Three representative cases are discussed: stationary cellular flow, stationary shear flow, and percolating flow. Production terms of Fisher-Kolmogorov-Petrovskii-Piskunov type and of Arrhenius type are considered under the assumption of no feedback of the concentration on the velocity. Numerical simulations of advection-reaction-diffusion equations have been performed by an algorithm based on discrete-time maps. The results show a generic enhancement of the speed of front propagation by the underlying flow. For small molecular diffusivity, the front speed Vf depends on the typical flow velocity U as a power law with an exponent depending on the topological properties of the flow, and on the ratio of reactive and advective time scales. For open-streamline flows we find always Vf~U, whereas for cellular flows we observe Vf~U1/4 for fast advection and Vf~U3/4 for slow advection.}, language = {en} } @book{Addison2001, author = {Addison, John T.}, title = {Principles of market-oriented labor market policies}, series = {Diskussionsbeitrag / Europ{\"a}isches Institut f{\"u}r internationale Wirtschaftsbeziehungen, Potsdam}, volume = {84}, journal = {Diskussionsbeitrag / Europ{\"a}isches Institut f{\"u}r internationale Wirtschaftsbeziehungen, Potsdam}, publisher = {Univ.}, address = {Potsdam}, issn = {1430-5445}, pages = {24 S.}, year = {2001}, language = {en} } @article{AfshaarvahidHeuerMenzeletal.2001, author = {Afshaarvahid, Shahraam and Heuer, Axel and Menzel, Ralf and Munch, Jesper}, title = {Temporal structure of stimulated-Brillouin-scattering reflectivity considering transversal-mode development}, year = {2001}, language = {en} } @phdthesis{Ahlers2001, author = {Ahlers, Volker}, title = {Scaling and synchronization in deterministic and stochastic nonlinear dynamical systems}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-0000320}, school = {Universit{\"a}t Potsdam}, year = {2001}, abstract = {Gegenstand dieser Arbeit ist die Untersuchung universeller Skalengesetze, die in gekoppelten chaotischen Systemen beobachtet werden.

In this paper we show how to use relational modeling techniques and relational database technology for modeling and storing biological sequence data, i.e. for data maintained in collections like EMBL or SWISS-PROT to better serve the needs for these application domains. For this reason we propose a two step approach. First, we model the structure (and therefore the meaning of the) data using an Entity-Relationship approach. The ER model leads to a clean design of a relational database schema for storing and retrieving the DNA and protein data extracted from various sources. Our approach provides the clean basis for building complex biological applications that are more amenable to changes and software ports than their file-base counterparts.}, language = {en} } @article{BesnardHunter2001, author = {Besnard, Philippe and Hunter, Anthony}, title = {A logic-based theory of deductive arguments}, issn = {0004-3702}, year = {2001}, language = {en} } @book{Blaszczak2001, author = {Blaszczak, Joanna}, title = {Covert Movement and the Genitive of Negative in Polish}, publisher = {Univ.-Bibliothek Publ.-Stelle}, address = {Potsdam}, isbn = {978-3-935024-36-5}, issn = {1616-7392}, pages = {85 S.}, year = {2001}, language = {en} } @book{Blaszczak2001, author = {Blaszczak, Joanna}, title = {Investigation into the interaction between the indefinites and negation}, series = {Studia grammatica}, volume = {51}, journal = {Studia grammatica}, publisher = {Akad.-Verl.}, address = {Berlin}, isbn = {3-05-003671-0}, pages = {XV, 469 S.}, year = {2001}, language = {en} } @book{BlaszczakFischer2001, author = {Blaszczak, Joanna and Fischer, Susann}, title = {Multiple Wh-Konstruktionen im Slavischen : state of the art report}, issn = {1864-1857}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-10973}, publisher = {Universit{\"a}t Potsdam}, year = {2001}, abstract = {Die vorliegende Arbeit stellt eine kritische {\"U}bersicht {\"u}ber den Forschungsstand zu multiplen Wh-Konstruktionen im Slavischen dar.

In German-speaking plant geography, they are known as "Stromtalpflanzen". The aim of this paper is to review the literature about definitions, explanations and species characteristics and to suggest future directions in research concerning this species group. Results A preliminary list contains 129 ecologically heterogeneous plant species. The mechanisms generating the peculiar distribution pattern may include hydrochory along river corridors, high level of disturbance by water, variable water availability including inundation and summer drought, warm summers, and high nutrient supply on alluvial soils. There is evidence from observational studies for all above mechanisms. However, none of them has been tested experimentally. Demographic data of river corridor plants is limited to very few species, including mainly invasive annuals (Artemisia annua, Bidens frondosa, Cuscuta campestris, Xanthium albinum) and annual (hemi)parasites (Cuscuta campestris, Melampyrum cristatum). Metapopulation studies do not exist to date for European species. part from their habitat requirements, river corridor plants were grouped according to their similarities in overall distribution pattern or in their distribution within particular river corridors. Main conclusions River corridor plants include a high proportion of threatened plant species. In order to preserve them, and in order to understand the mechanisms generating the peculiar distribution pattern, much more has to be known about their population biology and metapopulation dynamics.}, language = {en} } @article{BoeckmannBrueckner2001, author = {B{\"o}ckmann, Christine and Br{\"u}ckner, Axel}, title = {100 years of the Runge-Kutta method : a brief editing for schools}, issn = {0268-3679}, year = {2001}, abstract = {This paper reports on the historical development of the Runge-Kutta methods beginning with the simple Euler method up to an embedded 13-stage method.
