This encouraging course seems to hold on for many aspects in technology. Many efforts were made in the area of computer technology employing mechanisms known from biological systems. The most known examples are evolutionary algorithms and the artificial immune system. One application is in network security, e.g. for the search for viruses and worms, where the immune system was used as an inspiration.In contrast, the focus of our group lays on trying to map the cellular and molecular biology to networking architectures. Recently, it was shown that the known approaches to study effects in computer networking, especially methods to analyze the behavior of large scale networks suffer from many presumptions. We try to study this behavior by analyzing the internal functioning of network components as well as there interactions in comparison with cellular systems and the associated intra and extra cellular signaling pathways.The main focus of this work is to show the similarities of computer networks and cellular systems. Based on the knowledge about cellular metabolism, new concepts for the behavior patterns of routers, monitor systems, and firewalls can be deduced and the efficiency of individual sub-systems can be increased. Focusing on examples of hot topics in the computer society, i.e. network security, potential solutions motivated by cellular behavior are currently studied and, hopefully, will soon bring new results in these areas.Independently from these examinations, we try to show the power of our novel approach by introducing the basic mechanisms and interactions as well as a self-evident application. Doing this, we must keep in mind that the deeper the parallels between biology and technology, the more important it is to map the corresponding elements correctly.}}, author = {{Dressler, Falko and Krueger, Bettina}}, booktitle = {{German Conference on Bioinformatics 2004 (GCB 2004), Poster Session}}, title = {{{Cell biology as a key to computer networking}}}, year = {{2004}}, } @inproceedings{54940, abstract = {{Autonomous networking has become the buzzword for attempts of building high-scalable network architectures, which are self-organizing, self-maintaining and self-healing. Few of these approaches were successful and none has shown to provide all the promised functions. We try to study the processes in computer networks using molecular processes as the paradigm. This novel approach shows many similarities between computer networking and cellular mechanisms. In this paper, we focus on the area of network security as one research area with high demand for high-scalable mechanisms providing the needed functionality. After identifying similarities between nature and technology, we discuss potential research domains, which are high potentials for learning directly from biology at the example of security attacks in networks. We see the proposed mechanism as a generic approach for autonomous networking. The countermeasures against attacks in computer networks are only a special example to introduce the mechanisms.}}, author = {{Krueger, Bettina and Dressler, Falko}}, booktitle = {{International IPSI Stockholm Conference: Symposium on Challenges in the Internet and Interdisciplinary Research (IPSI 2004)}}, title = {{{Molecular Processes as a Basis for Autonomous Networking}}}, year = {{2004}}, } @article{22616, author = {{Hinderling, C. and Keles, Y. and Stöckli, T. and Knapp, H. F. and de los Arcos de Pedro, Maria Teresa and Oelhafen, P. and Korczagin, I. and Hempenius, M. A. and Vancso, G. J. and Pugin, R. and Heinzelmann, H.}}, issn = {{0935-9648}}, journal = {{Advanced Materials}}, pages = {{876--879}}, title = {{{Organometallic Block Copolymers as Catalyst Precursors for Templated Carbon Nanotube Growth}}}, doi = {{10.1002/adma.200306447}}, year = {{2004}}, } @article{22615, author = {{de los Arcos de Pedro, Maria Teresa and Garnier, Michael Gunnar and Seo, Jin Won and Oelhafen, Peter and Thommen, Verena and Mathys, Daniel}}, issn = {{1520-6106}}, journal = {{The Journal of Physical Chemistry B}}, pages = {{7728--7734}}, title = {{{The Influence of Catalyst Chemical State and Morphology on Carbon Nanotube Growth}}}, doi = {{10.1021/jp049495v}}, year = {{2004}}, } @inbook{39982, author = {{Kitzerow, Heinz-Siegfried and Reithmaier, J.

One aim of this chapter is to show that microscopic theories, which have been developed for bare semiconductor heterostructures, are also able to describe semiconductor microcavities very well. Therefore, there is no need to phenomenologically introduce polariton-polariton interactions and parametric scattering of cavity polaritons to describe microcavity experiments, but instead a fully microscopic theory based on a Fermionic electron-hole Hamiltonian can be used. The treatment of many-body correlations using the second-order Born approximation and the dynamics-controlled truncation scheme are introduced and analyzed for bare heterostructures. These approaches are able to successfully explain a number of important experimental results which originate from the dynamics of many-body correlations. Then measurements of the nonlinear optical properties of a quantum-well microcavity are described. In these experiments the spectrally- and temporally-resolved nonlinear optical response is studied in detail using a pump-probe geometry. In particular, the polarization and intensity dependencies of the spectral probe reflection changes and their temporal evolution are analyzed. The prominent features of these experiments are well accounted for by the microscopic many-body theory.}}, author = {{Meier, Torsten and Sieh, C. and Koch, S.W. and Lee, Y.-S and Norris, T.B. and Jahnke, F. and Khitrova, G. and Gibbs , H.M.}}, booktitle = {{Optical Microcavities}}, editor = {{Vahala, K.}}, pages = {{239--317}}, publisher = {{World Scientific, Chap. 6}}, title = {{{Nonlinear optical properties of semiconductor quantum wells inside microcavities}}}, doi = {{10.1142/9789812565730_0006}}, year = {{2004}}, } @inproceedings{44122, abstract = {{We demonstrate that interference of optical excitations of regularly arranged metallic nanodots on a waveguide shows spectral signatures of Fano resonances.
