestimated). A wide opening on the big landscape of possibilities has been re ...
We determine all maximal subgroups of the direct product G^n of n copies of a group G. If G is finite, we show that the number of maximal subgroups of G^n is a quadratic function of n if G is perfect, but grows exponentially otherwise. We deduce a theorem ...
This paper provides an overview of the SWARM-BOTS project, a robotic project sponsored by the Future and Emerging Technologies program of the European Community (IST-2000-31010). The paper illustrates the robot hardware, and the results of experimental wor ...
Hassibi, Hochwald, Shokrollahi and Sweldens (see tech. rep., Bell Laboratories, Lucent Technologies, 2000) classified all finite groups of unitary matrices with nonzero diversity product. It is well-known, however, that differential space- time codes with ...
