Comparative genomic and phylogeographic analysis of Mycobacterium leprae

Stewart Cole, Jacques Rougemont, Philippe Busso, Pushpendra Singh, Alexandre Gattiker

Reductive evolution and massive pseudogene formation have shaped the 3.31-Mb genome of Mycobacterium leprae, an unculturable obligate pathogen that causes leprosy in humans. The complete genome sequence of M. leprae strain Br4923 from Brazil was obtained b ...

A VHDL-AMS Modeling Methodology for Top-Down/Bottom-Up Design of RF Systems

Alain Vachoux, Matteo Contaldo

This paper presents a modelling methodology for the top-down/bottom-up design of RF systems based on systematic use of VHDL-AMS models. The model interfaces are parameterizable and pin-accurate. The designer can choose to parameterize the models using perf ...

Modeling and validating the performance of atomic broadcast algorithms in high-latency networks

André Schiper, Nils Richard Ekwall

The performance of consensus and atomic broadcast algorithms using failure detectors is often affected by a trade-off between the number of communication steps and the number of messages needed to reach a decision. In this paper, we model the performance o ...

Hierarchical Routing over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

Dynamic networks are those where the topology changes over time and therefore efficient routes need to be maintained by frequent updates. Such updates could be costly in terms of consuming throughput available for data transmission, which is a precious res ...

Rapid and diverse route to natural product-like biaryl ether containing macrocycles

Jieping Zhu

A two-step sequence involving an Ugi four-component reaction and an intramol. nucleophilic arom. substitution (SNAr) has been developed for the rapid access to biaryl-ether contg. macrocycles. For example, reacting heptanal with butylamine, (3-hydroxypheny ...
