Cayley Graphs and growth of groups

Nathalie Pellet

One of the most fundamental objects in algebra is the group. There exist plenty of different groups. In the following article we consider some free abelian gorups, cyclic groups, free groups and fundamental groups as well as the products of groups and draw ...

Advances in the Design and Implementation of Group Communication Middleware

André Schiper, Sergio Mena, Olivier Rütti, Rachele Fuzzati, Daniel Bünzli

Group communication is a programming abstraction that allows a distributed group of processes to provide a reliable service in spite of the possibility of failures within the group. The goal of the project was to improve the state of the art of group commu ...

Drug loading of porous coating

Heinrich Hofmann, Laurent-Dominique Piveteau

Porous coating for the controlled release of drugs, said coating comprising a porous structure with pores adapted to act as reservoirs or as passages for a drug, in such a way that said drug can move from the external environment to/from or through said po ...

The SWARM-BOTS project

Dario Floreano, Francesco Mondada, Roderich Gross, Jean-Louis Deneubourg, Luca Maria Gambardella

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 ...

Jay Bailey as mentor-the students' perspective

Vassily Hatzimanikatis

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 ...

Torsion endo-trivial modules

Jacques Thévenaz

We prove that the group T(G) of endo-trivial modules for a non-cyclic finite p-group G is detected on restriction to the family of subgroups which are either elementary abelian of rank 2 or (almost) extraspecial. This result is closely related to the probl ...

Isopulegol as a model compound. Metalation and substitution of an allylic position in the presence of an unprotected hydroxy function

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 ...

Maximal subgroups of direct products

Jacques Thévenaz

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 ...

Substituent Effects on the Regioselectivity of the Baeyer-Villiger Oxidation of 7-Oxabicyclo[2.2.1]Heptan-2-Ones

Pierre Vogel

New 3-oxy substituted and 3,6-dioxydisubstituted 7-oxabicyclo[2.2.1]heptan-2-ones have been prepared. The regioselectivity of their Baeyer-Villiger oxidation has been determined and compared with that of other 7-oxabicyclo[2.2.1[heptan-2-one derivatives. I ...

alpha-Hydroxymethylen-verlängerte Aldehyde durch schonende Reduktion von Cyanhydrinen

The OH group in cyanohydrins RR1C(OH)CN [R = Me2CH, R1 = H; R = R1 = Me; RR1 = (CH2)4, (CH2)5] was protected with EtOCH:CH2 to give RR1C(CN)OCHMeOEt, which were then reduced by NaAlH2(OCH2CH2OMe)2 to RR1C(CHO)OCHMeOEt (I) (53-70%), which were hydrolyzed wi ...
