Reliable distributed protocols, such as consensus and atomic broadcast, are known to scale poorly with large number of processes. Recent research has shown that algorithms providing probabilistic guarantees are a promising alternative for such environments ...
We present a novel method to trace the propagation of intrusions or malicious code in networked systems. Our solution is aimed at large numbers of loosely managed workstations typical of a research environment as found in CERN. The system tags events which ...
It is important to establish reliable calculational tools to plan and analyse representative microdosimetry experiments in the context of microbeam radiation therapy development. In this paper, an attempt has been made to investigate the suitability of the ...

Two novel, potentially antimicrobial erythronolide aglycon analogs ((-)-9 and (-)-30, respectively), which incorporate a large number of contiguous stereogenic centers, have been prepared by multistep synthesis from simple chirons. The chemistry presented ...
Today the problem of semantic interoperability in information search on the Internet is solved mostly by means of centralization, both at a sys-tem and at a logical level. This approach has been successful to a certain extent. Peer-to-peer systems as a new ...
The spike timing in rhythmically active interneurons in the mammalian spinal locomotor network varies from cycle to cycle. We tested the contribution from passive membrane properties to this variable firing pattern, by measuring the reliability of spike ti ...
The Mulliken charges of the 12-metallacrown-3 complex (C6H6)Ru(C5H3NO2) were determined by a single point analysis at the HF level. For comparison, a Mulliken population analysis was carried out for the organic analogue 12-crown-3. The partial negativ ...
The rat neural cell line RN33B has a remarkable ability to undergo region-specific neuronal differentiation after transplantation into the CNS. To further study its neurogenic properties in vivo, we used a recombinant lentiviral vector to genetically label ...
In this report, we build up on our previous work on speaker clustering, where the number of speakers and segmentation boundaries are unknown a priori. We employ an ergodic HMM with minimum duration topology for this purpose. Starting from a large number of ...
We investigate numerically the spectrum of plasmon resonances for metallic nanowires with a nonregular cross section, in the 20-50 nm range. We first consider the resonance spectra corresponding to nanowires whose cross sections form different simplexes. T ...
